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.
Answer:
it have no answer in real number(but it have in complex number if you know)
Step-by-step explanation:
4x^2+36=0
4x^2=-36
(if you know complex numbers see this: x^2=-9 then
)
Answer:
3/4 + 0 = 3/4 Additive Neutral Property
Step-by-step explanation:
Answer:
x = 0, 4/5
Step-by-step explanation:
The zero-product property states that if the product of a and b is zero, then either a = 0, b = 0, or both terms equal zero
- Here our a term is -x and our b term is (5x - 4)
- Setting each term equal to zero and solving for x we get
- -x = 0 → x = 0
- 5x - 4 = 0 → 5x = 4 → x = 4/5
