1. b = $95.94 / 6
= $15.99

t = $15.99 / 20
= $0.80

2. A: $1.28 / 8 = $0.16 per oz
B: $1.68 / 12 = $0.14 per oz

Difference: $0.02 per oz

Cost of a crate of floor tiles = $95.94

The crate has 6 boxes of floor tiles. This means 6 boxes of tiles cost $95.94

Now each box has 20 floor tiles.

So, total tiles in a box are : $t=6\times20=120$ tiles

Now, cost of 6 boxes = $95.94

So, cost of 1 box (b) = $b=\frac{95.94}{6}$ = $15.99

20 tiles cost $15.99

Hence, 1 tile (t) will cost = $\frac{15.99}{20}$ = $0.799 ≈ $0.80

Brand A contains 8 fluid ounces and costs $1.28.

Cost of per fluid ounce = $\frac{1.28}{8}$ = $0.16

Brand B contains 12 fluid ounces and costs $1.68.

Cost of per ounce = $\frac{1.68}{12}$ = $0.14

Difference between both the per ounce costs = $0.16-0.14$ = $0.02

How can probabilities be used to make fair decisions?

GarryVolchara [31]

he magician starts with the birthday boy and moves clockwise, passing out 100100100100 pieces of paper numbered 1111 through 100100100100. He cycles around the circle until all the pieces are distributed. He then uses a random number generator to pick an integer 1111 through 100100100100, and chooses the volunteer with that number.

Method2: The magician starts with the birthday boy and moves counter-clockwise, passing out 75757575 pieces of paper numbered 1111 through 75757575. He cycles around the circle until all the pieces are distributed. He then uses a random number generator to pick an integer 1111 through 75757575, and chooses the volunteer with that number.

Method 3\: The magician starts with the birthday boy and moves clockwise, passing out 30303030 pieces of paper numbered 1111 through 30303030. He cycles around the circle until all the pieces are distributed. He gives #1111 to the birthday boy, #2222 to the next kid, and so on. He then counts the number of windows in the room and chooses the volunteer with that number.

yes probabilites can be used to make fair ones

If 28% of a sum is 100.80 what is the sum

Sveta_85 [38]

$360.00*.28= 100.80

Or do a portion 

28%/100%=100.8/x 

Then cross multiply 

10080=28x 

x=360
