Roberto took a sample of 5 recent matches for his favorite soccer team. Here is how many goals the team scored in each match: 0,
kap26 [50]

<em>Roberto </em><em>did not include </em><em>the </em><em>first term</em><em> of the numerator (0-2)^2 in his calculation.</em>

The mean of the data is also known as average.

Given the set of data 0, 2, 1, 2, 5

Mean = 0+2+1+2+5/5

Mean = 10/5

Mean = 2.0

To get the standard deviation, we will use the SD formula as shown:

\sigma=\sqrt{\frac{\sum (x-\overline x)^2}{N} }

\sigma =\sqrt{ \frac{(0-2)^2+(2-2)^2+(1-2)^2+(2-2)^2+(5-2)^2}{5}}\\ \sigma = \sqrt{\frac{4+0+1+0+9}{5}} \\\sigma =   \sqrt{\frac{14}{5} }\\\sigma =  1.673

Comparing this with Roberto's calculation, we can see that <em>Roberto </em><em>did not include </em><em>the </em><em>first term</em><em> of the numerator (0-2)^2 in his calculation.</em>

Dima020 [189]

Answer:

g(2w)=6w+8

Step-by-step explanation:

We know that g(z)=3z+8

And we want to find g(2w)

So, we will simply substitute <em>2w</em> for <em>z</em>. This yields:

g(2w)=3(2w)+8

Distribute. Therefore:

g(2w)=6w+8
