How can one determine the median of a data set?
rjkz [21]

Answer:

A

Step-by-step explanation:

The median value on a data set is the value that accumulates 50% of the values at its left and the other 50% at its right. In other words, it is the value that divides the data set in two halves. Lets see each option and find this value:

B: By doing it we are finding the mode, the value that is repeated most. This is incorrect!

C: By doing this we are finding the mean, the average or the arithmetic mean. This is incorrect!

D: This gives us the range, not the median. This is incorrect!

Finally, A is correct, as this is what we said at the beginning of the text. Ordering the values and finding the one the splits the data set in 2 equal parts is the median.

Factor 6X to the fourth power minus 5X squared +12 X squared -10 by grouping what is the resulting expression
algol13

Answer:

(6x^2 - 5)(x^2 + 2).

Step-by-step explanation:

6x^4 - 5x^2 + 12x^2 - 10

= 6x^4 + 12x^2 - 5x^2 - 10

= 6x^2(x^ + 2) - 5(x^2 + 2)

(x^2 + 2) is common so we have:

(6x^2 - 5)(x^2 + 2).

A rectangle is 32m by 8m is similar to a rectangle 4m by x m. Find the 2 possible values of x .
Stella [2.4K]
<h3>Answers:</h3><h3>x = 1 or x = 16</h3>

======================================

Work Shown:

Draw out a rectangle that is 32 units wide horizontally and 8 units tall vertically.

Then draw out another rectangle that is 4 meters wide horizontally and x meters tall vertically.

The horizontal and vertical sides pair up to form these fractions: 32/4 and 8/x

Set the fractions equal to one another. Solve for x

32/4 = 8/x

32x = 8*4 ... cross multiply

32x = 32  

x = 32/32 ... divide both sides by 32

x = 1

-----------------------

Somewhere else on your paper, draw the same 32 by 8 rectangle to make 32 the horizontal component

Next to this rectangle, draw a rectangle that has x as the horizontal part and 4 as the vertical. Note the swap here.

We now have this equation to solve for

32/x = 8/4

once again, note the swap

Let's solve for x

32/x = 8/4

32*4 = 8*x

128 = 8x

8x = 128

x = 128/8

x = 16
