The probability that the word so formed starts with M is 1/6, and the probability that it starts with M and ends with E is 1/30.
i) To find the probability that the word starts with M, we need to consider the total number of possible arrangements of the letters and the number of arrangements that start with M. The word "MOBILE" has 6 letters, so there are 6! = 720 possible arrangements of the letters. To find the number of arrangements that start with M, we can fix the M in the first position and arrange the remaining 5 letters in the remaining positions, which gives us 5! = 120 arrangements. Therefore, the probability that the word starts with M is:
P(starts with M) = number of arrangements that start with M / total number of arrangements
= 120 / 720
= 1/6
ii) To find the probability that the word starts with M and ends with E, we can fix the M in the first position and the E in the last position, and then arrange the remaining 4 letters in the remaining positions. This gives us 4! = 24 arrangements. Therefore, the probability that the word starts with M and ends with E is:
P(starts with M and ends with E) = number of arrangements that start with M and end with E / total number of arrangements
= 24 / 720
= 1/30
Thus, the probability that the word so formed starts with M is 1/6, and the probability that it starts with M and ends with E is 1/30.

if a slope is when xincome in thousands of dollars, then what is the slope when income in dollars? (hint: a one-dollar change has only 1/1000 of the impact of a one-thousand-dollar change.)
If the slope is defined as the change in the dependent variable (y) divided by the change in the independent variable (x), then the slope would depend on how the dependent variable and independent variable are measured.
Assuming that the dependent variable y is some form of economic outcome (e.g., consumption, savings, investment) and the independent variable x is income, then the slope of the relationship would depend on the units in which income is measured.
If income is measured in thousands of dollars, then a one-unit change in income would correspond to a $1,000 change. Therefore, the slope would reflect the change in the economic outcome associated with a $1,000 change in income.

7. A rectangular prism has a volume of 135ft^3. The width of the rectangular prism is (2x+10)ft. The height of the rectangular prism is 5 times it's width. Write a expression that gives the length of the rectangular prism in feet?
A. 4(x+5)/27 B. 27/4(x+5)
C. (2x^2+100)/27. D. 27/(2x^2+100)
The expression that gives the length of the rectangular prism in feet is option D: 27/(2x^2+100).
What is the expression that gives the length of the rectangular prism in feet?The volume of a rectangular prism is given by the formula V = lwh, where l is the length, w is the width, and h is the height.
We are given that the volume of the rectangular prism is 135ft^3, and the width is (2x+10)ft. Also, the height is 5 times the width, so h = 5w.
Substituting these values in the formula for the volume, we get:
135 = l(2x+10)(5w)
Dividing both sides by (2x+10)(5w), we get:
l = 135 / (2x+10)(5w)
l = 135 / [10(x+5)w]
Now we can substitute h = 5w:
l = 135 / [10(x+5)h/5]
l = 135 / [2(x+5)h]
l = 135 / [2(x+5)(5w)]
l = 135 / [10(x+5)^2]
Simplifying the expression, we get:
l = 27 / (2(x+5)^2)
Therefore, the expression that gives the length of the rectangular prism in feet is option D: 27/(2x^2+100).

The location of point B is (4, −2). So the answer is (4, −2).
How to find the location of the point B?To find the location of point B, we can use the midpoint formula, which states that the coordinates of the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) are:
((x1 + x2)/2, (y1 + y2)/2)
In this case, we know that point M is the midpoint of segment AB, and we know the coordinates of point M. We also know the coordinates of point A. So we can use the midpoint formula to solve for the coordinates of point B.
Let's call the coordinates of point B (x, y). We know that point M is the midpoint of segment AB, so we can set up the following equation:
((−2 + x)/2, (2 + y)/2) = (1, 0)
Simplifying this equation, we get:
(−2 + x)/2 = 1 and (2 + y)/2 = 0

