Answer:
Step-by-step explanation:
4+3+5= 12 marbles
3/12 * 2/11 = 6/132 = 4.5%
Median: Put the list in order from least to greatest.
$20, $20, $23.50, $25, $26.50
$20, $23.50, $25
$23.50 is the median. I took one from each side until I had one left.
Mean: Get the sum of them all and then divide by the number of earnings ( in this case )
$25 + $26.50 = $51.50 $51.50 + $20 = $71.50 $71.50 + $23.50 = $95
$95 + $20 = $115 $115/5 = $23
$23 is the mean.
Mode: Is the one that finds the frequency or in lamen terms it is the number which appears most often.
There's no steps for finding the expect counting how many times that number appeared.
$20 is the mode.

Answer:
b 5.2 *10-4
Step-by-step explanation:
.00052
We are moving the decimal 4 places to the right to make it in scientific notation. This puts it in the form a* 10^b a must be between 1 and less than 10 and b is the number of places we moved it. It we move it to the left it is positive and to the right it is negative.
5.2 *10-4
If I pick 10, then 2(10)+13=33
If I pick 15, then 2(15)+13=43
If I pick 12, then 2(12)+13=37
