Answer:
a) 0.194
b) $440.8
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $9.40
Standard Deviation, σ = $4.40
Formula:
Standard error due to sampling =
a) P(tips from 40 parties > $400)
Thus, the average pay is
P(x > 10)
Calculation the value from standard normal z table, we have,
b) We have to find the value of x such that the probability is 0.01
Calculation the value from standard normal z table, we have,
Thus, the mean tip is $11.02
Tip for 40 parties =
Thus, he earns $440.8 on the best 1% of such weekends.
Answer:
(g ο f)(0) < (f ο g)(3.5) < (g ο f)(- 2) < (f ο g)(0) < (g ο f)(3.5) < (f ο g)(-2)
Step-by-step explanation:
We are given that f(x) = 2x² and g(x) = x - 2
Therefore, (f ο g)(x) = f[]g(x)] = 2(x - 2)² ......... (1)
and (g ο f)(x) = g[f(x)] = 2x² - 2 ........... (2)
Therefore, (f ο g)(-2) = 32 {from equation (1)}
(f ο g)(3.5) = 4.5 {From equation (1)}
And (f ο g)(0) = 8 {From equation (1)}
Now, (g ο f)(- 2) = 6 {From equation (2)}
(g ο f)(3.5) = 22.5 {From equation (2)}
And (g ο f)(0) = -2 {From equation (2)}
Therefore, if we arrange those values from least to greatest value, then we will get
(g ο f)(0) < (f ο g)(3.5) < (g ο f)(- 2) < (f ο g)(0) < (g ο f)(3.5) < (f ο g)(-2) (Answer)
Answer:
7.9 ounces
Step-by-step explanation:
Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.
For this problem we can use a simple Rule of Three property to solve this problem.
=
Now we cross multiply 3.5 by 39.5 and then divide the answer by 17.5 to get x like so,
Finally, we can see that 7.9 ounces should be added to the 39.5 gallons of gasoline.
