So if the height is going to be 20ft, that means 20 = 2+35t-16t²
Answer:
34
Step-by-step explanation:
32 / 8 = 4
36 / 4 = 9
perimeter of rectangle = 2(Length) + 2(width)
P = 2(8) + 2(9)
P = 16 + 18
P = 34
Answer:
Surface area≈ 179.38 m
Step-by-step explanation:
Right rectangular pyramid: length×width×height
= 8 m× 8 m× 6 m
≈179.38 m
Given:
n = 150, sample size
Denote the sample proportion by q (normally written as

).
That is,
q = 60/150 = 0.4, sample proportion.
At the 96% confidence level, the z* multiplier is about 2.082, and the confidence interval for the population proportion is
![q \pm z^{*}[ \frac{q(1-q)}{ \sqrt{n} } ]](https://tex.z-dn.net/?f=q%20%5Cpm%20z%5E%7B%2A%7D%5B%20%5Cfrac%7Bq%281-q%29%7D%7B%20%5Csqrt%7Bn%7D%20%7D%20%5D)
That is,
0.4 +/- 2.082* √[(0.4*0.6)/150]
= 0.4 +/- 0.0833
= (0.3167, 0.4833)
= (31.7%, 48.3%)
Answer: The 96% confidence interval is about (32% to 48%)
