Answer:

a) The interval for those who want to go out earlier is between 43.008 and 46.592

b) The interval for those who want to go out later is between 47.9232 and 51.9168

Step-by-step explanation:

Given that:

Sample size (n) =128,

Margin of error (e) = ±4% =

a) The probability of those who wanted to get out earlier (p) = 35% = 0.35

The mean of the distribution (μ) = np = 128 * 0.35 = 44.8

The margin of error = ± 4% of 448 = 0.04 × 44.8 =  ± 1.792

The interval = μ ± e = 44.8 ± 1.792 = (43.008, 46.592)

b) The probability of those who wanted to start school get out later (p) = 39% = 0.39

The mean of the distribution (μ) = np = 128 * 0.39 = 49.92

The margin of error = ± 4% of 448 = 0.04 × 49.92 =  ± 1.9968

The interval = μ ± e = 44.8 ± 1.792 = (47.9232, 51.9168)

The way for those who want to go out earlier to win if the vote is counted is if those who do not have any opinion vote that they want to go earlier

The formula for a quadrilateral depends on the shape.

Area of a Parallelogram: Base × Height

Area of a Rectangle: Length × Breadth

Area of a Square: (side)^2

Area of a Kite: (1 ⁄ 2) × Product of Diagonals

Area of a Trapezoid: (base1+base2/2) x Height

I hope this helps :)

When Jerome travels on the highway, he sets his cruise control at 65 mi/h. The function f(x)=65x represents his total distance f
OLga [1]

The number of miles that he will have traveled after 3.5 hours of driving on the highway is 227.5 miles.

The function given to solve the question is: f(x) = 65x

where, x = number of hours

Therefore, when he travelled for 3.5 hours, the number of miles will be gotten by multiplying 65 by 3.5.

f(x) = 65x

= 65 × 3.5

= 227.5 miles.

Therefore, the number of miles that he will have travelled after 3.5 hours of driving on the highway is 227.5 miles.

Find the surface area of the prism. Enter your answer in the box.
Snowcat [4.5K]

Given:

The length of the given prism = 6 m

The width of the given prism = 3 m

The height of the given prism = 12 m

To find the surface area of the prism.

Formula:

The surface area of the prism is

A = 2(lb+bh+hl)

where, l be the length

b be the width

h be the height

Now,

Putting, l=6, b=3 and h=12 we get,

A= 2((6)(3)+(3)(12)+(12)(6)) sq m

or, A =252 sq m

Hence,

The surface area of the prism is 252 sq m.
