Answer:
yes it is (2,-3)
Step-by-step explanation:
if you see in there where both of the lines intersect or touch each other (the gray dot)
the point of intersect is at (2, -3)
Answer:
a.
Step-by-step explanation:
Carmen simplifies the expression and gets the coefficient of y is 10. Thus, the correct option is C.
<h3>What is simplification?</h3>
Simplification is to make something easier to do or understand and to make something less complicated.
Given
Carmen simplifies the expression
.
We can add x term with x, y term with y, and constant with constant.
On simplifying, we have

Thus, the coefficeint of y is 10.

Answer:
a) 0.7225
b) 0.5220
c) 0.478
It is not unusual.
Step-by-step explanation:
Probability grocery bags are plastic = 85% = 0.85
a) If two grocery bags are chosen at random, the probability that both grocery bags are plastic would be:
b) If four bags are chosen at random, the probability that all are plastic:
Probability all four bags chosen randomly are plastic bags is 0.5220
c) The probability that at least one of four randomly selected grocery bags is paper:
Let's first check for the probability of getting a paper bag.
P(paper bag) = 1 - 0.85 = 0.15
Probability of getting a paper bag is 0.15
Probability that at least one of four randomly selected grocery bags is paper would be:

Since the probability that at least one bag is paper, 0.478 is greater than 0.05, it is not unusual.
