Answer:
(2/x)3 or 3(2/x
Step-by-step explanation:
The quotient of 2 and x is expressed as 2/x Multiplied by 3 can be expressed as (2/x)3 or 3(2/x)
Answer:
The width is 88
Step-by-step explanation:
<u>Perimeter of a rectangle: 2L + 2W</u>
<u />
<u>Step 1: Solve for W</u>
374 = 2(99) + 2W
374 - 198 = 198 + 2W - 198
176 / 2 = 2W / 2
88 = W
Answer: The width is 88
Answer:
Step-by-step explanation:
Given that X, the number of square feet per house is N(mean, 137)
Sample size = 19
Sample mean x bar =1350 sq ft
Since population std dev is given,
std error of sample = 
Since sample size is small, t critical value can be used
df = 18
t value for 80% two tailed = 1.333
Margin of error = ±1.333(std error) = ±
Confidence interval = sample mean ±margin of error
=
