Answer:
C) $826.82 to $873.18.
Step-by-step explanation:
Sample mean (M) = $850
Standard deviation (s) = $54
sample size (n) = 36
Z for 99% confidence interval (Z) = 2.576
The confidence interval is determined by the following relationship:
![M \pm Z*\frac{s}{\sqrt{n}}](https://tex.z-dn.net/?f=M%20%5Cpm%20Z%2A%5Cfrac%7Bs%7D%7B%5Csqrt%7Bn%7D%7D)
Applying the given values, the lower (L) and upper (U) values are:
![850 \pm 2.576*\frac{54}{\sqrt{36}}\\L=\$826.82\\U=\$873.18](https://tex.z-dn.net/?f=850%20%5Cpm%202.576%2A%5Cfrac%7B54%7D%7B%5Csqrt%7B36%7D%7D%5C%5CL%3D%5C%24826.82%5C%5CU%3D%5C%24873.18)
The answer is C) $826.82 to $873.18.
An=a1+d(n-1)
a1=first term
d=common difference
n=which term
common difference is 5 first term is 2
an=5+2(n-1)
19th term is n=19
a19=5+2(19-1)
a19=5+2(18)
a19=5+36
a19=41
19th term is 41
You have an equation with to variables.

<span>y - 4 = -2/3(x - 9)
3y - 12 = -2x + 18
3y = -2x + 30
y = -2/3 x + 10 <------ slope-intercept form
