The only thing you need to do is 'cross-multiply'

Take the top of fraction 1 and multiply it to the bottom of fraction 2, and take the bottom of fraction 1 and multiply it to the top of fraction 2.

Then you will get a nice and easy equation to solve!

Answer:

Mason

Step-by-step explanation:

It is simply a matter of which line is steepest. Charlie's graph is the steepest but the units the students plotted by are not the same. So on Mason's graph, if u plot a point high on the line u see he reads the most words in the least time.

Hope this helps,

Evaluate the expression for the given value of the variable. |b| + b^3 ; b = -2, please show work!

Katen [24]

So b=-2 so you plug b in

l(-2)l + (-2)^3.

The absolute value of -2 is just 2 so now it is

2 + (-2)^3.

-2 * -2 is 4 but 4 * -2 is -8. So 2 + (-8) or 2 - 8 which comes to equal (-6) or negative six.

Fed [463]

Answer:

1. $29.4 million

2. 145.24

3. 145.24

4. 12.05

5. D. No, because the sample is not representative of the whole population.

Step-by-step explanation:

1. The computation of range of the sample data is shown below:-

Range of the sample data = Maximum value - Minimum value

= 42 - 12.6

= $29.4 million

2. For the computation of variance of the sample data first, we need to find out the mean which is shown below:-

Mean = $\frac{(42 + 40 + 39 + 32 + 21 + 18 + 16 + 14 + 13.7 + 12.6) }{10}$

= 24.83

The Variance of the sample data

= $\frac{(42 - 24.83)^2 + ..... + (12.6 - 24.93)^2}{10 - 1}$

= $\frac{1307.161}{9}$

= 145.24

3. The computation of the standard deviation of the sample data is shown below:-

The Standard deviation of the sample

= $\sqrt{145.24}$

= $12.05155592

or

$12.05

4. No, as the sample does not represent the whole population.
