In the year 2003, a person bought a new car for $25000. For each consecutive year
after that, the value of the car depreciated by 12%. How much would the car be worth
in the year 2006, to the nearest hundred dollars?

Answer:

48°

Step-by-step explanation:

All the angles in a triangle sum up to 180°.

Therefore,

x°+74°+58°=180°

→x°+132=180°

x°=180-132=48°

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

Answer:

20

Step-by-step explanation:

42 is the biggest and the smallest is 22 so 42-22 = 20!

Answer:

he pay 12.50 in 60 min

Step-by-step explanation:

he pay x in 390 min

x=(12.50 x 390)÷ 60

x=4875 ÷60

x=81.25 £

he pay finally £81.25

Step-by-step explanation:

Answer:

70°

Step-by-step explanation:

If arc BY is 40, angle BAY is 20.

BAC is 90.

90-20 is 70.

m<YAC=70

Answer:

16 in

Step-by-step explanation:

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: #7  x=16  #9 x=27

Step-by-step explanation:

#7

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

7x+19=11x-89

108=4x

27=x

Answer:

The answer is 43/10

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

Step-by-step explanation:

Answer:

Pvalue of 0.0446 < 0.05, which means that we reject the null hypothesis and accept the alternative hypothesis, that the true mean is larger than the specification.

Step-by-step explanation:

The average weight of a package of rolled oats is supposed to be at most 18 ounces.

This means that the null hypothesis is:

[tex]H_{0}: \mu \leq 18[/tex]

Is the true mean larger than the specification?

Due to the question asked, the alternate hypothesis is:

[tex]H_{a}: \mu > 18[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

18 is tested at the null hypothesis:

This means that [tex]\mu = 18[/tex]

A sample of 18 packages shows a mean of 18.20 ounces with a sample standard deviation of 0.50 ounces.

This means that [tex]n = 18, X = 18.2, \sigma = 0.5[/tex]

Value of the test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{18.2 - 18}{\frac{0.5}{\sqrt{18}}}[/tex]

[tex]z = 1.7[/tex]

Pvalue of the test:

Probability of finding a sample mean above 18.2, which is 1 subtracted by the pvalue of z = 1.7.

Looking at the z-table, z = 1.7 has a pvalue of 0.9554.

1 - 0.9554 = 0.0446

0.0446 < 0.05, which means that we reject the null hypothesis and accept the alternative hypothesis, that the true mean is larger than the specification.

Answer:

y-4=3/2(x+4)

Step-by-step explanation:

If you plug the numbers into the equation (y-y1=m(x-x1)), you get y-4=3/2(x+4).

Step-by-step explanation:

What is the radius of a circle whose diameter is 13 units? This means that the diameter is double the length of the radius. To find the radius, do: ∴, the radius is 13 2 units or 7.5 units.

Answer:

6.5dm

Step-by-step explanation:

Diameter is twice radius

radius =13÷2
