Answer:
2.28%
Step-by-step explanation:
Given that:
µ = 40 minutes ; σ = 3.5.
x = > 47 minutes
Obtain the standardized score, Z
Zscore = (x - μ) / σ
P(x > 47) = (47 - 40) / 3.5
P(x > 47) = 7 / 3.5
P(x > 47) = 2
P(z > 2) = 0.02275
Hence, Probability that next pizza delivery takes over 47 minutes is 0.02275 = 2.275% = 2.28%
(a) The recurrence relation for the salary is
(b) The salary 25 years after 2017 will be $217044.85.
(c)
We can define the next year salary as
wit S0=$50000
If we extend this to 2 years from 2017 (n+2), we have
Extending to 3 years (n+3)
Extending to 4 years (n+4)
We can now express a general equation for S_n (salary at n years from 2017)
The salary at 25 years from 2017 (n=25) will be
the answer is 8500 as 4 is not greater than or equal to 5

I'm not sure about the first one on question 5 though.

2.3 x 12 = 27.6
27.6 > 27.1
First thing you need to do is make their units the same.
There are 12 inches in a foot so we convert 2.3 feet to inches by multiplying 2.3 by 12:
You can also approach it like this:
12in = 1 ft
So if we compare the two then we know that:
