Hey, I know you already found the median, but if you need help with anything else like that I'll show you!

Mean:

Step 1: Add up all data values to get the sum

Step 2: Count the number of values in your data set

Step 3: Divide the sum by the count

Mode:

Mode is the value or values in the data set that are the most common. To remember what mode is, think of most. Mode, Most.

Range:

The Range is the difference between the lowest and highest values. So, if we had a data set that read 5 5 3 6 9, you would have to find the lowest and highest number. For this set, thats 3 and 9. subtract them to get the sample range. 9 - 3 = 6.

Answer:

The median is 5.

Step-by-step explanation:

To find the median you have to do steps, (they are really easy):

The median is like the middle of the graph so just try finding the middle, ( i could explain this in a different way but it's hard to explain) Hope this helps.

Answer:

Step-by-step explanation:

We'll take this step by step. The equation is

$8-3\sqrt[5]{x^3}=-7$

Looks like a hard mess to solve but it's actually quite simple, just do one thing at a time. First thing is to subtract 8 from both sides:

$-3\sqrt[5]{x^3}=-15$

The goal is to isolate the term with the x in it, so that means that the -3 has to go. Divide it away on both sides:

$\sqrt[5]{x^3}=5$

Let's rewrite that radical into exponential form:

$x^{\frac{3}{5}}=5$

If we are going to solve for x, we need to multiply both sides by the reciprocal of the power:

$(x^{\frac{3}{5}})^{\frac{5}{3}}=5^{\frac{5}{3}}$

On the left, multiplying the rational exponent by its reciprocal gets rid of the power completely. On the right, let's rewrite that back in radical form to solve it easier:

$x=\sqrt[3]{5^5}$

Let's group that radicad into groups of 3's now to make the simplifying easier:

$x=\sqrt[3]{5^3*5^2}$ because the cubed root of 5 cubed is just 5, so we can pull it out, leaving us with:

$x=5\sqrt[3]{5^2}$ which is the same as:

$x=5\sqrt[3]{25}$

The country of Freedonia has decided to reduce its carbon-dioxide emission by

Goshia [24]

Answer:

$\\E(t) =40(0.65)^{t}$

Step-by-step explanation:

Since the country wants to reduce the emission by the percentage each year, the function will be decaying function. The formula of decaying function will look like this

$E(t) =E_{0} (1-r)^{t}\\$

Where

E(t) = the number of emission after t years

E0= the number of initial emission= 40 million tons

r=rate of growth/decay = 35%= 0.35

t= time in years

If we put the number, the equation will be:

$E(t) =E_{0} (1-r)^{t}\\E(t) =40(1-0.35)^{t}\\E(t) =40(0.65)^{t}$
