Answer:
0.0014 is the required probability.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 180000 per day
Standard Deviation, σ = 15000 per day
We are given that the distribution of number of viewers is a bell shaped distribution that is a normal distribution.
Formula:
P(number of viewers is more than 1000000 in a week)
Calculation the value from standard normal z table, we have,
0.0014 is the probability that the number of viewers is more than 1000000 in a week.
Answer:
There is a 99.94 percent that Alex will not live to be 100 years old.
Step-by-step explanation:
100% - 0.06% = 99.94
By dividing the price per gallon, we see that for every gallon he pays three dollars.

Given parameters:
First term of the sequence = x
Second term = x + 2
Third term = x + 4
Sum of the first three terms = 72
Unknown:
First term of the sequence = ?
Solution:
The sum of the first three terms is unknown;
(x) + (x + 2) + (x + 4) = 72
Solve for x;
x + x + 2 + x + 4 = 72
3x + 6 = 72
3x = 72 - 6
3x = 66
x = 
= 22
The first term of the sequence is 22
Answer:
Increasing: -10<x<-8. 8<x<10. -2<x<0.
Deacresing: 3<x<7.
Neither Increasing nor decreasing: -8<x<-5
