Answer:
(x - 2)² + (y + 3)² = 9
Step-by-step explanation:
(x - h)² + (y - k)² = r²
(x - 2)² + (y - (-3))² = 3²
(x - 2)² + (y + 3)² = 9

Answer:
RQ = 49
Step-by-step explanation:
12/28 = 21/RQ (Ratio of sides of similar triangles are equal)
12 x RQ = 21 x 28
RQ = 588 / 12
RQ = 49
22 - 5(6v - 1) = -63 First, you distribute 5 to the parentheses.
22 - 30v + 5 = -63
27 - 30v = -63
-30v = -90
v = 3

Determine the Mean and Variance
Equally likely implies that the data follows a uniform distribution.
So,

Where






Variance of a uniform distribution is calculated as thus;

Substitute values for a and b
