Answer:
b = 18
Step-by-step explanation:
From an external point, the products of distances to the near circle intercept and the far circle intercept are the same. For a tangent, such as AC, point A is both the near and far intercept point, so that product is the square of the length of AC.
(AC)² = (CG)(CV)
b² = 12·27 = 324 . . . . substitute known values
b = √324 . . . . . . . . . . take the square root
b = 18
Answer:
11. your choices are correct
12. 132°
Step-by-step explanation:
11. The given equations can be (re)written to slope-intercept form. Only those lines with a slope of 2 will be parallel to the given line.
A: y = 2x -8 . . . . . slope = 2, an answer
B: y = -2x +1 . . . . . slope = -2, not an answer
C: y = -2x +7 . . . . .slope = -2, not an answer
D: y = 2x +2 . . . . . slope = 2, an answer
E: y = -2x -9 . . . . . slope = -2, not an answer

12. The marked angles are supplementary, so ...
(3x -6)° +(x +2)° = 180°
4x -4 = 180 . . . . . . . . . . . divide by °, collect terms
x -1 = 45 . . . . . . . divide by 4
x = 46 . . . . . . . . . add 1
Now, we can find the angle of interest.
∠PQR = (3x -6)° = (3·46 -6)°
∠PQR = 132°
False , Combining a coin toss and a roll of a die makes a simple event.
In statistics, what does a probability mean?
- The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is.
- P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.
- Mathematics' study of random events is known as probability, and there are four primary types of probability: axiomatic, classical, empirical, and subjective.
- Since probability is the same as possibility, you could say that it is the likelihood that a specific event will occur.