Determine the maximum profit if the marginal cost and marginal revenue are given by C'(x) = 20+ x/20 and R'(x) = 40 and fixed cost is $100.00.
The maximum profit is $3,900 if the marginal cost and marginal revenue are given by C'(x) = 20+ x/20 and R'(x) = 40 and fixed cost is $100.00.
In order to determine the maximum profit, we need to find the quantity (x) where the marginal cost (C'(x)) equals the marginal revenue (R'(x)). This is because when these two values are equal, we are maximizing the profit. The given functions are:
C'(x) = 20 + x/20
R'(x) = 40
First, set the marginal cost equal to the marginal revenue:
20 + x/20 = 40
Now, we need to solve for x:
x/20 = 40 - 20
x/20 = 20
x = 20 * 20
x = 400
So, the maximum profit occurs at a quantity of 400 units. To find the total cost (C(x)) and total revenue (R(x)), we need to integrate the marginal cost and marginal revenue functions:
C(x) = ∫(20 + x/20) dx = 20x + x^2/40 + C₁
R(x) = ∫40 dx = 40x + C₂
Since we have a fixed cost of $100, we know that C₁ = 100. We don't need C₂ to find the profit, as it will cancel out when we calculate it. Now, let's find the total cost and total revenue for 400 units:
C(400) = 20(400) + (400)^2/40 + 100 = 8000 + 4000 + 100 = 12100
R(400) = 40(400) = 16000
Finally, calculate the profit (P(x)):
P(x) = R(x) - C(x) = 16000 - 12100 = 3900
Therefore, the maximum profit is $3,900 when producing 400 units.

if the atlanta hawks free throw percentage is 82%, what is the probability that a player for the hawks will make 2 free shots in a row?
Answer:
Approx 67.24%
Step-by-step explanation: If the Atlanta Hawks' free-throw percentage is 82%, the probability that a player will make one free throw is 0.82.
To find the probability that a player will make two free throws in a row, we can use the multiplication rule of probability which states that the probability of two independent events occurring together is the product of their individual probabilities.
Therefore, the probability of a player making two free throws in a row can be calculated as follows:
P(making two free throws in a row) = P(making first free throw) x P(making second free throw)
P(making two free throws in a row) = 0.82 x 0.82
P(making two free throws in a row) = 0.6724 or 67.24%
Therefore, the probability that a player for the Atlanta Hawks will make two free shots in a row is approximately 67.24%

To find the critical points of the function f(x,y) = x' + y - 6y - 3x + 9, we need to take the partial derivatives with respect to x and y and set them equal to zero.
∂f/∂x = -3 = 0
∂f/∂y = 1 - 6 = -5 = 0
So the system of equations is:
-3 = 0

Therefore, the list of critical points is empty.
Hello! I'd be happy to help you find the critical points of the given function. The function is:
f(x,y) = x' + y - 6y? - 3x + 9
To find the critical points, we need to find the partial derivatives of the function with respect to x and y, and then set them equal to zero:
∂f/∂x = ∂(x' + y - 6y? - 3x + 9)/∂x
∂f/∂y = ∂(x' + y - 6y? - 3x + 9)/∂y

95%
188%
nber of Car Buyers
What is the standard deviation: $
Enter your answer in the answer box.
The standard deviation for the prices paid for this particular model of car is $6,250.
How do pay within three standard deviations?Based on the figure you provided, we know that the data is normally distributed and approximately 68% of car buyers pay within one standard deviation of the mean, approximately 95% pay within two standard deviations, and approximately 99.7% pay within three standard deviations.
Since we know that 95% of the prices paid fall within two standard deviations of the mean, we can say that the distance between the mean and the upper or lower limit of this range is equal to two standard deviations. This is also known as the "95% confidence interval."
Therefore, to find the standard deviation, we can calculate the distance between the mean and either the upper or lower limit of the 95% confidence interval and then divide it by two.
From the figure, we can see that the 95% confidence interval extends from approximately $23,500 to $48,500. The midpoint of this interval is approximately $36,000, which we can take as the mean.
So, the distance between the mean and either end of the 95% confidence interval is:
$48,500 - $36,000 = $12,500
Dividing this by two gives us the standard deviation:
$12,500 / 2 = $6,250
Therefore, the standard deviation for the prices paid for this particular model of car is $6,250.

The temperature at any point (x, y) in a steel plate is T = 900 − 0.7x2 − 1.3y2, where x and y are measured in meters. At the point (3, 9), find the rates of change of the temperature with respect to the distances moved along the plate in the directions of the x- and y-axes.
At point (3, 9), the rate of change of temperature with respect to the x-axis is -4.2 °C/m, and with respect to the y-axis, it is -23.4 °C/m.
To find the rates of change of the temperature with respect to the distances moved along the x- and y-axes at point (3, 9), you need to compute the partial derivatives of the temperature function T(x, y) = 900 - 0.7x^2 - 1.3y^2 with respect to x and y.
For the x-axis:
∂T/∂x = -1.4x
At point (3, 9), ∂T/∂x = -1.4(3) = -4.2 °C/m
For the y-axis:
∂T/∂y = -2.6y
At point (3, 9), ∂T/∂y = -2.6(9) = -23.4 °C/m
So, at point (3, 9), the rate of change of temperature with respect to the x-axis is -4.2 °C/m, and with respect to the y-axis, it is -23.4 °C/m.

