The total operating cost to run the organic strawberry farm varies directly with its number of acres. What is the constant of va

kow [346]

Answer:

$16\ acres$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the number of acres

y ---> total operating costs

we have the ordered pair (20,551,520)

For x=20 acres, y=$551,520

<em>Find the value of the constant of proportionality k</em>

$k=\frac{y}{x}$

substitute the values of x and y

$k=\frac{551,520}{20}=\$27,576\ per\ acre$

The linear equation is equal to

$y=27,576x$

Find out how many acres are on a farm with a total operating cost of $441,216

For y=$441,216

substitute in the linear equation the value of y and solve for x

$441,216=27,576x$

$x=441,216/27,576$

$x=16\ acres$

The following information was collected from a simple random sample of a population. 16 19 18 17 20 18. The point estimate of th

Kruka [31]

Answer:( c ) 1.414

Step-by-step explanation:

Let m be mean

M=mean=sum/n

M= (16+19+18+17+20+18) / 6

M=108/6

M=18

Let start finding:

The standard deviation formula is= sqrt( Summation of |x-m|^2 / n-1)

|x-m|^2

For 1st: |16-18|^2=4

For 2nd: |19-18|^2=1

For 3rd: |18-18|^2=0

For 4th: |17-18|^2=1

For 5th: |20-18|^2=4

For 6th: |18-18|^2=0

Summation of |x-m|^2 =10

The standard deviation formula is :

S.D = sqrt( Summation of |x-m|^2 / n-1)

S.D= sqrt(10 / 5)

S.D=sqrt(2)

S.D= 1.414
