Write the equation of the line that passes through the points (2 , -1) and has a slope of - 3​
svetlana [45]

Answer:

y=-3x+5

Step-by-step explanation:

y=mx+b

m=slope or gradient (=-3)

y=-3x+b  

Add your points

(2, -1)

-1=(-3 x 2)+b

-1= -6+b

-1+6=b

b=5

y=-3x+5

Jesse asked how many magazine subscriptions each
torisob [31]

Answer:

Interquartile range of the data is:

IQR = 2

Step-by-step explanation:

First lets rearrange the data in ascending order:

0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 3, 4, 4

<h3>Find Median:</h3>

Median = (No. of terms +1) / 2      (when n = odd number)

Median = 14/2 (th term)

Median = 7th term

Median = 1

<h3>Find Upper and Lower Medians:</h3>

As the number of total terms is odd (n=13) , we omit the median and form upper and lower sets and find their medium

0, 0, 0, 1, 1, 1, 1, 2, 2, 2, 3, 4, 4

Remove the median

0, 0, 0, 1, 1, 1    |    2, 2, 2, 3, 4, 4

Calculate the median of lower portion

0, 0, 0, 1, 1, 1

For even numbers

Lower Median = (0+1)/2

Lower Median = 0.5

Calculate the median of upper portion

2, 2, 2, 3, 4, 4

Upper Median = (2+3)/2

Upper Median = 2.5

<h3>Interquartile Range:</h3>

It is the difference between Upper and Lower Median

IQR = 2.5 - 0.5

IQR = 2
