The lottery's anticipated worth is $80.

Given that,

The probability of receiving $125 is 0.25; the likelihood of receiving $100 is 0.3; and the likelihood of receiving $50 is 0.45.

A) EV=125*.2+100*.3+50*.5=$80

The lottery's anticipated worth is $80.

The expected value is obtained by multiplying each result by its likelihood.

The expected value of the lottery is then calculated by adding up all of these.

This is what we have: ;;

125(0.2) + 100(0.3) + 50(0.5) (0.5)

= 25 + 30 + 25 = $80

B) This is the formula for variance is shown in figure :

So, we can calculate the variance as follows:

.2*(125-80)^2+.3*(100-80)^2+.5*(50-80)^2=975

C) A risk-neutral person would pay $80 or less to play the lottery.

Answer:

Step-by-step explanation:

Expected value of the lottery is $83.75.

Variance of the outcome is 909.6.

A risk-neutral person would pay $83.75 or less to play the lottery.

a) The expected value is obtained by multiplying each result by its likelihood.

The expected value of the lottery is then calculated by adding up all of these.

This is,

125(0.25) + 100(0.3) + 50(0.45)

          = $83.75

b) we can calculate the variance as follows:

Variance=.25*(125-83.75)^2+.3*(100-83.75)^2+.45*(50-80)^2=909.6

c) A risk-neutral person would pay $83.75 or less to play the lottery.

Both Laquita and Tori wrote a correct equation which is the correct answer would be an option (A).

Let the required line would be as

⇒ y - y₁ = [(y₂ - y₁)/(x₂ -x₁ )](x - x₁ )

Here x₁ = 0 and y₁ = 37

x₂ = 4 and y₂ = 99

The equation of the line is obtained by substituting these values into the above equation;

⇒ y - 37 = (62/4)x

⇒ y - 37 = 15.5x

⇒ y = 15.5x +37

This equation is written by Laquita.

Multiply by 2 both sides of the equation,

⇒ 2y = 31x + 74

⇒ 31x - 2y = 74

This equation is written by Tori.

Therefore, both Laquita and Tori wrote a correct equation.

(c) The car will take 0.4 hours to travel 26 miles at his speed .

In the question ,

it is given that

the car is traveling down a highway at a constant speed

and the equation representing is d =65*t

Part(a)

On comparing , the given equation with the equation of speed , time and distance

which is , distance = speed × time

on comparing both the equations , we get speed = 65 mph .

hence , 65 means the car will travel 65 miles in 1 hour .

Part(b)

substituting the value t = 1.5 hours in the given equation , we get

d = 65×1.5

= 97.5

hence , The car will travel 97.5 miles in 1.5 hours

Part(c)

Substituting the value of d = 26 miles in the given equation , we get

26 = 65×t

t = 26/65

t = 0.4 hours

hence , It takes the car 0.4 hours to travel 26 miles.

Therefore , (a) 65 means the car will travel 65 miles in 1 hour .

(b) The car will travel 97.5 miles in 1.5 hours .

==========================================================

Explanation:

asset = an item that is either cash or can be turned into cash

liability = something that needs to be paid back (eg: truck loan)

A = total assets

A = (homeValue) + (workEquipment) + (carValue) + (investments)

A = ( $175,742 ) + ($3,365) + ($44,346) + ($61,225)

A = $284,678

B = total liabilities

B = (mortgage)+(credit card balance)+(truck loan)

B = ($76,765)+($2,055)+($66,408)

B = $145,228

C = net worth

C = A - B

C = ($284,678) - ($145,228)

C = $139,450 which points us to choice A as the final answer.

The net worth of the carpenter is $144,633.

Given that, Home value = $175,742, Mortgage = $76,765, Credit card balance = $2,055, Owned work equipment = $3,365 and Car value = $44,346.

Net worth is the value of all the non-financial and financial assets owned by an individual or institution minus the value of all its outstanding liabilities.

Here,

Net worth = Financial assets - Liabilities

= (175,742+3,365+44,346) - (76,765+2,055)

= 223,453 - 78,820

= $144,633

Therefore, the net worth of the carpenter is $144,633.

The total surface area of the triangular prism is 756 meter²

Given,

A triangular prism and its net.

