A tennis ball was thrown in the air. The height of the ball from the ground was recorded every millisecond from the time the ball was thrown until it reached the height from which it was thrown. The correlation between the time and height was computed to be 0. What does this correlation suggest about the relationship between the time and height? There is no relationship between time and height.
A

There is no linear relationship between time and height.

There is no linear relationship between time and height.
B

The distance the ball traveled upward is the same as the distance the ball traveled downward.
C

The correlation suggests that there is measurement or calculation error.
D

The correlation suggests that more measurements should be taken to better understand the relationship.
E

A There is no relationship between time and height.

Step-by-step explanation:

Given:  The correlation between the time and height was computed to be 0.

That means, There is no relationship between time and height.

Hence, the correct option is "A".

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
