Answer:
the index of 2 is -1
Step-by-step explanation:

Find the mean for both:
Sierra: 2 + 11 + 12 + 13 + 15 = 53
53/5 =10.6
Median is the middle value = 12
Alek: 9 + 11 + 11 + 12 + 13 = 56
56/5 = 11.2
Median = 11
A: The medians do not equal the mean.
B: Sierra's are more spread out, ( no identical ages and a greater range ).
C: Sierra's mean is less than Alek.
D. Sierra has an outlier (2).
The answer would be B
Answer:
???????
Step-by-step explanation:
Answer:
which pair of numbers has a product of ac and a sum of b
ac = (-5)(-3)
sum = -8
x^2 - 5x - 3x + 15
x(x-5)-3(x-5)
(x-3) (x-5)
x=3 x=5
what is the factored form of the trinomial = (x - 3) (x - 5)
2. Factor the following:
x^2 - 8 x + 15
The factors of 15 that sum to -8 are -3 and -5. So, x^2 - 8 x + 15 = (x - 3) (x - 5):
Answer: (x - 3) (x - 5)
