This table shows a proportional relationship. x −4 −2 0 2 4
y −14 −7 0 7 14
Which ordered pair could also belong to this relationship?
A. (−6, 21) C. (−1, −3)
B. (1, 3) D (6, 2)

Answers

Answer:

D (6, 21)

Step-by-step explanation:

Since the ratio of the corresponding values of x and y given in the table is 2 : 7

So, 6/ 21 = 2/7 = 2: 7

Thus, D (6, 21) is the correct answer.

Answer:

  sin(X) = (√119)/12

  cos(X) = 5/12

Step-by-step explanation:

The mnemonic SOH CAH TOA can help you remember the relevant ratios.

  Sin = Opposite/Hypotenuse

  sin(X) = YZ/YX

  sin(X) = (√119)/12

__

  Cos = Adjacent/Hypotenuse

  cos(X) = XZ/XY

  cos(X) = 5/12

O C.212) = 2(5)
O D.V2 = 5/2

Answers

Answer:

D. 21.

Step-by-step explanation:

The general form of the equation of a circle is:

(x - a)^2 + (y - b)^2 = r^2  where r is the radius.

Comparing:

(x + 5)^2 + (y + 7)^2 = 21^2

So r^2 = 21^2

making r = √21^2

= 21.

This is an isosceles triangle, so the angles formed at the base of the congruent sides are equal.

5x-7=8x-55

48=3x

16=x

#9

This is an equilateral triangle (if 2 angles are 60, the third has to be 60 as well) so the sides are equal

Consider the following time series data. Week 1 2 3 4 5 6 Value 18 12 15 10 18 14 Using the naive method (most recent value) as the forecast for the next week, compute the following measures of forecast accuracy. (a) mean absolute error MAE = (b) mean squared error MSE = (c) mean absolute percentage error (Round your answer to two decimal places.) MAPE = % (d) What is the forecast for week 7?

Answers

Answer:

(a) MAE = 5.20

(b) MSE = 10

(c) MAPE = 38.60%

(d) Forecast for week 7 = 14

Step-by-step explanation:

Note: See the attached excel for the calculations of the Error, Error^2, and Error %.

(a) mean absolute error

MAE = Total of absolute value of error / Number of observations considered = |Error| / 5 = 26 / 5 = 5.20

(b) mean squared error

MSE = Total of Error^2 / Number of observations considered = Error^2 / 5 = 150 / 5 = 10

(c) mean absolute percentage error (Round your answer to two decimal places.)

MAPE = Total of Error % / Number of observations considered = Error % / 5 = 193.02 / 5 = 38.60%

(d) What is the forecast for week 7?

Since the forecast is based on the naive method (most recent value), the forecast for week 7 is value for week 6. Therefore, we have:

Forecast for week 7 = 14
