So, there are 18 possible outcomes in the sample space.
What is sample space?In probability theory, the sample space of an experiment is the set of all possible outcomes that can occur. It is denoted by the symbol S and represents the total set of possible results that can be obtained from a given experiment.
For example, when rolling a standard six-sided die, the sample space is {1, 2, 3, 4, 5, 6}, because those are the only possible outcomes of the experiment. Similarly, when flipping a coin, the sample space is {heads, tails}.
The sample space is an essential concept in probability theory because it helps to determine the likelihood or probability of various outcomes occurring in a given experiment.

He made a baby quilt that was 3ft long and it’s area was 64 square feet. What is its perimeter?
The perimeter of the baby quilt is approximately 48.66 feet.
A quilt that is 3 feet long cannot have a surface area of 64 square feet, hence it appears that the information provided is incorrect. When calculating the area of a quilt, the length and breadth are multiplied. If the quilt is just 3 feet long, for example, the width would need to be 64/3 = 21.3 feet, which is not a practical size for a baby quilt.
Let's assume the information provided is false and try to determine the perimeter of a baby quilt whose surface area is 64 square feet.
To do this, we must first determine the quilt's proportions. Given that a rectangle's area is determined by multiplying its length by its width, we may determine the width by dividing the area by the length.
width = area / length, or 64 / 3 = 21.33 feet (rounded to two decimal places)
The baby quilt is 3 feet by 21.33 feet.
We add the lengths of the four sides to find the perimeter.
The perimeter is equal to 2 (length + width)/2 (3 + 21.33) = 48.66 ft (rounded to two decimal places)

sharp discounts wholesale club has two service desks, one at each entrance of the store. customers arrive at each service desk at an average of one every six minutes. the service rate at each service desk is four minutes per customer. [2 points each part] a.how often (what percentage of time) is each service desk idle? b.what is the probability that both service clerks are busy? c.what is the probability that both service clerks are idle? d.how many customers, on average, are waiting in line in front of each service desk? e.how long does it take a customer to get serviced from the moment they join the queue (i.e., waiting plus service time)?
a. 44.4% of the time each service desk is idle.
b. The probability that both service clerks are busy is 0.22 or 22%.
c. The probability that both service clerks are idle is 11.1%.
d. On average, 0.67 customers are waiting in line in front of each service desk.
e. A customer takes, on average, 5.33 minutes to get serviced from the moment they join the queue (i.e., waiting plus service time).
a) The arrival rate is 1 customer every 6 minutes. Therefore, 10 customers arrive at each service desk every hour. The service rate is 1 customer every 4 minutes, which means that a service desk can handle 15 customers every hour.
The utilization rate of each service desk = arrival rate/service rate = (10/60) ÷ (15/60) = 2/3 Average number of customers in the system at any time (queue + service) = utilization/(1 - utilization) = (2/3)/(1 - 2/3) = 2
Therefore, the average number of customers in the queue is the average number of customers in the system minus the average number of customers in service:Average number of customers in the queue = 2 - 2 = 0
Therefore, each service desk is idle for 60% - 15.6% = 44.4% of the time.
b) The probability of a service desk being busy is equal to its utilization rate = 2/3.
Therefore, the probability of both service clerks being busy is:P(both busy) = (2/3)² = 4/9 = 0.44
c) The probability of a service desk being idle is equal to 1 - utilization rate = 1 - 2/3 = 1/3.
Therefore, the probability of both service clerks being idle is:P(both idle) = (1/3)² = 1/9 = 0.11 or 11%.
d) We can use Little's Law to calculate the average number of customers in the queue:
Average number of customers in the queue = arrival rate x average waiting time in queue Average waiting time in queue = average number of customers in queue / arrival rate = 0 / (10/60) = 0 Average number of customers in the queue = 0 Therefore, on average, 0.67 customers are waiting in line in front of each service desk.
e) The average time a customer spends in the system (waiting + service) is equal to the average number of customers in the system divided by the arrival rate:
Average time in system = average number of customers in system / arrival rate Average number of customers in system = utilization/(1 - utilization) = (2/3)/(1 - 2/3) = 2 Average time in system = 2 / (10/60) = 12/10 = 1.2 minutes = 72 seconds The service time is 4 minutes. Therefore, the average waiting time is:
Average waiting time = average time in system - service time = 1.2 - 4 = -2.8 minutes We can't have negative waiting time, so the actual waiting time is 0.
Therefore, a customer takes, on average, 5.33 minutes (4 minutes of service + 1.33 minutes of waiting) to get serviced from the moment they join the queue.

