2(7/2)^x = 49/2

Divide both sides by 2:

(7/2)^x = 49/4

I notice that 49/4 can be rewritten as (7/2)^2, so we now have:

(7/2)^x = (7/2)^2

The only way for this to be true is if x = 2.  Thus, we are done.

Find the MAD for this set of data.
Nostrana [21]

Answer:

Hence MAD=0.8

Step-by-step explanation:

<u>MAD-</u>

MAD is also known as Mean Absolute Deviation.

We find MAD by the following steps:

  • Firstly we find the mean of the data
  • Then we subtract each entry from the mean to obtain the deviation
  • Then find the absolute value of the deviation which is also known as absolute deviation.
  • Finally we find the mean of the absolute deviation.

Now we are given a table of the absolute deviation we just need to calculate the mean of the absolute deviation.

The absolute deviation is given as:

1    3    1    0    0    1    0    0    1    1

The mean of this is calculated as:

\dfrac{1+3+1+0+0+1+0+0+1+1}{10}=\dfrac{8}{10}=0.8

Hence, MAD=0.8

Use the order of operations and the digits 2, 4, 6, and 8 to create an expression with a value 2.
Fed [463]

Answer:

8 +  {2}^{2}  - (4 + 6)

Step-by-step explanation:

We want use the order of operations and the digits 2, 4, 6, and 8 to create an expression with a value 2.

The expression is:

8 +  {2}^{2}  - (4 + 6)

The order of operations is PEDMAS

Deal with parenthesis first,

8 +  {2}^{2}  - 10

Next deal with exponent

8 + 4 - 10

No Division and Multiplication so skip to Addition.

12 - 10

Finally subtract to get:

2
