A college basketball player makes 80% of his freethrows. Over the course of the season he will attempt 100 freethrows. Assuming
BARSIC [14]

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

6^4 • 3^4 and 18^8, Are the expressions equivalent? I’m only talking about C in the photo.
Afina-wow [57]

Hey there!

6^4 * 3^4 = ?

6^4

= 6 * 6 * 6 * 6

= 36 * 36

= [1,296]

3^4

= 3 * 3 * 3 * 3

= 9 * 9

= [81]

1,296 * 81

= [104,976]

6^4 * 3^4 = [104,976]

Now let’s see if 18^8 is equivalent to 18^8

18^8

= 18 * 18 * 18 * 18 * 18 * 18 * 18 * 18

= 324 * 324 * 324 * 324

= 104,976 * 104,976

= [11,019,960,576]

Therefore, 11,019,960,576 ≠ 104,976 because It is way too big to be equations answer

Answer: [NO], they aren’t equivalent because 18^8 is too big to equal to 6^4 * 3^4

Good luck on your assignment and enjoy your day!
