Let U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, A = {1, 3, 5, 7, 9}, B = {2, 4, 6, 8, 10}, and C = {1, 2, 4, 5, 8, 9}. List the element
Leto [7]
Answer:
Step-by-step explanation:
Required
Determine
Solving
implies that elements in U but not in C
Since
<em>Because there's no intersection between both</em>
Solving
First, we need to determine A n C
Solving
First, we need to determine B n C
So:
A because -2 -3 -4 ext are less than -1
Answer:
$1.46
Step-by-step explanation:
To find the original price of the game, write a proportion. $1.54 is the amount after a 5.5% tax rate. This means he paid 105.5% on the original price.
Find y by cross multiplying numerator and denominator of each fraction.
1.54(100) = 105.5y
154 = 105.5y
1.46 = y
