Find the median number of magazines purchased in a store by 6 customers. 1, 7, 4, 2, 3, 4.

Orlov [11]

The median is the middle number when the numbers are put in ascending order (lowest to highest)

1, 2, 3, 4, 4, 7

The middle numbers are 3 and 4. The number between 3 and 4 is thus the median - this number is 3.5

Answer: $x=21.75$

Step-by-step explanation:

You need to convert from mixed number to decimal number.

In order to do this, you can follow the steps shown below:

1. You must divide the numerator of the fraction by the denominator of the fraction.

2. Now you must add the quotient obtained to the Whole number part.

Then, you get:

$7\frac{1}{4}=7+0.25=7.25$

Then, the scale image that maps "Figure A" onto "Figure B" is:

$1:7.25$

Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure A" by $7.25$ .

Therefore, the result is:

$x=(3)(7.25)\\\\x=21.75$
