Answer:
f(g(3)) = 15
Step-by-step explanation:
g(x)=1+x^2
g(3) = 1 + 3^2 = 1 + 9 = 10
f(g(3)) = 2(10) - 5 = 20 - 5 = 15
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
