Answer: 375 bolts
Step-by-step explanation:
Just do 225*(40/24)
2.4 minus 1.57 = 0.83
Therefore, the answer is 0.83
To get 10% of 40, you move the decimal point one way to the left. So 10% of 40 is 4
Now you need 2% and because you know 10% is 4, you divide that by 10 and multiply it by 2 because of the 2%
4/10=.4 .4•2=.8
Now you add them
4+.8=4.8
12% of 40 is 4.8
Answer:
a) The probability that exactly 17 of them enroll in college is 0.116.
b) The probability that more than 14 enroll in college is 0.995.
c) The probability that fewer than 11 enroll in college is 0.001.
d) It would be be unusual if more than 24 of them enroll in college since the probability is 0.009.
Step-by-step explanation:
We can model this with a binomial distribution, with n=29 and p=0.65.
The probability that k students from the sample who graduated from high school in 2012 enrolled in college is:
a) The probability that exactly 17 of them enroll in college is:
b) The probability that more than 14 of them enroll in college is:
c) Using the probabilities calculated in the point b, we have:
d) The probabilities that more than 24 enroll in college is:
