Answer: A- $85
B- $14,250
Step-by-step explanation:
Answer:
The probability that the number of free throws he makes exceeds 80 is approximately 0.50
Step-by-step explanation:
According to the given data we have the following:
P(Make a Throw) = 0.80%
n=100
Binomial distribution:
mean: np = 0.80*100= 80
hence, standard deviation=√np(1-p)=√80*0.20=4
Therefore, to calculate the probability that the number of free throws he makes exceeds 80 we would have to make the following calculation:
P(X>80)= 1- P(X<80)
You could calculate this value via a normal distributionapproximation:
P(Z<(80-80)/4)=1-P(Z<0)=1-50=0.50
The probability that the number of free throws he makes exceeds 80 is approximately 0.50
3/4x + 3 - 2x = -1/4 + 1/2x + 5 ...multiply everything by 4 to get rid of fractions
3x + 12 - 8x = - 1 + 2x + 20...simplify
-5x + 12 = 2x + 19
-5x - 2x = 19 - 12
-7x = 7
x = -7/7
x = -1
