Answer:
and 
Step-by-step explanation:
The null hypothesis
states that a population parameter (such as the mean, the standard deviation, and so on) is equal to a hypothesized value. We can write the null hypothesis in the form 
In this context, the investigator's null hypothesis should be that the average total weight is no different than the reported value by the FAA. We can write it in this form
.
The alternative hypothesis
states that a population parameter is smaller, greater, or different than the hypothesized value in the null hypothesis. We can write the alternative hypothesis in one of three forms

The investigator wants to know if the average weight of passengers flying on small planes exceeds the FAA guideline of the average total weight of 185 pounds. He should use
as his alternative hypothesis.
Answer: The slope is 2 -Please mark brainliest
1. Find the X and Y values of each point
X1: 1
X2: -1
Y1: 3
Y2: -1
2. Subtract X1 from X2 and Y1 from Y2
Y: -1-3=-4
X: -1-1=-2
3. Divide the X value by the Y value
-4/-2=2
The slope of the line shown on the coordinate plane is 2.

Answer:
The answer is C
Step-by-step explanation:
You are multiplying 10 by a number that is less than 1 to the x power which will cause the number to decrease
