Answer:
x> -7/3y -7
Step-by-step explanation: -7y-3x<21
Step 1: Add 7y to both sides.
−3x−7y+7y<21+7y
−3x<7y+21
Step 2: Divide both sides by -3.
-3x/-3 < 7y+21/-3
x>-7/3y -7
-13/24 because u have to multiply to get the same denominator which would end up being -15/24 and 2/24 add that to get -13/24

And we can find this probability using the normal standard table with this difference:
Step-by-step explanation:
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And we can solve the problem using the z score formula given by:
Using this formula we got:
And we can find this probability using the normal standard table with this difference:
