Answer:

This is khan academy. I am pretty sure they have a video for this but whatever.

Step-by-step explanation:

So we are using sin, cosine, and tan. 3.4 is the hypotenuse. the side is X. The angle is 20 degrees. So, this is adjacent to hypotenuse. This means it is cosine.

3.4cos(20)= around 3.19

And thats that! let me know if this is wrong and I will try to fix it.

The population of lengths of aluminum-coated steel sheets is normally distributed with a mean of 30.05 inches and a standard dev
Blababa [14]

Answer:

0.3707

Step-by-step explanation:

Mean length = 30.05 inches

Standard deviation = 0.3 inches

We are supposed to find the probability that the average length of a steel sheet from a sample of 9 units is more than 29.95 inches long

Formula : Z=\frac{x-\mu}{\sigma}

\mu = 30.05\\\sigma = 0.3

x= 29.95

Substitute the values :

Z=\frac{29.95-30.05}{0.3}

Z=-0.33

Refer the z table for p value

p value = 0.3707

So, the probability that the average length of a steel sheet from a sample of 9 units is more than 29.95 inches long is 0.3707

I don’t get how to do it please help????
bonufazy [111]

To put this into simpler terms, well simplier for me anyways, Emma is dividing 9 inches of paper into 2/5, or .4, inches of paper.

That being said, we now just need to divide 9 by 2/5 or .4

We get 22.5

So Emma will be able to make 22 strips since we can't have half a strip. (Well, we could, but it would be small than what we need)


Any questions?