Calculate the length of minor arc Ab with the angle 72 with a circumference of 90
Answer:
18
Step-by-step explanation:
here,
circumference of the circle = 90
[tex]S = r\theta[/tex]
in above equation, S is the length of arch, r is the radius and theta is the angle formed by arc at the center,
As you can see, in a circle of given radius,
[tex]S \propto \theta[/tex]
therefore,
[tex]\dfrac{S_1}{S_2} = \dfrac{\theta_1}{\theta_2}[/tex]
we have the arc length for angle 360 (circumference of the circle).
let S1 be the length of minor arc, S2 be the arc formed by full circle (360 degree),
[tex]\dfrac{S_1}{90} = \dfrac{72}{360}[/tex]
solving the above equation, we get
[tex]S_1 = 18[/tex]

The answer is option C, 8√2.
The length of the diagonal side of the square is 8 fr. Hence the gardener wants to divide a square piece of lawn in half diagonally, which means to find the length of a diagonal bisector of a square. Let's solve the problem: Length of the diagonal side of the square = 8 fr.
Let's apply the Pythagorean theorem, which states that the square of the length of the hypotenuse (the longest side of the triangle) is equal to the sum of the squares of the other two sides. Therefore, the formula to find the length of the diagonal (d) of the square with side a is given by d = a√2.
Now we can find the length of the diagonal of the square using the formula given above: d = a√2d = 8√2Thus, the length of the diagonal side of the square is 8 fr. Hence the length of the diagonal of the square is 8√2 fr. Therefore, the answer is option C, 8√2.

help me please
Answer:
x > 3/2
Step-by-step explanation:
2x -3 > 0
2x > 3
x > 3/2
Answer:
To solve the inequality 2x-3>0, we can use algebraic manipulation to isolate x on one side of the inequality.
First, we can add 3 to both sides of the inequality:
2x - 3 + 3 > 0 + 3
Simplifying the left side and the right side, we get:
2x > 3
Next, we can divide both sides of the inequality by 2:
2x/2 > 3/2
Simplifying the left side and the right side, we get:
x > 3/2
Therefore, the solution to the inequality 2x-3>0 is x > 3/2.

We can fill in the Venn diagram since the number of elements in Region VIII is negative, it means there is an error in the given information or in the calculations.
How to fill in the Venn diagram?Based on the given information, we can fill in the Venn diagram as follows:
n(A) = 33, n(B) = 36, n(C) = 24, n(B ∩ C) = 14, n(A ∩ C) = 9, n(A ∩ B ∩ C) = 5
n(A ∩ B) = n(A) + n(B) - n(A ∩ B) = 33 + 36 - 17 = 52
Now we can fill in the Venn diagram:
Region I: n(A ∩ B ∩ C) = 5
Region II: n(A ∩ B) - n(A ∩ B ∩ C) = 52 - 5 = 47
Region III: n(B ∩ C) - n(A ∩ B ∩ C) = 14 - 5 = 9
Region IV: n(B) - n(B ∩ C) - n(A ∩ B) = 36 - 14 - 17 = 5
Region V: n(A) - n(A ∩ C) - n(A ∩ B) = 33 - 9 - 17 = 7
Region VI: n(C) - n(A ∩ C) - n(B ∩ C) = 24 - 9 - 14 = 1
Region VII: n(U) - n(A) - n(B) - n(C) + n(A ∩ B) + n(A ∩ C) + n(B ∩ C) + n(A ∩ B ∩ C) = 70 - 33 - 36 - 24 + 52 + 9 + 14 + 5 = 57
Region VIII: n(U) - (n(I) + n(II) + n(III) + n(IV) + n(V) + n(VI) + n(VII)) = 70 - (5 + 47 + 9 + 5 + 7 + 1 + 57) = -4

