Determine the mean of the data. Round to the nearest tenth. 6, 9, 15, 22, 30, 36

pshichka [43]

To find the mean you add all the numbers and divide it by the amount of numbers there is so add
6+9+15+22+30+36=118
there is 6 number so divide 118 by 6
118/6=<span>19.6666666667 rounded to the nearest tenth it would be 20
So your mean would be 20
let me know if you have any questions</span>

$\bf \begin{array}{clclll}
3^{1001}&\qquad &4^{1002}\\

\end{array}\\\\
-----------------------------\\\\
(a+b)^2-(a-b)^2\implies (a^2+2ab+b^2)-(a^2-2ab+b^2)
\\\\\\
a^2+2ab+b^2-a^2+2ab-b^2\implies 2ab+2ab\implies 4ab
\\\\\\
now\qquad 4(3^{1001})(4^{1002})=k12^{1001}\qquad 
\begin{cases}
12^{1001}\\
(4\cdot 3)^{1001}\\
4^{1001}\cdot 3^{1001}
\end{cases}$

$\bf \\\\\\
4(3^{1001})(4^{1002})=k(4^{1001}\cdot 3^{1001})\implies \cfrac{4(3^{1001})(4^{1002})}{4^{1001}\cdot 3^{1001}}=k
\\\\\\
4\cdot \cfrac{3^{1001}}{3^{1001}}\cdot \cfrac{4^{1002}}{4^{1001}}=k\implies 4\cdot 4^{1002}4^{-1001}=k\impliedby

4\cdot 4^{1002-1001}=k\implies 4\cdot 4^1=k\implies 16=k$

One number is 5 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 779,

AlladinOne [14]

Answer:

Step-by-step explanation:

x - the first number

One number is 5 times a first number:

5x - "one" number (the second number)

A third number is 100 more than the first number:

x + 100 - the third number

x + 5x + x+100 - the sum of the three numbers

x + 5x + x+100 = 779

-100 -100

7x = 679

÷7 ÷7

x = 97

5x = 5•97 = 485

x+100 = 97 + 100 = 197

Check:

97 + 485 + 197 = 779
