Answer:
Option a) Mean
Mean is affected a lot by the change in the last observation as the median remains the same.
Step-by-step explanation:
we are given the following in the question:
Data set A: 64, 65, 66, 68, 70, 71, 72
Data set B: 64, 65, 66, 68, 70, 71, 720
For data set A, the mean and median are 68.
For data set B:
Formula:
Sorted data:
64, 65, 66, 68, 70, 71, 720
Clearly, 720 is the is a outlier.
As seen mean is affected a lot by the change in the last observation as the median remains the same.

<h2>
The circle (x − 7)² + (y − 8)² = 9 is a circle with center (7,8) and radius is 3</h2>
Step-by-step explanation:
Equation of circle with (h,k) as center and radius r is given by,
(x-h)²+(y-k)² = r²
Here we need to describe the circle given by the equation (x − 7)² + (y − 8)² = 9
Changing equation to (x-h)²+(y-k)² = r² form
(x − 7)² + (y − 8)² = 9
(x − 7)² + (y − 8)² = 3²
So, h = 7 , k = 8 and r = 3
Center is (7,8) and radius is 3
The circle (x − 7)² + (y − 8)² = 9 is a circle with center (7,8) and radius is 3
Answer:
The surface area is 91
Step-by-step explanation:
3*4=12
12/2=6
6*2=12
7*5=30
4*7=28
3*7=21
12+30+28+21=91
The equations that are on the left are caculations triangle calcuations. The equations on the right are the ones that equal each of the 2d shapes in the prism and if u add them all up you get your surface area.
Answer:
h=55.4 mm
Step-by-step explanation:
Area of a triangle = 
where b is base and h is height
now just plug and chug
227.14 = 8.2h/2
227.14=4.1h
h=227.14/4.1
h=55.4
check answer:
55.4 * 8.2 /2 = 227.14, as proven by my calculator
