There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.
Answer:
a. range: 4
b. 5 students
c. mean: 8
Step-by-step explanation:
range: subtract the smallest number from the largest number in the data.
10 - 6 = 4
students amount was counted by the number of marks given.
mean: add the data together. (40) divide the sum by the number of marks provided. (5)
40 divided by 5 equals 8
60 degrees cause triangles equal 180° and 90+30=120 and 180-120=60°