We have to find the surface area of the triangular prism.

First we can consider the right angled triangle.

Height = 9 meter

Base = 12 meter

Hypotenuse = 15 meter

Area of the right angled triangle = (1/2 bh)

Here,

Area = 2 × (1/2 bh) = 2 × (1/2 × 12 × 9) = 2 × 6 × 9 = 108 meter²

Now, area of right rectangle.

Area of rectangle = length × breadth

Here, the breadth of the rectangle is the height of the triangle = 9 meter

Length = 18 meter

Area = length × breadth = 9 × 18 = 162 meter²

Then, area of middle rectangle.

Length = 18 meter

Breadth = 12 meter

Area = length × breadth = 18 × 12 = 216 meter²

Next, area of left rectangle.

Length = 18 meter

Breadth = Hypotenuse of the triangle = 15 meter

Area = length × breadth = 18 × 15 = 270 meter²

Now, lets calculate the total surface area of the triangular prism.

Surface Area of triangular prism = 108 + 162 + 216 + 270 = 756 meter²

The most appropriate choice for velocity and accleration will be given by-  Deacceleration of a car of 15 [tex]m/s^2[/tex] is a real world situation for which the rate of change is -15

What is velocity and acceleration?

Velocity

The distance travelled by a body per unit interval of time where the direction of the motion of a body is taken into account is known as velocity.

Velocity is a vector quantity as direction of motion of body is taken into account.

If d is the displacement of body and t is the time,

Velocity = [tex]\frac{d}{t}[/tex]

Acceleration

The rate of change of velocity of a body is called acceleration.

Acceleration is a vector quantity as direction of motion of a body is taken into account.

If [tex]\Delta[/tex]v is the change of velocity and t is the time,

Acceleration = [tex]\frac{\Delta v}{t}[/tex]

If velocity decreases then it is called Deacceleration

Here

Deacceleration of a car is 15 [tex]m/s^2[/tex]

That means rate of change of velocity of a car is -15 [tex]m/s^2[/tex]

The probability that the randomly selected sample is vulnerable or critically endangered is equal to 0.76

The probability can be determined using the following formula;

probability = number of desired events or outcomes ÷ total number of events or outcomes

The total is known to be 45, the favorable or desired outcomes can be calculated as follows;

number of desired outcomes = number of vulnerable species + number of critically endangered species

number of desired outcomes = 12 + 22

number of desired outcomes = 34

Now we calculate the probability by using the above formula;

probability = 34 ÷ 45

probability = 0.76

Therefore, 0.76 is the probability that the randomly selected species is vulnerable or critically endangered.

Step-by-step explanation:

The function g(x) is a dilated form of f(x) and the dilation scale factor [K] in this case is (3/4). The graphs f(x) and g(x) are attached with the answer.

The general equation of a straight line is -

y = mx + c

Where -

[m] is the slope of the line.

[c] is the y - intercept.

Given is the following equation-

g(x) = 3/4 f(x)

Since, the functions are not given, we will assume them by ourselves. You can use the same procedure for any pair of functions of the form -g(x) = n f(x)

Assume that -

f(x) = 2x + 1

Now -

g(x) = (3/4) f(x)

g(x) = (3/4)(2x + 1)

g(x) = (3/2)x + 3/4

Now, both the graphs f(x) and g(x) are attached below. In general, g(x) is a dilated form of f(x) and the dilation scale factor [K] in this case is (3/4).

Let p(x) be the required polynomial.

we are given that p(x) has a zero 1 with multiplicity 2

in other word, this means that (x-1) occurs twice as a factor of p(x).

Expressions with polynomial functions include variables with various degrees, non-zero coefficients, positive exponents (of variables), and constants. A polynomial in "b" of degree 2 is, for instance, f(b) = 4b2 - 6.

Likewise, (x-3) appears as a factor of p(x) once.

we are also given that the degree of p(x) is 3.

So, p(x) can not have more than 3 linear factors.

Altogether,

p(x) = k(x-1)^2  (x-3), where constant k ∈ R - {0}.

We may take k = 1 and get the desired polynomial,

p(x) = ( x-1)^2 ( x-3) = x^3 - 5x^2 +7x -3
