Answer:
Step-by-step explanation:
formula for cylinder:V=πr2h
shape of the base: circle
formula for circle: A=πr2
radius: 6.5cm
height: 16cm
V=3.14x6.5^2x16
2122.64cm^3
A). I would start at $100 through $200. since the range doesn't start until $110 there is no reason to show the numbers 0-90.
b). I would then go up by 10 on each interval. going up by 10 can easily be graphed and accurate.
The answer will be Mean = 135 Variance = 62 and Standard Deviation = 8
<h3>What is the standard deviation? </h3>
Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
Given that :
Proportion (p) = 54%
Sample size (n) = 250
Using Normal approximation :
Mean = np
Mean = 250 * 0.54 = 135
Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46
Variance = (250 * 0.54 * 0.46) = 62.1 = 62
Standard deviation = √variance = √62.1
Standard deviation = 7.8803553 = 8

We know that:
perimeter = (2 x width) + (2 x length)
Plugging in what we know to this equation:
40 = (2 x 8) + (2 x length)
40 = 16 <span>+ (2 x length)
</span>24 = <span>2 x length
</span>12 = length
The length of the room is 12 feet
