Answer:

\bar X = 100.4

And we can calculate the deviations from each value like this:

|101.5-100.4 |=1.1

|98.7-100.4 |=1.7

|95.4-100.4 |=5.0

|92.3-100.4 |=8.1

|109.8-100.4 |=9.4

|104.7-100.4|=4.3

And the mean absolute deviation would be:

MAD =\frac{1.1+1.7+5.0+8.1+9.4+4.3}{6}= 4.93

Step-by-step explanation:

For this case we have the following dataset given:

101.5 98.7 95.4 92.3 109.8 104.7

We can calculate the mean with the following formula:

\bar X =\frac{\sum_{i=1}^n X_i}{n}

And replacing we got:

\bar X = 100.4

And we can calculate the deviations from each value like this:

|101.5-100.4 |=1.1

|98.7-100.4 |=1.7

|95.4-100.4 |=5.0

|92.3-100.4 |=8.1

|109.8-100.4 |=9.4

|104.7-100.4|=4.3

And the mean absolute deviation would be:

MAD =\frac{1.1+1.7+5.0+8.1+9.4+4.3}{6}= 4.93

Please find the X and Y plot points!! (I’ll give brainliest: x+2y=10 -x+y=2
vova2212 [387]

Step-by-step explanation:

x+2y = 10 ...1

-x+y = 2 ...2

...1 + ...2

x+2y+(-x+y) = 10 + 2

3y = 12

y = 12/3

= 4

Replace y = 4 in ...1

x + 2(4) = 10

x + 8 = 10

x = 10 - 8

= 2

(x,y) = (2,4)

How do you solve this system by elimination?
zimovet [89]
(-5x+7y=11) - (-5x+3y=19) =
4y = -8. (divide both sides by 4)

y = -2

Substitute

-5x + 7(-2) =11
-5x - 14 =11
-5x = 25

x = -5



y = -2 and x = -5

2x divided by x+5 less than or equal to 0
coldgirl [10]
It is more than 0, because you cancel the x, and you get 2+5, which is 7
