Anybody knows what is -2(g - 3) = 2(g - 7)

Veronika [31]

Answer:

g = 4.6

Step-by-step explanation:

-3(g - 3) = 2(g - 7)

-3g + 9 = 2g - 14

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

Monica has a 24-inch square frame. There are 4 equal sides. She paints 3/4 of one side of the frame blue. What fraction of the f

IgorC [24]

Answer:

3/16

Step-by-step explanation:

Monica has a 24-inch square frame.

There are 4 equal sides.

Hence, length of each side=24/4 inch

= 6 inch

She paints 3/4 of one side of the frame blue.

i.e. she paints $\dfrac{3}{4}\times 6$ inch

Total part to be painted=24 inch

Hence, fraction of the frame Monica painted blue is:

$\dfrac{3\times 6}{4\times 24}\\ \\= \dfrac{3}{16}$

Vsevolod [243]

Answer:

The result is

$\frac{5}{2}$

2.5

Step-by-step explanation:

We want to simplify

$\frac{5}{8} \times 4$

We know that 4 goes into 8 twice.

This implies that:

$\frac{5}{8} \times 4 = \frac{5}{2}$

We can convert the result into decimals as follows:

$\frac{5}{2} = \frac{25}{10} = 2.5$
