Answer:

Given data, first determine which is the independent variable, x, and which is the dependent variable, y. Enter the data pairs into the regression calculator. Substitute the value for one variable into the equation for the regression line produced by the calculator, and then predict the value of the other variable.

Step-by-step explanation:

Enter data into the regression calculator.
Determine the regression equation.
Substitute the correct value for x or y into the equation.
Simplify to find the value of the other variable.

Courier charges for packages to a certain destination are 65 cents for the first 250 grams and 10 cents for each additional 100

lukranit [14]

Answer:

1050 g < weight ≤ 1150 g

Step-by-step explanation:

Let w represent the weight of the package in grams. The the number of 100-gram increments after the first 250 grams is given by ...

⌈(w-250)/100⌉ . . . . . . . where ⌈ ⌉ signifies the ceiling function

and the charges for a package exceeding 250 grams will be ...

0.65 + 0.10⌈(w -250)/100⌉ = 1.55

0.10⌈(w -250)/100⌉ = 0.90 . . . . . . . . subtract 0.65

⌈(w -250)/100⌉ = 9 . . . . . . . . . . . . . . . divide by 0.10

8 < (w-250)/100 ≤ 9 . . . . . . . . . . . . . . meaning of ceiling function

800 < w -250 ≤ 900 . . . . . . . . . . . . . multiply by 100

1050 < w ≤ 1150 . . . . . . . . . . . . . . . . . add 250

The weight in grams could be greater than 1050 and at most 1150 for a charge of $1.55.

Factor completely x2 − 7x + 18

zubka84 [21]

x2 − 7x + 18
is prime

there is no way you can make two numbers multiply to get positive 18 and add to get negative 7

(x − 9)(x − 2) = x^2 - 11x + 18
(x − 9)(x + 2) = x^2 -7x - 18
(x + 9)(x + 2) = x^2 +11x + 18

If an item that costs $45 sold for a 15% discount, how much do you spend on it? Commission is a % of sales.

Stells [14]

Answer:

You pay $38.25 after the discount is applied

Step-by-step explanation:

First take 15% of 45 by multiplying 45 by 0.15 (which is 15% as a decimal)

0.15 * 45 = 6.75

Subtract 6.75 from $45 and then you get $38.25!

Hope this helps! Good luck on your courses!
