After she worked out the problem, she had a discrepancy (disagreement) of
about 45% between her estimate and the quotient.
That's a lot ! There's almost definitely a major mistake somewhere, and
there really isn't any way to tell whether the mistake is in the estimate or
in the quotient.
My answer to the question is that Lilly has to go all the way back to the
beginning, and do the whole thing again. Only this time, she has a harder
job to do: She not only has to make another estimate and work out the
division problem again. This time, she also has to find the mistake that
she made the first time ... and there may be more than one of them.
Boy that math stuff will kill a cracker
Answer:
Both the mean and median will decrease, but the mean will decrease more than the median.
Step-by-step explanation:
Removing the wheel of cheese will decrease the median a little bit, because the median shifts from between two data points to the lower of the two data points:
With the wheel of cheese, the median is the middle number, but there's no middle number in this data set! So, to find the median we take the mean of the two middle numbers, $4.79 and $5.19 which is $4.99.
Without the wheel of cheese,
Removing the wheel of cheese will decrease the mean significantly, because the total cost will decrease by $39.99, and the number of items decreases by only 1.
Answer:
![Time = 11\frac{2}{3}\ min](https://tex.z-dn.net/?f=Time%20%3D%2011%5Cfrac%7B2%7D%7B3%7D%5C%20min)
Step-by-step explanation:
Given
![Security\ A = 2\ mins, 20\ secs](https://tex.z-dn.net/?f=Security%5C%20A%20%3D%202%5C%20mins%2C%2020%5C%20secs)
![Security\ B = 1\ mins, 40\ secs](https://tex.z-dn.net/?f=Security%5C%20B%20%3D%201%5C%20mins%2C%2040%5C%20secs)
Required
After how many minutes, will they round together
First, convert the given time to minutes
![Security\ A = 2\ mins, 20\ secs](https://tex.z-dn.net/?f=Security%5C%20A%20%3D%202%5C%20mins%2C%2020%5C%20secs)
![Security\ A = 2\ mins+ 20\ secs](https://tex.z-dn.net/?f=Security%5C%20A%20%3D%202%5C%20mins%2B%2020%5C%20secs)
![Security\ A = 2\ mins+ \frac{20}{60}\ min](https://tex.z-dn.net/?f=Security%5C%20A%20%3D%202%5C%20mins%2B%20%5Cfrac%7B20%7D%7B60%7D%5C%20min)
![Security\ A = 2\ mins+ \frac{1}{3}\ min](https://tex.z-dn.net/?f=Security%5C%20A%20%3D%202%5C%20mins%2B%20%5Cfrac%7B1%7D%7B3%7D%5C%20min)
![Security\ A = 2\frac{1}{3}\ min](https://tex.z-dn.net/?f=Security%5C%20A%20%3D%202%5Cfrac%7B1%7D%7B3%7D%5C%20min)
![Security\ B = 1\ mins, 40\ secs](https://tex.z-dn.net/?f=Security%5C%20B%20%3D%201%5C%20mins%2C%2040%5C%20secs)
![Security\ B = 1\ mins+ 40\ secs](https://tex.z-dn.net/?f=Security%5C%20B%20%3D%201%5C%20mins%2B%2040%5C%20secs)
![Security\ B = 1\ mins+ \frac{40}{60}\ min](https://tex.z-dn.net/?f=Security%5C%20B%20%3D%201%5C%20mins%2B%20%5Cfrac%7B40%7D%7B60%7D%5C%20min)
![Security\ B = 1\frac{2}{3}\ min](https://tex.z-dn.net/?f=Security%5C%20B%20%3D%201%5Cfrac%7B2%7D%7B3%7D%5C%20min)
So, we have:
![Security\ A = 2\frac{1}{3}\ min](https://tex.z-dn.net/?f=Security%5C%20A%20%3D%202%5Cfrac%7B1%7D%7B3%7D%5C%20min)
![Security\ B = 1\frac{2}{3}\ min](https://tex.z-dn.net/?f=Security%5C%20B%20%3D%201%5Cfrac%7B2%7D%7B3%7D%5C%20min)
List out the multiples of the time of both security personnel take round.
![Security\ A = 2\frac{1}{3}min,\ 4\frac{2}{3}min,\ 7min,\ 9\frac{1}{3}min,\ 11\frac{2}{3}min...](https://tex.z-dn.net/?f=Security%5C%20A%20%3D%202%5Cfrac%7B1%7D%7B3%7Dmin%2C%5C%204%5Cfrac%7B2%7D%7B3%7Dmin%2C%5C%207min%2C%5C%209%5Cfrac%7B1%7D%7B3%7Dmin%2C%5C%2011%5Cfrac%7B2%7D%7B3%7Dmin...)
![Security\ B = 1\frac{2}{3}min,\ 3\frac{1}{3}min,\ 5min,\ 6\frac{2}{3}min,\ 8\frac{1}{3}min,\ 10min\ ,11\frac{2}{3}min,...](https://tex.z-dn.net/?f=Security%5C%20B%20%3D%201%5Cfrac%7B2%7D%7B3%7Dmin%2C%5C%203%5Cfrac%7B1%7D%7B3%7Dmin%2C%5C%205min%2C%5C%206%5Cfrac%7B2%7D%7B3%7Dmin%2C%5C%208%5Cfrac%7B1%7D%7B3%7Dmin%2C%5C%2010min%5C%20%2C11%5Cfrac%7B2%7D%7B3%7Dmin%2C...)
In the above lists, the common time is:
![Time = 11\frac{2}{3}\ min](https://tex.z-dn.net/?f=Time%20%3D%2011%5Cfrac%7B2%7D%7B3%7D%5C%20min)
<em>This implies that they go on round after </em>

All you have to do is write your question and someone will answer. For example, instead of writing "I do not understand how I find answers on here" you would ask something like what is 9*5? Then 2 people will see your question and answer. There are no pre-recorded answers, everything happens live. Hope this helps!
