This sign shows admission fees and ticket prices for a museum :
General Admission: $18
Tickets to Special Exhibits $7
Tickets to Movies $6
Note: Tickets to the Special Exhibit and the Movie are in addition to the General Admission fee
The next day, another group spent a total of $61. Each person in this group paid for general admission, and one person bought a special exhibit ticket. How many people were in this group?
If only one person bought a special exhibit ticket, the amount spent on general admission = 61 - 7 = $54
Since everyone would have to pay the general admission ticket, we can determine the number of people in the group
number of people in the group = total amount spent on general admission / price of general admission per person
= $54 / $18 = 3
Answer:
21, 144, 12
Step-by-step explanation:
Given that a sample of 30 distance scores measured in yards has a mean of 7, a variance of 16, and a standard deviation of 4.
Let X be the distance in yard.
i.e. each entry of x is multiplied by 3.
New mean variance std devition would be
E(3x) = 
Var (3x) = 
Std dev (3x) = 
Thus we find mean and std devition get multiplied by 3, variance is multiplied by 9
