Hey there :)

( a - b )( a² + ab + b² )
Let us distribute ( a - b ) into the other

a ( a² ) + a ( ab ) + a ( b² ) - b ( a² ) - b ( ab ) - b ( b² )
a³ + a²b + ab² - a²b - ab² - b³

We can further simplify
a²b - ab² = 0
ab² - ab² = 0

a³ - b³

You can see in the picture which I have attached. It is the 8th formula

A number n plus 7 is less than or equal to 9
Mazyrski [523]
We need to change the English writing into an inequality.
We know that a number "n" added to 7 is less than or equal to 9.
This can be written as follows:
n + 7 <span>≤ 9

Now, we will isolate the "n" at one side of the inequality. We will do this by subtracting 7 from both side as follows:
n + 7 - 7 </span><span>≤ 9 - 7
n </span><span>≤ 2</span>

Find the mean of the data
Triss [41]
<h3>Answer:  6.282</h3>

Explanation:

Refer to the table below. I've added a third row where I multiplied each x value with its corresponding frequency value f. We can refer to this row as the xf row.

Once we know the xf values, we add them up to get 245.

We'll then divide that result over the sum of the frequency values (add everything in the second row). The sum of the frequency values is 39.

So the mean is approximately: 245/39 = 6.282051 which rounds to 6.282

Notice that this mean value is fairly close to the x value which has the highest frequency.
