Answer:

Step-by-step explanation:

Mean:  Add them all up then divide that sum by how many there are.

Median:  They are in number order, so that makes median and mode very very nice.  For an odd number of points, you choose the middle point, for an even number of points (which we have) take the two and find the average of those two.  That is, add the two up then divide them by two, it's basically taking their mean.  since there are 20 you take the 10th and 11th numbers.

Mode:  Again, super easy since they are in number order, just look for the number that appears the most.  If none do, there is no mode.  Hint, there is a number that appears twice.

What is the average rate of change from x = 0 to x = 4?
hammer [34]
1) find the corresponding y values for when x = 0 and when x = 4,
when x = 0, y = 4
when x = 4, y = 4

the coordinates are (0,4) and (4,4)

2) to calculate the average rate of change, find the slope of the two points:

(0,4) (4,4)

(change in y) 4 - 4 = 0
(change in x) 4 - 0 = 4

0/4 = 0

the average rate of change is 0!

You work with 3 other students on a project for science class. Your group
aleksandrvk [35]

Answer:

350 points are possible

Step-by-step explanation:

You take 329 divided by 94% or .94 to get 350.

100% of 350 is 350

To double check, 94% of 350 is 329 & 6% of 350 is 21.  329 +21 = 350

Does anyone know the answer to this? I can't understand why it isn't -7.​
faltersainse [42]

The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.

<h3>How to calculate the value?</h3>

From the information given, it should be noted that we simply want to calculate the value of x.

This will be:

18x + 9∆x - 7

It was stated that ∆x = 0

Therefore, we'll put this into the equation.

This will be:

18x + 9∆x - 7

= 18x + 9(0) - 7

= 18x -7

In 1990 the average family income was about $ 39 , 000 , and in 2010 it was about $ 70 , 768 . Let x = 0 represent 1990, x = 1 r
iren2701 [21]

Answer:

<em />f(x) = 1588.4x + 39000<em />

f(15) = 62826

Step-by-step explanation:

Given

In 1990; Income= $39000

In 2010; Income= $70768

Solving (a): An equation in form of f(x) = ax + b

First, we need to determine the slope, a

a = \frac{y_2 - y_1}{x_2 - x_1}

Taking y as income and x as year index.

When x = 0; y = 39000

When x = 20; y = 70768

Substitute these values in the above formula

a = \frac{70768 - 39000}{20 - 0}

a = \frac{31768}{20}

a = 1588.4

Next, is to determine the formula using:

y - y_1 = a(x - x_1)

<em>Considering :When x = 0; y = 39000, we have</em>

<em />y - 39000 = 1588.4(x - 0)<em />

<em />y - 39000 = 1588.4x<em />

<em>Make y the subject of formula</em>

<em />y = 1588.4x + 39000<em />

<em />

<em>Express y as a function of x</em>

<em />f(x) = 1588.4x + 39000<em />

Solving (b): Income in 2005

<em>In 2005, x = 15</em>

So:

f(x) = 1588.4x + 39000 becomes

f(15) = 1588.4 * 15 + 39000

f(15) = 62826
