Ans is (b, a)
although we dont kn the values of a and b,
the x coordinate of c must be same as point D,and y coordinate of C must be same as point B.U can draw a graph to help urself understand better
Area of semicircle: pi * r^2/2
r = 9/2 = 4.5
3.14 * 4.5^2 = 63.585/2 = 31.7925
Area of middle section:
Make it a rectangle: L * W
9 * 12 = 108
Area of bottom: L * W
6 * 9 = 54
Now add together: 31.7925 + 108 + 54 = 193.7925, round to nearest hundred
Solution: 193.79 in^2
Probability is defined as the number of desired outcomes over all possible outcomes. Lets say each second is one possible outcome. This means there is 30 different desired outcomes out of 60 possible outcomes. The probability therefore is 30/60, simplified to 1/2.
Answer:
D. Class frequency divided by the total frequency.
75% of 36= 27
7.5%= 2.7
36+2.7=£38.70
