It is A. We have a ratio of
900 workers : 3.2×10⁵
Dividing by 9×10² becomes
1 worker :

×10³
3.2/9 is just 0.36 rounded so it is
1 worker : 0.36×10³
or A
C = 150000 + 17n
where,
C = Total Cost per year = Fixed Cost + Variable Cost
n = Number of Widgets produced each year
17n = Variable Cost
150000 = Fixed Cost
Answer:
A
Step-by-step explanation:
i used the process of elimination and got rid of answers that didnt make sense but based on the info given i could tell that x was 5 months because of where the point of 5 is on the graph
Solution :
Given :
Sample mean, 
Sample size, n = 129
Sample standard deviation, s = 8.2
a. Since the population standard deviation is unknown, therefore, we use the t-distribution.
b. Now for 95% confidence level,
α = 0.05, α/2 = 0.025
From the t tables, T.INV.2T(α, degree of freedom), we find the t value as
t =T.INV.2T(0.05, 128) = 2.34
Taking the positive value of t, we get
Confidence interval is ,


(32.52, 35.8)
95% confidence interval is (32.52, 35.8)
So with
confidence of the population of the mean number of the pounds per person per week is between 32.52 pounds and 35.8 pounds.
c. About
of confidence intervals which contains the true population of mean number of the pounds of the trash that is generated per person per week and about
that doe not contain the true population of mean number of the pounds of trashes generated by per person per week.
