Answer:
0.998 is the probability that the average money spent by a sample of 40 shoppers is within $10 of the actual population mean.
Step-by-step explanation:
We are given the following information in the question:
Standard Deviation, σ = $21.51
We are given that the distribution of average money spend is a bell shaped distribution that is a normal distribution.
Formula:
We have to find:
P( average money spent is within $10 of the actual population mean.)
Calculation the value from standard normal z table, we have,
46/10=4.6 Answer: 1/10 of 46 is 4.6
56x10=560 Answer: 560
1 combine like terms
4x - 3x = x
8y+2y=10y
2. Simplify the equation
x+10y
Answer:
The answer to your question is: k + 10
Step-by-step explanation:
x³ + 4x² - 7x + k divided by (x - 2)
Using synthetic division
1 4 - 7 k 2
2 12 10
1 6 5 k + 10
x² + 6x - 5 remainder = k + 10
Answer:
Part A:
I have attached the graph of this system of inequalities.
Part B:
Plug in (8,10) into both equations
10 > 3(8) + 10
10 > 24 + 10
10 > 34
This is false!
10 < (-3/4)(8) - 1
10 < (-3)(2) - 1
10 < -6 - 1
10 < -7
This is also false!
So, (8,10) is not included in the solution area for the system.
Step-by-step explanation:
