What is quartile 1 (Q1)quartile 3 (Q3) and the IQR? Answer all three parts . 13, 23, 24, 25, 26, 26, 37, 47, 47, 48, 50

Fittoniya [83]

Answer:

Quartile 1 (Q1) = 24

Quartile 2 (Q2) = 47

IQR = 23

Step-by-step explanation:

Given:

The set of data are:

13, 23, 24, 25, 26, 26, 37, 47, 47, 48, 50

The data are in increasing order. The number terms are, $n = 11$ .

Therefore, the middle term = $\frac{n+1}{2}=\frac{11+1}{2}=6^{th}\ term$

So, the median = 26

Now, the median divides the set of data into two parts. The median of first part is the quartile 1 and the median of second part is quartile 2.

So, the first part has the following terms:

13, 23, 24, 25, 26

Here also, $n=5$ . So, the third term is the median.

∴ Q1 = 24

The second part has the following terms:

37, 47, 47, 48, 50

Here also, $n=5$ . So, the third term is the median.

∴ Q2 = 47.

Now, IQR = Q2 - Q1 = 47 - 24 = 23.

100 points.... The graph below is a solution to what system of linear inequalities?

fomenos

Answer:

The system of linear inequalities is

$y\geq x+1$

$y>-x-2$

Step-by-step explanation:

From the given graph it is noticed that we have two lines one is solid and second is dashed.

The solid line passing through the points (0,1) and (-1,0). The dashed line passing through the points (0,-2) and (-2,0).

If line passing through two points, then the equation of line is

$y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The related equation of solid line is

$y-1=\frac{0-1}{-1-0}(x-0)$

$y=x+1$

Similarly the related equation of dashed line is

$y-(-2)=\frac{0-(-2)}{-2-0}(x-0)$

$y=-x-2$

From the given figure it is noticed that the point (0,2) is in the shaded region, it means the point (0,2) will satisfy the inequalities.

$2=0+1$

$2=1$

This statement will true if the sign of inequality is $\geq$ because It is a solid line.

$2=-0-2$

$2=-2$

This statement will true if the sign of inequality is > because It is a dashed line.

The system of linear inequalities is

$y\geq x+1$

$y>-x-2$
