A family has two cats named Gordo and Flaco. Gordo weighs 15 pounds and Flaco weighs 8 pounds. A cat’s weight is classified as u
Elena-2011 [213]

Answer:

Gordo's weight = 15 pounds

It is outside the healthy weight range and is in the top 5% of weights of cats.

Gordo's weight makes Gordo unhealthy.

Step-by-step explanation:

μ = mean weight = 9.5 pounds

σ = standard deviation = 1.5 pounds

This is a normal distribution problem

We first calculate the limit of the bottom 5% of weights

Let the z-score for this limit be z'

P(z < z') = 0.05

From the normal distribution table,

z' = -1.645

And the limit for the top 5% which is z" = 1.645.

The weight that corresponds to these scores are then calculated.

Standardized scores are given as

z = (x - μ)/σ

So,

z' = (limit for the bottom 5% - μ)/σ

-1.645 = (limit for the bottom 5% - 9.5)/1.5

limit of the bottom 5% = (-1.645)(1.5) + 9.5 = 7.033 pounds

z" = ( (limit for the top 5% - μ)/σ

1.645 = (limit for the top 5% - 9.5)/1.5

limit of the bottom 5% = (1.645)(1.5) + 9.5 = 11.968 pounds

Therefore the healthy weight range for cats is (7.033 < x < 9.968)

Gordo's weight = 15 pounds

It is outside the healthy weight range and is in the top 5% of weights of cats.

Gordo's weight makes the cat unhealthy.

Flaco's weight = 8 pounds

Flaco's weight lies in the healthy weight range for cats. Hence, Flaco is a healthy cat.

Some of these, I don't know how to answer. I can only give the answers to the ones I do know how to do.


16. 24 plants can be watered with this can.

Equation & Answer:

134.4 ÷ 5.6 = 24


17. 32 miniature bottles can be made from the large bottle of ketchup.

Equation & Answer:

198.4 ÷ 6.2 = 32


20. -3 + -8 = -11


-3 + 8 = 5


3 + -8 = -5


-9 + 4 = -5


-6 + -1 = -7


-8 + 9 = 1


Negatives plus negatives:

When there are two negative numbers together and the equation has + sign in it, the + sign changes to be a - sign.


21. 42 + -56 = -14


22. -49 + -17 = -66


Hope this helped in some way,
