Median is the middle number and you have to put each set in order like you've done, tick each number off and each side working in: 3,4,-6-,7,8 =6 3,3,-4-,5,5 =4 6,7,-7-,8,9 =7 2,2,-3-,4,6 =3 Mode is the number that shows up the most 3,4,6,7,8= no mode 3,3,4,5,5= 3 and 5 6,7,7,8,9=7 2,2,3,4,6=2
Solution: Here: On 12 gallons of gas 144 miles is travelled. So, for 1 mile : is required. Now, for 240 miles: is required. But, according to question, the tank only contains 6 gallons of gas. So, see needs more (20 - 6) gallons of gas [i.e. 14 gallons of gas].
Let the radius of the bigger circle,R = 6cm Let the radius of the smaller circle, r = 4cm Area of the shaded region= area of the bigger circle - area of the smaller circle Area of the smaller circle = πr^2 3.14×4×4 = 3.14×16 = 50.24cm^2 Area of the larger circle = πR^2 3.14×6×6 = 3.14×36 = 113.04cm^2 Therefore area of the shaded region = 113.04 - 50.24 = 62.8cm^2
