Answer: 2 hours and 28 minutes
Equation: 48+25 = 72+75 = 148 min
The correct answer is 3.8
Answer:
Step-by-step explanation:
y - 3 = -(x + 2)
y - 3 = -x - 2
y = -x + 1
Solution:
As, two set of data are each symmetrical and do not contain outliers.
To find the center , the best way is to find Median of data set.Median of Data set is the mid value of Data that is center of Data.
As, you have to find variability , mean can't measure variability. Mean deviation would have been better option.
So, MAD=Median absolute Deviation , would be better tool to measure variability. Because it is Absolute difference between median and Each value of data set.
So, Option (C) median and MAD, would be best way to compare the two given data set.
Two angles are said to be supplementary if their sum is 180 degrees. So, if x and y are supplementary angles, the formula is
![x + y = 180](https://tex.z-dn.net/?f=%20x%20%2B%20y%20%3D%20180%20)
We know that one of the angles (say x) is 98. So, the equation updates to
![98 + y = 180](https://tex.z-dn.net/?f=%2098%20%2B%20y%20%3D%20180%20)
If we want to solve for the other angle, we can simply subtract 98 from both sides to get
![y = 180-98 = 82](https://tex.z-dn.net/?f=%20y%20%3D%20180-98%20%3D%2082%20)
