If the weight of the bottom box is b then the weight of a stack of four boxes is b + b/2 + b/4 + b/8
= 8b/8 + 4b/8 + 2b/8 + 1b/8
= 15/8 b
A stack must weigh less than 100 pounds
15/8 b < 100
b < 100 x 8/15 = 53 1/3 pounds
If boxes have a minimum weight of 1 pound then
for stacks that contain 4 boxes the range of b is [8, 53 1/3)
and if stacks contain 1 to 4 boxes the range of b is [1, 53 1/3)
If the only restriction is a maximum of 100 then the range of b is [0, 53 1/3)
Answer:
p = 0.68 and p^ = 0.6
Step-by-step explanation:
Jackie received 68% of the votes in an election.
Here p is the decimal equivalent of 68 %.Hence ,
p = 0.68
Now we have taken a sample of 30 people from the total number of voters and we have to find the percentage of votes that Jackie gets in this .
Out of 30 people Jackie got 18 votes. Hence,
p^ = = 0.6
Hence the values are
p = 0.68 and p^ = 0.6
In the random sample we have taken the probability of Jackie has decreased but it will be compensated by another sample where it will be more.
