You would need to give us the data set to answer this question. I'm assuming this is a stats question which means I'd need to see what set of data you are working with to determine if the mean or median is best to describe the center. The meadian is resistant to outlying values while the mean is not. Therefore the meadian is a better describer for skewed distributions. Whenever you have outliers the dataset is skewed. Take a look at the shape of the data. Does it look skewed? You can make a simple graph with the data points to determine if there are outliars if you aren't able to tell just from looking at the data. (Again I don't know what data you are working with, but I hope this helped)

The endpoints of CD are C(1, -6)and D(7,5). Find the coordinate of the midpoint, M

yuradex [85]

Answer:

(4, - 0.5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ $\frac{x_{1}+x_{2} }{2}$ , $\frac{y_{1}+y_{2} }{2}$ ]

Here (x₁, y₁ ) = C(1, - 6) and (x₂, y₂ ) = D(7, 5) , then

midpoint = ( $\frac{1+7}{2}$ , $\frac{-6+5}{2}$ ) = $\frac{8}{2}$ , $\frac{-1}{2}$ ) = (4, - 0.5 )

SOMEBODY HELP ME WITH THESE PLEASE! I really need the help like NOW PLS!

93. $g(n) = n - 4$
$f(n) = 2n^2 - 5n$

then $g(n) +f(n) = (n-4) + (2n^2 - 5n)$
                                $= n - 4 + 2n^2 - 5n$
                                $= 2n^2 -5n + n - 4$
                                $= 2n^2 - 4n -4$

95. $f(n) = -n+3$
      $g(n) = n^3 + 3n$
Then $f(n) . g(n) = (-n+3) . (n^3 + 3n)$
                                 $= -n^4 + 3n^3 - 3n^2 + 9n$

97. $f(x) = 3x+1$
$g(x) = 2x$
For finding f(g(x)) we will plugin value of g(x) in place of x in f(x).
$f(g(x)) = 3*(2x) + 1$
                  $= 6x + 1$

99. $f(n) = n - 3$
$g(n) = 2n^2 - 3n$

$g(-7) = 2*(-7)^2 - 3 * (-7) = 2* 49 + 21 = 98 + 21 = 119$
$f(g(-7)) = 119 - 3 = 116$

A rule for nth term of -2 , -5/4 ,-1/2,1/4

miv72 [106K]

Answer:

Step-by-step explanation:

This is an arithmetic sequence

a1 = -2

Difference = 2nd term - first term

$=\frac{-5}{4}-[-2]\\\\=\frac{-5}{4}+2\\\\=\frac{-5}{4}+\frac{2*4}{1*4}\\\\=\frac{-5+8}{4}=\frac{3}{4}$

$a_{n}=a+(n-1)d\\\\=-2+(n-1)*(\frac{3}{4})\\\\=-2+\frac{3}{4}n-\frac{3}{4}\\\\=\frac{-2*4}{1*4}-\frac{3}{4}+\frac{3}{4}n\\\\=\frac{-8-3}{4}+\frac{3}{4}n\\\\=\frac{-11}{4}+\frac{3}{4}n$

student were asked to choose their favorite food and 5/6 chose either pizza or tacos if 2/6 of the students chose pizza what fra

Julli [10]

Answer:

3/6 or 1/2

Step-by-step explanation:

the amount that chose pizza = 2/6

5/6 = the amount that chose pizza + the amount that chose tacos

5/6 = 2/6 + the amount that chose tacos

the amount that chose tacos = 5/6 - 2/6

the amount that chose tacos = (5-2)/6

the amount that chose tacos=3/6=1/2
