Triangle XYZ is similar to triangle JKL. Triangle XYZ with side XY labeled 8.7, side YZ labeled 7.8, and side ZX labeled 8.2 and triangle JKL with side JK labeled 13.05. Determine the length of side LJ. 6.83 11.70 12.30 12.41
Answers
The length of side LJ is 12.41.
Since triangle XYZ is similar to triangle JKL, we know that the corresponding sides are proportional. This means that the ratio of the lengths of the sides in triangle XYZ to the corresponding sides in triangle JKL is constant. We can use this fact to solve for the length of side LJ.
Let k be the constant of proportionality. Then we have:
XY / JK = YZ / KL = ZX / LJ = k
Substituting the given values, we have:
8.7 / 13.05 = 7.8 / KL = 8.2 / LJ
Solving for KL and LJ, we get:
KL = (7.8 x 13.05) / 8.7 = 11.70
LJ = (8.2 x 13.05) / 7.8 = 12.41

A robot moves in the positive direction along a straight line so that
after t minutes its distance is s=6t^(4) feet from the origin. (a) Find
the average velocity of the robot over the interval 2,4. (b) Find the
instantaneous velocity at t=2.
Answers
The robot moves in the positive direction along a straight line so that after t minutes its distance is s=6t^4 feet from the origin. (a) Find the average velocity of the robot over intervals 2, 4. We have the following data: Initial time, t₁ = 2 min.
Final time, t₂ = 4 min.The distance from the origin is given by s = 6t^4Therefore, s₁ = s(2) = 6(2^4) = 6(16) = 96 feet s₂ = s(4) = 6(4^4) = 6(256) = 1536 feet
We can find the average velocity of the robot over the interval 2, 4 as follows: Average velocity = (s₂ - s₁) / (t₂ - t₁)Average velocity = (1536 - 96) / (4 - 2)Average velocity = 1440 / 2Average velocity = 720 feet per minute(b) Find the instantaneous velocity at t=2.To find the instantaneous velocity at t = 2 min, we need to take the derivative of the distance function with respect to time. We have the distance function as:s = 6t^4 Taking derivative of s with respect to t gives the velocity function:v = ds / dt Therefore,v = 24t³At t = 2, the instantaneous velocity is:v(2) = 24(2)³v(2) = 24(8)v(2) = 192 feet per minute Therefore, the instantaneous velocity at t = 2 min is 192 feet per minute.

Answers
The equation that could be used to find how many gallons Erin would need to drive 92 miles is 92 = 23g (option c)
How many gallons is needed to drive 92 miles?
The first step is to determine the gallons needed to drive 1 mile. To do this, divide the 6 gallons by 138 miles. Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷.
Gallons needed for 1 mile = 6/138
In order to determine the gallons needed for 92 miles, multiply the ratio gotten in the previous step by 92
(6/138) x 92 = 4 gallons
The option that gives 4 gallons is : 92 = 23g

5 y = 5-5 0 (5, 0)
-2 y = -2-5 -7 (-2, -7)
The graph of the line y = x-5 is attached below.
Step-by-step explanation:
Given the function
y = x-5
substitute x = 6 in the function
y = 6-5 = 1
so
y = 1
(x, y) = (6, 1)
substitute x = 0 in the function
y = x-5
y = 0-5 = -5
so
y = -5
(x, y) = (0, -5)
substitute x = 5 in the function
y = x-5
y = 5-5 = 0
so
y = 0
(x, y) = (5, 0)
substitute x = -2 in the function
y = x-5
y = -2-5 = -7
so
y = -7
(x, y) = (-2, -7)
Hence, the table becomes
x y = x-5 y (x, y)
6 y = 6-5 1 (6, 1)
0 y = 0-5 -5 (0, -5)

What is the probability that neither A nor B takes place? (Round your answer to 2 decimal places.) Probability
Answers
a. A and B are not independent events because P(A | B) ≠ P(A).
b. A and B are not mutually exclusive events because P(A ∩ B) ≠ 0.
c. The probability value that neither A nor B takes place is 2%.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
a.
To check if two events are independent, we need to check if the occurrence of one event affects the probability of the other event.
We can use the formula P(A | B) = P(A ∩ B) / P(B) to check for independence.
If P(A | B) = P(A), then A and B are independent.
However, in this case, P(A | B) ≠ P(A), which means that the occurrence of B affects the probability of A, so A and B are not independent.
b.
To check if two events are mutually exclusive, we need to check if they can occur at the same time.
If P(A ∩ B) = 0, then A and B are mutually exclusive.
However, in this case, P(A ∩ B) ≠ 0, which means that A and B can occur at the same time, so they are not mutually exclusive.
c. The probability that neither A nor B takes place can be found using the formula P(A' ∩ B') = 1 - P(A ∪ B), where A' and B' denote the complements of A and B, respectively.
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
= 0.59 + 0.54 - 0.15
= 0.98
P(A' ∩ B') = 1 - P(A ∪ B)
= 1 - 0.98
= 0.02
Therefore, the probability that neither A nor B takes place is 0.02 or 2%. This means that both A and B do not occur.

A point estimate is the value of a statistic that estimates the value of a parameter. Question 2 is false and question 3 is true.
Question 1: A point estimate is the value of a statistic that estimates the value of a parameter.A point estimate is a single number that is used to estimate the value of an unknown parameter of a population, such as a population mean or proportion
Question 2: False
Mu (μ) is not used to estimate X. Mu represents the population mean, while X represents the sample mean. The sample mean, X, is used as an estimate of the population mean, μ.
Question 3: True
Beta (β) is indeed used to estimate the population proportion (p) when conducting hypothesis testing on a sample. Beta represents the probability of making a Type II error, which occurs when we fail to reject a null hypothesis that is actually false. By calculating the probability of a Type II error, we indirectly estimate the population proportion, p, under certain conditions and assumptions.

In the NBA in 2003, Yao Ming was one of the tallest players at 7'5" (7 feet 5 inches). Earl Boykins was the shortest player at 5'5". How many inches taller than Boykins was Ming?
Answers
Yao Ming was 24 inches taller than Earl Boykins, as 7 feet is equal to 84 inches and 5 feet 5 inches is equal to 65 inches. Therefore, 84 - 65 = 19 inches, and Ming was 19 inches taller than Boykins.
Yao Ming, standing at 7'5" (7 feet 5 inches), was significantly taller than Earl Boykins, who was 5'5" (5 feet 5 inches) tall in the NBA in 2003. To calculate the difference in height, first convert their heights to inches: Yao Ming = (7 * 12) + 5 = 89 inches and Earl Boykins = (5 * 12) + 5 = 65 inches. Now subtract Boykins' height from Ming's: 89 - 65 = 24 inches. Yao Ming was 24 inches taller than Earl Boykins.

Write a linear equation given the two points: (-3, -9) and (4, -2)
Answers
y = mx + b
where m is the slope of the line, and b is the y-intercept.
To find the slope, we can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are any two points on the line.
Using the given points (-3, -9) and (4, -2), we can calculate the slope:
m = (-2 - (-9)) / (4 - (-3)) = 7/7 = 1
Now that we have the slope, we can use one of the given points to find the y-intercept. Let's use the point (-3, -9):
y = mx + b
-9 = 1*(-3) + b
-9 = -3 + b
b = -6
Therefore, the equation of the line that passes through the points (-3, -9) and (4, -2) is:
