Answer:
She should aim 6 feet down the wall
Explanation:
The diagram attached sketches the situtation.
Since the angle with which the ball hits the wall is the same with which it bounces, angle β is the same for the two shown triangles.
Then, since both are right triangles, then all the angles are congruent and the triangles are similar. Hence, you can equal the ratios of the sides, to make an equation:
x/4 = y/2 ⇒ x = 2y
You have other equation:
x+ y = 18
Substitute
2y + y = 18
3y = 18
y = 18/3
y = 6 ← this is the distance down the wall where the ball should hit
x = 2(6) = 12
Then, she should aim 6 feet down the wall.
Answer:
148-13=135
4x+13= - 3.25
6x+2 = - 0.33
Step-by-step explanation:
1) SIMPLE SUBTRACTION
148
- 13
---------
135
---------
2)
4x+13=0
4x= - 13
x= -13/4
x= - 3.25
3)
6x+2 = 0
6x= -2
x= -2/6
x = -0.33
First you find the median which is 4. The mean is calculated by the sum of the distribution divided by the amount of numbers in the distribution (20). The mean comes out to be 4.35. Subtract 4.35 from 4 and your answer is .35.
