Winona’s bowling scores for the past nine weeks are 195, 180, 195, 212, 208, 231, 179, 246, and 195. Find the mean, median, and

Answer: Mean = 204.6 , Median = 195 and mode =195

Step-by-step explanation:

The given data for Winona’s bowling scores for the past nine weeks : 195, 180, 195, 212, 208, 231, 179, 246, 195.

The formula to find Mean is given by :-

$\text{Mean}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}\\\\=\dfrac{1841}{9}=204.555555556\approx204.6$

For median , first we arrange data values in order as

179, 180, 195, 195, 195, 208, 212, 231, 246

Since the number of data values is 9 (odd).

∴ Median = Middle most data value = 195

Also, Mode = Most occurring data value = 195

Simplify completely 12 times x to the third power minus 4 times x to the 2nd power plus 8 times x all over negative 2 times x. (

jok3333 [9.3K]

So we want to simplify
$\frac{12 {x}^{3} - 4 {x }^{2} + 8x }{ - 2x}$
We split the numerators,

$= \frac{12 {x}^{?3} }{ - 2x} - \frac{4x {}^{2} }{ - 2x} + \frac{8x}{ - 2x}$
$= - 6 {x}^{2} + 2x - 4$
The correct answer is B.
