Answer:
The 25,000 adult American pine trees in the forest.
Step-by-step explanation:
Consider the provided information.
It is given that the forest contains 25,000 adult American pines. The study involves collecting heights from 250 randomly selected adult American pine trees and analyzing the results.
A population is the set of data which includes all of the elements. If one or more observations are drawn form the population then it called a sample.
Here the population is 25,000 adult American pines.
Thus, the required answer is: The 25,000 adult American pine trees in the forest.
The slope is 1. The line first crosses the y axis at -5. So the answer is...
y = 1x + -5
b = -0.5
4 + 2 = - 0.5 * 4 + 8
6 = -2 + 8
6 = 6
Which is true, Therefore the answer is -0.5
Answer:
Roman
Step-by-step explanation:
An easy way to solve this is looking at whether the line has a positive or negative slope. We read graphs from left to right so <u>if the line is increasing from left to right, it has a positive slope while a line decreasing from left to right has a negative slope</u>. Since the line shown is decreasing from left to right, it will have a negative slope and Roman is the only one out of the two that shows a negative slope. To check to see if he's correct, we can check the y-intercept. The y-intercept of the line is 8 and Roman also has 8 written in the expression. Hence, meaning Roman is correct.
Best of Luck!
Answer: 5a + 5b + 5 - x(a + b)
Step-by-step explanation:
(a + b + 1)2 – (a + b + 1)(x - 2) + (a + b + 1)
2a + 2b + 2 - (ax - 2a + bx -2b -2) + (a + b + 1)
2a + 2b + 2 - ax + 2a - bx +2b +2 + a + b + 1
5a + 5b + 5 - x(a + b)
