What is the equation of the graphed linear model?<br><br> y = ? x + ?
miss Akunina [59]
Use slope intercept form for equation, which is y = mx +b. m is slope and b is the y-intercept.

Find slope by change in y over change in x. So pick two points, for example (0, 24) and (2, 20). Slope (m) will be
(y2-y1)/(x2-x1)
= (24-20)/(0-2)
= 4/-2
m = -2

Y-intercept is 24.

Equation is y = -2x + 24

Find the amount of sap the maple syrup producer collected from each tree if the total amount (5 gallons) was redistributed equal
Afina-wow [57]
The picture in the attached figure

we know that
total amount of sap =[3*(1/4)+2*(3/8)+4*(5/8)+1*(1)]
total amount of sap =[(3/4)+(6/8)+(20/8)+(1)]
total amount of sap =[(3/4)+(3/4)+(10/4)+(4/4)]
total amount of sap =[20/4]
total amount of sap =5 gallons
total of trees=10

<span>[amount of sap collected from each tree]=total amount of sap/total of trees
</span>
[amount of sap collected from each tree]=5/10----> 0.5 gallons per tree

the answer is
0.5 gallons

A set of three scores consists of the values 3, 7, and 2.<br> Σ2X – 2 = <br> Σ(X – 1)² =
AfilCa [17]

Answer:

Step-by-step explanation:

Given the set of datas 3, 7 and 2, we are to evaluate the folowing;

Σ2X – 2 and Σ(X – 1)² =where X are the individual datas.

We will substitute each of the data as value of X and ten take the sum as shown;

For Σ2X – 2

Σ2X – 2 = [2(3)-2]+[2(7)-2]+[2(2)-2]

Σ2X – 2 = (6-2)+(14-2)+(4-2)

Σ2X – 2 = 4+12+2

Σ2X – 2 = 18

For Σ(X – 1)² where x values are also 3, 7 and 2 we will have;

Σ(X – 1)² = (3 – 1)²+(7 – 1)²+(2 – 1)²

Σ(X – 1)² = 2²+6²+1²

Σ(X – 1)² = 4+36+1

Σ(X – 1)² = 41
