For the definition "An angle is 2 collinear rays with a common endpoint" , then

(a) the contradictory example is "When two rays are collinear having a  common end point; then the rays do not form an angle instead they form a line."

(b) the changed definition is , "An angle is formed at the intersection of two non-collinear rays that have the same endpoint " ;

(c) the example is "the Plane" .

The Angles are formed when the two straight lines or rays meet at a common endpoint.

Part(a) ;

An example which contradicts this definition of angles is "When two rays are collinear with a common endpoint; the rays do not form an angle ,instead  they form a line" because when all the points of two lines are collinear then all the points of the two lines will be overlapping .

Part(b) ;

The change that need to be made in the definition of angle is "An angle is formed at intersection of two non-collinear rays which have same endpoint ".

Part(c) ;

The Example of the undefined term is :

Undefined terms do not have a formal definition; an example of this is "the plane" . The plane pertains to the angles because the plane determines the parameter to be measured.

The given question is incomplete , the complete question is

An angle is two collinear rays with a common endpoint.

The experimental probability that a person selected at random is going to City C is 4/25.

Number of responses from destination A = 22

Number of responses from destination B = 40

Number of responses from destination C = 16

Number of responses from destination D = 14

Number of responses from destination E = 8

As we know, the formula of experimental probability is

Probability of an Event P(E) = Total Number of times an event occurs/Total number of trials.

Number of responses from destination C = 16

Total number of responses from all destinations = 100

∴ Probability of an Event P(C) = 16/100 = 4/25

Step-by-step explanation:

In order to determine if the circular tabletop with a diameter of 88 inches will fit through the door, we must compare the dimensions of the tabletop to the dimensions of the door.

The width of the door is 36 inches and the height of the door is 84 inches. The diameter of the tabletop is 88 inches. To fit through the door, the tabletop's diameter must be less than or equal to both the width and the height of the door.

88 inches > 36 inches and 88 inches > 84 inches

In this case, the tabletop will not fit through the door because its diameter is larger than both the width and the height of the door.

According to Isabella transactions, her present balance in bank statement is -$9.45

The term called transaction in math is defined as  a finalized agreement between a seller and a buyer for transferring goods, services, or financial assets in exchange for money

Here let us consider that Isabella's present balance be X.

According to the problem statements regarding her deposits, there is withdrawals, auto-payments, direct deposit and service charge are also done on the account.

Then those transaction values are calculated as,

=> (1/2)x - (1/3)x -(1/4)x +(1/10x) -$9.29 = x

Here by finding the LCM of common terms, then we get

=> (1/60)x - $9.29 = x

When we solve it for x, then we get the equation like the following,

=> 59x = -$9.29 × 60

=> 59x = -$557.4

Answer: y=-2x-19

Step-by-step explanation:

First, you should arrange the equation in the form of y=mx+c (that is the standard form of this type of equation)

10x+5y=15

       5y=-10x+15

       [tex]\frac{5y}{5} =\frac{-10x}{5}+\frac{15}{5}[/tex]

         y=-2x+3 (now you got the equation in the simple form)

now you should substitute the given point (-10,1) into the simplified equation

y= 1 & x=-10

1=-2(-10)+c  (the y-intercept must be taken as c )

c= 1 - 20

c= -19

therefore the equation will be : y=-2x-19

it will be the same gradient as the other line for this line too as the lines are parallel, you should only find the y-intercept. The gradient of the other line will stay the same as long as they are parallel lines.

The object has both kinetic energy and potential energy.

The values of each type of energy the object has are KE = 67.5 J

GPE = 367.5 J

Energy is the ability to do work. It can take many forms, such as kinetic energy (energy of motion), potential energy (stored energy) etc.

If a 15-kg child is tossed up into the air by her parent and the child is 2.5 meters off the ground traveling 3 m/s.

Then boy has kinetic energy due to his motion and also has potential energy due to his height.

Thus, M = 15-kg, h = 2.5 meters and V = 3 m/s

KE = 1/2(M)(V)² = 1/2 × 15 × 3² = 67.5 J

As per the formula of compound interest the amount in his account after 6 year 3 months is $40,085.307

In math the term called compound interest is defined as when you earn interest on both the money you've saved and the interest you earn.

