y = -10x + - 4

The given point: (0, -4)

To know if it is a solution, we need to replace the y and x with the points given.

If the result on the left hand side is the same as the right hand side then, it is a solution

x =0, y = -4

-4 = -10(0) + -4

-4 = 0 + (-4)

Multiplication of same sign gives positive number. Multiplication of opposite signs give negative number.

-4 = 0 - 4

-4 = -4

The left hand side is the same as the right hand side. Hence, it is a solution

Answer:

Yes it is a solution

Step-by-step explanation:

y = -10x + - 4

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.

f(0) = -3

f(1) = f(0) + 0.5 = -3 + 0.5 = -2.5

f(2) = f(1) + 0.5 = -2.5 + 0.5 = -2

f(3) = f(2) + 0.5 = -2 + 0.5 = -1.5

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

(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 .

Answer:

110

Step-by-step explanation:

To find the measure of the exterior angle we first need to find the value of t.

The sum of interior angles in a triangle is equal to 180° so we can write the following equation:

t + 10 + t + t + 20 = 180 add like terms

3t + 30 = 180 subtract 30 from both sides

3t = 150 divide both sides by 3

t = 50

The exterior angles and the angle represented with t + 20 make a straight line

and they are supplementary angles so their sum is equal to 180

t + 20 = 70 to complete this to 180 we need 110

The dimensions of the mold are a length and width of 3 inches and a height of 7 inches.

The volume of a rectangular prism is the space that it contains. We know that the volume of any prism is calculated by multiplying its base area by its height.

Given :

Let's assume that the length and the width of the "box" is x.

It is said that the height is 4 inches greater, so the height is x+4.

The volume of the mold is:

V = (x)(x)(x +4)

V = x²(x +4 ) using the Distributive Property.

V = x³ + 4x²

Since from the question we have Volume = 63 cubic inches

The equation we have is,

63 = x³ + 4x²

Subtracting 63 from both sides of the equation,

x³ + 4x²- 63 = 0

The cubic equation can be written as,

(x−3)(x²+7x+21) = 0

The solution of the quadratic equation (x²+7x+21) is,

x = -b ±√(b² - 4ac) / 2a

a = 1 , b =7 and c = 21

Substituting the values in the formula,

x = -7 ±√(7² - 4(1(21)) / 2(1)

x = -7 ±√-35 / 2

Hence,there are no real solutions to the quadratic equation.

There is only one real solution to the equation x = 3.

Therefore, the length and width of the rectangular prism are 3 inches and the height is x+4 = 3+4 = 7 inches.

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

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.

Since y is directly proportional to x then the value of y is 8

In a proportional relationship, one variable is always equal to the constant value of the other.

It is clear that y increases in proportion to x by applying the direct proportionality formula, y = kx.

Given y is directly proportional to x.

Therefore y = kx

now at x = 20 , y = 16/5

∴16/5 = 20 k

or, k = 16 /100

Now at x = 50 ,

Y = 16 /100 × 50

Answer: a = 2.2

$139,450

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

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
