Use the Pythagorean theorem:
The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building.
Use Pythagaras theorem :-
x^2 = 1.8^2 + 2.4^2 where a is distance required
x^2 = 9
x = 3 miles Answer
1: B $3.85
2: C The rabbit; 14 miles per hour
3: C 2 1/2 miles
1. Reason: To find the price per gallon, all you need to do is divide 46.20 by 12 to get 3.85
2. Reason: To find which animal is faster all you have to do is subtract the greater number, which is the rabbit that travels 35 miles per hour from the smaller number which is the fox that travels 21 miles.
Subtract: 35-21= 14. So the rabbit is faster by 14 miles.
3. Reason: If Randy walks 1/2 mile in every 1/5 hour, to find the much he will walk in a hour you could count up:
1/2 mile = 1/5 hour
1 mile = 2/5 hour
1 1/2 mile = 3/5 hour
2 mile = 4/5 hour
2 1/2 mile = 1 hour
So, Randy will travel 2 1/2 miles in a hour.
The answers to the questions are:
1. The confidence level is 99 percent.
2. We have to conclude that there is no sufficient evidence available to support this claim because the Confidence interval contains 75 sec.
<h3>How to solve for the confidence level</h3>
1. The confidence level here should be
1- 0.01 = 0.99
= 99 percent
Given that, 99% confidence interval for population mean (μ) is (-34.1 sec u< u < 264.1 ) seconds.
We are to test the claim that the population mean is greater than 75 sec.
2.
The given confidence interval contains the value of 75 sec, so there is not sufficient evidence to support the claim that the mean is greater than 75 sec.

Answer:
-8 and -7
Step-by-step explanation:
First, let's find the cubed version of each answer choice.
-12 and -11:
- -12 cubed = -1728
- -11 cubed = -1331
-20 and -19:
- -20 cubed = -8000
- -19 cubed = -6859
-15 and -14:
- -15 cubed = -3375
- -14 cubed = -2744
-8 and -7:
- -8 cubed = -512
- -7 cubed = -343
Therefore, the answer is -8 and -7.
