Answer:
Step-by-step explanation:
Alright so just like the other problem we have to use ratios to find if it is parallels or not. In order for AC and DE to be parallels the sides CE and AD and DB and EB have to have the same ration. So in answer c if you do 24/22.5 you would get 1.066666667. So then to find the length of EB we subtract 24 from 40 to get 16 and then we do 16/15 to find out if the ratios are the same. And indeed they are the same both equaling 1.066666667. If you were to divide CE/AD and DB/EB none of the answers would be the same leading to c being the correct answer
Answer:
23.25 MPH
Step-by-step explanation:
7 3/4 x 3 = 23.25
1/3 x 3 = 3/3 = 1
So for 1 hour she will ride 23.25 MPH :D
30 + 20 + 30 + 20 = 100
30 x 10% = 3 + 30 = 33
20 x 5% = 1 + 20 = 21
33 + 21 + 33 + 21 = 108
100 / 108 = 0.925925926 = 0.93 = 93%
100% - 93% = 7%
7% increase
Answer: 45
=====================================================
Work Shown:
n = number of rolls = 150
p = probability of rolling a "1" = 0.3
n*p = expected number of "1"s that show up out of the 150 rolls
n*p = 150*0.3
n*p = 45
We expect about 45 ones will show up.
