The point halfway between two end points is called a midpoint
Answer:
N is a population parameter; the computation using an estimate of N is a statistic.
Step-by-step explanation:
A parameter is a measure of a population. The number of warplanes fielded total is N; this makes it the population. Thus N is a parameter.
A statistics is a measure of a sample. The number computed using an estimate of N would be based on a sample, since it is an estimate of N; this makes it a statistic.
The top-left graph goes with the bottom-right equation, y=90(1/4)^x
The bottom-left graph goes with the top-right equation, y = 120(3/4)^x
The top-right graph goes with the bottom-left equation, y = 120(1/4)^x
The bottom-right graph goes with the top-left equation, y = 90(3/4)^x
y=90(1/4)^x has a larger percent decrease than y = 90(3/4)^x
cause if you multiply a number by 1/4, that's smaller than multiplying number by 3/4. so y=90(1/4)^x decreases really fast
same with the y = 120(3/4)^x ones
