Answer:
A
Step-by-step explanation:
6x- 3x + 6=18
6(4)- 3(4) + 6=18
24-12 + 6=18
12 +6=18
18=18
the square root of 5000 is 71 (rounded to the nearest)
Answer: p = 0.73
Step-by-step explanation:
Given that,
73% of the audience was under 20 years old :
so, probability (p) = 0.73
n = 146
Mean of the distribution of sample proportion = ?
According to central limit theorem,
np(1-p) ≥ 10
146 × 0.73(0.27) ≥ 10
28.77 ≥ 10
∴ Central limit theorem assumes that the sample distribution of the sample proportion is normally distributed.
Hence, the mean of the distribution of sample proportion:
μ = p = 0.73
Answer:
5652
Step-by-step explanation:
Hi there! Let's solve this problem together.
Formula for finding volume in pi: V = pi × radius squared × height
Our height is 18, and our radius is 10. Now, let's calculate.
3.14 x 10 squared (100) = 314.
314 multiplied by 18 is 5,652.
The answer is 5652. I hope this helps you!
