Awnser:

a) Tanya didn’t order them from the smallest number to the biggest number

b) 32.5 i’m not sure if that can be cause it isn’t a whole number i haven’t done mean median mode and rang in a long time sorry

EXPLAINATION:

order your numbers from least to greatest and then start crossing them off from each end if there are two numbers in the middle then add them up and divide them by two in this case we added 32 and 33 it was 65 then I divided 65 by 2 it was 32.5

Triangles A and B are similar.<br> If the slope of Y is 4/5 what's the slope of x?

sdas [7]

Similar triangle Hypotenuse must have similar slopes. If you'll notice, y & x are parallel lines, so they will have equivalent slope

In short, Your Answer would be 4/5

Hope this helps!

Write an equation in point-slope form, y – y1 = m(x – x1), of the line through points (9, –2) and (10, 2). Use (9, –2) as the po

True [87]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 9 &,& -2~) 
% (c,d)
&&(~ 10 &,& 2~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{2-(-2)}{10-9}\implies \cfrac{2+2}{10-9}\implies \cfrac{4}{1}\implies 4
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-2)=4(x-9)\implies y+2=4(x-9)$
