(a) A golf instructor examined student data. He found that when a student takes longer to hit, it implies that the ball will land closer to the

hole. What can he conclude?

A) There is no correlation between amount of time before hitting and distance from the hole.

B) There is a correlation between amount of time before hitting and distance from the hole. There may or may not be causation. Further studies would

have to be done to determine this.

C) There is a correlation between amount of time before hitting and distance from the hole. There is probably also causation. This is because there is a

decrease in the distance from the hole with an increase in the amount of time before hitting.

B) i correct

Step-by-step explanation:

According to the examination, the longer a student takes to hit, then the closer the ball is to the hole, therefore there is correlation. Now, this doesnt imply that in order to make it closer to the ball you just need to wait longer because that doesnt seem true. Probably the most skilled students take some time to hit in order to make the hit accurate, thus the longer the hit the closer the ball is to the hole (because they were hit by skilled students). This is just an hypothesis though, but it is still true that it will be needed more studies to determine if there is causation or not; so i stay with option B.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
