A.  The payback period is 7.2 years. The net present value of the proposed investment is 3720.55.

B. No, the project does not meet the company's cash payback criteria.

C.  Yes, the project does meet the net present value criteria for acceptance.

A. The truck costs $55,440 and generates annual cost savings of $7,700. So the payback period is the cost of the truck divided the expected amount the truck will generate.

                $55,440 / $7,700 = 7.2 years

To solve for the net present value, we say

Net Present Value = ∑ [(Cash inflow in period t) / (1 + [tex]r^{t}[/tex]] - Initial Investment.

NPV = (($7,700 / (1 + 0.08)¹) = 7 129.63

+ ($7,700 / (1 + 0.08)²) = 6601.51

+ .($7,700 / (1 + 0.08)³ = 6112.51

+ ($7,700 / (1 + 0.08)⁴) = 5659.73

+ ($7,700 / (1 + 0.08)⁵) = 5240.49

+ ($7,700 / (1 + 0.08)⁶) = 4 852.31

+ ($7,700 / (1 + 0.08)⁷) = 4492.88

+($7,700 / (1 + 0.08)⁸)  = 4160.07

+ ($27,600 / (1 + 0.08)⁸)) = 14911.42

- $55,440

We add all these values together and subtract by  $55,440

7 129.63 + 6601.51 + 6112.51 + 5659.73 + 5240.49 +4 852.31 + 4492.88 + 4160.07 + 14911.42 - $55,440

59160.55 - 55,440

NPV = 3720.55

B. The cash payback period of the project is 7.2 years. The company's cash payback criteria state that a project should not be accepted unless it has a payback period that is less than 50% of the asset's estimated useful life, which would be 4 years which is 50% of 8 years. Since 7.2 years is greater than 4 years, the project does not meet the company's cash payback criteria.

C. The positive NPV of $3,720.55 shows that embarking on the prooject will be valuable to the company. This means the project meets the NPV criteria for acceptance.

Answer:

  B.  (4, 8)

Step-by-step explanation:

You want the coordinates of R(1, 5) after translation by (1, -1) and dilation by a factor of 2.

Applying the given transformation, you have ...

  (x, y) ⇒ (x +1, y -1)

  R(1, 5) ⇒ R'(1 +1, 5 -1) = R'(2, 4)

The dilation multiplies each coordinate value by the dilation factor, 2.

  (x, y) ⇒ (2x, 2y)

  R'(2, 4) ⇒ R''(2·2, 2·4)  = R''(4, 8)

The coordinates after translation and dilation are (4, 8).

Hello!

the equation of the blue line is 3y + 0.5x

The probability that the student got an 'A' given they are male is approximately 0.12 or 12%.

To find the probability that a student got an 'A' given they are male, we need to use Bayes' theorem:

P(A | Male) = P(Male | A) × P(A) / P(Male)

We can find the values of the terms in the formula using the information given in the table:

P(Male) = (25/54) = 0.46 (the proportion of all students who are male)

P(A) = (17/54) = 0.31 (the proportion of all students who got an 'A')

P(Male | A) = (3/17) = 0.18 (the proportion of all students who are male and got an 'A')

Therefore, plugging these values into the formula:

P(A | Male) = 0.18 × 0.31 / 0.46

P(A | Male) ≈ 0.12

So the probability that the student got an 'A' given they are male is approximately 0.12 or 12%.

Volume = length X width X height =  8 x 2 x 6 = 96 m^3

The perimeters and areas of the rectangles are listed below:

Case 1: p = 54 yd, A = 170 yd²

Case 2: p = 46 m, A = 120 m²

Case 3: p = 44 mm, A = 72 mm²

Case 4: p = 60 in, A = 209 in²

Cases 5 / 6: p = 32 mi, A = 55 mi

Case 7: p = 66 m, A = 242 m²

Case 8: p = 94 yd, A = 550 yd²

Case 9: p = 72 km, A = 320 km²

In this problem we must determine the perimeter and the area of eight rectangles, whose formulae are introduced below:

Perimeter

p = 2 · (w + h)

Area

A = w · h

Where:

Now we determine the perimeter and the area for each case:

Case 1

p = 2 · (17 yd + 10 yd)

p = 54 yd

A = (17 yd) · (10 yd)

A = 170 yd²

Case 2

p = 2 · (15 m + 8 m)

p = 46 m

A = (15 m) · (8 m)

A = 120 m²

Case 3

p = 2 · (18 mm + 4 mm)

p = 44 mm

A = (18 mm) · (4 mm)

