Interquartile range is when you subtract Q3 and Q1. The Q3 is 54, Q1 is 42. We subtract that together and we get 12, so the second option.
Answer:
x = 10
Step-by-step explanation:
Adjacent angles add to 180 degrees, so set the angles equal to 180
(7x + 12) + (9x + 8) = 180
- 12 - 12
7x + (9x + 8) = 168
- 8 - 8
7x + 9x = 160
16x = 160
/16 /16
x = 10
The answer will be $13.72 for 7 bags of popcorn.
to find this answer, you first take 5.88 and divide it by 3 to find out how much one bag costs.
the answer to 5.88/3 is 1.96, so you multiply 1.96 by 7 to get the answer of how much 7 bags of popcorn will cost.
hope this helps!
