Answer:
0.5161
Step-by-step explanation:
There is a lot of unnecessary information in this question. We only need info for Smartphone A users since our sample size consists of entirely Smartphone A users, and it's asking about them. So ignore any info that isn't about Smartphone A users.
We have (for Smartphone A users):
x = 15, s = 6.4, n = 16
We want: P(14.5 < x < 17)
We need to find the z-scores for the values of 14.5 and 17 using the data for smartphone a users.
See attached photo for the calculation of the 2 z-scores and the probabilities
On a standard die, or number cube, there are six faces, each with a number one through six written once. Five is written only once on here, so the odds of rolling a five are one in six. Thus, the odds of not rolling a five are five in six.
Answer: (2,-1)

Step-by-step explanation:
34.40 divided by .85 is 29.24. Subtract the diffrence of 34,40 and 29.24 which is $5.16. Hope this helps :)
The equation of an elementary exponential function with base b is
y=b∧x with domain Dx=R or x∈R. (R set of real numbers).
Good luck!!!
