Find the 4th term in the sequence with the following definition:
A1= 0
An=2 (an-1 -3)

A2=2(a2-1-3)

A2=2(a1-3)

A2=2(0-3)

A2=-6

A3=2(a2-3)

A3=2(-6-3)

A3=2*-9

A3=-18

A4=2(a3-3)

A4=2(-18-3)

A4=-42

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

$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)
