What is probability index?

The present value of benefits for each dollar of investment is calculated using the profitability index approach. In other words, it involves the ratio that is produced by comparing the ratio of the initial investment to the present value of future cash flows from a project.

A solid investment is one with a profitability index of greater than 1.0, with higher values indicating more alluring enterprises.

The ratio between the initial investment and the present value of future cash flows is measured by the profitability index (PI). The index can be used to rate investment projects and display the value produced per investment dollar.

Profitability Index = Present Value of Cash INflows / Present Value of Cash Outflows

Project : Profitability Index

A : 1.8434 (765,000 / 415,000)

B : 1.8043 (415,000 / 230,000)

The Coordinates of the centroid of a triangle with the given vertices are (0, 4), (8, 10) and (6, 1) is (14/3, 5) and Centroid of triangle with vertices (1,5),(3,8),(0,2) is (4/3, 5).

The centroid of a triangle is one of the point where all three medians of the triangle intersect. The median is a line segment drawn from one vertex to the midpoint on the opposite side. Triangle centroid divides each median into individual words in a 2:1 ratio. The centroid is usually at 2/3 of the median.

If the three vertices of a triangle are A(x₁,y₁) B(x₂,y₂), C(x₃,y₃), the centroid of the triangle is given by the formula :

G(x₁+x₂+x₃/3, y₁+y₂+y₃/3 ).

We have , two triangles with vertices,

a) triangle whose vertices are A(0, 4), B(8, 10) and C(6, 0). So, the coordinates of the centroid of a triangle whose vertices are (0, 4), (8, 10) and (6 , 1) are ( (0+8+6)/3 , (4+10+1)/3 ) or (14/3, 5).

b) triangle whose vertices are P(1, 5), Q(3,8) and R(0, 2). So, the coordinates of the centroid of a ∆PQR are ( (1+3+0)/3 , (5+8+2)/3 ) or (4/3, 5).

The linear function is y = 5x + 12 and the number of customers after 3 and 4 hours are 27 and 41 respectively.

A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. Isn't it looking like the slope-intercept form of a line which is expressed as y = mx + b? Yes, this is because a linear function represents a line, i.e., its graph is a line.

Using the data in the table, we can write can a linear function to represent it.

Taking two points;

The slope of the line is calculated as;

m = y₂ - y₁ / x₂ - x₁

m = 17 - 12 / 1 - 0

m = 5 / 1

m = 5

Using the value of the slope to calculate the y - intercept.

y = mx + b

17 = 5(1) + b

17 = 5 + b

b = 17 - 5

b = 12

The linear function is written as y = 5x + 12

a) The number of customers in the store after 3 hours is

y = 5x + 12

y = 5(3) + 12

y = 15 + 12

y = 27

Answer:

To solve the equation |2x - 5| = 7, you can set up two equations, one for the positive solution and one for the negative solution.

For the positive solution, you can start by isolating the absolute value expression on the left-hand side of the equation: |2x - 5| = 7 can be rewritten as 2x - 5 = 7. Then, you can solve this equation by adding 5 to both sides to get 2x = 12, and then dividing both sides by 2 to get x = 6.

For the negative solution, you can start by noting that the absolute value of a number is equal to its opposite if it is negative, so |2x - 5| = 7 can be rewritten as -(2x - 5) = 7. This equation can be solved by multiplying both sides by -1 to get 2x - 5 = -7, and then adding 5 to both sides to get 2x = -2. Then, dividing both sides by 2 to get x = -1.

Therefore, the two equations to solve the equation |2x - 5| = 7 are 2x - 5 = 7 and 2x - 5 = -7.

Answer:

C

Step-by-step explanation:

To solve the equation |2x - 5| = 7, we need to set up two equations, one for the case where the absolute value is equal to the positive value of the expression inside the absolute value bars, and one for the case where the absolute value is equal to the negative value of the expression inside the absolute value bars.

The first equation we need to set up is 2x - 5 = 7. In this case, the absolute value is equal to the positive value of 2x - 5, so we can simply set the expression inside the absolute value bars equal to the given value of 7. This equation can be written as follows:

2x - 5 = 7

The second equation we need to set up is -(2x - 5) = 7. In this case, the absolute value is equal to the negative value of 2x - 5, so we need to set the negative of the expression inside the absolute value bars equal to the given value of 7. This equation can be written as follows:

-2x+5 = 7

We can use these two equations to solve for the value of x. To solve the first equation, we can simply add 5 to both sides to get 2x = 12, and then divide both sides by 2 to get x = 6. To solve the second equation, we can first distribute the negative sign to get -2x + 5 = 7, and then add 5 to both sides to get -2x = 2. Finally, we can divide both sides by -2 to get x = -1.

Therefore, the two solutions to the equation |2x - 5| = 7 are x = 6 and x = -1.

Alternative:

2x-5 = 7

2x-5 = -7

The given series is convergent and the first term is 4 and the common ratio is -0.5 and the sum of the series is 8/3 .

The given series is 4 - 4/2+ 4/4 - 4/8 +...

We can see that the first term of the geometric series is 4

Hence a = 4

The second term is  -4/2 and the third term is 4/4

Hence r = 4 ÷ (-4/2) = -4/2 ÷ 4/4 = - 1/2 or -0.5

Since the common ratio is less than 1 we can say that the series is convergent.

Now for a convergent series we know that the sum of the terms of the series is equal to

S = a / (1-r)

or, S = 4 / (1-(-0.5))

or, S = 4 / 1.5

or, S = 8/3

Hence the sum of the convergent series is 8/3 .

Both the ratio test and the root test are based on a comparison with a geometric series and hence function in comparable scenarios.

In fact, if the ratio test works (that is, if the limit exists and is not equal to 1), then so does the root test; the contrary is not true. The root test is thus more broad, although in practise, determining the limit for regularly encountered kinds of series is frequently challenging.

The Rational Root Theorem states that if a polynomial equation with integer coefficients has a rational root, then that root must be of the form p/q, where p is a factor of the constant term (in this case, 11) and q is a factor of the leading coefficient (in this case, 5).

You have to make sure x^2-16 ≥ 0 for the inner square root to stay in the real numbers.

You also have to make sure sqrt(x^2-16)-3 ≥ 0 for the outer square root to stay in the real numbers.

Solving x^2-16 ≥ 0 we have that x^2 ≥ 16, so either x≥4 or x≤-4.

The function f such that F = ∇f does not exist, and the answer is DNE (does not exist).

Generally, To determine whether or not the vector field is conservative, we need to check if its curl is zero. The curl of the given vector field is:

curl(F) = ∇ x F

          = (∂Fz/∂y - ∂Fy/∂z)i + (∂Fx/∂z - ∂Fz/∂x)j + (∂Fy/∂x - ∂Fx/∂y)k

Substituting in the values of the components of F, we get:

curl(F) = (-cos(z))i + (0)j + (-y sin(z))k

Since the curl of the vector field is nonzero, the vector field is not conservative.

Therefore, the solution is DNE, and the function f such that F = f does not exist (does not exist).
