Step-by-step explanation:

Finding the median

The median is the number that is located in the middle of the set of numbers. First you count the number of X's, which is 26. This means that the median is in between number 13 and 14, which is 2 and 3 in this number set. Then you average the two numbers (\frac{2+3}{2}) to get 2.5.

Finding the mean

The mean is the average of all of the numbers located in the set. First, you add up all of the numbers.

5(0) + 5(1) +3(2) + 2(3) +4(4) + 1(5) + 2(6) + 2(7) + 1(8) + 1(9) = 81

After, you divide by how many numbers there are in the set, which as we found earlier, is 26

\frac{81}{26} = 3.12

Answer:

so from looking at this we can see there is

0=5

1=5

2=3

3=2

4=4

5=1

6=2

7=2

8=1

9=1

now we have to add them up

5+6+16+5+12+14+8+9=75

and now we have to add up the total plots on the chart

5+5+3+2+4+1+2+2+1+1=26

now we divide

75 divided by 26=2.88461538462

so 2.9 is the mean

now we add up the number from least to greatest

0,0,0,0,0,1,1,1,1,1,2,2,2,4,4,4,4,5,6,6,7,7,8,9

so the medien is 4

Hope This Helps!!!

Divide 7/24 by 35/48 and reduce the quotient to the lowest fraction
tiny-mole [99]
\frac{7}{24} ÷ \frac{35}{48}
Multiply \frac{7}{24} by the reciprocal of \frac{35}{48}, which is \frac{48}{35}

=\frac{7}{24} × \frac{48}{35}
=\frac{336}{840}

We can simplify it further:
The greatest common factor here is 168
\frac{336/168}{840/168}

=\frac{2}{5}
