The equation 24b = t is used to find b, the cost of 1 bottle of water when sold in a 24‐pack case with a case price of t dollars. What is the cost of 1 bottle of water when the case price is $7.50?
Answers
The cost of 1 bottle of water when sold in a 24-pack case with a case price of $7.50 is $0.3125 or 31.25 cents.
The given equation is 24b = t, where b is the cost of one bottle of water and t is the price of a case of 24 bottles.
We are given that the price of the case is $7.50. Substituting this value in the equation, we get:
24b = 7.50
To solve for b, we need to isolate it on one side of the equation. We can do this by dividing both sides by 24:
b = 7.50/24
Simplifying this expression, we get:
b = 0.3125
Therefore, the cost of 1 bottle of water when sold in a 24-pack case with a case price of $7.50 is $0.3125 or 31.25 cents. In other words, if you were to buy a case of 24 bottles of water for $7.50, each bottle of water would cost you about 31.25 cents.

2. In March, Sunshine Kindergarten was given a sum of $2000. It spent 10% of the sum given on books, 70% on food and the rest on cleaning services. In April the sum given was reduced. The kindergarten spent the same amount of money on books and reduced its spending of food by $240. It spent the remaining 20% of the sum given in April on cleaning services. By what percentage was the sum given to the kindergarten reduced?
Answers
The sum given to the kindergarten was reduced by 15%.
How to solve this problemLet's first find out how much money the kindergarten spent in March:
Books: 10% of $2000 = 0.1 x $2000 = $200Food: 70% of $2000 = 0.7 x $2000 = $1400Cleaning services: $2000 - $200 - $1400 = $400So, in April, the kindergarten spent the same amount on books, which was $200. It also reduced its spending on food by $240, which means it spent:
Food: $1400 - $240 = $1160
The remaining 20% of the sum given in April was spent on cleaning services, which means:
Cleaning services: 20% of sum given in April = 0.2 x $x (where x is the sum given in April)
We can set up an equation based on the above information:
$200 + $1160 + 0.2x = x
Simplifying and solving for "x":
$1360 + 0.2x = x
0.8x = $1360
x = $1700
Therefore, the sum given to the kindergarten in April was $1700, which means it was reduced by:
($2000 - $1700) / $2000 x 100% = 15%
So, the sum given to the kindergarten was reduced by 15%.

cart a with mass m travels in the x direction with a speed of 4 m/s. it collides with car t b, which has mass 3m and is initially at rest. after the collision, cart a moves in the -x direction and cart b moves in the x direction. assume that the collision was perfectly elastic
Answers
After the collision, cart a moves in the negative x direction with a speed of 4 m/s, and cart b moves in the positive x direction with a speed of 2 m/s.
In a perfectly elastic collision, the total momentum of the system is conserved, as well as the total kinetic energy. This means that the sum of the momenta of the carts before the collision is equal to the sum of the momenta after the collision. In this case, since cart b is initially at rest, its initial momentum is zero.
We can use conservation of momentum to determine the final velocities of the carts. Let the velocity of cart b after the collision be v, then the velocity of cart a after the collision is -4 m/s. The momentum of cart a before the collision is m(4 m/s) = 4m, and the momentum of cart b after the collision is 3mv.
Using conservation of momentum, we have:
m(4 m/s) + 0 = m(-4 m/s) + 3mv
Simplifying this equation, we get:
8m = 3mv + 4m
Dividing both sides by 3m, we get:
v = (8/3) - (4/3)v
Solving for v, we get:
v = 2 m/s
So after the collision, cart a moves in the negative x direction with a speed of 4 m/s, and cart b moves in the positive x direction with a speed of 2 m/s. We can verify that this satisfies conservation of momentum:
m(4 m/s) + 0 = m(-4 m/s) + 3m(2 m/s)
4m = 4m
This result shows that in a perfectly elastic collision, even though the carts exchange momentum, the total momentum of the system is conserved.

