KonstantinChe [14]

Answer:

Step-by-step explanation:

A

According to the exercise we can say that the explanatory variable will be hours / weeks of study.

The response variable is GPA.

B

We definitely found that between the variables there is a weak or fragile relationship, neither negative nor positive nor linear.

C)

1.Observational study, since we observe that the only variables that will influence the results of the study are the observations of the students

2.No. This study is observational and its characteristics are not sufficient to conclude that studying more hours leads to obtaining a higher GPA.

PLEASE SOVEL THIS I WILL GIVE OUT 20 POINT
Anettt [7]

Answer:

  21.25 seconds

Step-by-step explanation:

In miles per second, the speed of the jet is ...

  (720 mi/h)/(3600 s/h) = 1/5 mi/s

The speed of the sound is the same:

  (1 mi)/(5 s) = 1/5 mi/s

Then the rate of closure between the airplane and the sound is ...

  (1/5 mi/s) +(1/5 mi/s) = 2/5 mi/s

To find the time required to close a gap of 8 1/2 miles, we can use the relation ...

  time = distance/speed

  time = (8.5 mi)/(0.4 mi/s) = 21.25 s

The pilot will hear the thunder 21.25 seconds after the flash.
