Answer:
D: (x – 7)2 + (y + 2)2 = 52
Step-by-step explanation:
Circle: (x -h)² + (y - k)² = r² center (h , k) r: radius
(1 , -6) on the circle: radius √(1 - 7)² + (-6 - (-2))² = √36 + 16 = √52
(x -7)² + (y +2)² = (√52)² = 52

Answer:
For a level of 0.0174 or more of nitrogen oxide, the probability of fleet is 0.01.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 0.02 g/mi
Standard Deviation, σ = 0.01 g/mi
Sample size, n = 81
We are given that the distribution of level of nitrogen oxides is a bell shaped distribution that is a normal distribution.
Standard error due to sampling:

Formula:
We have to find the value of x such that the probability is 0.01
P(X > x)
Calculation the value from standard normal z table, we have,
For a level of 0.0174 or more of nitrogen oxide, the probability of fleet is 0.01.
Answer:
y - 2 = 3(x - 2)
Step-by-step explanation:
Hello!
Please consider using the point-slope formula for the equation of a straight line, because in this case it's the easiest way to go.
(2,2) is one point on the line, and the slope is m = -3.
Thus, y - k = m(x - h) becomes y - 2 = 3(x - 2).
