fgiga [73]
Part A:

Given that a<span> bag contains 10 white golf balls and 6 striped golf balls, the ratio of white to striped golf balls is 10 : 6 = 5 : 3.

Given that </span>a<span> golfer wants to add 122 golf balls to the bag, the of balls each he should add is given by:

5\left( \frac{122}{5+3} \right) \ : \ 3\left( \frac{122}{5+3} \right)=5\left( \frac{122}{8} \right) \ : \ 3\left( \frac{122}{8} \right) \\  \\ =5(15.25) \ : \ 3(15.25)=76.25 \ : \ 45.75 \\  \\ \approx76:46

Therefore, the golfer shold add 76 white golf balls and 46 striped golf balls.



Part B.

You did not indicate the scale factor.

Assuming the scale factor is given by D(o, k) where k can be any number, then the cordinate of the </span><span>coordinates of the image of the quadrilateral VWXY are given by:

V'(6k, 2k), W(-2k, 4k), X(-3k, -2k), Y(3k,-5k)

That is you multiply the scale factor to the coordinates of the preimage to get the coordinates of the image.

Marta_Voda [28]

Answer and explanation:

Given : The demand for a product for the last six years has been 15, 15, 17, 18, 20, and 19. The manager wants to predict the demand for this time series using the following simple linear trend equation : tr_t = 12 + 2t

To find : What are the forecast errors for the 5th and 6th years?

Solution :

Data : 15, 15, 17, 18, 20, and 19.

The simple linear trend equation is given as, tr_t = 12 + 2t

For t = 5 years

tr_t = 12 + 2(5)

tr_t = 12 +10

tr_t = 22

Observed tr_t = 20

Predicted tr_t = 22

Forecast error = Observed – Predicted = 20 – 22 = -2

Absolute forecast error = |-2| = 2 .

For t = 6 years

tr_t = 12 + 2(6)

tr_t = 12 +12

tr_t = 24

Observed tr_t = 19

Predicted tr_t = 24

Forecast error = Observed – Predicted = 19 – 24 = -5

Absolute forecast error = |-5| = 5.

LiRa [457]

Answer:

Mean: 3.5263157894737

Median: 3

Mode: 3

Step-by-step explanation: The mode is 3 because the mode is for which number pops up the most, which is 3.

I got the median by crossing out 8 from the left and the right of the number set and got 3 as the last number.

I got the mean by adding up all the numbers and divided it by the amount of numbers in the set.