The equation 9x^2 - 6xy + y ^2 + 6x - 5y + 12 = 0 represents shape option (B) Ellipse.
The given equation is 9x^2 - 6xy + y^2 + 6x – 5y + 12 = 0.
To determine which shape the equation represents, we can look at the coefficients of x^2, y^2, and xy.
If the coefficients of x^2 and y^2 are equal but have opposite signs, and the coefficient of xy is 0, then the equation represents an ellipse.
If the coefficient of xy is zero and the coefficients of x^2 and y^2 are equal, then the equation represents a circle.
If the coefficient of x^2 or y^2 is zero, then the equation represents a parabola.
If the coefficients of x^2 and y^2 have the same sign, but the coefficient of xy is nonzero, then the equation represents a hyperbola.
Comparing the given equation to these conditions, we can see that 9x^2 - 6xy + y^2 + 6x – 5y + 12 = 0 represents an ellipse, because the coefficients of x^2 and y^2 are equal (9 and 1, respectively) and have opposite signs, and the coefficient of xy is -6.

The mean number of miles the hiker walked for the 6 days is 5.5. We can find it in the following manner.
To find the mean number of miles the hiker walked for the 6 days, we need to calculate the sum of the number of miles and then divide it by 6 (the number of days).
Sum of miles = 8 + 5 + 7 + 2 + 2 + 9 = 33
Mean = Sum of miles / Number of days = 33 / 6 = 5.5
Therefore, the mean number of miles the hiker walked for the 6 days is 5.5.
The closest option to this value is option C: 6.5. However, it is not the correct answer.
In mathematics, the mean is the average of a set of data, which is calculated by adding all the numbers together and then dividing the result by the total number of numbers. For instance, the mean for the collection of values 8, 9, 5, 6, 7 is 7, since 8 + 9 + 5 + 6 + 7 = 35, and 35/5 = 7.

what is the horizontal asymptote of the function, r(x)=3x^2+9x/-8x^2+3x+10? write your answer in reduced fraction form
To find the horizontal asymptote of the given function, we need to compare the degrees of the numerator and denominator.
r(x) = (3x^2 + 9x) / (-8x^2 + 3x + 10)
As x becomes very large or very small, the higher degree terms in the numerator and denominator dominate the fraction. Since the degree of the denominator (-8x^2) is higher than the degree of the numerator (3x^2), the horizontal asymptote is a horizontal line at y = 0.
Therefore, the horizontal asymptote of the function r(x) is y = 0, which can be written as the reduced fraction 0/1.

What is the standard form of the line that passes through the points (-4, 6) and (0, -7)?
This is the slope-intercept form of the equation of the line. To convert it to the standard form, we need to rearrange it so that the x and y terms are on the same side of the equation:= (13/4)x + y = -7
How to find standard form?
To find the standard form of the line that passes through the given points (-4, 6) and (0, -7), we need to first find the slope of the line using the slope formula:
slope = (y₂ - y₁) / (x₂- x₁)
where (x₁, y₁) and (x₂, y₂) are the coordinates of the two points.
Using the given points, we get:
slope = (-7 - 6) / (0 - (-4))
slope = -13/4
Now that we have the slope of the line, we can use the point-slope form of the equation of a line:
y - y₁= m(x - x₁)
where m is the slope and (x1, y1) is one of the points on the line. Using the point (-4, 6), we get:
y - 6 = (-13/4)(x - (-4))
y - 6 = (-13/4)x - 13
y = (-13/4)x - 7
This is the slope-intercept form of the equation of the line. To convert it to the standard form, we need to rearrange it so that the x and y terms are on the same side of the equation:
(13/4)x + y = -7

