Answer:

4t^2 - 28t + 49

Step-by-step explanation:

(2t - 7)^2

Use FOIL.

(2t - 7)^2 =

= (2t - 7)(2t - 7)

= 4t^2 - 14t - 14t + 49

The number of adult tickets is the same as the number of child (age5-12)tickets.A total of 38 tickets was purchased. What is the
Nutka1998 [239]

Answer:

$760

Step-by-step explanation:

The number of adult ticket is the same as the number of (age 5-12) tickets.

Let the number of adult ticket be x

Number of (age 5-12) tickets be x

Total ticket sold = 38

x + x = 38

 2x = 38

  x = 19

Cost of each adult ticket = $23

Total cost for 19 such tickets = 23×19

                                               = $437

Cost of each (age 5-12) ticket = $17

Total cost for 19 such tickets = 19×17

                                               = $323

Total cost of 38 tickets = 437 + 323

                                       = $760

Hence, the total cost of tickets is $760

Decide whether the following statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain yo
schepotkina [342]

Answer:

A. is the correct one. The statement makes sense.

Step-by-step explanation:

A. This is true because if you make your graph starting from the lowest value then the graph will use more space to fit the data and it will make it look bigger. Also, the variation will seem higher because it will feel that you are increasing it from 0, so the relative increase will be higher.

B. Reducing the range of the vertical axis will increase the relative size of variation, not make it decrease, as we explained in A.

C. Even though it is technically certain that the data shown is the same as before, the way to show data also matters. And by making changes on the presentation of your data you can obtain different results on the impression that leaves to people.

D. This is just false, because you are indeed dereasing the range of the vertical axis, not increasing it.
