Answer:
Number of student tickets = 325
Number of adult tickets = 404
Step-by-step explanation:
Let,
x be the number of student tickets
y be the number of adult tickets
According to given statement;
x+y=729 Eqn 1
3x+5y=2995 Eqn 2
Multiplying Eqn 1 by 3
3(x+y=729)
3x+3y=2187 Eqn 3
Subtracting Eqn 3 from Eqn 2
(3x+5y)-(3x+3y)=2995-2187
3x+5y-3x-3y=808
2y=808
Dividing both sides by 2
Putting y=404 in Eqn 1
x+404=729
x=729-404
x=325
Hence,
Number of student tickets = 325
Number of adult tickets = 404
<h3>The 2
answers are: A and D</h3>
==========================================
Explanations
A. True. This is because there are 13 dots shown. You cannot use the box plot to determine this.
B. False. This contradicts choice A above. Also, we cannot use the box plot to determine how many people there are. What 12-7 = 5 is showing is that the range is 5. This means the range for the age of runners is 5 years. In other words, 5 years is the span from the youngest (age 7) to the oldest (age 12).
C. False. The median is 10 as its shown in the box plot. Recall the median for any box and whisker plot is the vertical line inside the box.
D. True. The vertical line inside the box is the median. This vertical line does not have to be exactly halfway between the left and right edges of the box.
E. False. A box plot can be used to determine variability (in terms of range and IQR). You can determine the variability from a dot plot, though you'll have to do a bit of work to get it.
F. False. Refer to choice E.