The diameter of Circle Q terminates on the circumference of the circle at (0,3)and (0,−4). Write the equation of the circle in standard form. Show all of your work.
Need answer ASAP Please!!
Answer:
[tex]x^2+\left(y+\dfrac{1}{2}\right)^2=\dfrac{49}{4}[/tex]
Step-by-step explanation:
The center of the circle is the midpoint of its diameter.
[tex]\boxed{\begin{minipage}{7.4 cm}\underline{Midpoint between two points}\\\\Midpoint $=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)$\\\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the endpoints.\\\end{minipage}}[/tex]
Given the endpoints of the diameter are (0, 3) and (0, -4), to find the coordinates of the center of the circle, substitute the two endpoints into the midpoint formula:
[tex]\text{Center}=\left(\dfrac{0+0}{2},\dfrac{-4+3}{2}\right)=\left(0,-\dfrac{1}{2}\right)[/tex]
As the x-values of the endpoints of the diameter are the same, the length of the diameter, d, is the absolute value of the difference in y-values of the endpoints:
[tex]d=|3-(-4)|=7[/tex]
Therefore, the diameter of circle Q is 7 units.
The radius, r, of a circle is half its diameter. Therefore:
[tex]r=\dfrac{d}{2}=\dfrac{7}{2}[/tex]
[tex]\boxed{\begin{minipage}{4 cm}\underline{Equation of a circle}\\\\$(x-h)^2+(y-k)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(h,k)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]
Now we have determined the center and radius of circle Q, we can substitute these values into the equation of a circle to write the equation of circle Q in standard form:
[tex](x-0)^2+\left(y-\left(-\dfrac{1}{2}\right)\right)^2=\left(\dfrac{7}{2}\right)^2[/tex]
[tex]x^2+\left(y+\dfrac{1}{2}\right)^2=\dfrac{49}{4}[/tex]
Therefore, the equation of circle Q in standard form is:
[tex]\boxed{x^2+\left(y+\dfrac{1}{2}\right)^2=\dfrac{49}{4}}[/tex]

There is 1. 75 liter of water in a rectangular container. The base of the container is square on the side 12 cm and its height is 16. 5 cm. How much more water is needed to fill the container to its brim? Give your answer in liter
0.626 liters of water is needed to fill the container to its brim.
The volume of the rectangular container can be found by multiplying the area of the base (length x width) by the height:
Volume of rectangular container = length x width x height
Since the base is a square with a side of 12 cm, the area of the base is:
Area of base = 12 cm x 12 cm = 144 cm^2
Converting the height to cm, we have:
Height = 16.5 cm
So the volume of the container is:
Volume = 144 cm^2 x 16.5 cm = 2376 cm^3
To convert the volume from cubic centimeters to liters, we divide by 1000:
Volume = 2376 cm^3 ÷ 1000 = 2.376 liters
Since there is already 1.75 liters of water in the container, the amount of water needed to fill the container to its brim is:
Amount of water needed = 2.376 liters - 1.75 liters = 0.626 liters
Therefore, 0.626 liters of water is needed to fill the container to its brim.

centimeters. What is the radius of the cylinder?
Use 3. 14 for T.
Need answer ASAP right now
The radius of the cylinder with volume of 141.3and height of 7 cm is 2.53cm.
The formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height. Given that V = 141.3 cm³ and using π ≈ 3.14, we can solve for r.
Rearranging the formula, we get r² = V/(πh), and plugging in the given values, we get r² = 141.3/(3.14*7). Since we don't know the height of the cylinder, we cannot solve for r exactly.
However, we can say that the radius of the cylinder is proportional to the square root of the volume, the height is 7 cm, then r = √(141.3/3.14*7) ≈ 2.53cm. If the height is different, the radius will change accordingly.
In summary, using the formula for the volume of a cylinder andheight of 7 cm, the radius of the cylinder with volume 141.3 cm³ and using π ≈ 3.14 is approximately 2.53 cm.

The technician will bill a total of 150 hours to the job. To find the total hours, we need to determine how many hours the technician will work during the first three weeks and the last three weeks, and then add them together.
1. First three weeks:
The technician will be 25% billable during these weeks. They work 40 hours per week, so we need to calculate 25% of 40 hours for each week:
25% of 40 hours = 0.25 * 40 = 10 hours per week
Since there are three weeks, we'll multiply these hours by 3:
10 hours/week * 3 weeks = 30 hours
2. Last three weeks:
The technician will be 100% billable during these weeks. They work 40 hours per week, so they'll bill 40 hours for each of these weeks:
40 hours/week * 3 weeks = 120 hours
3. Finally,
we need to add the hours from the first and last three weeks together to find the total hours the technician will bill to the job:

