Answer:
D
Step-by-step explanation:
the median is the middle value of a data set in ascending order
If there is not an exact middle then it is the average of the values on either side of the middle
Arrange data in ascending order
15, 17, 19, 21, 23, 25, 26, 28, 28, 30
the middle is between 23 and 25 , hence
median = 
= 
= 24
,(6.1-3.1)/(-5.5-2.5) = 3/-8 = -3/8=-.375
Answer:
2x-10+x+x+10=180, or 4x=180
Step-by-step explanation:
So since the total is 180, you add them all up like an equation.
So,
2x-10+x+x+10
Combine like terms
4x=180
x=45
Then plug it back in to the equations.
x=45
(2x-10)=80
(x+10)=55
$1,380 per month and a commission of 7.5% can be translated to
$1,380 + 7.5s, s = sales made within the month
salesperson has a paycheck of $4,132.50
$4,132.50 = $1,380 + 7.5s
4,132.50 - 1380 = 1,380 + 7.5s - 1380 --- Subtract 1380 from both sides
2752.5 = 7.5s --- Simplified
(2752.5)/7.5 = (7.5s)7.5 ---Divide both sides by 7.5
367 = s
Answer:
In general the formula is: P(n;n1,n2,...,nk) = n! n1! ... Any selection of r objects from A, where each object can be selected more than once, is called a combination of n objects taken r at a time with repetition.
