You’re gonna figure out the area of each side first. I’d recommend labeling them by letter to help keep track. Do 8x5=40 then multiply 40 by 2 (because there are two sides that are 8x5) then do 3x4 which is 12 usually you would divide 12 by 2 to get the area of a triangle but in this case just leave it alone because there are two triangles. Then do 3x8 for the rectangle (24) then you’re gonna add all the sides together. So 40+40+12(or 6+6) +24...youre answer should me 116

Answer:
Step-by-step explanation:
We want to determine a 95% confidence interval for the population mean for the prices of slice toasters.
Number of sample, n = 12
Mean, u = $61.12
Standard deviation, s = $24.62
For a confidence level of 95%, the corresponding z value is 1.96.
We will apply the formula
Confidence interval
= mean ± z ×standard deviation/√n
It becomes
61.12 ± 1.96 × 24.62/√12
= 61.12 ± 1.96 × 7.107
= 61.12 ± 13.93
The lower end of the confidence interval is 61.12 - 13.93 =47.19
The upper end of the confidence interval is 61.12 + 13.93 = 75.05
