Answer:

The answer is a = 99

Step-by-step explanation:

We can solve this using ratios

First we set up the equation:

$\frac{a}{90}= \frac{110}{100}$

Then cross-multiply:

$100 * a = 90 * 110$

Simplify:

$100 * a = 9,900$

Divide both sides by 100:

$a = 99$

Ta-Da! The answer is a = 99

Hope this helps! :)

Find the equation of a line containing the given point and slope (10,5); m=9/20

ohaa [14]

$\bf \begin{array}{lllll}
&x_1&y_1\\
% (a,b)
&({{ 10}}\quad ,&{{ 5}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{9}{20}
\\\\\\
% point-slope intercept
y-{{ y_1}}={{ m}}(x-{{ x_1}})\implies y-5=\cfrac{9}{20}(x-10)\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}
\\\\\\
y-5=\cfrac{9}{20}x-\cfrac{9}{2}\implies y=\cfrac{9}{20}x-\cfrac{9}{2}+5\implies y=\cfrac{9}{2}x+\cfrac{1}{2}$

sasho [114]

Answer:

Predicted value YHat is a symbol used to represent the predicted equation for a line of best fit in a linear regression. The equation usually take the form of 'a' as the y- intercept and 'b' as the slope of the graph. It is calculated from estimated regression equations for the line of best fit.

While outcome of experiment is the total of all possible results from an experiment.
