You wish to estimate a population proportion with a confidence interval with a margin of error no larger than 0.03. You have a b

NikAS [45]

Answer:

The answer is 0.8788

Step-by-step explanation:

From question given, let us recall the following:

We know that Ƶα /2 * √p (1-p)/n

when we use n≤ 5000/10 =500

P = 0.75

The Margin of error = 0.03

Putting this values together we arrive at

Ƶα/2 = 0.03/√0.75 * 0.25/500

= 1.549

Now,

Ф (1.549) = 0.9394

Therefore the confidence level becomes:

1- (1-∝)/2 = 0.9394

∝ = 0.8788

The answer is 0.8788

You are putting a rectangular hot tub on your back porch. It is 6 feet long, 5 feet wide, and 3 feet deep. How much will it cost

igor_vitrenko [27]

Answer:

$Cost=\$3.66234\approx \$3.67$

Step-by-step explanation:

$Height\ of\ tub=3\ feet\\\\Length\ of\ tub=6\ feet\\\\width\ of\ tub=5\ feet\\\\Volume=Length\times Width\times Height\\\\Volume=6\times 5\times 3=90\ feet^3$

$1\ feet^3=7.48052\ gallons\\\\90\ feet^3=90\times 7.48052=673.2468\ gallons$

$cost\ of\ 1000\ gallons=\$5\\\\cost\ of\ 1\ gallons=\$ \frac{5}{1000}\\\\cost\ of\ 673.2468\ gallons=\$ \frac{5}{1000}\times 673.2468=\$3.366234$

Right the slope intercept form for the line that travels through (4,-1) and is parallel to y=1/4x

ololo11 [35]

Answer:

Step-by-step explanation:

The slope is given to you by the line y = 1/4 x

The slope is just read as the number in front of x providing that the coefficient of y is 1. If that is not so, then you must divide by the coefficient in front of y. So far what you have is y = 1/4 x + b.

The second part of the question is to use the given point to find b.

x = 4

y = -1

b = ? substitute x and y to find b

y = 1/4 * 4 + b

- 1 = 1/4 * 4 + b

-1 = 1 + b

-2 = b

The equation of the line is y = 1/4 x - 2 Just to confirm this, I'm going to include the graph with the point 4,-1 on it.
