Answer:
D.
Step-by-step explanation:
f(x) =
g(x) = 2x + 3
(x) = 'f' divided by 'g'
Substitute.
x cannot be - because that would create a zero in the denominator.
That's a no-no.
It makes it 'undefined'

Answer:
see below
Step-by-step explanation:
a)
minimum = 45
first quartile = 55
median = 75
third quartile = 85
maximum = 95
lower fence = Q1 - 1.5 x IQR = 10
upper fence = Q3 + 1.5 x IQR = 130
Therefore, one outlier = 140
b) mean = sum of all numbers ÷ n = 760 ÷ 10 = 76 ($76,000)
There is an outlier (140). Outliers don't affect the median as much as they affect the mean.
c) see attached
d) negative skew
