Answer:
72in
Step-by-step explanation:
If AB = 24 inches and AB is dilated by a scale factor of 3, then A'B' is gotten by multiplying the AB by the sclae factor as shown;
A'B' = 3AB
A'B' = 3(24)
A'B' = 72 in
Hence the length of A'B' is 72in

A car starting from rest accelerates at a rate of 7.5 m/s2. What is its final speed at the end of 4.0 seconds?
Step-by-step explanation:
initial velocity is 0
time is 4 seconds
acceleration is 7.5mper second square
using the formula s=ut+1/2at^2[distance equal to initial velocity times time plus half into acceleration times (time )squared] substitute s=0×4+2×7.5 ×4^2
s=0+7.5×16
s=120m
Factor completely: 2x^3-12x^2+18x
Answer:
2x(x - 3)²
Step-by-step explanation:
We can simplify this a lot by first factoring 2x out of each term:
2x³ - 12x² + 18x
= 2x(x² - 6 + 9)
We can then factor the trinomial fairly easily, as it's a perfect square:
= 2x(x - 3)²

1 rabbit = 2 cats
2 rabbits = 4 cats
3 rabbits = 6 cats
2 cats = 5 dogs
4 cats = 10 dogs
6 cats = 15 dogs

The mean number of minutes spent on a
treadmill at the local gym is 28 minutes with a
standard deviation of 8. If Kurt's z-score is
1.75, how much time did he spent on the
treadmill?
Answer:
With a z score of 1.75, mean of 28 and standard deviation of 8
1.75=(Xi-28)/8
14=(Xi-28)
42 = Xi
Kurt was on the treadmill for 42 minutes

A sports equipment researcher investigated how different types of wood used to make baseball bats might affect batting. The researcher selected a sample of 80 batters from summer baseball leagues and randomly assigned the batters to one of two groups: the ash bat group or the maple bat group. The mean number of hits for each group was recorded at the end of the season, and the difference in the sample means was calculated. Which of the following is the appropriate inference procedure for analyzing the results of the investigation?
A. A one-sample t-interval for a population mean
B. A one-sample t-interval for a sample mean
C. A matched pairs t-interval for a mean difference
D. A two-sample t-interval for a difference between sample means
E. A two-sample t-interval for a difference between population means
Answer:
E
A two-sample t -interval for a difference between population means
Step-by-step explanation:
i just took the test
The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means
Analysis the results of the investigation:Since the researcher selected a sample of 80 batters from summer baseball leagues and batters assigned to one of the two groups. So this means that the researcher is interested to know whether the mean no of hits should be different for two groups and both groups are independent to each other.
Therefore, The appropriate inference procedure for analyzing the results of the investigation is option E. A two-sample t-interval for a difference between population means

How far up the house would a ladder be resting if it is 25 ft long and 3 ft
away from the house? Round to the nearest tenth if necessary.
5.3 ft
21 ft
24.8 ft
25.2 ft
Answer:
C
Step-by-step explanation:
The last one is absurd. You can't have a ladder reaching higher than itself. The question is a Pythagorean problem.
Givens
a = 3
b = ?
c = 25 feet
Formula
a^2 + b^2 = c^2
Solution
3^2 + b^2 = 25^2
9 + b^2 = 625 Subtract 9 from both sides.
b^2 = 625 - 9
b^2 = 616 Take the square root of both sides.
b = sqrt(616)
b = 24.8
what is this equal to

From the set {24, 36, 72}, use substitution to determine which value of x makes the inequality true.
x ÷ 12 < 3
Answer:
24
Step-by-step explanation:
Given the inequality : x ÷ 12 < 3
Substitute the values in the set for X and test the inequality expression if it hoods true for each of the substituted value.
x = 24
24 ÷ 12 < 3
2 < 3 (true)
x = 36
36 ÷ 12 < 3
3 < 3 (false)
x = 72
72 ÷ 12 < 3
