Answer:
Step-by-step explanation:
Given : Number of good laptops =20
Number of defective ones=3
Total laptops =23
If 2 laptops were selected, then the probability that none of them was defective would be =
The probability that at least one will be defective= 1- P(none of them is defective)
Hence, the probability that at least one will be defective.
Answer: The last option, Stacy is incorrect because she should multiply 2 and 2 first and then subtract 4 from 12.

Top left Equation:
Step-by-step explanation:
You start at 2/3, or the left side.
Since the line is directing left, you are subtracting, or adding a negative.
If you see, you are moving 7 - 1/3s to the left
7 x 1/3 = 7 / 3
7 / 3 = 2 1/3
And 2/3 + (-2 1/3) = -1 2/3

Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have the slope m = -1/5. Substitute:
Put the coordinates of the given point (-3, 7) to the equation:
<em>subtract 3/5 from both sides</em>
