Answer:
f=24
Step-by-step explanation:
3 = f/6 - 1
Multiply both sides of the equation by 6.
18=f−6
Swap sides so that all variable terms are on the left hand side.
f−6=18
Add 6 to both sides.
f=18+6
Add 18 and 6 to get 24.
f=24

Answer:
6 samples
Step-by-step explanation:
Given :
Sample size, = n
Standard deviation, = 6000
Margin of Error = 2000
Confidence interval, α = 95%
Zcritical at 95% = 1.96
n = (Zcritical * σ) / margin of error
n = (1.96 * 6000) /2000
n = 11760 / 2000
n = 5.88
n = 6 samples
Answer:
C. 10
