Use this data in the problem below. Follow the steps carefully. Lot 1:

Week 1: 600
Week 2: 300
Week 3: 500
Week 4: 900

Step 1. Jim enters the data and calculates the average or mean.
Step 2. Jim calculates the deviation from the mean by subtracting the mean from each value.
Step 3. Jim squares each deviation to remove negative signs.
Step 4. Jim sums the squares of each deviation and divides by the count for the variance.
Step 5. Jim takes the square root of the variance to find the standard deviation.

this is answer of 144 cubic meters

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

yes
