Answer:
Step-by-step explanation:
<u>Total number of outcomes:</u>
<u>Number of combinations of getting 6 heads:</u>
- 15C6 = 15!/6!(15-6)! = 5005
<u>Required probability is:</u>
- P(6 heads out of 15 flips) = 5005/32768 = 0.1527... ≈ 15.3%
Correct choice is D
Answer:
The equation is 
Step-by-step explanation:
First off, we know r is going to be subtracted from 6 somewhere in the expression since the problem says "decreasing by r miles per hour."
If we want to see how long it would take him to jog 8 miles up to the mountain road we would have to take 8 and divide it by 6 - r.
Therefore, the equation is

Given:
The triangle ABC rotated 270 degrees clockwise.
The rule of rotation is

To find:
The coordinates of point B after the given rotation.
Solution:
From the given graph, it is clear that the coordinates of point B are (4,4).
The given rule of rotation is:

Using this rule, we get

The coordinates of point B after the given rotation are (-4,4).
Therefore, the correct option is C.
