Answer:

270ft^2

Step-by-step explanation:

we need to multiply the terms given

15feet*18feet

we know feet*feet= $feet^{2}$

=ft^2

and

15*18=270

finally we have

270 $feet^{2}$

=270ft^2

Answer:

270 ft^2

Step-by-step explanation:

you are trying to find the area so you multiple 15 times 18 which is 270. Then feet times feet is feet squared. so you get 270 square feet.

Suppose that the weights of 5400 registered female Labrador retrievers in the United States are distributed normally with a mean

Maurinko [17]

Answer:

$N= 4543$ Labrador retrievers

Step-by-step explanation:

We know that the mean $\mu$ is:

$\mu = 62.5$

and the standard deviation $\sigma$ is:

$\sigma=2.5$

The probability that a randomly selected Labrador retriever weighs less than 65 pounds is:

$P(X$

We calculate the Z-score for X =65

$Z = \frac{X-\mu}{\sigma}\\\\Z =\frac{65-62.5}{65}=1$

$P(X$

Looking in the table for the standard normal distribution we have to:

$P(Z$ .

Finally the amount N of Labrador retrievers that weigh less than 65 pounds is:

$N = P(X$

$N = 0.8413*5400$

$N= 4543$ Labrador retrievers
