When plugging this into the calculator, you find:

The answer would be 8.9.
The ordered pairs below represent a relation between x and y.(-3,1), (-2,3), (-1,5), (0,7), (1,9), (2,11)Could this set of order

Yes because its like x cant cheat on y but y can cheat on x so basically your answer is yes and if you need anything else let me know
Answer:
34 ft. tall
Step-by-step explanation:
Your first step should to draw a diagram. When you do that, your diagram should look like a right triangle, the leg, or the distance from the firetruck to the building, (we'll call this a) should be 30ft. and the hypotenuse, or the ladder (we'll call this c), should be 45ft.
Now we have a visual so it'll be easier.
We know that this problem is a right triangle and we know that to solve for a missing side of a right triangle you use pythagorean theorem: a^2+b^2=c^2
We know one leg 'a' and the hyp. 'c' and we just need to find 'b' the other leg (aka the building):
Plug in numbers and simplify:
30^2+b^2=45^2
900+b^2=2025
b^2=1125
≈33.54 OR 34 ft. tall

Answer: 23.9
Step-by-step explanation:
1. First, you must calculate the mean, as following:

2. Now, you should substract the means obtained to every single number of the set and then square it. Add all of them:

3. The mean of this is:

4. The square root of this result is:

5. To the nearest tenth, the result is: 23.9
