Answer:
<em>( x + 4 )^2 + ( y - 15 )^2 = 1; Option A</em>
Step-by-step explanation:
<em>~ Let us apply the standard circle equation ( x - a )^2 + ( y - b )^2 = r^2, provided r ⇒ radius when centered at point ( a, b ) ~</em>
1. If the center is provided to be ( -4, 15 ) we could substitute this value into the circle equation with variables x and y remaining such:
( x - ( - 4 ) )^2 + ( y - 15)^2 = r^2
2. Simplifying this equation, we have: ( x + 4)^2 + ( y - 15 )^2 = r^2
3. Now by point on the circle, it would be a point on the circumference, to be clear in more mathematical terms. So far we have eliminated two options, with two remain - and each of them has either a radius of 1 or 2. If the point on the circle is ( -4, 16 ) that would mean 1 more than 15, which means that with a radius of 1 ⇒ this point will be on the circle.
<em>Answer: ( x + 4 )^2 + ( y - 15 )^2 = 1</em>

Answer:
The value is 0.025
Step-by-step explanation:
We get the z-score that is equal to the given value
Mathematically we have this as:
z-score = (x-mean)/SD
x = 93
mean =79
SD = 7
So we have the z-score as;
z-score = (93-79)/7 = 14/7 = 2
So we want to calculate the probability equal to the calculated z-score value of 2
Using the standard normal distribution table, we have this value as;
1 - 0.975= 0.025
