Answer:
2x - 18
$3,382
Step-by-step explanation:
x = number of dollars gained last month
this month:
twice the amount = 2x
minus $18 = 2x - 18
x = 1,700
2x - 18
2(1700) - 18
3,400 - 18
$3,382
Product of 6 and a number means 6 times something (let's call it x)
6 times x or 6x
product is multipled by 9
(6x) times 9 or 9(6x)
using associative property or commutative I forgot
9(6x)=(9)(6)(x)=(54)(x)=54x
Answer:
174 because 290 divided by 10 is 29 so then 29 times 6 is 174.
Hope this helped if not sorry.

What is the interquartile range of the data set?
8_murik_8 [283]
Answer:
IQR = 8
Step-by-step explanation:
The interquartile range (IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁
We require the data arranged in ascending order and to find the median Q₂
The median is the middle value of the data arranged in ascending order.
8, 9, 9, 9, 10, 11, 13, 15, 17, 18, 22
↑ Q₂
The upper quartile is the middle value of the data to the right of the median
13, 15, 17, 18, 22
↑ Q₃
The lower quartile is the middle value of the data to the left of the median
8, 9, 9, 9, 10
↑ Q₁
IQR = Q₃ - Q₁ = 17 - 9 = 8
