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

So

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

Solve for A.................<br><br> H= A/2
grigory [225]

Step-by-step explanation:

First, multiply each side of the equation by

2

to eliminate the fraction while keeping the equation balanced:

2×A=2×h2(a+b)

2A=2×h2(a+b)

2A=h(a+b)

Now, divide each side of the equation by

a

+

b

to solve for

h

while keeping the equation balanced:

2Aa+b=h(a+b)a+b

2Aa+b=h(a+b)a+b

2Aa+b=h

h=2Aa+b
