Answer:b 10 .
Step-by-step explanation:
Regal theater sold 321 adult tickets and 227 children tickets.
Step-by-step explanation:
Given,
Cost of each adult ticket = $6.50
Cost of each child's ticket = $3.50
Total tickets sold = 548
Total worth of sold tickets = $2881
Let,
x represent the number of adult tickets sold
y represent the number of child tickets sold
According to given statement;
x+y=548 Eqn 1
6.50x+3.50y=2881 Eqn 2
Multiplying Eqn 1 by 6.50

Subtracting Eqn 2 from Eqn 3

Dividing both sides by 3

Putting y=227 in Eqn 1

Regal theater sold 321 adult tickets and 227 children tickets.

Mean = -2
Median = -1
Mode = Nil
Range = 38
Step-by-step explanation:
Given data is:
-18, 10, -20, -11, 9, 18
Arranging the data in ascending order
-20, -18, -11, 9, 10, 18
<u>Mean:</u>
Mean is given by the formula

Items are: 6

<u>Mode:</u>
Mode is the most frequent value in the data. So,
As there is no value repeated in the data. There is no mode
<u>Median:</u>
Median is the middle value of the data. As the no. of data value are even,
the average of middle 2 values is mode.
Note that the data has to be arranged in ordered to find median
Here,

<u>Range:</u>
Range is the difference between the largest and smallest value of the data
Here
Largest value = 18
Smallest value = -20
So,

Hence,
Mean = -2
Median = -1
Mode = Nil
Range = 38
