what is the measure of VKW?

Answer:

The formula is;

V = 275,000(0.9)^n

The value of the machine after 5 years is $162,384.75

Step-by-step explanation:

Here, we want to find the formula for the value of the machine after n years

Mathematically, we can use an exponential model for this

V = I ( 1 - r)^n

Where v is the value after n years

I is the value at which the machine was bought

r is the depreciation percentage ; 10% = 10/100 = 0.1

n is the number of years

Thus;

V = 275,000(1 - 0.1)^n

V = 275,000(0.9)^n

The value of the machine after 5 years will be;

V = 275,000(0.9)^5

V = 162,384.75

Answer:

C. [tex] y = -x + 2 [/tex]

Step-by-step explanation:

First, find the slope, m, of the line that passes through the two given points.

Slope = [tex] \frac{rise}{run} = \frac{-2}{2} = -\frac{1}{1} = -1 [/tex]

Next, determine the y-intercept, b.

The y-intercept is where the line intercepts the y-axis. The line intercepts the y-axis at y = 2. Therefore, b = 2.

Now, to get an equation of the line, substitute m = -1, and b = 2 in [tex] y = mx + b [/tex].

✅The equation would be:

[tex] y = -1x + 2 [/tex]

[tex] y = -x + 2 [/tex]

Answer:

102

Explanation: 66+36 (9 times 4 is 36 and u add it to the 66 because u have to add 9 four times.)

self check

66+9= 75 (1st slot)

75+9=84 (2nd slot)

84+9= 93 (3rd slot)

93+9= 102 (4th and final slot, what u were looking for to begin with)

Answer:

Step-by-step explanation:

It might help to use decimals

1 1/8 = 1.125

4 2/5 = 4.4

Add these together

1.125 + 4.4 = 5.525 That's the correct answer, but likely not in the form you wanted.

1 1/8 = 9/8

4 2/5 = 22/5

9/8 + 22/5

multiply through by the Lowest Common Denominator

9*5/40 + 22*8/40 =

45/40 + 176/40

221/40

5.525

5 21/40

You get the fraction by multiplying 40 * 0.525 which is 21

So you can express 0.525 as 21 / 40

Answer:

a)  The 90% confidence interval for the mean noise level at such locations      

  (112.46 , 163.54)

b) The critical value that should be used in constructing the confidence interval

Z₀.₁₀ = 1.645

Step-by-step explanation:

Step(i) :-

Noise levels at 3 airports were measured in decibels yielding the following data

108   146   160

Mean of given data

         [tex]x^{-} = \frac{108+146+160}{3} = 138[/tex]

x          :     108   146   160

x-x⁻      :      -30   8       22

(x-x⁻ )² :     900   64     484

Variance  σ ² = ∑(x-x⁻ )²/ n-1

                                        = [tex]\frac{900+64+484}{3-1}= 724[/tex]

Standard deviation  

                σ = √724 = 26.90

Step(ii):-

The 90% confidence interval for the mean noise level at such locations                        

       [tex](x^{-} - Z_{0.90} \frac{S.D}{\sqrt{n} } , (x^{-} + Z_{0.90} \frac{S.D}{\sqrt{n} } )[/tex]

The critical value that should be used in constructing the confidence interval

Z₀.₁₀ = 1.645

         [tex](138 - 1.645 \frac{26.90}{\sqrt{3} } , (138 + 1.645 \frac{26.90}{\sqrt{3} } )[/tex]

        ( 138 - 25.54 , 138 + 25.54 )

        (112.46 , 163.54)

Answer:

The value of E [Z]  is 0.50.

Step-by-step explanation:

The expected value is computed using the formula:

[tex]E(X)=\sum x\cdot P(X= x)[/tex]

Denote the three dices as follows:

X₁ = a four-sided die

X₂ = a six-sided die

X₃ = a 12-sided die

Define the indicator variables as follows:

[tex]I_{1}=\left \{ {{1;\ X_{1}=4} \atop {0;\ X_{1}\neq 4}} \right. \\\\I_{2}=\left \{ {{1;\ X_{2}=4} \atop {0;\ X_{2}\neq 4}} \right. \\\\I_{3}=\left \{ {{1;\ X_{3}=4} \atop {0;\ X_{3}\neq 4}} \right.[/tex]

The probability of rolling a 4 in the three dices are as follows:

[tex]P(X_{1}=4)=\frac{1}{4}\\\\P(X_{2}=4)=\frac{1}{6}\\\\P(X_{3}=4)=\frac{1}{12}[/tex]

Compute the value of E [Z] as follows:

[tex]E(Z)=E(I_{1})+E(I_{2})+E(I_{3})[/tex]

         [tex]=(1\times\frac{1}{4})+(1\times\frac{1}{6})+(1\times\frac{1}{12})\\\\=\frac{3+2+1}{12}\\\\=\frac{6}{12}\\\\=\frac{1}{2}\\\\=0.50[/tex]

Thus, the value of E [Z]  is 0.50.

Answer:

q = -2

Step-by-step explanation:

Constant = whole number

If the two lines are parallel the slopes would be equal.

So if the first line is y = -2x + 5/3

The the second line would become y = -2x + 6.

If q becomes -2, it will be a constant and the two lines will also be parallel

Answer:

(a) The proportion of international students in the statistic department is 25%.

(b) The proportion of master students among all domestic students is 20%.

Step-by-step explanation:

The following can first be obtained from the question:

Total number of graduate students = 60

Number of PhD students = 45

Number of Master students = 15

Percentage of international students among the master students = 40%

Percentage of international students among the PhD students = 20%

Number of international master students = Number of Master students * Percentage of international students among the master students = 15 * 40% = 6

Number of international PhD students = Number of PhD students * Percentage of international students among the PhD students = 45 * 20% = 9

The questions can now be answered as follows:

(a) What is the proportion of international students in the statistic department?

This can be calculated as follows:

Total number of international students = Number of international master students + Number of international PhD students = 6 + 9 = 15

Total number of graduate students = 60

Proportion of international students in the statistic department = Total number of international students / Total number of graduate students = 15 / 60 = 0.25, or 25%

Therefore, the proportion of international students in the statistic department is 25%.

(b) What is the proportion of master students among all domestic students.

This can be calculated as follows:

Total number of graduate students = 60

Total number of international students = Number of international master students + Number of international PhD students = 6 + 9 = 15

Total number of domestic students = Total number of graduate students - Total number of international students = 60 - 15 = 45

Number of Master students = 15

Number of international master students = Number of Master students * Percentage of international students among the master students = 15 * 40% = 6

Number of domestic master students = Number of Master students - Number of international master students = 15 - 6 = 9

Proportion of master students among all domestic students = Number of domestic master students / Total number of domestic students = 9 / 45 = 0.20, or 20%

Therefore, the proportion of master students among all domestic students is 20%.
