Answer:
23a) x=-y+9/2
23b) x=1/2 y+3/2
Step-by-step explanation:
23a:
Let's solve for x.
2x+2y=9
Step 1: Add -2y to both sides.
2x+2y+−2y=9+−2y
2x=−2y+9
Step 2: Divide both sides by 2.
2x/2 = -2y+9/2
x = -y+9/2
23b:
Let's solve for x.
2x−y=3
Step 1: Add y to both sides.
2x−y+y=3+y
2x=y+3
Step 2: Divide both sides by 2.
2x/2=y+3/2
x = 1/2 y+3/2
Hope it helped!

Answer:
The probability that 6 or more women would be laid off is P=0.08.
Step-by-step explanation:
In this case, we have a group of people and a proportion of women and men. We can think of the people laid off as a random sample taken from the population (all employees of the department).
The right model to represent that is with a binomial distribution. In this case, the sample size is n=8 and the probability of picking a woman is p=0.44.
According to this model, the probability that 6 or more women, out of 8 persons, would be laid off is:
