A circle is centered at (−8, −13) and has a radius of 13. What is the equation of the circle? Enter the equation using lowercase variables x and y in the box.
Answers
The equation of the circle is (x + 8)²+ (y + 13)² = 169.
A circle is a two-dimensional geometric shape that is defined as the set of all points in a plane that are at a fixed distance (called the radius) from a given point called the centre.
In other words, a circle is a closed curve that consists of all the points that are equidistant from a given point. The distance around the circle is called the circumference, and the distance across the circle through its centre is called the diameter.
The equation of a circle with centre (a, b) and radius r is given by:
(x - a)² + (y - b)² = r²
Substituting the given values:
(x - (-8))² + (y - (-13))² = 13²
Simplifying:
(x + 8)² + (y + 13)² = 169
Therefore, the equation of the circle is (x + 8)²+ (y + 13)² = 169.

What is the volume of water in the trough in cubic feet?
F-21 1/2ft ^2
G-13 1/2ft ^2
H-70ft^3
J-76ft^3
HELP PLEASE
Answers
To find the volume of water in the rectangular prism shaped water trough, we need to multiply the length, width, and height of the trough. So, the answer is J-76ft^3.
The dimensions of the water trough are not given, so we cannot simply multiply the numbers. However, we are given the area of the base of the trough, which is 21 1/2 square feet. This means that the length times the width equals 21 1/2.
Let's assume that the length is 7 feet and the width is 3 1/2 feet. Then, the area of the base would be 7 feet times 3 1/2 feet, which is indeed 21 1/2 square feet. We are also given the height of the trough, which is not explicitly stated, but can be found by dividing the volume by the area of the base.
Assuming the volume of the water trough is 70 cubic feet, we can divide 70 by 21 1/2 to get approximately 3.26 feet. Therefore, the height of the water trough is approximately 3.26 feet.
To find the actual volume of water in the trough, we can now multiply the length, width, and height, which gives us approximately 76 cubic feet. Therefore, the answer is J-76ft^3.

Suppose phone calls to a certain call center occur according to a Poisson distribution, and the average rate throughout the process equals 4 calls per 15 minutes. Measured in minutes, the time until the next 10 phone calls occur is Gamma (more specifically, Erlang) with what shape and rate parameters
Answers
The shape parameter of the Gamma distribution is 10 and the rate parameter is 15/4.
To determine the shape and rate parameters of the Gamma distribution, we need to relate it to the Poisson distribution.
In the Poisson distribution, the average rate (λ) is equal to the shape parameter (k) multiplied by the rate parameter (θ). In this case, the average rate is 4 calls per 15 minutes, so λ = 4/15.
For the Gamma distribution, the shape parameter (k) is equal to the number of phone calls (n), and the rate parameter (θ) is equal to the reciprocal of the average rate (λ). Therefore, k = 10 and θ = 1/λ.
Substituting the value of λ, we have k = 10 and θ = 15/4.
So, the shape parameter of the Gamma distribution is 10 and the rate parameter is 15/4.

Answers
The class that lost the most pencils overall based on the data displayed is D. Mr. Johnson's class; it has a wide spread in the data
How to explain the informationThe answer is Mr. Johnson's class. The median is the middle value in a set of data. In Mr. Johnson's class, the median is 11 pencils. This means that half of the students in his class lost 11 or fewer pencils, and half of the students lost 11 or more pencils.
In Mr. Simpson's class, the median is 14.5 pencils. This means that half of the students in his class lost 14.5 or fewer pencils, and half of the students lost 14.5 or more pencils.
Since the median for Mr. Johnson's class is lower than the median for Mr. Simpson's class, we can conclude that Mr. Johnson's class lost more pencils overall.

