The mean is affected by outliers

Vlad1618 [11]

Yes it is :)

If there is an outlier on the lower end of the graph the mean will go down. If there is an outlier at the higher end of the graph the mean will go up.

A new sidewalk will be 5 feet wide, 100 feet long, and filled to a depth of 3 inches (0.25 foot) with concrete. How many cub

GarryVolchara [31]

Answer:

4.63 cubic yard.

Step-by-step explanation:

Given,

The length of sidewalk, l = 100 feet,

Width, w = 5 feet,

Depth, h = 3 inches = 0.25 feet,

Thus, the volume of the concrete needed for making the sidewalk,

$V=l\times w\times h$

$=100\times 5\times 0.25$

= 125 cubic feet,

∵ 1 cubic yard = 27 cubic feet,

⇒ 1 cubic feet = $\frac{1}{27}$ cubic yard,

Thus, the quantity of concrete needed = $\frac{125}{27}$ ≈ 4.63 cubic yard.

If m(x) =x+5/x-1 and n(x) =x-3 which function has the same domain as (m.n)(x)

Travka [436]

Answer:

Step-by-step explanation:

m (x) = (x+ 5) / (x -1) and n(x) = x - 3.

$m(x) = \dfrac{x+5}{x-1}$

Hence

$m(n) = \dfrac{n+5}{n-1}$

but n is a function and n = x-3. Now, replace value of n on m (n)

$(m(n))= \dfrac{(x-3)+5}{(x-3)-1}$

simplify it

$(m\bullet n)(x) =\dfrac{x+2}{x-4}\\$

since (m . n) (x) is a fraction function, its domain will be all x such that the denominator is NOT 0. That is

$x-4\ne 0\rightarrow x\ne 4$

among options, only C has the same denominator with $(m\bullet n)(x)$

Hence their domains are the same.
