Answer:

2/3

Step-by-step explanation:

log_{27}(9)

Let x= log_{27}(9)

Convert it into exponential form

 x= log_b(a) can be written as b^x= a

x= log_{27}(9) can be written as {27}^x= 9

27 is 3 times 3 times 3 . its 3^3

9 is 3 times 3 . its 3^2

{27}^x= 9

{3^3}^x= 3^2

{3}^{3x}= 3^2

Base are same so we equate the exponents

3x= 2

Divide both sides by 3

x= 2/3

Manuela solved the equation 3−2|0.5x+1.5|=2 for one solution. Her work is shown below. 3−2|0.5x+1.5|=2 −2|0.5x+1.5|=−1 |0.5x+1.5
forsale [732]

Answer:

x=-4

Step-by-step explanation:

The given equation is

3-2|0.5x+1.5|=2

Subtract 3 from both sides.

3-2|0.5x+1.5|-3=2-3

-2|0.5x+1.5|=-1

Divide both sides by -2.

\dfrac{-2|0.5x+1.5|}{-2}=\dfrac{-1}{-2}

|0.5x+1.5|=0.5

If |x|=a, then x=a or x=-a.

0.5x+1.5=\pm 0.5

Case 1: 0.5x+1.5=0.5

Subtract 1.5 from both sides.

0.5x=0.5-1.5

0.5x=-1

Divide both sides by 0.5.

x=-2

Case 2: 0.5x+1.5=-0.5

Subtract 1.5 from both sides.

0.5x=-0.5-1.5

0.5x=-2

Divide both sides by 0.5.

x=-4

Therefore, one solution is x=-2 and other solution is x=-4.

What is the mean of Variable B?
kherson [118]
Okay, for variable B you have the data points:
1, 2, 3, 5, 6, 6, 7, 7, 10, and 10. 
What you need to do to find the mean (or average) is add all the data up and divide by how many pieces of data you had. So, the sum of all the points is 57. There are 10 points overall.
57/10 is 5.7
Your average for variable B is 5.7
