Let's assume
the number of hours Susan jogs at the increased speed is 't' hours
Since, increased speed is 6 miles per hour
after 't' hours , she travles with increased speed is 6*t miles
She starts off with a half-hour walk at a pace of 2 miles per hour
so, she travels distance
=0.5*2 miles
=1 miles
She travels a total of 4 miles
total distance is
=6t+1
now, we can set them equal
now, we can solve for t
Subtract both sides by 1
Divide both sides by 6
we get
so, the number of hours Susan jogs at the increased speed is 0.5 hrs.........Answer
The statements that are true about this study are:
- This study uses random sampling.
-
This study uses a control group.
-
This study uses a repeated measures design.
Random sampling occurs when each sample has an equal probability of being chosen in a study.
This is seen in the random selection of 100 children. The Control group was used with the first group that had no screen time.
The repeated measures design was also used when multiple measurements were taken during different weeks.

Answer:
98 degrees
Step-by-step explanation:
Construct a line parallel to the 2 given lines that passes through the vertex of angle 1.
We get the part of angle 1 below this line is 180 - 144 = 36 by same side interior angles.
We get the part of angle 1 above this line is 62 degrees by alternate interior angles.
meaning the total measure of angle 1 is 62 + 36 = 98
Simple, find what 6/11 and 67/99 is in decimal form
6/11=0.545454545 (repeating)
and
67/99=0.67676767 (repeating)
then do the same with your answer choices:
11/18=0.61111111 (repeating)
69/99=0.696969697 (too high)
24/33=0.727272727 (repeating) (too high)
26/55=0.472727273 (too low)
Then, from here it's simple to see what the answer is, 11/18, is your answer.
Answer:
S= 37.72
Step-by-step explanation:
Add
13.27+24.45=S
Simplify
37.72=S
S=37.72
Hope this helps :)