The equation of the tangent line is y = -x/3 + 1/3 where
m = -1/3 and b = 1/3What is the equation of a tangent line to a curve?The equation of a tangent line to a curve is the equation of the line that touches the curve at that point and tangent to it.
To find the equation of the tangent line to the curve y = 1/(3sinx + 3cosx) at (0, 1/3), we know that the value of the tangent at that point is the derivative of the curve at that point.
so, differentiating y wiith respect to x, we have
y = 1/(3sinx + 3cosx)
= (3sinx + 3cosx)⁻¹
Let u = 3sinx + 3cosx
y = u⁻¹
dy/dx = du⁻¹/du du/dx
= -u⁻² du/dx
Now du/dx = d(3sinx + 3cosx)/dx
= d3sinx/dx + d3cosx/dx
= 3cosx - 3sinx
So, dy/dx = -u⁻² du/dx
= -(3sinx + 3cosx)⁻²(3cosx - 3sinx)
= -(3cosx - 3sinx)/3sinx + 3cosx)²
Now, at (0, 1/3)
dy/dx = -(3cosx - 3sinx)/3sinx + 3cosx)²
= -(3cos0 - 3sin0)/3sin0 + 3cos0)²
= -[3(1) - 3(0)]/[3(0) + 3(1))²
= -[3 - 0]/[0 + 3)²
= -3/3²
= -1/3
Now, the equation of a line in slope form passing through the point (x', y') is
(y - y')/(x - x') = m where m = slope
For the tangent line
m = dy/dx = -1/3, x = 0 and y = 1/3So, substituting the values of the variables into the equation we have
(y - y')/(x - x') = m
(y - 1/3)/(x - 0) = -1/3
(y - 1/3)/x = -1/3
y - 1/3 = -x/3
y = -x/3 + 1/3
Comparing this with the equation of a line in slope-intercept form y = mx + b where m = slope and b = y-intercept
m = -1/3 and b = 1/3So, the equation of the tangent line is y = -x/3 + 1/3 where

Use numbers 0-9 so that each problem

17 1
Answers
Answer: See below
Step-by-step explanation:
To solve this problem, we need to assign each digit from 0 to 9 to a unique letter so that each letter represents a single digit. We can then use this mapping to solve the addition problem:
Let's assign the letters A, B, C, D, E, F, G, H, I, and J to the digits 0 to 9, respectively.
Then, the addition problem becomes:
A B C
D E F
We know that the sum of each column must be the same, so:
C + F = 10 + B
B + E = 10 + A
We can rewrite these equations as:
C - B + F = 10
B - A + E = 10
Since we are given that the sum of the two numbers is the same, we know that:
C + F + D + E = 1112
We can substitute C and F in terms of A and B using the equations above:
C = 10 + B - F
F = 10 + C - B
Substituting these expressions into the equation for the sum, we get:
10 + B - F + C + D + E = 1112
Simplifying this equation, we get:
B - F + C + D + E = 1102
Now we can substitute in the expressions for C and F in terms of A and B:
B - (10 + B - F) + (10 + C - B) + D + E = 1102
Simplifying and canceling out terms, we get:
F - C - D - E = -92
We know that each digit is unique, so we can assume that A is not equal to 0 (otherwise the number would not have 4 digits). We can also assume that D is not equal to 0, since it is the leftmost digit of the second number.
Trying different values for A and D, we find that A = 2 and D = 3 works:
A B C

Answer choices are rounded to the hundredths place.
Answers
Answer:0.65
Step-by-step explanation:
The standard error of the sample mean is approximately 0.682, rounded to the hundredths place.
To calculate the standard error of the sample mean, we need to find the sample mean and the standard deviation of the data. Then we can divide the standard deviation by the square root of the sample size.
First, let's calculate the sample mean:
Mean = (64.5 + 64 + 66.5 + 64 + 62.5 + 61 + 63) / 7 = 64.14
Next, let's calculate the standard deviation. We will use the sample formula for standard deviation (Bessel's correction):
Calculate the squared differences from the mean for each temperature:
(64.5 - 64.14)² = 0.1904
(64 - 64.14)² = 0.0204
(66.5 - 64.14)² = 5.5376
(64 - 64.14)² = 0.0204
(62.5 - 64.14)² = 2.6836
(61 - 64.14)² = 9.8324
(63 - 64.14)² = 1.2696
Calculate the sum of the squared differences:
Sum = 0.1904 + 0.0204 + 5.5376 + 0.0204 + 2.6836 + 9.8324 + 1.2696 = 19.5544
Calculate the variance:
Variance = Sum / (n - 1) = 19.5544 / (7 - 1) = 3.25907
Calculate the standard deviation:
Standard Deviation = sqrt(Variance) = sqrt(3.25907) = 1.80597
Finally, let's calculate the standard error of the sample mean:
Standard Error = Standard Deviation / sqrt(n) = 1.80597 / sqrt(7) ≈ 0.682
Therefore, the standard error of the sample mean is approximately 0.682, rounded to the hundredths place.

