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

d 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.

Answer:

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.

A tunnel is 300 feet deep and makes an angle of 30 with the ground .
Goshia [24]

Answer:

\boxed{C.\:\: 600\:feet}

Step-by-step explanation:


The tunnel, the ground and the depth of the tunnel form a right angle triangle.

The length of the tunnel is the hypotenuse of the right triangle that has been formed.


Let the length of the tunnel be m\: feet.


Using the sine ratio, we obtain;


\sin(30\degree)=\frac{Opposite}{Hypotenuse}


The length of the opposite side is 300\:feet


We substitute the given values to obtain;


\sin(30\degree)=\frac{300}{m}


\Rightarrow \frac{1}{2}=\frac{300}{m}


We cross multiply to obtain;


m=300\times2


m=600\:feet


Therefore the correct answer is C.

lana [24]

Answer: Yes ,because it isn't the same the number since the number of digits aren't the same so you make it the same number of digits by putting 0 in the back so 1.7 turns to 1.700 to make it the same digits of 1.700.
