Answer:

d + 23 = 69

d = 46

Step-by-step explanation:

Write y=1/8x+7 in standard form using intergers
lakkis [162]

Answer:

B) -x+8y=56

Step-by-step explanation:

y=1/8x+7

Multiply by 8 to clear the fraction

8y = 8(1/8x+7)

Distribute

8y = 8*1/8x +8*7

8y = x+56

Subtract x from each side

-x+8y = x-x+56

-x+8y = 56

Rewrite the following equation in slope-intercept form.
dexar [7]

Answer:

Slope-intercept form is

y = mx + b

We want to get the y by itself on one side of the equation.

0 = 18x + 6y – 2

First let's subtract 6y from both sides.

-6y = 18x – 2

Next let's divide both sides by -6.

y = (18 / -6)x - (2 / -6)

y = -3x + 1/3

...The last instructions are kind of confusing to me, but I think that is the answer you're after. :)

Can someone show me how to do Mean absolute deviation
morpeh [17]
To find the mean of a set, add up all of the numbers and divide by how many numbers you have. For the first set:
\mu=\frac{10.7+2.4}2=\frac{13.1}2=6.55
For the second set:
\mu=\frac{13.7+2.5}2=\frac{16.2}2=8.1

To find the mean absolute deviation, (MAD) find the mean of the distances of each number from the mean.
For the first set: 
MAD=\frac{|10.7-6.55|+|2.4-6.55|}2=\frac{4.15+4.15}2=\frac{8.3}2=4.15
For the second set:
MAD=\frac{|13.7-8.1|+|2.5-8.1|}2=\frac{5.6+5.6}2=\frac{11.2}2=5.6
Note that when you only have two data points the mean is directly between them, which is why the distances are the same.

The means-to-MAD ratio is simply that, divide one by the other and that's it.
For the first set:
6.55\div4.15=1.57831325
For the second set:
8.1\div5.6=1.44642857
