Multiply principle by time by rate
1200(.02)(5)
120
Answer: 38 in.^{2}
Step-by-step explanation:
1/ Find the area of the triangular sides. (1/2 x 2 x 6 = 
for each triangular side)
2/ Find the area of each of the rectangular sides. In this case, the bottom (base) side is 2x6 = 
. The rectangular side on the left is 2x3 = , and the rectangular side on the right is 4x2 = 
.
3/ Add everything together. Rectangular Sides + Triangular Sides = Surface Area ---> 
4/ You have your answer, now hope it helps ! :)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Sample mean(x) = 23500
Sample standard deviation (sd) = 3900
Sample size (n) = 20
Population mean (m) = 20,000
Null hypothesis : m = 20000
H1: m > 20000
To obtain the z-score :
(population mean - sample mean) / (sample standard deviation /√sample size)
(x - m) / (sd/√n)
(23500 - 20000) / (3900 / √20)
3500 / (3900 /4.4721359)
3500 / 872.06651
= 4.0134
Get the P value to know if to reject or accept the null:
P(z > 4.0134) = 1 - P(z < 4.0134)
P(z < 4.0134) = 1
1 - P(z < 4.0134) = 1 - 1 =0
Since P value is < alpha, we reject the null.
Hence average is > 20000
This is the answer to your problem
