If the number of dogs seen by the veterinarian is 40 then the number of cats seen by him will be equal to 16.
What is the ratio?
The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities in order to compare them.
As per the data given in the question,
The ratio of cats to dogs seen by veterinarian = 2:5
Number of dogs seen by veterinarian = 40
Let the number of cats seen by him be x.
Then, the ratios will be,
C : D
2 : 5
x : 40
Use cross-multiplication to find the number of cats,
5x = 2 × 40
x = (2 × 40)/5
x = 2 × 8
x = 16
To know more about Ratios:

x cats to every 40 dogs
x/40 = 2/5
(here you can cross multiply OR multiply the second fraction by 8/8)
x = 16 the vet saw 16 cats

anyway, the graph was not included. since the sleep time was included, I will assume that the circle graph is worth 24 hours
all we need to do is to convert the percentages to fractions and multiply that by 24 to find out how many hours per activity
percent means parts out of 100 so x%=x/100
so we have
School
Eating
Sleep
Homework
Free Time
School=25%
25%=25/100=1/4
1/4 times 24=6
School: 6 hours
Eating=10%
10%=10/100=1/10
1/10 times 24=2.4
Eating: 2.4 hours
Sleep=40%
40%=40/100=4/10=2/5
2/5 times 24=48/5=9.6
Sleep: 9.6 hours
Homework=10%
10%=10/100=1/10
1/10 times 24=2.4
Homework: 2.4 hours
Free Time=15%
15%=15/100=3/30
3/20 times 24=72/20=36/10=3.6
Free Time: 3.6 Hours

Answer:
The best measure of location or center is the median.
The best measure of spread or dispersion is the interquartile range (I.Q.R).
Step-by-step explanation:
The data set is skewed to the left since most of the data values fall in the upper end of the distribution. In other words the data set is negatively skewed since it is tailed to the left.
For any skewed data set;
The best measure of location or center is always the median. This is because the median is robust to outliers unlike the mean.
On the other hand, the best measure of spread or dispersion is the interquartile range (I.Q.R).
