Answer:

21.16 m^2

Step-by-step explanation:

If the perimeter is 18.4 m, then the length of a side is 18.4 m / 4, or 4.6 m.

Then the area of the square is (4.6 m)^2, or 21.16 m^2

Find EM.<br> Can anyone help me with this?

Komok [63]

The little red dashes on the segments means they are congruent. EM = MG

Let's plug the expressions from the picture into our equation above.

7x = 8x - 6

Subtract 8x from both sides.

-x = -6

Divide both sides by -1

x = 6

EM = 7x = 7(6) = 42

The lengths of nails produced in a factory are normally distributed with a mean of 3.34 centimeters and a standard deviation of

Shtirlitz [24]

Answer:

3.47 and 3.21

Step-by-step explanation:

Let us assume the nails length be X

$X \sim N(3.34,0.07^2)$

Value let separated the top 3% is T and for bottom it would be B

$P(X < T)= 0.97$

Now converting, we get

$P(Z < \frac{T-3.34}{0.07})= 0.97$

Based on the normal standard tables, we get

$P(Z < 1.881)= 0.97$

Now compare these two above equations

$\frac{T-3.34}{0.07} = 1.881 \\\\ T = 1.881 \times 0.07 + 3.34 \\\\ = 3.47$

So for top 3% it is 3.47

Now for bottom we applied the same method as shown above

$P(Z < \frac{B-3.34}{0.07})= 0.03$

Based on the normal standard tables, we get

$P(Z < -1.881)= 0.03$

Now compare these two above equations

$\frac{B-3.34}{0.07} = -1.881$

$= -1.881 \times 0.07 + 3.34 \\\\ = 3.21$

hence, for bottom it would be 3.21