A = 72 mm²

Case 4

p = 2 · (11 in + 19 in)

p = 60 in

A = (11 in) · (19 in)

A = 209 in²

Cases 5 and 6

p = 2 · (5 mi + 11 mi)

p = 32 mi

A = (5 mi) · (11 mi)

A = 55 mi

Case 7

p = 2 · (22 m + 11 m)

p = 66 m

A = (22 m) · (11 m)

A = 242 m²

Case 8

p = 2 · (22 yd + 25 yd)

p = 94 yd

A = (22 yd) · (25 yd)

A = 550 yd²

Case 9

p = 2 · (16 km + 20 km)

The probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001

In a series of 36 trials, if the subject is guessing randomly, then the probability of correctly guessing odd or even is 1/2.

Let X be the number of correct guesses in a series of 36 trials. X follows a binomial distribution with parameters n = 36 and p = 1/2.

The probability of guessing more than 20 correct is:

P(X > 20) = 1 - P(X ≤ 20)

Using a binomial distribution table, we can find that P(X ≤ 20) = 0.9999 (rounded to four decimal places).

Therefore: P(X > 20) = 1 - 0.9999 = 0.0001

So the probability that a subject would guess more than 20 correct in a series of 36 trials is 0.0001 (rounded to four decimal places).

Bernie drove 1.125 times as fast as Janelle.

To determine who drove faster, we can calculate the average speed (in km/h) of each driver using the formula:

average speed = distance / time

For Janelle:

average speed = 60 km / (5/6 hours) = (60 km) x (6/5 hours) = 72 km/h

For Bernie:

average speed = 54 km / (2/3 hours) = (54 km) x (3/2 hours) = 81 km/h

1296 unit square will be the total surface area of the given figure.

To find the surface area of the given figure. first, we need to separate this graph into two cuboids such that,

The surface area of a cuboid is given by the formula:

A = 2lw + 2hw + 2lh

thus, for the upper cuboid,

A = 2*9*6+2*6*6+2*9*6

A=288

thus, for the lower cuboid,

A = 2*27*6+2*27*12+2*12*6

A=1116

So the total surface area = sum of the surface area of both cuboids - 2* area of the touching side

Total surface area = 1116+288-2*9*6

Therefore total surface area will be 1296.

The range of the given function y = |x| is [0, ∞).

As per the question, consider that the absolute value of any real number x is always non-negative.

Therefore, the output of the function y = |x| is always non-negative as well.

Furthermore, for any non-negative real number y, there are two possible inputs x that will produce that value of y: x and -x. For example, if y = 2, then x could be either 2 or -2.

Thus, every non-negative real number is in the range of y = |x|, and no negative numbers are in the range.

Inequalities can be represented on a number line such as that shown in the image attached below. The solid line shows the range of values that x can take. We put an open circle at −1 to show that although the solid line goes from −1, x cannot actually equal −1.

Inequalities are mathematical expressions involving the symbols >, <, ≥ and ≤.

To ‘solve’ an inequality means to find a range, or ranges, of values that an unknown x can take and still satisfy the inequality.

Suppose we want to solve the inequality x + 3 > 2.

We can solve this by subtracting 3 from both sides:

x + 3 > 2

x > −1

So the solution is x > −1.

We can say that a chip can hold 1 billion transistors in the year 2007.

To solve for the year when a chip can hold 1 billion transistors, we need to set the function f(x) equal to 1000 (since 1 billion is 1000 million).

So,[tex]42(1.41)^x = 1000[/tex]

Divide both sides by 42:

[tex](1.41)^x = 23.81[/tex]

Take the logarithm of both sides (with base 1.41):

x = log(23.81)

Using a calculator, we find that x is approximately 5.98.

Since X represents the number of years since 2000, we add 5.98 to 2000 to get the year when a chip can hold 1 billion transistors:

2000 + 5.98 = 2006.98

Rounding to the nearest year, we can say that a chip can hold 1 billion transistors in the year 2007.

A regression through the origin is a linear regression model where the intercept time period is assumed to be 0, meaning the regression line passes through the starting place.

This version is also referred to as zero-intercept regression or homogeneous regression.

It's far frequently used whilst there's a theoretical foundation to agree with that the relationship among the dependent and unbiased variable passes via the foundation or whilst the information propose that the intercept ought to be 0.

The slope coefficient represents the change within the structured variable for a one-unit increase inside the unbiased variable.
