Answer:
<em>Rearrange the numbers first</em>
22, 22, 23, 23, 23, 32, 32, 33, 33
Mean (total average): (22+22+23+23+23+23+32+32+33+33) / 9 = 27
<em>^^ sum of all values divided by number of data values ^^</em>
Median (middle number): 23
Mode (appears most often): 23
Range (largest subtract smallest): 33 - 22 = 11
F(-2)= -11
I hope this helps :)
To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer
V= m/d. When you get questions asking about density/mass/volume draw a triangle just like in the picture i have attached and with your finger cover up the one you are looking for. So to find the equation for volume you cover up volume and you are left with mass divided by density.
