The answer is D, because if you add up all the numbers you'll get 107, and than if you divide 107 by the amount of numbers there are (which is 11) you'll get 9.7 as the mean. And if you put all the numbers in order and cross off one on each side one by one the last one will be 10, which is the median. And if you look at the numbers, you'll see there is three 15's which is more than any other number so 15 is the mode.
Hope this helps! :)
Answer:
r = - 6
Step-by-step explanation:
Given
6r + 7 = 13 + 7r ( collect terms in r on the left and numbers on the right )
Subtract 7r from both sides
- r + 7 = 13 ( subtract 7 from both sides )
- r = 6 ( multiply both sides by - 1 )
r = - 6
Step-by-step explanation:
by using this equation
a(n) = a +(n-1)d
a= the first term in the sequance
d=the commen difference between two terms

Answer:
x = 
Step-by-step explanation:
Given
y = mx + b ( isolate the term in x by subtracting b from both sides )
y - b = mx ( divide both sides by m )
= x
Yes the answer is 1 you are correct
