Answer:
Hence, the probability that seven or more of them used their phones for guidance on purchasing decisions is 0.7887
Step-by-step explanation:
We are given the following information in the question:
We treat people using phones in the store for guidance as a success.
P(People use phone for guidance) = 57% = 0.57
Then the number of people follows a binomial distribution, where
Formula:

where n is the total number of observations, x is the number of success, p is the probability of success.
Now, we are given n = 14 and x = 7
We have to evaluate:

Hence, the probability that seven or more of them used their phones for guidance on purchasing decisions is 0.7887
Answer:
35
Step-by-step explanation:
18+17=35
Answer:
22 1/8 mm.
Step-by-step explanation:
First add the whole numbers, then the fractions:
3 + 5 + 5 + 7 = 20
7/8 + 7/8 + 3/16 + 3/16 Change the 7/8's to 14/16:
= 14/16 + 14/16 + 3/16 + 3/16
= 28/16 + 6 /16
= 34 /16
= 2 2/16
= 2 1/8
So the final answer is 20 + 2 1/8
= 22 1/8 mm.
