Answer:You can put this solution on YOUR website!

The numbers are between +/- 2 sd s of the mean

With Chebyshev's inequality, at least 3/4 of the numbers would be between these two.

For the one with 3 standard deviations, it would be 8/9.

----------------------

For the second part, this is 3.5 sd s on either side

1/(3.5)^2=0.0816, The fraction is 1/(49/4) or 4/49.

----------------

The second one would be wishing 18/8 or 2.25 sd s and that fraction would be 1/(9/4)^2=1/81/16 or 16/81 or 0.1975.

What is the solution to the equation 4x+16-x=22+6

riadik2000 [5.3K]

Simplifying

4x + 16 + -1x = 22 + 6

Reorder the terms:

16 + 4x + -1x = 22 + 6

Combine like terms: 4x + -1x = 3x

16 + 3x = 22 + 6

Combine like terms: 22 + 6 = 28

16 + 3x = 28

Solving

16 + 3x = 28

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-16' to each side of the equation.

16 + -16 + 3x = 28 + -16

Combine like terms: 16 + -16 = 0

0 + 3x = 28 + -16

3x = 28 + -16

Combine like terms: 28 + -16 = 12

3x = 12

Divide each side by '3'.

x = 4

Simplifying

x = 4

What's the answer to this question= 4(3x + 2) + 2(x + 3)

Serga [27]

Answer:

$\huge{ \boxed{ \bold{ \tt{14x + 14}}}}$

Option E is the best choice.

▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁▁

☯ Question : Simplify

4 ( 3x + 2 ) + 2 ( x + 3 )

☯ Available options :

☐ 12x + 16

☐ 24x + 48

☐ 10x + 2

☐ 14x + 48

☑ 14x + 14

☐ 9x + 5

✎ Step - by - step explanation :

$\sf{4(3x + 2) + 2(x + 3)}$

Distribute 4 through the parentheses

$\dashrightarrow{ \sf{12x + 8 + 2(x + 3)}}$

Distribute 2 through the parentheses

$\dashrightarrow{ \sf{12x + 8 + 2x + 6}}$

Combine like terms. Only coefficients of like terms can be added or subtracted

$\dashrightarrow{ \sf{12x + 2x + 8 + 6}}$

$\dashrightarrow{ \sf{14x + 8 + 6}}$

Add the numbers : 8 and 6

$\dashrightarrow{ \boxed{ \sf{14x + 14}}}$

Hope I helped!

Have a wonderful time ツ
