Answer:

The mean price a randomly chosen customer pays for her or his burger is US$ 3.40

Step-by-step explanation:

Let's find out the mean of T (total price a randomly chosen customer pays for their burger), this way:

Mean of T = 0.4 * $ 2 + 0.5 * $ 4 + 0.1 * $ 6

Mean of T = 0.8 + 2 + 0.6

Mean of T = US$ 3.40

The mean price a randomly chosen customer pays for her or his burger is US$ 3.40

1, 2, 4, 8, or 16 since each puppet has the same number of blue buttons and red buttons. so if we assume he allotted one red and one blue button for every puppet he can make 16 pupets as he have only 16 red button.

Answer:

If we have assumed, he allotted 1 red and 1 blue button for every puppet.

He can make 16 puppets as he have only 16 red button.

Ms rodriguez planted 24 tulips in her flowerbed. of the tulips 1/3 are red how many tulips are red

Answers


You would do 1/3 * 24

Which would give you 8

So 8 are red
Hey there,

So in order to do this you need to think of 24 as 1 whole

Once we know that and we know that 1/3 of the 24 tulips are red

Therefore, in order to find this we have to divide the 24 tulips by 3 in order to find how many tulips are red

24/3 = 8

Therefore, 8 out of the 24 tulips are red.

At discount copy,12 copies cost $0.66. Melissa needs 56 copies . How much should they cost ? ....show work

Answers

Cost of 12 copies that Melissa needs to pay = $0.66
Then
Cost of 1 copy that Melissa needs to pay = (66/12) dollars
                                                                   = 11/2 dollars
Now
The cost of 56 copies that Melissa has to pay =(11/2) * 56
                                                                          = 11 * 28 dollars
                                                                          = 308 dollars
So Melissa needs to pay $308 for 56 copies.I hope the procedure is clear enough for you tounderstand. In future you can use this procedure to solve similar problems in future.
56 copies* ($0.66/ 12 copies)= $3.08
(Note that the unit cancels out so you get the answer)

The final answer is $3.08~