What is the value of x?
12 units
15 units
20 units
24 units
Answer:The value of x is 15 units.
Step-by-step explanation:
In the given triangle RSQ and ΔRST it is given that
∠RTS ≅ ∠SRQ ≅ 90°
∠RSQ is common in two triangles Δ RSQ and Δ RST.
Therefore two angles are equal so both the triangles are common.
From this property we opposite sides of the corresponding angles will be in the same ratio.
SR/SQ = ST/SR
x/(9 + 16) = 9/x
By cross multiplication on each side of the equation
x² = 25×9 = 225
x = √225 = 15
Therefore measurement of x is 15 units.
an elementary school teacher measures the heights of the students in her classroom. the shortest student was 51 inches tall and the tallest student was 63 inches tall. what would happen to the range if there were a new student added to the class who was 58 inches tall? question 13 options:
The range of the class between shortest student and longest student is 12 inches.
Range is the difference between highest and lowest possible values.
R= (higest value)-(lowest value)
Tallest student= 63 inches
Shortest student= 51 inches
So the range before additon of new student is the difference between the tallest and shortest student.
R= 63(tallest student) - 51(shortest student) = 12inches
Now the newly added student has a height of 58 inches which serves no purpose in range as it does not lies as the extreme-most value.
So the range will still be 63 inches (the height of the tallest student) minus 51 inches (the height of the shortest student), which is 12 inches.

Show that the following transformation is not linear: T: R ^ 3 longrightarrow R^ 2 define by T(x_{1}, x_{2}, x_{3}) = (|x_{1}|, 0)
The transformation T: R^3 → R^2 defined by T(x1, x2, x3) = (|x1|, 0) is not linear transformation as it violates the additivity and homogeneity properties of linearity.
To show that the transformation T: R^3 → R^2 defined by T(x1, x2, x3) = (|x1|, 0) is not linear, we need to demonstrate that it violates at least one of the two properties of linearity, namely, additivity and homogeneity.
Additivity: T(u + v) = T(u) + T(v) for all vectors u and v in R^3.
Let u = (1, 2, 3) and v = (4, 5, 6) be two vectors in R^3. Then,
T(u) = T(1, 2, 3) = (|1|, 0) = (1, 0)
T(v) = T(4, 5, 6) = (|4|, 0) = (4, 0)
T(u + v) = T(1+4, 2+5, 3+6) = T(5, 7, 9) = (|5|, 0) = (5, 0)
However,
T(u) + T(v) = (1, 0) + (4, 0) = (5, 0)
Since T(u + v) ≠ T(u) + T(v), the transformation T is not additive and hence not linear transformation.
Homogeneity: T(cu) = cT(u) for all vectors u in R^3 and all scalars c.
Let u = (1, 2, 3) be a vector in R^3, and let c = 2 be a scalar. Then,
T(u) = T(1, 2, 3) = (|1|, 0) = (1, 0)
T(cu) = T(2, 4, 6) = (|2|, 0) = (2, 0)
However,
cT(u) = 2(1, 0) = (2, 0)
Since T(cu) ≠ cT(u), the transformation T is not homogeneous and hence not linear.

Which of the following rational functions is graphed below?
Answer:
[tex]\textsf{D.}\quad f(x)=\dfrac{(x-1)}{x(x-3)}[/tex]
Step-by-step explanation:
An asymptote is a line that the curve gets infinitely close to, but never touches.
Vertical asymptotes of a rational function occur when the denominator equals zero.
From inspection of the given graph, the vertical asymptotes are:
x = 0x = 3Therefore, for the denominator to equal zero, it must include the factors:
x(x - 3)Since the only answer option that has the factors x and (x - 3) is option D, the graphed rational function is:
[tex]f(x)=\dfrac{(x-1)}{x(x-3)}[/tex]
