C. 3^9
Explanation: Look at the photo! Hope this helps :)
3^5(3^4)
=(3•3•3•3•3) + (3•3•3•3)
=3^9
*additionally, all other answer choices do not have the same product as 3^9, which is 19,683
Answer:

Answer:
Step-by-step explanation:
Let consider that both pyramid are simmilar. The surface area of the pyramid is directly proportional to the square of the height is:
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
