Answer:
153.158 ; 177.642
Step-by-step explanation:
Given the following:
Sample mean (m) = 165.40
Sample standard deviation (s) = 21.70
Sample size (n) = 17
α = 98%
Confidence interval = m ± z(SE)
z at 98% = 2.326
SE = s/√n
SE = 21.70/√17 = 5.2630230
Hence,
Confidence interval = 165.40 ± 2.326(5.2630230)
165.40 - 12.241791498 OR 165.40 + 12.241791498
153.158 ; 177.642

Answer:
4 ft by 12 ft
Step-by-step explanation:
x^2 +8x -48
Set this equal to 0 to solve for the values of x
x^2 +8x -48=0
What two values multiply to -48 and add to 8
12*-4 = -48
12+-4 = 8
(x+12) (x-4) = 0
Using the zero product property
x+12 = 0 x-4=0
x=-12 x=4
We cant have a negative length
x=4
The area is 48
48/4 = 12
The other dimension is 12
Gross income= $813.61
Step-by-step explanation:
Giving the following information:
Sales= $32,874
Fixed salary= $452
Commission= 1.1% paid on sales in excess of $25,000.
To calculate the gross income, we need to use the following formula:
Gross income= 452 + y*x
y= percentage comission
x= sales
For $32,874 sales:
Gross income= 452 + 0.011*32,874
Gross income= $813.61
