Answer:
non linear im pretty sure
So for this, I will be using the elimination method. So firstly, multiply both sides of the first equation by 2 and both sides of the second equation by 3:
Now add the two equations to get . From here you can solve for x. For this, just divide both sides by 17, and your first answer will be
Now that we have the value of x, substitute it into either equation to solve for y:
<h3><u>In short, x = 5 and y = -2.</u></h3>
Answer:
And we can find the probability with this difference and using the normal standard table:
Step-by-step explanation:
Let X the random variable that represent the wages, and for this case we know the distribution for X is given by:
Where and
We want to find this probability:
And we can use the z score formula given by:
Using this formula we have:
And we can find the probability with this difference and using the normal standard table:
