Answer:

1 1/3

Step-by-step explanation:

The first thing that we need to know is how to divide fractions. In this case, we would use KCF(Keep Change Flip) Meaning that we KEEP 1/2 as is. CHANGE the division sign to a multiplication sign. FLIP 1/3 to 3/1.

The next step would be to solve. To do that we would look at our expression. 1 3 3

_ * _ = _

2 1 2

3/2 is an improper fraction. We need to convert it to a mixed number. To do that we would divide 2 by three. We get 1 remainder 1. So to put that in fraction form we would keep the whole number (1) and put the other 1 over three.

Thus your answer being: 1 1/3

Answer:

Step-by-step explanation:

Hello!

The objective of this test is to know if aerobic exercise modifies hippocampus activity. A random sample of 120 elderly men and women was taken and divided into two groups.

Group 1: Walked around a track three times a week.

Group 2: Did a variety of less aerobic exercises, including yoga and resistance training with bands.

After a year their brains were scanned showing that group 1 had an increase of 2% in their hippocampus and group 2 showed a decrease of 1.4%

a. True, this type of observational study can be the prelude to a more formal statistical study.

b. True, the explanatory variable is "type of exercise", it's the variable that the investigator suspects influence the hippocampus volume.

c. True, the objective of this experiment is to test if there is any modification on hippocampus volume, that's why the volume of the hippocampus was measured, before and after a year of exercise.

d. False, this is an observational study, you cannot establish a causal relationship between the two variables. Just inform you that there seems to be an association. To be able to generalize the results to all elderly population you need a more formal statistical experiment to support your conclusions.

I hope it helps!

Answer:

37.3% is the take off

Step-by-step explanation:

In ΔJKL, j = 74 cm, k = 14 cm and l=80 cm. Find the measure of ∠J to the nearest degree.

natita [175]

Answer:

∠J = 60°

Step-by-step explanation:

The Law of Cosines tells you ...

j² = k² +l² -2kl·cos(J)

Solving for J gives ...

J = arccos((k² +l² -j²)/(2kl))

J = arccos((14² +80² -74²)/(2·14·80)) = arccos(1120/2240) = arccos(1/2)

J = 60°
