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%

Answer:
The ratio of candidate 2's votes to candidate 1's votes was 24:8
The ratio of candidate 1's votes to candidate 2's votes was 1:3
Step-by-step explanation:
Candidate 1's votes is 8000
Candidate 2's votes 24000
To get the ratio of candidate 2's votes to candidate 1's votes take 24000 : 8000 divide by 1000 both sides you get 24:8
To get the ratio of candidate 1's votes to candidate 2's votes take 8000 : 24000 divide 8000 both sides you get 1:3
Other ratios whatever you divide the answers is incorrect
