Answer:
Commission is money paid to a person or a company for making a sale. It is usually a percent of the sale amount.
As per the given information,
Total monthly sales last month a salesman had $15,200.
Commission he made from those sales is $912.
To find the percent of salesman's commission:
Percentage of salesman commission =
=
On Simplify we get,
Percentage of salesman's commission of his total monthly sales is, 6%
3000 because if the hundredths place is 499 or less you round down but if its 500 or more you round up
First, solve 10x + y = -20 for y: y = -20 - 10x
Next, substitute -20 -10x for y in the second equation:
-20 - 10x = 2x^2 - 4x - 16.
Rearranging, 2x^2 + 6x + 4 = 0
Simplifying, x^2 + 3x + 2 = 0
The roots of this poly eqn are -1 and -2. Therefore, x = -1 and x = -2.
One by one, subst. these x-values into y = -20 - 10x to find the corresponding y-values.
Your answers should look like this: (-1, y) and (-2, y) (different values for y).
Answer:
5%
Step-by-step explanation:
(x)(320)=16
0.05
The percentage of the runners who have times less than 14.4 sec is 0.15%
The times of all 15-year old who run a certain race are approximately normally distributed with a given mean of 18 sec and a standard deviation of 1.2 sec.
We know that,
where,
X = raw score = 14.4
μ = mean = 18
σ = standard deviation = 1.2
Putting the values,
Finding the probability from the z score table, we get
P(z < -3) = 0.00135 = 0.135%
