Problem #1. <span>c. (-1/2,-5/2),(2,5)
#3 x^2 -18x +81 = 19+81 (18/2)^2
(x-9)^2 = 100
x-9 = + or - square root of 100
x= 9 + or - 10
x= 19 and -1

<span>A: The middle 95% contain between 23.8 and 24.2 oz.(2 SDs under and over the mean)
B: Approximately 68% of boxes have between 23.9 and 24.1 oz of cereal (1 SD under and over the mean)
C: 2.5% of boxes contain more than 24.2, because 95% are within 2 SDs, and that includes lower and higher extremes.
D: 16% of boxes have more than 24.1, because 68% are within 1 SD of the mean, so 32 are left, and that includes lower and higher extremes.</span>

Answer:
By month 10 both buyers will have paid the same amount of 3,000.
Step-by-step explanation:
The equation would be 500 + 250m = 300m. If you put 10 in for m you get the same amount on both sides of the equation.
500 + 250m = 300m
500 + 250(10) = 300(10)
500 + 2,500 = 300(10)
3,000 = 300(10)
3,000 = 3,000
