Answer:
$5367.54
Step-by-step explanation:
9000 = P(1 + .03/12)^207*
9000 = P×1.676744643
P = 5367.54
*207 = 12 x 17.25
Anwser would be 18/14 simplified to 9/7
Answer:
107mm²
Step-by-step explanation:
The whole square:
9mm × 15mm = 135mm²
The white area:
7mm × 4mm = 28mm²
Now subtract the white area from the whole square:
135mm² - 28mm² = 107mm²
Shaded Area: 107mm²
Answer:
The size of the sample = 1088.90
Step-by-step explanation:
Given that:
The confidence interval level = 0.95
The margin of error = 0.03
Suppose the proportion of the boys and the girls are p₁ and p₂ respectively.
The Standard error S.E of difference is:
Assume p₁ = p₂ = 0.5
The z-critical value at 95% C.I = 1.96
Margin of error = Z_{critical} × S.E
∴
n ≅ 1088.90
