Sarah 's age is ten years more than twice tanya's age. The total of their age is 64 how old is sarah

The range of five numbers is 10, the mean is 13.6, the median is 14,

denis23 [38]

Answer:

8 13 14 15 18.

Step-by-step explanation:

The median (the middle number) is 14 so we have

x x 14 x x where x is a single number with each number being different (as there is no mode).

The mean is 13.6 so we have the total numbers

= 13.6 * 5 = 68.

The 4 numbers left must total 68-14 = 54 and the difference between the highest and lowest is 10.

I sense that the lowest and highest will add up to about 1/2 of 54 so:

Try 8 and 18 for these last 2 numbers

The list would be 8 x 14 x 18.

The 2 numbers left will add up to 54 - 26 = 28 . One of these must be < 14 and the other > 14. 13 and 15 would fit.

So a possible data set is:

8 13 14 15 18.

Function rule and y intercept

stiks02 [169]

to get the equation for any straight line, all we need is two points from it, so hmmm say from this table let's use (2,0) and (6,-8)

$\bf \begin{array}{|r|r|r|r|r|r|} \cline{1-6} days&x&2&4&6&8\\ \cline{1-6} dollars&y&0&-4&-8&-12\\ \cline{1-6} \end{array}~\hfill (\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{-8}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-8}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{2}}}\implies \cfrac{-8}{4}\implies \cfrac{\stackrel{rise}{-2}}{\underset{run}{1}}\implies \stackrel{slope}{-2}$

$\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{-2}(x-\stackrel{x_1}{2}) \\\\\\ \stackrel{~\hfill y-intercept}{y=-2x\stackrel{\downarrow }{+4}}\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}$
