Suppose you roll not die. Find the Probability of not rolling an even number
irina [24]
I think you mean roll a die. To do this you would find the number of non-even numbers and divide that number by the total amount of numbers on the die. On a normal six-sided die these numbers would be 1,3,and 5, so your probability of not rolling an even number would be 50%

During a furniture sale, Dorothy paid $20 for new couch cushions. If the discount percentage is given in the first column, find
DochEvi [55]
<h3>Answers:</h3><h3>First box = 57.14</h3><h3>Second box = 80</h3>

=============================================

Explanation:

If you save 65%, then you pay the remaining 35%

0.35x is the final price when x is the original price

0.35x = 20 solves to x = 57.14 approximately after dividing both sides by 0.35

57.14 goes in the first box

--------------

This must mean 80 goes in the other box.

Here's the steps on how to get 80

If you save 75% then you pay the remaining 25%

0.25x = 20

x = 20/0.25

x = 80

80 goes in the second box
