navik [9.2K]
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

110 ÷ 5=22

Now multiply 2 and 22

2*22=44

Now multiply 3 and 22

3*22=66

The ratio is 44:66 

Answer: There are 44 puppies

A manufacturer knows that their items have a normally distributed length, with a mean of 13.2 inches, and standard deviation of
Lana71 [14]

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 ..
