Answer:
B. (x - 2)^2 + (y - 1)^2 = 9.
Step-by-step explanation:
The general equation for a circle can be written as:
(x - a)^2 + (y - b)^2 = r^2 where the centre is at (a, b) and the radius= r.
Here a = 2, b = 1 and r = 3 so the answer is:
(x - 2)^2 + (y - 1)^2 = 3^2
= (x - 2)^2 + (y - 1)^2 = 9.
Answer:
x = 15°
Step-by-step explanation:
Linear pair = 180°
⇒ (6x - 5) + (6x + 5) = 180°
⇒ 12x = 180°
⇒ x = 15°

Convert a z statistic to a t statistic
Answer:
x = 8.8 or x = 44/5
Step-by-step explanation:
1) Multiply both sides of the equation by 4, and cancel out the 4 on the bottom of 3/4, this turns the equation into: 8x - 4 = 3x + 40
2) Move the x to the lefthand side and change the side, do the same for the constant (4), this turns the equation into: 8x - 3x = 40 + 4
3) Combine like terms, subtract 8x from 3x and add 40 to 4: 5x = 44
4) Divide both sides by 5, and your answer is 44/5 (or 8.8 when converted to a decimal)
