OleMash [197]

Answer:

3.125 mg/ oz

Step-by-step explanation:

Amount of instant tea = 24 ounces

Amount of green tea = 12 ounces

Caffeine in instant tea = 24/8*30= 90 mg/oz

Also, caffeine in green tea = 12/8*15 =22.5 mg/oz.

Total amount of mixture= 24+12= 36 ounce

Total amount of caffeine in the mixture = 90+22.5 = 112.5 mg/oz

Caffeine per ounce in the final mixture = 112.5 / 36 = 3.125 mg/ oz

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.

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