lesya692 [45]

Answer: She will need 142 ft of curtain.

Step-by-step explanation:

Hi, first we have to convert the length of the curtain from inches to foot.

Since 1 inch = 1/12ft

For 24 inches:

24 inches x 1/12 = 2 ft

Since the company wants to make 71 curtains, we have to multiply the length of each curtain (2ft) by 71.

2ft x 71 = 142ft

She will need 142 ft of curtain.

You order seventeen burritos to go from a Mexican restaurant, seven with hot peppers and ten without. However, the restaurant fo

Kisachek [45]

Answer:

$P=0.369$

Step-by-step explanation:

In this binomial probability case, the success is to pick a burrito with hot peppers, there are 7 out of 17, the probability is p=7/17=0.4118. The formula is

$P=_nC_kp^k(1-p)^{n-k}$

Where n is the number of burritos taken at random, k is the number of success (burrito with hot peppers), p is the probability of success. $_nC_k$ denotes the number of combinations and its formula is:

$_nC_k=\frac{n!}{k!(n-k)!}$

At least two burritos have hot peppers means having two or three burritos, these two cases are calculated and sum to get the probability of at least two burritos that have hot peppers.

$P=_nC_kp^k(1-p)^{n-k}=\frac{n!}{k!(n-k)!}p^k(1-p)^{n-k}$
