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

Answer:
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

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.

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
where, l be the length
b be the width
h be the height
Now,
Putting, l=6, b=3 and h=12 we get,
sq m
or, 
sq m
Hence,
The surface area of the prism is 252 sq m.
