Step-by-step explanation:

To find the constant of proportionality in the set of data apply the formula for slope where;

m= Δy/Δx

Taking values such as {3,2} and {6,4} then

m= 4-2 / 6-3

m= 2/3

I need to know number 6SP please I need to find the mean
vodka [1.7K]

The mean absolute deviation is given by the next formula:

\text{MAD}=\frac{1}{n}\sum ^{\square}_i|x_i-\bar{x}|

Where n is the number of points in the data set and x with a bar on top is the mean.

In our case,

\bar{x}=\frac{1}{25}(5\cdot1+5\cdot2+4\cdot3+4\cdot4+6\cdot5+6\cdot1)=\frac{79}{25}

and n=25.

Then,

\text{MAD}=\frac{1}{25}(5|1-\frac{79}{25}|+5|2-\frac{79}{25}|+4|3-\frac{79}{25}|+4|4-\frac{79}{25}|+6|5-\frac{79}{25}|+|6-\frac{79}{25}|)

Finally,

\text{MAD}=\frac{862}{625}\approx1.4

The answer is 1.4 once rounded.

24 - 4 x 2 + 4b = 20 - 16​
AnnZ [28]

Answer:

b = -3

Step-by-step explanation:

Solve for b:

4 b - 4 2 + 24 = 20 - 16

-4×2 = -8:

4 b + -8 + 24 = 20 - 16

Grouping like terms, 4 b - 8 + 24 = 4 b + (24 - 8):

4 b + (24 - 8) = 20 - 16

24 - 8 = 16:

4 b + 16 = 20 - 16

20 - 16 = 4:

4 b + 16 = 4

Subtract 16 from both sides:

4 b + (16 - 16) = 4 - 16

16 - 16 = 0:

4 b = 4 - 16

4 - 16 = -12:

4 b = -12

Divide both sides of 4 b = -12 by 4:

(4 b)/4 = (-12)/4

4/4 = 1:

b = (-12)/4

The gcd of -12 and 4 is 4, so (-12)/4 = (4 (-3))/(4×1) = 4/4×-3 = -3:

Answer: b = -3
