I will mark brainliest if u answer

Step-by-step explanation:

The trick here is finding the scale used in the plotting. From the question, we can find two hints;

- Number of cat = 40. Since it has an equal scale for both men and women. It means the 40 / 2 = 20 (20 men and 20 women) has cat as their favorite pet.

- Since we know that the number of men is 20, we have to find what individual box represents. There are 4 boxes, this means each box would have  a value of 20 / 4 = 5

Dog

For men, there are basically 5 lines (or boxes, if you prefer). This means 5 * 5 = 25

For women, there are basically 6 lines (or boxes, if you prefer). This means 6 * 5 = 30

Total frequency = 30 + 25 = 55

Hamster

For men, there are basically 3 lines (or boxes, if you prefer). This means 3 * 5 = 15

For women, there is basically 1 line (or box, if you prefer). This means 1 * 5 = 5

Total frequency = 15 + 5 = 20

Other

For men, there are basically 2 lines (or boxes, if you prefer). This means 2 * 5 = 10

For women, there are basically 3 lines (or boxes, if you prefer). This means 3 * 5 = 15

Total frequency = 10 + 15 = 25
