Rotation through 90° counterclockwise has the mapping.

(x \: ,\: y)  \:  \rightarrow( - y \: ,\:  \: x)
A(2 \:  \:,5) \:  \rightarrow \: A' ( - 5 \:  \:,2)

B(2 \:  , 2) \:  \rightarrow B'( - 2 \: , \: 2)

C(4 ,\:  \: 3) \:  \rightarrow C'( - 3, \:  \: 4)

D(4 ,\:  \: 6) \:  \rightarrow D' ( - 6, \:  \: 4)

According to a poll, 55 % of Americans do not know that GOP stands for Grand Old Party (Time, October 17, 2011). Assume that thi
Ivenika [448]

Answer:

\hat p  \sim N (p , \sqrt{\frac{p(1-p)}{n}})

The mean is given by:

\mu_{\hat p} = 0.55

And the deviation:

\sigma_{\hat p} =\sqrt{\frac{0.55*(1-0.55)}{953}}= 0.0161

Step-by-step explanation:

For this case we assume that the true population proportion of Americans do not know that GOP stands for Grand Old Party is 0.55 and we select a random sample of n = 953 americans

For this case we assume that we satisfy the conditions to use the normal approximation for \hat p

1) np >10 , n(1-p)>10

2) Independence

3) Random sample

4) The sample size is less than 10% of the population size

We assume that all the conditions are satisfied and the distribution for \hat p would be:

\hat p  \sim N (p , \sqrt{\frac{p(1-p)}{n}})

The mean is given by:

\mu_{\hat p} = 0.55

And the deviation:

\sigma_{\hat p} =\sqrt{\frac{0.55*(1-0.55)}{953}}= 0.0161

Terrific Tents has a new two-person tent. If the material costs $0.02 per square inch, find out how much it costs to make each t
AveGali [126]

Answer:

$280

Step-by-step explanation:

Please find attached the image of the tent

cost of the tent = cost per square inch x total surface area of a triangular prism

total surface area of a triangular prism = (perimeter x height) + 2(area of a triangle)

Area of a triangle = 1/2 x base x height = 1/2 x 40 x 50 = 1000in²

1000 x 2 = 2000

Perimeter = 50 + 50 + 50 = 150

150 x 80 = 12,000

total surface area = 12,000 + 2000 = 14,000

Total cost = 14,000 x 0.02 = $280
