Answer:
$ 60
Step-by-step explanation:
p(x) = 7x + 25
f(1) = 2.1² + 3 = 5
p(f(1)) = p(5) = 7 . 5 + 25 = 35 + 25 = 60
so he get $ 60 for 5 hours work with tips

The value of the expression (6¾) × -11.5 is; -77⅝
We want to find the value of;
(6¾) × -11.5
Let us change 6¾ to improper fraction to get;
27/4
Also,let's change -11.5 to an improper fraction to get; -115/10
Thus;
(6¾) × -11.5 = 27/4 × -115/10
>> (-115 × 27)/(40)
>> 3105/40
>> -77⅝

Answer: For 95% Confidence Interval:
Upper Limit = 110.2
Lower Limit = 97.8
95% Confidence Interval = [97.8, 110.2]
Step-by-step explanation:
Given that,
Mean(M) = 104
Standard Deviation(SD) = 10
Sample Size(n) = 10
Formula for calculating 95% Confidence Interval are as follows:
Standard error(SE) =
= 
= 3.164
⇒ M ±
× SE
= 104 ± (1.96)(3.164)
= 104 ± 6.20
∴ Upper Limit = 104 + 6.20 = 110.2
Lower Limit = 104 - 6.20 = 97.8
So,
95% Confidence Interval = [97.8, 110.2]
