The manager of the zoo where the ticket price for an adult is $9.50 and the ticket price for a child is $6.50 wants to make at least $800 on a Saturday. Let x be the number of adult tickets and y be the number of child tickets. Choose the inequality that shows the numbers of tickets that need to be sold.

Step-by-step explanation:

9.5 in value of adult tickets. 6.5 is value of children's tickets. combined selling of all of them should be greater than or equal to 800 ("atleast" in the question shows it can be more but cannot be less)

Median : 66 .

Step-by-step explanation:

Given : 66, 51, 77, 68, 60, 75, 54, 80 29 64 66 67.

To find : What is the median of this set of data.

Solution : We have given the data set 66, 51, 77, 68, 60, 75, 54, 80 29 64 66 67.

Arranging in increasing  order :  29, 51, 54, 60 , 64 ,66, 66, 67, 68, 75, 77,80.

There are 12 numbers of set

Median = average of two middle terms

Median :   term.

Median  :  66.

Therefore, Median : 66 .
