y=-3x+8 determine the y-value of each ordered pair based on the given x-value

Based on the given points on the graph, the equation for the line of best fit or the trend line is y = 1.874x + 3.656

Due to the fact that the points on the graph are not on a straight line, the least squares method can be used to find the line of best fit equation.

Using a linear regression calculator, you can find the equation of the trend line by inputting the values of y and x in the graph.

When run through a linear regression calculator, the result will be:

y = 1.874x + 3.656

The question for this information:

The cost of buying 3 airline tickets at a promotional discount of 20% is 330 dollars. Find the regular cost of 1 ticket.

Discounts and allowances are price reductions from a product's or service's base price.

Discount is calculated by subtracting the sell price of an article from its Marked price.

The given conditions in the question are

So from the above information we can see that if the price of a ticket is c dollars then the discounted price of 1 ticket will be (c - 0.2c).

Total price of 3 tickets =3(c - 0.2c)

but the total price is 330 dollars

Therefore:

3(c - 0.2c) =330

or, 2.4c=330

or, c=330÷2.4

or, c=137.5 dollars

Hence the regular price of each ticket is 137.50 dollars.

The monthly payment to Craig is $ 3093.75

Given,

The payment got by Craig for his job = $ 18.75 per hour

Weekly working hours of Claig:

Week 1 = 37 hours

Week 2 = 47 hours

Week 3 = 42 hours

Week 4 = 39 hours

We have to find the total monthly payment of Craig:

That is,

Week 1 + Week 2 + Week 3 + Week 4

For getting the weekly salary, we have to multiply hourly payment with hours worked:

So,

Week 1 = 37 × 18.75 = 693.75

Week 2 = 47 × 18.75 = 881.25

Week 3 = 42 × 18.75 = 787.5

Week 4 = 39 × 18.75 = 731.25

Now calculate the total monthly payment:

That is,

693.75 + 881.25 + 787.5 + 731.25 = 3093.75

Therefore,

The monthly payment to Craig is $ 3093.75

The monthly instalment amounts forms an (a) Arithmetic Progression with common difference 3. (b) Phillips takes 60 months to settle the loan. (c) The sum of the loan is $7410 .

A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

The n-th term of an arithmetic progression is given by:

aₙ = a + ( n - 1 ) d

Where a is the first term and d is the common difference .

(a) Amount of money repaid in the first month = $35

Amount of money repaid in the second month = $38

Amount of money repaid in the third month = $ (38+3) = $ 41

Therefore 41  -38 = 3 and 38 - 35 = 3 . So we see that each monthly instalment is increasing by 3 and the difference between each installment is 3

Therefore the numbers are in an arithmetic progression whose common difference is 3 .

(b) Given the final monthly installment is $ 212

Let us consider that after this is the installment for the n-th month.

∴ aₙ =212 , a= 35 and d=3

Putting the values in the equation of the n-th term of an AP we get:

aₙ = a + ( n - 1 ) d

or, 212 = 35 +(n-1)3

or, 212 - 35 + 3 = 3n

or, n = 60 months

Therefore Phillips takes 60 months to settle the loan.

(c) The formula for the sum of all terms of an AP is given by:

S = (n / 2 ) ( a + aₙ )

or, S = (60/2) × (35+212)

or, S = 30 × 247

or, S = 7410

Perimeter of rectangle= 2(width) +2(length)

Substitute the given information into the formula:

92= 2(2x +3) +2(x +7)

Expand:

92= 4x +6 +2x +14

The length of the smallest, medium and the longest piece of wood are 7.625, 15.25 and 38.125 inches.

The wood is 61 inches and it is divide into 3 pieces.

The longest piece is 5 times the length of the smallest piece.

The medium piece less than 2 times the length of the smallest.

let

z = length of the smallest piece of wood

longest piece = 5z

medium piece = 2z

The equation to represent the total piece together is equal to 61 inches.

z + 5z + 2z = 61

Therefore, the length of each wood piece can be calculated as follows:

z + 5z + 2z = 61

8z = 61

z = 61 / 8

z = 7.625 inches

longest piece = 5(7.625) = 38.125 inches

medium piece = 2(7.625) = 15.25 inches

Therefore, the length of the smallest, medium and the longest piece of wood are 7.625, 15.25 and 38.125 inches.

The positive integer between 1 and 100 that cannot be represented as a whole percent are 8, 15, 36 and many more.

The class has 99 students.

One student of the class is 1% of the class when rounded to the nearest whole percent. The actual percentage of one student is 1 / 99 × 100 = 100 / 99 = 1.0101010101%

99 of the students represents 100% of the students.