Step-by-step explanation:
First Add both equations

so we get, 4x=12
so x=3
Now plug x back into equation 2 so we get y=2
Step-by-step explanation:
that means we optionally multiply one or both equations with some factors, so that one variable term has the same coefficient in both equations but with different signs.
and then we add both equations giving us one equation in the other variable, which we can solve.
and then we use that with any of the original equations to solve for the first variable.
in this case we don't need the multiplication step, as the terms in y have already the same coefficient (1) with different signs.
so, we add both equations
3x - y = 7
+ x + y = 5
------------------
4x 0 = 12
4x = 12
x = 12/4 = 3
x + y = 5

c) What is the probability that the people of Seattle get to wait at least 3 days until it rains for the first time in the New Year?
d) How many days, on average, do they wait for the first day of rain in the New Year?
e) If X = the number of days until it rains for the first time, is X binomial or geometric or neither? Explain.
Answers
(a) The probability of rain on January 1st is 0.614. (b) The probability of rain for the first time in the New Year on January 3rd is 0.136*0.614 = 0.083. (c) the probability that people of Seattle get to wait at least 3 days until it rains for the first time in the New Year is 0.053. (d) They wait for the first day of rain in the New Year is 1/0.614 ≈ 1.63 days. (e) The distribution of X is a geometric distribution.
a) The probability that it will rain on January 1st can be estimated using the information provided by komonews.com, which states that the chances of rain on any day in the first week of January in Seattle is about 0.614. Assuming that the probability of rain is constant across all days of the week, the probability of rain on January 1st is also 0.614.
b) The probability that it will rain for the first time in the New Year on January 3rd can be calculated by considering the probability of no rain for the first two days, followed by rain on the third day. The probability of no rain for the first two days is [tex](1-0.614)^2[/tex] = 0.136, and the probability of rain on the third day is 0.614. Therefore, the probability of rain for the first time in the New Year on January 3rd is 0.136*0.614 = 0.083.
c) The probability that the people of Seattle get to wait at least 3 days until it rains for the first time in the New Year can be calculated by considering the probability of no rain for the first three days. The probability of no rain for the first three days is [tex](1-0.614)^3[/tex] = 0.053. Therefore, the probability that people of Seattle get to wait at least 3 days until it rains for the first time in the New Year is 0.053.
d) The expected value or average of the number of days people in Seattle wait for the first day of rain in the New Year can be calculated by using the formula E(X) = 1/p, where p is the probability of rain on any given day. Therefore, the expected value or average number of days people in Seattle wait for the first day of rain in the New Year is 1/0.614 ≈ 1.63 days.
e) The number of days until it rains for the first time in the New Year, X, is a geometric random variable since it represents the number of trials until the first success (rain). The probability of success (rain) remains constant over time, and the trials (days) are independent of each other. Therefore, the distribution of X is a geometric distribution.

A committee of 8 people is to be chosen from 7 men and 5 women. What is the number of committee if a) the committee contains at least 3 men and at least 3 women, b) the oldest man or the oldest woman, but not both, must be included in the committee?
Answers
Answer:196 possible committees
Step-by-step explanation:
Part (a): Three cases:
Case 1: 3 men and 5 women: (7 C 3) * (5 C 5) = 35 * 1 = 35; or
Case 2: 4 men and 4 women: (7 C 4) * (5 C 4) = 35 * 5 = 175; or
Case 3: 5 men and 3 women: (7 C 5) * (5 C 3) = 21 * 10 = 210
35 + 175 + 210 = 420 possible committees
Part (b): Six cases:
Cases 1–3: Oldest man included (but not oldest woman):
Case 1: 3 men and 5 women: Not possible**; therefore, 0; or
Case 2: 4 men and 4 women: 1 * (6 C 3) * (4 C 4) = 20 * 1 = 20; or
Case 3: 5 men and 3 women: 1 * (6 C 4) * (4 C 3) = 15 * 4 = 60; or
Cases 4–6: Oldest woman included (but not oldest man):
Case 4: 3 men and 5 women: (6 C 3) * (5 C 5) = 20 * 1 = 20; or
Case 5: 4 men and 4 women: (6 C 4) * 1 * (4 C 3) = 15 * 4 = 60; or
Case 6: 5 men and 3 women: (6 C 5) * 1 * (4 C 2) = 6 * 6 = 36
0 + 20 + 60 + 20 + 60 + 36 = 196 possible committees