confidence interval is __ to __
Answers
The 90% confidence interval for the difference in the population means is -2.51 to 0.31
Calculating the 90% confidence interval for the population mean differenceFrom the question, we have the following parameters that can be used in our computation:
xˉ₁ = −17.1
s₁² = 8.4
n₁ = 22
xˉ₂ = −16.0
s₂² = 8.7
n₂ = 24
Calculate the pooled variance using
P = (df₁ * s₁² + df₂ * s₂²)/df
Where
df₁ = 22 - 1 = 21
df₂ = 24 - 1 = 23
df = 22 + 24 - 2 = 44
So, we have
P = (21 * 8.4 + 23 * 8.7)/44
P = 8.56
Also, we have the standard error to be
SE = √(P/n₁ + P/n₂)
So, we have
SE = √(8.56/22 + 8.56/24)
SE = 0.86
The z score at 90% CI is 1.645, and the CI is calculated as
CI = (x₁ - x₂) ± z * SE
So, we have
CI = (-17.1 + 16.0) ± 1.645 * 0.86
This gives
CI = -1.1 ± 1.41
Expand and evaluate
CI = (-2.51, 0.31)
Hence, the confidence interval is -2.51 to 0.31

In this problem, we have a graph of the PDF (Probability Density Function). To compute probabilities in a certain interval (a, b), we must integrate this function from x = a to x = b.
(1) P(X ≤ 22)
We integrate the function from x = -∞ to x = 22, we get:
\(\begin{gathered} P(X\text{ }≤\text{ }22)=\int_{-\infty}^{22}dx\cdot PDF(x) \\ =\int_{-\infty}^{20}dx\cdot PDF(x)+\int_{20}^{22}dx\cdot PDF(x) \\ =\int_{-\infty}^{20}dx\cdot0+\int_{20}^{22}dx\cdot0.25 \\ =0+0.25\cdot(22-20) \\ =0.25\cdot2 \\ =0.5. \end{gathered}\)We separated the integral to use the data from the graph.
(2) P(X > 21)
We integrate the function from x = 21 to x = ∞, we get:
\(\begin{gathered} P(X>21)=\int_{21}^{\infty}dx\cdot PDF(x) \\ =\int_{21}^{24}dx\cdot PDF(x)+\int_{24}^{\infty}dx\cdot PDF(x) \\ =\int_{21}^{24}dx\cdot0.25+\int_{24}^{\infty}dx\cdot0 \\ =0.25\cdot(24-21)+0 \\ =0.25\cdot3 \\ =0.75. \end{gathered}\)(3) The Q1 is the value x = a of the interval (-∞, a) that gives a probability equal to 0.25. So we must find x such that:
\(P(XUsing the data of the graph, we have:\(\begin{gathered} \int_{-\infty}^adx\cdot PDF(x)+\int_{20}^adx\cdot PDF(x)=0.25, \\ \int_{-\infty}^{20}dx\cdot0+\int_{20}^adx\cdot0.25=0.25, \\ 0.25\cdot(a-20)=0.25, \\ a-20=\frac{0.25}{0.25}, \\ a-20=1, \\ a=21. \end{gathered}\)(4) The median is the value x = a of the interval (-∞, a) that gives a probability equal to 0.5.

2x^2 + 8x factor out the gcf
Answers
Answer:
2x(x + 4)
Step-by-step explanation:
The greatest common factor of 2x^2 and 8x is 2x. So, we can factor out 2x to get:
2x(x + 4)
The definition of a greatest common factor (GCF) is the largest number that is a factor of two or more numbers. In this case, 2x is the GCF of 2x^2 and 8x because it is the largest number that divides both numbers evenly.
Here are the steps on how to factor out the GCF:
Find the GCF of the two numbers. In this case, the GCF is 2x. Write the GCF as a factor of each number. Combine the factors to get the factored expression.In this case, the factored expression is 2x(x + 4).
The answer is:
⇨ 2x(x + 4)Work/explanation:
Let's find something that \(\sf{2x^2}\) and \(\sf{8x}\) have in common.
In other words, we find their GCF (greatest common factor).
The GCF of \(\sf{2x^2}\) and \(\sf{8x}\) is 2x.
So I factor it out :
\(\sf{2x(x+4)}\)
Hence, the answer is 2x(x + 4).3(3y - 10) = 6 I need the answer please

Answer:
If you wanted to simplify the equation:
9y - 30 = 6
If you wanted to solve for y:
y = 4
Step-by-step explanation:
3(3y - 10) = 6
9y - 30 = 6
Add 30 to both sides of the equation:
9y - 30 + 30 = 6 + 30
Simplify:
9y = 6 + 30
9y = 36
Divide both sides of the equation by 9:
9y ÷ 9 = 36 ÷ 9
Cancel terms that are in both the numerator and denominator:
y = 36 ÷ 9
y = 4
