B, I took this test recently and got it right
Question: You have 110 dogs (which is the total amount of dogs/pups) and the ratio of the puppies is 2:3. How many puppies are there?
Add 2 and 3 which adds to 5 (You need to combine all the "pie pieces")
Now, divide 110 by 5

÷

Now multiply 2 and 22

Now multiply 3 and 22

The ratio is 44:66

Answer:
0.5358
Step-by-step explanation:
Given
mean = μ = 13.2 inches
and
SD = σ = 2.2 inches
We have to find z-score for the given value 13.4 first
z-score = (x-μ)/σ
= (13.4-13.2)/2.2
=0.2/2.2
=0.0909
We have to find the area to the left of given z-score
The area to the left is 0.5358
So, the probability of choosing an item with length less than 13.4 is 0.5358 ..
