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
Answer:
Step-by-step explanation:
Just simplify 144/864 to its simplest version.
144/864, divide numerator and denominator by 144 and you get 1/6, it's simplest form.
Moving the number 6 one place to the left would put it where the 3 is, which is the thousands place
Answer:
Step-by-step explanation:
A correct answer can only be obtained from a complete question.
A rotation is not always about the origin, but in the absence of information, this will be assumed.
Rotating to the right is assumed to mean rotated from the second towards the first quadrant about the origin.
Rotating any shape about the <em>origin</em> by 360° will always return to the original (starting) position, so the final coordinates will be (-8,2) (-8,8) (-4,2).
