Last month he sold $9000 worth of merchandise.
Salesman earns 6% =6/100=0 .06
What is the meaning of commission?
Earning a commission means that a portion of your salary is based on the amount of sales revenue you generate or another similar performance-based goal.
So we have to determine 6% of 9000
We can be written as

Graph the solution set of the inequality 1/4 x >= - 2
Answer:
-8 is one point and the arrow goes to 10
Step-by-step explanation:
The solution of the inequality is x≥ -8.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
1/4 x ≥ - 2
Now, the solving the inequality for x we get
x ≥ -2 (4)
x≥ -8
So, the value of x should be the region where values of x should be equal to -8 and greater than -8.
That means x ≠ -7, -6, -5, ....0,1, 2, 3....

Given is a line.
The two points that the line passes through is given.
(4, 8) and (2, 2)
Slope of a line passing through two points can be found as,
Slope = (Change in y coordinates ) / (Change in x coordinates)
Here the points are (4, 8) and (2, 2),
Slope = (2 - 8) / (2 - 4)
= -6 / -2
= 3

Once upon a time, there was a flock of doves that flew in search of food led by their king. One day, they had flown a long distance and were very tired. The dove king encouraged them to fly a little further. The smallest dove picked up speed and found some rice scattered beneath a banyan tree. So all the doves landed and began to eat.
Suddenly a net fell over them and they were all trapped. They saw a hunter approaching carrying a huge club. The doves desperately fluttered their wings trying to get out, but to no avail. The king had an idea. He advised all the doves to fly up together carrying the net with them. He said that there was strength in unity.
Each dove picked up a portion of the net and together they flew off carrying the net with them. The hunter looked up in astonishment. He tried to follow them, but they were flying high over hills and valleys. They flew to a hill near a city of temples where there lived a mouse who could help them. He was a faithful friend of the dove king.

a. Compute the range and interquartile range.
b. Compute the sample variance and sample standard deviation.
c. A sample of air quality index readings for Anaheim provided a sample mean of 48.5,a sample variance of 136, and a sample standard deviation of 11.66. What comparisons can you make between the air quality in Pomona and that in Anaheim on the basis of these descriptive statistics?
Answer:
Range = 32 ; IQR = 13 ; Variance = 92.75 ; Standard deviation = 9.63
Step-by-step explanation:
Given the data:
28, 42, 58, 48, 45, 55, 60, 49, 50
Reorderd data: 28, 42, 45, 48, 49, 50, 55, 58, 60
The range: maximum - minimum
Range = 60 - 28 = 32
Interquartile range (IQR) : Q3 - Q1
Q3 = 3/4(n+1) th term. ; n = sample size
Q1 = 1/4(n+1)th term.
Using calculator :
Q3 = 56.5 ; Q1 = 43.5
IQR = 56.5 - 43.5 = 13
The variance :
Σ(X - m)^2 / n-1
m = Σx / n
Mean, m = 435 / 9 = 48.33
Variance :
[(28-48.33)^2 + (42-48.33)^2 + (45-48.33)^2 + (48-48.33)^2 + (49-48.33)^2 + (50-48.33)^2 + (55-48.33)^2 + (58-48.33)^2 + (60-48.33)^2] / 8
= 742.0001 / 8
= 92.75
Standard deviation = sqrt(Variance):
Sqrt(92.75) = 9.63

Casper write the algebraic expression 5b + 3.79. I represents the total cost, in dollars, of buying 5 bagels and a container of cream cheese. Identify any variables, coefficients, and termsin the expression. Tell me what each represents
Answer:
5 is a co efficient and b is a variable together is a term, 3.79 is a constant/term the whole equation is an expression.
The total cost of buying 5 bagels and a container of cream cheese is $28.79 and in the expression 5 is constant, b is variable, and 3.79 is constant representing the cost of the container.
What is an expression?An expression is a combination of some mathematical symbol such that an arithmetic operator and variable such that all are constrained and create an equation.
For example 3x +5y
Given the expression for the total cost,
C = 5b + 3.79 where b is the number of bagels.
Cost of 5 bangles →
C = 5(5) + 3.79 =$ 28.79
Cost of container = $3.79
Thus b is the only variable and 5b represents the cost of bagels while by the sum of container cost 3.79 total costs are created.
Hence "The total cost is $28.39 and container cost is $3.79 while b is variable".
