The average payment will be $611.64.

It should be noted that average means mean. This implies that we will add the numbers and then divide.

This will be:

= ($23.42 + $14.95 + $276.50 + $219.93 + $76.84) / 5.

= $611.64

Therefore, the average payment will be $611.64.

The value of K is 2 so that the point A lies on the line given by the equation A (2,1), 3x+ky=8.

Given: Equation is 3x+ky=8

Points A (2,1)

We need to determine the value for K

3x+ky=8   — 1 (Take as equation 1)

Substitute the points in equation 1

So, we take x = 2 and y = 1

3(2) +k (1) = 8

6+k = 8

k = 8 - 6

k = 2

When graphing points on a coordinate plane, it is often helpful to find the value of k that makes the point lie on a line. For this problem, k = 2 so that A (2,1), 3x+ky=8.

The area of the isosceles triangle is 60 square units

The formula for area of an isosceles triangle is expressed as;

Area = bh/2

Where;

Now, let's find the height of the triangle.

Using Pythagorean theorem, we have;

13^2 = 5^2 + h^2

Find the square

169 = 25 + h^2

collect like terms

169- 25 = h^2

h^2 = 144

Find the square root of both sides

h =√ 144

h = 12

Let's find the area

Area = 10 × 12/2

Area = 120/2

Area = 60 square units.

Thus, the area of the isosceles triangle is 60 square units

Since each response is distinct, the odds of correctly predicting each response is 1/3× 1/3× 1/3, or 1/27.

Probability is the ability to happen. The occurrence of random events is the subject of this branch of mathematics. The value is expressed as a number between 0 and 1.

For instance, when a coin is tossed into the air, a Head or Tail are two possible results.

Hence, the term "probability" is most commonly used to refer to the likelihood that a specific event (or group of events) will occur, either as a linear scale from 0 (impossibility) to 1 (certainty) or as a percentage between 0 and 100%. Statistics is the study of events subject to probability.

To solve for distance use the formula for distance d = st, or distance equals speed times time.

distance = speed x time

Rate and speed are similar since they both represent some distance per unit time like miles per hour or kilometers per hour. If rate r is the same as speed s, r = s = d/t. You can use the equivalent formula d = rt which means distance equals rate times time.

distance = rate x time

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time.

speed = distance/time

To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

time = distance/speed

let say they will meet after time t.

distance covered by first boat = velocity of boat × time= 8.5t

distance covered by second boat= 5.5t

distance between both boats = 35km.

by equating both the distance

35km = 8.5t+5.5t

35km = 14t

t= 35÷14 =2.5 hour= 9020.618 seconds.

The Image of the point W(7,3) after the translation is W'(5,6),hence the x-coordinate of the translated point is 5

Translation is used in co-ordinate geometry to find the co-ordinates of an image after moving the point from its original position.

The given point is W(7,3). The point is translated 2 units to the left and 3 units upwards. Hence the new coordinates of the point is given by:

W(7,3)→W'(5,6)

The corresponding growth factor of +500% is 6

The formula for the annual rate of change is

                            1 ± r           (1)

where r = rate of change

and ± sign depends upon whether it is a growth or decay factor. If it is growth factor then it is plus sign otherwise negative sign.

According to the question we have been given the growth that is +500%. Since there is plus sign therefore it is a growth factor.

Thus, r = + 5

Putting this value in equation (1) we get

The domain of the relation is {1, 2, 3, 4, 5} and the range of the relation is {0.75, 1.50, 2.25, 3.00, 3.75}

As per the question statement, the total cost for cars entering President George Bush Turnpike at Beltline Road is related to the number of cars entering the turnpike at Beltline Road. The costs of different numbers of cars entering the turnpike at Beltline Road are as follows: 1 car, $0.75; 2 cars, $1.50; 3 cars, $2.25; 4 cars, $3.00; 5 cars, $3.75.

Ordered pair : {(1,0.750 , (2,1.50) , (3,2.25) , (4,3.00) , (5,3.75)}

Domain is the set which consists of all the first elements of all the ordered pair of the given relation, therefore Domain is {1, 2, 3, 4, 5}.

Range is the set which consists of all the second elements of all the ordered pair of the given relation, therefore Range is {0.75,1.50,2.25,3.00,3.75}

Domain of f + g ( x) = R and f - g ( x) = R

Given :

F(x) = 2x^2 + 8  and g(x) = x-3

From this, we get to know that f(x) and g(x) assume real values for all values of x.

Hence, domain (f)= Real(R) and domain (g)= real ( R ) .

Therefore D (f) and D(g) are Real Number

Now,

A >   (f + g ) : R ----> R is given by (f + g) (x)

       = f(x) + g(x) = 2x^2 + 8 + x- 3

                             = 2x^2  + x + 5

Hence, domain ( f + g ) = Real ( R )

B >    (f – g) : R---> R is given by ( f-g ) (x)

= f(x) – g(x)  = 2x^2 + 8 – ( x – 3)

                    = 2x^2 -x + 11

Hence, domain ( f - g ) = Real ( R )  .
