What is the mean absolute deviation of the data set? {12, 4, 30, 16, 18}
LiRa [457]
12 + 4 + 30 + 16 + 18 = 80
80 ÷ 5 = 16

16-12=4
16-4=12
30-16=14
16-16=0
18-16=2

4 + 12 + 14 + 0 + 2= 32
32 ÷ 5 is 6.4

Consider the line 7x+4y= 3. What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this
kirza4 [7]

Answer:

1) -7/4

2) 4/7

3) -1/5

Step-by-step explanation:

1) A parallel line would have the same gradient so:

4y = -7x +3
y =\frac{-7}{4}x  +\frac{3}{4}

So a parallel line would have the gradient of \frac{-7}{4}.

2) A perpendicular line would have the inverse reciprocal of the gradient so multiplying the 2 gradients would equal -1 so:

Initially Gradient = -7/4

-7/4 x Perpendicular line = -1

Perpendicular line = -1 x 4/-7

Perpendicular line = 4/7

3) Using the same principle, the perpendicular gradient would be -1/5x
