Apoll of 72 seniors, taken three weeks before the selection of the school
homecoming queen, identified 60 who planned to vote for jenny wonderful.
unfortunately, a week after the poll was taken, the school newspaper ran an
article that quoted jenny slandering her opponents. another poll of 80 seniors
taken shortly after the article appeared showed that 56 planned to vote for
jenny. does this indicate a significant drop in support for jenny? use good
statistical reasoning to support your answer.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
