Probability is (outcome wanted)/(total possible outcomes). Total possible outcome is the whole area of the rectangle. Which is (18)(12)=216. The outcome wanted is just the area of the triangle. (0.5)(2)(5)=5. Now 5/216=0.02
Answer:
He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.
Step-by-step explanation:
After n consecutive serves, his total number of serves is going to be n+8, since he has already served 8 times. In the best case, his number of successful first serves is n+2.
His percentage of succesful first serves is the division of the number of succesful first serves divided by the total number of serves. So
We want 
. So
He needs 7 more consecutive successful first serves to raise his first serve percentage to 60%.
The center of the circle is (6,-3)

Answer:
y = 12
Step-by-step explanation:
Given
Green = 28
Red = 35
Yellow = y
Prediction of yellow = 16 of 100
Required
Determine y
First, we need to calculate the probability of yellow.
Probability of yellow =
Probability = Yellow/Total
Where
Total = Yellow + Red + Green
Total = y + 35 + 28
Total = y + 63
So,
Probability = y/(y + 63)
Also, the prediction of yellow is 16 out of 100.
Represent this as probability.
Probability = 16/100
Equate both expressions to solve for y
y/(y + 63) = 16/100
y/(y + 63) = 0.16
Multiply both sides by (y + 63)
y = 0.16(y + 63(
y = 0.16y + 10.08
Collect like terms
y - 0.16y = 10.08
0.84y = 10.08
Solve for y
y = 10.08/0.84
y = 12
