√a x √b =√axb so find 2 numbers that multiple to make the number (1 must be a square number)

√90 can be split into √9 x √10 and √9 is 3 so is 3√10 and the next questions are solved the same

√306 is 3√34

√73 is 3√8

√236 is 2√59

√3600 is 60

√5120 is 8√80

Answer:

$m=\frac{332}{182}=1.824$

$b=\bar y -m \bar x=43.615-(1.824*21)=5.311$

So the line would be given by:

$y=1.824 x +5.311$

Step-by-step explanation:

We assume that the data is this one:

x: 15 16 17 18 19 20 21 22 23 24 25 26 27

y: 33 34 33 36 36 47 52 51 41 50 49 50 55

Find the least-squares line appropriate for this data.

For this case we need to calculate the slope with the following formula:

$m=\frac{S_{xy}}{S_{xx}}$

Where:

$S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}$

$S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}$

So we can find the sums like this:

$\sum_{i=1}^n x_i =273$

$\sum_{i=1}^n y_i =567$

$\sum_{i=1}^n x^2_i =5915$

$\sum_{i=1}^n y^2_i =25547$

$\sum_{i=1}^n x_i y_i =12239$

With these we can find the sums:

$S_{xx}=\sum_{i=1}^n x^2_i -\frac{(\sum_{i=1}^n x_i)^2}{n}=5915-\frac{273^2}{13}=182$

$S_{xy}=\sum_{i=1}^n x_i y_i -\frac{(\sum_{i=1}^n x_i)(\sum_{i=1}^n y_i)}{n}=12239-\frac{273*567}{13}=332$

And the slope would be:

$m=\frac{332}{182}=1.824$

Nowe we can find the means for x and y like this:

$\bar x= \frac{\sum x_i}{n}=\frac{273}{13}=21$

$\bar y= \frac{\sum y_i}{n}=\frac{567}{13}=43.615$

And we can find the intercept using this:

$b=\bar y -m \bar x=43.615-(1.824*21)=5.311$

So the line would be given by:

$y=1.824 x +5.311$
