Which measure of variability provides the most meaningful information about the following set of scores? Set of scores: 12, 12,

Alexus [3.1K]

Answer:

$Median$

Step-by-step explanation:

Median. Median in this case will give the most meaningful information about this data set.

<em>Reason</em>: There is at least one extreme score,32, in the distribution. It is an outlier that has a great effect on the mean:-

$m_9=\frac{148}{9}=16.44\\m_8=\frac{116}{8}=14.5 \ *11.8\% \ drop \ in \ mean.\\Median_9=15\\Median_8=14.5 \ *just \ a \ 3\% \ drop \ in \ median$

Hence median will give the most meaningful info about this data set

Josie spent 4/7 of ten money in her purse on some books, and the rest of the money on 18 markers. Each marker cost $1.20. How mu

NeTakaya

Let's assume money in Josie's purse to begin with as 'x'

There are 18 markers

Each marker cost $1.20

so, we can find total cost of markers

Total cost of markers = ( total number of markers)*(price of each marker)

so, we can plug value

Total cost of markers is

$=18\times 1.20$

$=21.6$ $

now, we are given

Josie spent 4/7 of the money in her purse on some books

the rest of the money on 18 markers

so, rest money is

$=x-\frac{4}{7} x$

$=\frac{3}{7} x$

and this rest money is total cost of markers

so, we can set them equal and then we can solve for x

$\frac{3}{7} x=21.6$

$7\cdot \frac{3}{7}x=21.6\cdot \:7$

$3x=151.2$

$x=50.4$

So, total money in Josie's purse in beginning is $50.4..........Answer

Simplify the following expression. one-fourth(16 – 12x) (1 point) 4 + 3x 4 – 3x 4 + 3 4 – 3

Bad White [126]

Given expression: 1/4 (16-12x).

Solution: We can see that 1/4 is in front of paranthesis.

That represents multiplication of 1/4 with (16-12x)

In order to 1/4 with (16-12x), we need to distribute 1/4 over (16-12x).

On distributing 1/4 over (16-12x), we get

1/4 (16-2x) = 1/4 * 16 + 1/4 * (-12x).

On multiplying 1/4*16, we get 16/4 and 1/4 * (-12x) = -12x/4.

16/4 could be simplify to 4 and -12x/4 could be simplify to -3x.

So, final answer would be 4 - 3x.

Therefore, second option is our correct option, that is 4 - 3x.
