Answer:
A 4% increase per annum increases the population by a multiple of 1.04.
population after 10 years = initial population × 1.04^(years)
=2200×1.04^(10)= 3256.54 or 3257 rounded up
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

The y-intercept is the y value when x = 0, or (0 , y)
Based on the graph, your y-intercept is at (0 , 2) or 2
The slope(m) can be found using the slope formula and plugging in 2 points:
But if you look at the answer choices, if the slope is positive, the line would be going up and to the right
If the slope is negative, the line would be going down and to the right
your answer is A