Here we know that Luke invests 34000 into an account that pays 3. 4% compound interest per annum for the first two years and 2. 3% thereafter.

Here we need to find the amount in his account after 6 years and 3 months.

Then it can be calculated as,

FV = PV(1 + i)ⁿ

Here we know that PV = 34000 and i = 3.4% for two years,

Then the FV is value is calculated as,

=> FV = 34000(1 + 3.4/100)²

=> FV = 34000 ( 1 + 0.034)²

=> FV = 36351.304

Similarly, the FV value of 4 years 3 months is calculated as,

=>  FV = 36351.304(1 + 2.3/100)⁴°³

Let x be the cost price of an entertainment system.

The selling price is x+800

The number of systems sold is 60-((x+800-x)/20) = 60-((800)/20) = 60-40 = 20 systems

The revenue is the product of the number of systems sold and the selling price.

R = 20(x+800) = 20x+16000

To maximize the revenue, we need to differentiate the above equation with respect to x and set it to 0 and solve for x.

dR/dx = 20 = 0

20x = 0

x = 0

Therefore, the cost price of an entertainment system is 0 and the store should sell the system at x+800 = 800

This means that the store should sell the system at $800 more than the cost price to maximize the revenue.

Answer: 12

Step-by-step explanation:

Say that your friends number is x

She says that when you divide the number by 4, add 6, and then multiply by -3, the result is -27, so:

(x/4 + 6) * -3 = -27

We can solve the equation by first dividing by -3 on both sides:

x/4 + 6 = 9

Multiply both sides by 4:

x + 24 = 36

Subtract 24 from both sides:

x = 12

Double checking...

(12/4 + 6) * -3

= (3+6) * -3

= 9 * -3

= -27

Correct :>

So your friend chose the number 12

The solution to the equation is described as follows:

The equation says that a number was divided by 5 and that 3 was then subtracted from the quotient, giving the result 2. So, working backward, first add 3 to 2, giving 5. Then multiply that result by 5, giving x = 25.

The equation for this problem is described as follows:

x/5 - 3 = 2.

We must isolate the variable x, hence the first step is adding 3 to 2, as follows:

x/5 = 2 + 3

x/5 = 5.

Then we apply cross multiplication, multiplying the result by 5, as follows:

x = 5(5)

Answer:

The function rule for this set of ordered pairs is y = 2x + 1.

This can be determined by using the slope-intercept form of a linear equation, y = mx + b, where m is the slope and b is the y-intercept.

The slope (m) can be calculated by using the formula:

m = (change in y) / (change in x)

For the ordered pair (1, 3) and (3, 7), we can see that change in x = 3 - 1 = 2 and change in y = 7 - 3 = 4, so m = 4/2 = 2.

Then, using any of the point we can find the b which is y-intercept. let's take the point (-2, -3) and substitute the values in the function y = 2x + b

-3 = 2(-2) + b

-3 = -4 + b

b = 1

So, the function rule is y = 2x + 1

The scientific notation of the given result is 8 x 10³

The number b shows the order, which is the most important figure for which scientific notation is used. It tells us how much order large or small a value is in powers of 10. We can for a time, ignore the value of 'a' for two comparable quantities and only compare their orders(this type of comparison is useful when difference is too big, like size of human to size of a star etc sort of comparisons).

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can vary from 0 to 1, with 0 being an impossibility and 1 denoting a certainty. Probability is a crucial subject since it teaches all the fundamental ideas of the subject. One is the probability of every event in a sample space.

Answer

undefined

Step-by-step explanation:

Answer:

The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).

To find the equation of a line passing through two given points, we can use the slope-intercept form, and use the slope formula:

slope = (y2 - y1) / (x2 - x1)

Given the points (2, -4) and (2, -5), we can see that the x-coordinates are the same, which means that the line is a vertical line.

Since the line is vertical, the slope is undefined, and we can say the line can be represented by the equation x = 2

This is the equation of the line passing through the given points (2, -4) and (2, -5) in slope-intercept form.
