It should be all real numbers, because if you plug in lets say a 1 that would be 8(1-3) = 8(1) -24  or a 2 that would be 8(2-3)= 8(2) -24
     8(-2) = 8 -24                                          8(-1) = 16 -24
      -16  = -16                                               -8    =    -8

Performing the indicated multiplication on the left side gives you:

8x-24=8x-24,

8x=8x

1=1 

These expressions are true for any real value of x and thus has infinitely many solutions...

A dealer decides to sell an antique card by means of an English auction with a reservation price of $200. There are two bidders.
Vinvika [58]

Answer:

Expected revenue = $400

Step-by-step explanation:

Expected revenue is given by the formula;

Expected revenue = Sum of x * p(x)

x = 200

x = 600

p(x) = 1/2

p(x) = 1/2

Substituting, we have;

Expected revenue = 200*1/2 + 600*1/2

                               = 100 + 300

                                = $400

Therefore, expected revenue = $400

An amusement park sells child and adult tickets at a ratio of 3:1. On Saturday, they sold 63 adult tickets. How many child ticke
nalin [4]

Answer:

The number of child tickets sold by the amusement park is 189.

Step-by-step explanation:

Let A represent the number of adult tickets and C represents the number of child tickets, therefore we have:

3:1 = C:A .................... (1)

Where;

C = ?

A = 63

Substituting for the value into equation (1), we have:

3:1 = C:63

This can be converted to solve for C as follows:

3 / (3 + 1) = C / (C + 63)

3 / 4 = C / (C + 63)

0.75 = C / (C + 63)

0.75(C + 63) = C

0.75C + (0.75 * 63) = C

0.75C + 47.25 = C

47.25 = C - 0.75C

47.25 = 0.25C

C = 47.25 / 0.25

C = 189

Therefore, the number of child tickets sold by the amusement park is 189.

What ratio is less than 15:24.these are the answer choices  > 1:2, 7:8, 19:24, 6:8
Drupady [299]
15:24 is divisible by 3, simplifying it down to 3:8. 19:24, 7:8, and 6:8 are all obviously larger than this ratio, and 1:2 can be equalized to 4:8, which is also bigger than 3:8, so none of the answer choices are less than 15:24.
