Answer:
6.7% of employees at Solar Systems, Inc. are younger than 30 years old
Step-by-step explanation:
The mean of ages of the employees at Solar Systems is 32.7 years
Mean = 
Standard deviation =
We are supposed to find What percentage of employees at Solar Systems, Inc. are younger than 30 years old i.e.P(x<30)
So,

Z=-1.5
Refer the z table for p value
So,p value = 0.0668
So P(x<30)=0.0668= 6.68% = 6.7%
So, 6.7% of employees at Solar Systems, Inc. are younger than 30 years old

Answer:
The value of 'x' is 31 unit
Step-by-step explanation:
Given:
Measure of each side = 
Perimeter of sails = 63 units.
We need to find the value of x.
Solution:
Now we can see that from given data.
A sailboat's Saul has three sides.
Now assuming it to be triangle we get;
"Perimeter of triangle is equal to sum of all side."
So we can say that;

Now adding both side by 30 we get;

Now dividing both side by 3 we get;

Hence the value of 'x' is 31 units.
Hi there!
Looks like a lot of work is going on here.
Let's start by solving this equation for the x.

Step 1) Add -20y to both sides.

Step 2) Divide both sides by 5.


Final Answer:

Now, let's solve for y.
Step 1) Add -5x to both sides.

Step 2) Divide both sides by 20.


Final Answer:

Hope this helps! :D
Hint - When you have two variables in an equation, and you want to solve for one, the other will end up in your answer. :)
