Answer:

${ \tt{area = (7 \times 10) + (12 \times 4) + (5 \times 5)}} \\ { \tt{ = 70 + 48 + 25}} \\ { \tt{ = 143 \: {in}^{2} }}$

In a sample of n = 6 scores, the smallest score is X = 3, the largest score is X = 10, and the mean is M = 6. If the largest sco

Murrr4er [49]

Answer:

Step-by-step explanation:

Given that in a sample of n = 6 scores, the smallest score is X = 3, the largest score is X = 10

Mean = 6

Since mean = 6 we get sum of all the 6 scores = $6(6) = 36$

Now II part says 10 is changed to 20

i.e. original sum = 36

Changed value = 10

Adjusted value =26

Add: new value =22

New sum =48

So we have sum = 48

New mean= $\frac{48}{6} =8$

(This can also be done using the formula

old mean + positive change in one score/6)

(-1,4) and (3,16) in point slope form

Klio2033 [76]

Answer:

The equation of the line is y - 16 = 3(x - 3)

Step-by-step explanation:

To find the equation of this line, we first need to find the slope. To do that, we use the slope equation.

m(slope) = (y2 - y1)/(x2 - x1)

m = (16 - 4)/(3 - -1)

m = (16 - 4)/(3 + 1)

m = 12/4

m = 3

Now that we have the slope, we can use it and either point in point-slope form.

y - y1 = m(x - x1)

y - 16 = 3(x - 3)
