Answer:
Choice B) No.
Step-by-step explanation:
When she starts , she does a sit-up every 222 seconds.
But as she gets tired, each sit-up takes longer and longer to do.
It means, each sit-up takes more time than she did at beginning.
So, it is NOT proportional to the time.
If it is proportional, she should take constant number of sit-ups even she get tired.
Answer:
angle l = 115
angle k = 115
angle j = 114
angle i = 66
Step-by-step explanation:
angle l = it is opposite to 115 so its the same
angle k = opposite opposing angles with angle l
angle j = 180-66=114 (between 2 parallel lines the sum of 2 angles is 180)
andle i = 180-114=66 (straight line = 180 degrees so subtract angle j to get i)
Answer:
24 walls per volunteers
Step-by-step explanation:
given that there are 864 walls and that there are 36 volunteers
if the walls are divided evenly over the 36 volunteers,
each volunteer would paint,
= 864 walls ÷ 36 volunteers
= 24 walls per volunteers

Answer:
C
Step-by-step explanation:
First we find the z-score.
z = (x - μ) / σ
z = (520 - 500) / 60
z = 0.33
Using a calculator or z-score table:
P(z < 0.33) = 0.6293
The probability is approximately 63%. Answer C
