A researcher was interested in the relationship between a swimmer's hand length and corresponding time to complete the 100 meter freestyle. The researcher selected a random sample of twenty swimmers from all participants in a swim competitionAssuming all conditions for inference are met which of the following significance tests should be used to investigate whether there is convincing evidence, at a 5 percent level of significance, that a longer hand length is associated with a decrease in the time to complete the 100-meter freestyle?

i think it would be c

mark brainliest if im right

step-by-step explanation:

i think the answer is 90 hope this

well, if it's triangular garden, the triangle could represent the garden.

hey there! : )

4y < -4

we need to isolate y. we can do this by simply dividing both sides by 4.

4y ÷ 4 > -4 ÷ 4

simplify.

y > -1

5 - y > 0

once again, we need to isolate y, so we can start off by subtracting 5 from both sides.

5 - y - 5 > 0 - 5

simplify.

-y > -5

divide both sides by -1.

** remember that when dividing any side by a negative, you must switch the sign! **

-y ÷ -1 < -5 ÷ -1

simplify.

y < 5
