Answer:
q = 36/7 or 5 1/7
Step-by-step explanation:
q · 7/9 = 4
Multiply each side by 9/7
q · 7/9 *9/7 = 4*9/7
q = 36/7
If we want it as a mixed number instead of an improper fraction
7 goes into 36 5 times with 1 left over
q = 5 1/7
Answer:
a) 0.004
b) 0.9609
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 76503
Standard Deviation, σ = 8850
We are given that the distribution of annual salaries is a bell shaped distribution that is a normal distribution.
Formula:

a) P(salary greater than 100,000)
P(x > 100000)


Calculation the value from standard normal z table, we have,

b) P(sample mean annual salary falls between 70,000 and 80,000 dollars)
Sample size, n = 20
Standard error due to sampling =

Answer:
The number in the middle is 60.
Step-by-step explanation:
The 2nd number = A
The 3rd number = B
The 4th number = C
Given:
(1) 130 + A + B = 300
(2) A + B + C = 200
(3) B + C + 10 = 100
Now, the work:
(2) can be modified to become A + B = 200 - C
Now, we can insert that into (1) and get the following;
130 + (200 - C) = 300
Open parentheses, simplify, you get C = 330 - 300.
C = 30
Using (3), we use above answer to get B + 30 + 10 = 100
Calculate, and get B = 100 - (30 + 10)
Simplify,
B = 60
There is your answer!
