Answer:
It is a state of decay.
Step-by-step explanation:
Graph to figure out of it is growth or decay. If it is increasing than it is growth, if it is decreasing it is decay.
Graph:
0 16
1 9
2 2
3
4
As i said before put the center instead of (h,k) in the general formula and put r=1
so (x-(-2))^2 + (y-(-5)^2 = 1
(x+2)^2 + (y+5)^2 = 1
6,500 is the answer to that question
33.75 is the total because of you having 19 plus 14.75
Standard deviation= σ= 0.1
Confidence interval= 95%= 0.95
Significance level=α= 1-0.95= 0.05
α/2 = 0.025
At α/2 z( α/2 ) =1.960 [from statistic table]
Now,
the sample size at error of 0.02 is
0.02=z( α/2 )σ/√n
0.02=(1.960)*(0.1)/√n
5/49 = 1/√n
√n=49/5
n=96.04
n should be 96 or greater
