The owner of a moving company typically has his most experienced manager predict the total number of labor hours that will be re

quired to complete an upcoming move. This approach has proved useful in the past, but the owner has the business objective of developing a more accurate method of predicting labor hours. In a preliminary effort to provide a more accurate method, the owner has decided to use the number of cubic feet moved and the number of pieces of large furniture as the independent variables and has collected data for 36 moves in which the origin and destination were within the borough of Manhattan in New York City and the travel time was an insignificant portion of the hours worked. If the sum of squares Y is 2,685.9 and the sum of squares error is 123.97.

Answer:

0.9538

Step-by-step explanation:

The computation of the proportion of variation in labor hours is explained by the number of cubic feet moved is shown below:

Here the R^2 coefficient of determination, would be determined and applied the same

R^2 = 1 - SSE ÷ SST

= 1 - 123.97 ÷ 2685.9

= 0.9538

Suzanne is looking at taking out a personal loan. Opportunity Loans is offering her $1600 at 3.45% for 1 year, with interest com
AleksAgata [21]

Step-by-step explanation:

So the general formula for compound interest is A = P(1+\frac{r}{n})^{nt} where r is the interest rate, t is the time in years, and n is the amount of compounds per year. So plugging in the values for both equations you'll get

Opportunity Loans:

 A = 1600(1+\frac{0.0345}{12})^{(12)(1)}

 A = 1600(1.002875)^{12}

 A \approx 1600(1.035)

 A = \$1,656.08

  Now to find the interest accrued on this loan you simply subtract 1600 from the A or final amount

 Interest=1656.08-1600\\Interest=56.08

General Loans:

 A = 1600(1+\frac{0.042}{4})^{(4)(1)}

 A = 1600(1.0105)^4

 A \approx 1600(1.042)

 A = 1,668.27

 To find the interest we do the same thing we did in the previous problem

 interest = 1668.27-1600\\interest=68.27

Opportunity loans has the least amount of interest after a year

Answer:

<em>Alma needs $35.28 to purchase the lace for her pillow.</em>

Step-by-step explanation:

If it is a square, the length and the width would be the same. You have to take the square root of the area, so the square root of 324 is 18. Now, we know that the length is 18 cm and the width is also 18 cm. If she's selling every 2 centimeters for 98 cents, you have to find the total amount of centimeters the pillow has, so 18*4 (the 4 comes from the number of sides on the pillow)=72.

Now divide that answer by the 2 lace centimeters she will get. (72/2=36 cm).

Now multiply that by 98 cents, the cost. (36*0.98=35.28).

So Alma needs $35.28 to purchase the lace for her pillow.
