Neither one has eaten a greater amount, because 1/4 and 2/8 are equal to each other. You know this because when you divide the numerator and the denominator of 2/8 by 2, you get 1/4, which is the exact same thing. The only way the amounts would vary is if the size of one candy bar is greater than the other.
Answer:
Step-by-step explanation:
Find the midpoint of each frequency range, multiply that number by the frequency, sum up and divide by the total frequency.
This will give the mean number.
<u>The mean is:</u>
- [17*( 3 + 3.5)/2 + 21*(3.5 + k)/2 + 33*(k + 4)/2 + 54*(4 + 4.5)/2 + 15*(4.5 + 6)/2]/140 = 4.09
- 55.25 + 10.5k + 36.75 + 16.5k + 66 + 229.5 + 78.75 = 140*4.09
- 17k + 466.25 = 572.6
- 17k = 572.6 - 466.25
- 17k = 106.35
- k = 106.35/17
- k = 6.26
Note, I expected the value of k between 3.5 and 4. This is a bit of illogical outcome.
Is this multiple choice, or.... ?
Since during middle of each month, Bryce withdraws half of his amount. So at the end of each month, his balance is 1/2 times as compared to balance of his previous month.
The following recursive function represents the Brye's balance at end of each month:
where
is the account balance of previous month. And
is the account balance of current month.