In ms. Oaks class 5/12 of the students wear glasses, 2/9 of the students wear earrings, 2/18 of the students wear hats, and 1/4 of the students wear a watch. No one wears more than one of these items. 4 students wear hats.
A. How many students are in ms. Oaks class?
b. Determine how many students wear each type of item.
please explain how you got the answer, im having trouble figuring out how to find the answer
There are 36 students in Ms. Oaks' class. The number of students who wear each type of item is: Glasses: 15 students, Earrings: 8 students, Hats: 4 students and Watch: 9 students
Let the total number of students in Ms. Oaks' class be x.
a) We know that 2/18 of the students wear hats, which is equivalent to 1/9 of the students. We are also told that 4 students wear hats. So, we can set up an equation:
1/9 * x = 4
Solving for x, we get:
x = 36
Therefore, there are 36 students in Ms. Oaks' class.
b) We can now use the information given to determine how many students wear each type of item.
- Glasses: 5/12 of the students wear glasses, which is equivalent to:
(5/12) * 36 = 15 students
- Earrings: 2/9 of the students wear earrings, which is equivalent to:
(2/9) * 36 = 8 students
- Hats: We are told that 4 students wear hats.
- Watch: 1/4 of the students wear a watch, which is equivalent to:
(1/4) * 36 = 9 students
Therefore, the number of students who wear each type of item is:
Glasses: 15 students
Earrings: 8 students
Hats: 4 students
Watch: 9 students

007 10.0 points An advertisement is run to stimulate the sale of cars. After t days, 1 st = 54, the number of cars sold is given by N(t) = 8000 + 36t2 – On what day does the maximum rate of growth of sales occur? 1. on day 12 2. on day 11 3. on day 14 4. on day 10 5. on day 13
The advertisement generates the maximum rate of growth of car sales on the first day.
How to find the day of maximum growth rate?The rate of growth of sales is given by the derivative of N(t) with respect to time t:
dN/dt = 72t
To find the day when the maximum rate of growth of sales occurs, we need to find the value of t that maximizes this expression.
Setting dN/dt = 0, we get:
72t = 0
t = 0
However, since we are interested in finding the day when the maximum rate of growth of sales occurs, we need to consider the second derivative of N(t):
d2N/dt2 = 72
Since this is a positive constant, it tells us that N(t) is a convex function and has a minimum value at t = 0. Therefore, the maximum rate of growth of sales occurs on the day when t = 0, which corresponds to the first day of the advertisement.
Answer: 1. on day 12

company A charges $50 per month plus $0.05 per minute. Company B has no monthly charge but charges $0.15 per minute. When is the charge for the companies the same?
The charge for the companies is the same at 500 minutes
When is the charge for the companies the same?From the question, we have the following parameters that can be used in our computation:
Company A charges $50 per month plus $0.05 per minute. Company B has no monthly charge but charges $0.15 per minute.This means that
A(x) = 50 + 0.05x
B(x) = 0.15x
When the charge for the companies are the same, we have
0.15x = 50 + 0.05x
So, we have
0.1x = 50
Divide
x = 500
Hence, the number of minutes is 500

Elizabeth is considering buying a $30,000 car. Which of these financing options
will likely lead to the LOWEST monthly payment?
$3000 down payment, 6% interest, 84 months
$3000 down payment, 6% interest, 60 months
$0 down payment, 6% interest, 60 months
$0 down payment, 0% interest, 36 months
The financing option that will likely lead to the lowest monthly payment is:
$3000 down payment, 6% interest, 84 months
The longer loan term (84 months) will spread out the payments over a longer period of time, resulting in a lower monthly payment. The down payment will also help to reduce the monthly payment amount.
The 6% interest rate is relatively low, so it won't have a significant impact on the monthly payment compared to the loan term.

Consider the function f(x) = x^3 – 5x on the closed interval [ - 1,3). Find the exact value of the slope of the secant line connecting ( - 1, f( - 1)) and (3, f(3)). m = ?
To find the slope of the secant line connecting two points on a curve, we can use the formula: slope of secant line = (change in y) / (change in x).
In this problem, we are given the function f(x) = x^3 - 5x on the closed interval [-1, 3), and we need to find the slope of the secant line connecting (-1, f(-1)) and (3, f(3)). To do this, we first need to find the y-coordinates of these points by plugging the given x-values into the function f(x). Then, we can use the formula for the slope of a secant line to find the slope of the line connecting these two points.
The slope of a secant line is an important concept in calculus and is used to approximate the instantaneous rate of change of a function at a particular point.
