Answer:

$P(52$

And we can find this probability with this difference:

$P(-0.851$

And if we use the normal standard distribution or excel we got:

$P(-0.851$

Step-by-step explanation:

Let X the random variable that represent the time required to construct and test a particular component of a population, and for this case we know the distribution for X is given by:

$X \sim N(60,9.4)$

Where $\mu=60$ and $\sigma=9.4$

We want to find this probability:

$P(52$

And the best way to solve this problem is using the normal standard distribution and the z score given by:

$z=\frac{x-\mu}{\sigma}$

Using this formula we got:

$P(52$

And we can find this probability with this difference:

$P(-0.851$

And if we use the normal standard distribution or excel we got:

$P(-0.851$

Write a fraction as a mixed number 20/10

Anna11 [10]

To get 20/10 as a mixed number you would have to take 20 and divide it by 10. Once you do that your answer should be 2.

Answer:

ENGLISH SYSTEM:

What you want to do is simply convert the feet into inches for 1a. and for 1b. add the inches to the length and the width. For the rest of the English system, what you have to do is plug in the numbers.

METRIC SYSTEM:

So for this one it is the same thing but different measurements. Instead of converting feet to inches, you are converting meters to centimeters. Follow the same steps as you did with the English system.

Step-by-step explanation:

1a.

13*12=156

18*12=216

1b.

156+6=162

216+9=225

162*225=36,450

3.75*8=30

36,450/30=1,215

1a.

4*100=400

5*100=500

400*500=200,000

9.5*20=190

200,000/190≈1,053
