Answer:
97.8%
Step-by-step explanation:
110 is 2 standard deviations above the mean (6+6 = 12)
12+98 = 110
Looking at the standard deviation curve
P(x< or = to 110) = 1 - P(x>110)
We can find the probability that x>100 by adding anything above 2 standard deviations above the curve.
P(x>110) = 2.1+.1 = 2.2%
P(x< or = to 110) = 1 - P(x>110)
= 1- 2.2%
= 1- .022
= .978
= 97.8 %
Answer:
3,3
11x, 2x, 2x, 5x, 11x
Step-by-step explanation:
3 and 3 are like terms and all the numbers with x in front of them are like terms.
Answer:
x^2 -17x+72
Step-by-step explanation:
(x – 8) (x – 9)
FOIL
first x*x =x^2
outer -9*x = -9x
inner -8*x = -8x
last = -9*-8 = 72
Add them together
x^2 -9x-8x+72
x^2 -17x+72
