The answer is A) 3.
I hope this helps.
A quadratic function would fit this data.
The data does not increase at the same rate each time, so it is not linear. It comes to a maximum at (8, 150) and decreases. It decreases the same way it increased. This would lead to a U-shaped graph, which indicates a quadratic function.
Answer:
Around 4800 cubic centimeters.

Answer:
b. 98
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
So a sample of at least 98 is required.
The correct answer is:
b. 98
U have a dashed line.....it has a y int of 2...it has slope of 1/3....it is shaded below the line....this inequality is : y < 1/3x + 2
u have a solid line...it has a y int of 2...it has a slope of -2...it is shaded below the line...this inequality is : y < = -2x + 2
