exhibit population for ten integers is 15,19,19,20,20,20,21,22,22,22 mean is 20 variance is 4
Step-by-step explanation:
- Mean is helps in finding the mid point of the data.
- Variance is the variability of data it was here.
- In order to get the data straight the combination of 4 was required.
- 4 is variance one data set was 19 other had to be 22.
- As mean is 20 three means had to be 20.
- from mean 20 4 is greater then 20 and 3 is less then 20.
- 15 being the lowest it compensated the variance to 4.
- Mathematically there are many ways to do this using function.
- This is to be found out at a traditional method.
- Reducing or increase the number as it was integers.
Answer:
Step-by-step explanation:
(a)
The domain of a function denotes the upper and lower limits of the x co-ordinate values, over which the function is defined.
Here, the x co-ordinates over which the function is defined are from -9 to 7.
Hence ,the domain is: -9 ≤ x ≤ 7
(b)
The range of a function denotes the upper and lower limits of the y co-ordinate values, which the function gives.
Here, the y co-ordinates over which the function gives are from -6 to 4.
Hence ,the domain is: -6 ≤ y ≤ 4
