Consider the probability that fewer than 46 out of 134 students will not pass their college placement exams. Assume the probability that a given student will not pass their college placement exam is 98%. Specify whether the normal curve can be used as an approximation to the binomial probability by verifying the necessary conditions. a. Yes
b. No

b. No

Step-by-step explanation:

Binomial approximation to the normal:

Binomial distribution has n trials, with p probability.

If

and , it can be approximated to the normal distribution.

Assume the probability that a given student will not pass their college placement exam is 98%.

This means that

134 students:

This means that

Necessary conditions:

Since the necessary condition n(1-p) < 10 is not satisfied, the answer is No, given by option b.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
