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

Answer:
b) 1.34
Step-by-step explanation:
The z score is used to determine the number of standard deviations by which the raw score is above or below the mean. If the z score is positive then the z score is above the mean while for a negative z score implies that it is below the mean. The z score is given by:

For the largest 9%, the score is 100% - 9% = 91% = 0.91
From the normal distribution table, the z score that corresponds to 0.91 is 1.34
If you multiple the net by 2, you will get 2720, and dividing it from 940, you will get 35%. B is the correct answer. :)
