Answer:
130 ; 50% ; 25%
Step-by-step explanation:
Using te boxplot to answer the underlying questions :
Number of employees who spend $10 or less corresponds to the lower quartile, which is up to 25% of the distribution :
Total number of employees = 520
Number of employees who spend $10 or less = 25% of 520 = 0.25 * 520 = 130 employees.
Percentage of employees who spend from $10 to $45 = Interquartile range
$10 corresponds to lower quartile = 25%
$45 corresponds to upper quartile = 75%
IQR = 75% - 25% = 50%
Percentage who spend $45 or more
$45 corresponds to the upper QUARTILE (Q3) :
45 or more = 100% - Q3 = 100% - 75% = 25%
<h2><u>
Boys and girls</u></h2>

As there are 3 boys and 2 girls in the group, only 1 game was played between a girl and a girl.
Since a group of friends played chess, and each person played exactly one game with each other in the group, and out of the total number of games played, 3 games were played between a boy and a boy, and 6 games were between a boy and a girl, to determine how many games were played between a girl and a girl, the following calculation must be performed:
- 2 players = 1 match
- 3 players = 3 games
- 6/3 = 2
Therefore, as there are 3 boys and 2 girls in the group, only 1 game was played between a girl and a girl.

X^2 - x - 12
Hope this helps!
Y = x + 1......slope = 1, y int = 1
y = x + 2.....slope = 1, y int = 2
In y = mx + b form, the slope can be found in the m position and the y int can be found in the b position.
if the equations have the same slope, but different y int, then u have a set of parallel lines which never cross...therefore they have no solution and are inconsistent
