Helen [10]

Answer:

x² = (x-2) (x+3)

and

x = 6

Step-by-step explanation:

x² = (x-2) (x +3)

x² = x² + 3x - 2x - 6

x² = x² + x - 6

Find the Mean from the line plot. Show your work and explain how you solved using First, Next, and Last.
Musya8 [376]

Answer:

mean is 5

Step-by-step explanation:

<h2>MEAN</h2>

mean is regarded as the average number of items

<h3>mean formula:</h3>

<em>(sum of terms) / (number of terms)</em>

<h3><u /></h3><h3><u>Firstly</u></h3>

the numbers in the data set are :

3,3,3,4,6,6,7,8

they are already arranged in order, so no need to rearrange.

<h3><u>Next </u></h3>

add the numbers together to find the total :

3 +3 +3 +4 +6+ 6+7 +8

= 40

ALSO,

find how many number of terms they are --- this is 8

Last

use the mean formula to solve :

<em>(sum of terms) / (number of terms)</em>

= 40/8

= 5

<h3><em><u>the mean is the 5 </u></em></h3>

Given: f(n) = 3n-5 and g(n) = 2n-1<br>Find: (fog)(5​
laiz [17]

Answer:

22

Step-by-step explanation:

So we have the two functions:

f(n)=3n-5\text{ and } g(n)=2n-1

And we want to find (fog)(5). This is the same as:

(f\circ g)(5)=f(g(5))

So, find g(5) first:

g(5)=2(5)-1\\

Multiply and subtract:

g(5)=10-1=9

So, we can substitute:

f(g(5))=f(9)

Find the value:

f(9)=3(9)-5

Multiply and subtract:

f(9)=27-5=22

So:

(f\circ g)(5)=22

And we're done!
