strojnjashka [21]

Answer:

  1. y = 0.937976x +12.765
  2. $12,765
  3. $31,524
  4. the cost increase each year

Step-by-step explanation:

1. For this sort of question a graphing calculator or spreadsheet are suitable tools. The attached shows the linear regression line to have the equation ...

... y = 0.937976x + 12.765

where x is years since 2000, and y is average tuition cost in thousands.

2. The y-intercept is the year-2000 tuition: $12,765.

3. Evaluating the formula for x=20 gives y ≈ 31.524, so the year-2020 tuition is expected to be $31,524.

4. The slope is the rate of change of tuition with respect to number of years. It is the average increase per year (in thousands). It amounts to about $938 per year.

What is the slope of this line
Nostrana [21]

Answer:

m=-3/4

Step-by-step explanation:

First locate two points that are on solid intersections, (-3, 2) and (1, -1).

<u>y2</u><u>-</u><u>y1</u>

Then use x2-x1' where -1 is y2, 2 is y1, 1 is x2, and -3 is x1.

Plug in numbers, <u>-1-2</u><u> </u>= <u>-</u><u>3</u>

1+3 = 4

-3/4 is m (Slope).

An office supply store sells 12 rolls of tape for $29.88. At that rate, which proportion could be used to solve for c, the cost
kobusy [5.1K]

Answer:

$89.64

Step-by-step explanation:

First, you want to find your unit rate.

To do that, simply just divide what you know (cost/amount):

29.88/12

= 2.49

This means that one role of tape costs $2.49.

Now that we know that, you can simply just solve for value "c":

c = 2.49(36)

c = 89.64

The area of a rectangle having breadth 2.6m is 18.33 sq.m. Find the<br> length of rectangle.
ladessa [460]

Answer:

Length = 7.05m

Step-by-step explanation:

Breadth is just a fancy word for width. We know that the width is 2.6 m and the total area is 18.33 m². We also know that the formula for the area of a rectangle is l*w, length times width. Remember, we are looking for l.

Set up an equation: l*w=A

Where:

  • l = Length
  • w = Width
  • A = Area

Plug in the known values.

l*w=A

l * 2.6 = 18.33

Solve for l. Isolate the variable by dividing both sides of the equation by 2.6:

l = 7.05

You can easily check your work by finding l*w now that you know both values. Always remember to put the unit back into your answer! So your final answer should be l=7.05 m
