Answer:

IQR = 7

Step-by-step explanation:

To get the interquartile range of the set of data, the following steps must be followed:

Datas 4, 4, 6 , 7, 10 , 11 , 12, 14 ,15

Step 1: Rearrange the datas in ascending or descending order if not arranged.

4, 4, 6 7, 10, 11, 12, 14, 15

Step 2:

We will locate the (N+1/4)the cumulative value of the data where N is the total frequency of the data.

N = 4 + 4 + 6 + 7 + 10 + 11 + 12 + 14 + 15

N = 83

N+1/4 = 83+1/4

= 84/4

= 21st cumulative value

On cumulating the values up to the 21st value or more:

4 + 4 + 6 + 7

= 21

Since the 21st value falls on 7, then the interquartile range of the set of data is 7

Which lines are parellele

natali 33 [55]

Line 1 and Line 4 are parallel lines

Solution:

General equation of a line:

y = mx + c

where m is the slope and c is the y-intercept of the line.

<u>To find the slope of each line:</u>

Line 1: $y=-\frac{3}{4} x-6$

Slope $(m_1)=-\frac{3}{4}$

Line 2: $y-7=-4(x+9)$

$y-7=-4x-36$

Add 7 on both sides, we get

$y=-4x-29$

Slope $(m_2)=-4$

Line 3: $y=-2 x+6$

Slope $(m_3)=-2$

Line 4: $x+\frac{4}{3} y=-5$

Subtract x from both sides, we get

$\frac{4}{3} y=-x-5$

Multiply by $\frac{3}{4}$ on both sides, we get

$y=-\frac{3}{4}x-\frac{15}{4}$

Slope $(m_4)=-\frac{3}{4}$

<em>Two lines are parallel, if their slopes are equal.</em>

From the above slopes,

$m_1=m_4$

Therefore Line 1 and Line 4 are parallel lines.