Answers
The surface area of the given triangular prism having an isosceles triangle base with sides 40,41 and 43 cm, is 2274 cm².
What is area?Area is a measure of the size of a two-dimensional shape or surface, such as a rectangle, triangle, circle, or any other shape that has length and width. It is usually expressed in square units, such as square meters, square centimeters, square feet, or square inches.
To find the surface area of a triangular prism, we need to find the area of each face of the prism and add them up.
The triangular base of the prism is an isosceles triangle with sides of 40 cm, 41 cm, and 43 cm.We may use Heron's formula to determine the area of this triangle:
s = (40 + 41 + 43) / 2 = 62
A = √(s(s-40)(s-41)(s-43)) = √(622221*19) = 798
Therefore, the area of the triangular base is 798 cm².
The height of the prism is given as 18 cm, which is also the length of the rectangular side of the prism.
The two other faces of the prism are rectangles with lengths equal to the base of the triangle (41 cm), and widths equal to the height of the prism (18 cm). The area of each rectangle is:
A = lw = 4118 = 738
Therefore, the area of both rectangles is 2*738 = 1476 cm².
The total surface area of the prism is the sum of the area of the base and the area of both rectangular sides:
Total surface area = Area of base + 2*(Area of rectangle)
Total surface area = 798 + 2*738
Total surface area = 2274 cm².

Statement (A) is true, Statement (B) is false, Statement (C) is true, Statement (D) is true and Statement (E) is false.
The given information is that P(odd) = 1/3
where odd numbers are 3 and 5, and there are two odd-numbered sections out of six equal sections.
(A) The probability of landing on an odd-numbered section is not exactly 33.33%, but approximately equal to 33.33% or 1/3.
So, statement (A) is true.
(B) The probability of landing on an even-numbered section is not exactly 66.67%, but approximately equal to 66.67% or 2/3.
So, statement (B) is false.
(C) The probability of landing on an odd-numbered section is given as 1/3, which is less than the probability of landing on an even-numbered section, which is 2/3. Therefore, statement (C) is true.
(D) It is given that one of the sections is numbered 6. So, it is not impossible to land on 6. Therefore, statement (D) is false.
(E) To determine if the spinner is fair, we need to know the probability of each outcome, which is not provided in the given information. Therefore, we cannot determine if the spinner is fair or not based on the information given. So, statement (E) is uncertain.
Therefore, the true statements about this game are (A), (C), and (D).

What is the probability that the code number for a new customer will begin with the number 7?
Answers
Answer:
Cannot be determined
Step-by-step explanation:
Without any additional information, we cannot accurately determine the probability that the code number for a new customer will begin with the number 7.
To calculate the probability, we would need to know the total number of possible code numbers that can be assigned to new customers and how many of those code numbers start with the number 7. If we have that information, we can calculate the probability as follows:
Probability = Number of code numbers starting with 7 / Total number of possible code numbers
For example, if there are 1000 possible code numbers and 50 of them start with the number 7, the probability of a new customer's code number starting with 7 would be:
Probability = 50 / 1000
Probability = 0.05 or 5%

Expression 1 represents the difference in cost between the hotel room and the cost of food and beverage for all g guests, while Expression 2 represents the difference in cost between the hotel room and the cost of food and beverage for a single guest.
Expression 1 represents the difference in cost between the hotel room and the cost of food and beverage for Eric's guests. The first part of the expression (326 + 37g) represents the cost of the hotel room for all g guests, while the second part of the expression (287 + 23g) represents the cost of food and beverage for all g guests. To calculate the total cost of the hotel room and food and beverage, we can use the following formula: (326 + 37g) - (287 + 23g) = 39 + 14g.Expression 2, on the other hand, represents the difference in cost between the hotel room and the cost of food and beverage for a single guest. The first part of the expression (38 + 14g) represents the cost of the hotel room for one guest, while the second part of the expression (287 + 23g) represents the cost of food and beverage for one guest. To calculate the total cost of the hotel room and food and beverage for one guest, we can use the following formula: 38 + 14g.In conclusion, Expression 1 represents the difference in cost between the hotel room and the cost of food and beverage for all g guests, while Expression 2 represents the difference in cost between the hotel room and the cost of food and beverage for a single guest.

3 1/5 divided by 1 7/9 in simplest form
Answers
Answer:
To divide two mixed numbers, we first need to convert them into improper fractions.
Converting 3 1/5 to an improper fraction:
3 1/5 = (3 × 5 + 1) / 5 = 16/5
Converting 1 7/9 to an improper fraction:
1 7/9 = (1 × 9 + 7) / 9 = 16/9
