He went around 24 times and 4 times is a mile so 24/4 will tell us how many miles he biked. He biked 6 miles in thirty minutes. The formula distance = rate(time) will tell you how fast he is going.
6 = r(1/2) divide each side by 1/2 (The time has to be in hours)
12 = r
So he was going 12 miles an hour.
I'm not sure if this is correct but I made this into the equation 61.5=17+2.5x. I solved the equation and the answer I got is 17.8%
Answer:
After 7.5 seconds and a height of 0
Step-by-step explanation:
Answer:
P(a junior or a senior)=1
Step-by-step explanation:
The formula of the probability is given by:
P (AB) = P(A)
Where P(A) is the probability of occurring an event A, n(A) is the number of favorable outcomes and N is the total number of outcomes.
In this case, N is the total number of the students of statistics class.
N=18+10=28
The probability of the union of two mutually exclusive events is given by:
Therefore:
P(a junior or a senior) =P(a junior)+P(a senior)
Because a student is a junior or a senior, not both.
n(a junior)=18
n(a senior)=10
P(a junior)=18/28
P(a senior) = 10/28
P(a junior or a senior) = 18/28 + 10/28
Solving the sum of the fractions:
P(a junior or a senior) = 28/28 = 1
