Answer:
The variance of the given data is 106.9667
Step-by-step explanation:
The variance, S² of a sample is given by the expression;
Where:
= One of the observations
= The mean of the observations
n = Number in the sample = 6
The mean = Σ/n = (26 + 32 + 29 + 16 + 45 + 19
)/6 = 167/6 = 27.833
Therefore, we have;
S² = ((26 - 27.833)²+(32 - 27.833)²+(29 - 27.833)²+(16 - 27.833)²+(45 - 27.833)²+(19 - 27.833)²)/(6 - 1) = 106.9667.
Answer:
All real numbers greater than or equal to -1 and less than or equal to 2
Step-by-step explanation:
Let
A_1 ------> the area of rectangle
A_2 ----> the area of triangle
we know that
<em>Find out the area of rectangle</em>
<em>Find out the area of triangle</em>
substitute
Simplify
<em>First case (positive value)</em>
<em>Second case (negative value)</em>
Multiply by -1 both sides
therefore
The solution for x is the interval -----> [-1,2]
All real numbers greater than or equal to -1 and less than or equal to 2
