Answer:

The graph should look almost exactly like this. I used a virtual graphing chart to assist, since it is capable of showing more than paper alone.

Which set of four test scores would have the biggest difference between the mean and the median? A. 32, 85, 89, 91, 92, 92 B. 72

postnew [5]

Answer:

A. 32, 85, 89, 91, 92, 92

Step-by-step explanation:

A. 32, 85, 89, 91, 92, 92

Mean

$\bar{x}=\dfrac{32+85+89+91+92+92}{6}\\\Rightarrow \bar{x}=80.167$

Since the number of scores is 6 which is an even number the median will be of the form $\dfrac{x_{n/2}+x_{(n/2)+1}}{2}$

Median

$\dfrac{89+91}{2}=90$

Difference of mean and median = $|80.167-90|=9.83$

B. 72, 78, 79, 80, 82, 82

Mean

$\bar{x}=\dfrac{72+78+79+80+82+82}{6}\\\Rightarrow \bar{x}=78.83$

Median

$\dfrac{79+80}{2}=79.5$

Difference of mean and median = $|78.83-79.5|=0.67$

C. 65, 70, 75, 80, 85, 90

Mean

$\bar{x}=\dfrac{65+70+75+80+85+90}{6}\\\Rightarrow \bar{x}=77.5$

Median

$\dfrac{75+80}{2}=77.5$

Difference of mean and median = $|77.5-77.5|=0$

D. 30, 34, 39, 41, 48, 50

$\bar{x}=\dfrac{30+34+39+41+48+50}{6}\\\Rightarrow \bar{x}=40.33$

Median

$\dfrac{39+41}{2}=40$

Difference of mean and median = $|40.33-40|=0.33$

So, A has the maximum difference of 9.83 between the mean and the median.

It's a little hard to tell without more information as to what you are learning, but could it be the Golden Ratio? I believe it might have been discovered in ancient Greece...

Lilly starts hiking along a trail at 3 miles per hour. Dave starts hiking the same trail from the same starting point at 3.5 mil

DerKrebs [107]

Given:

Lilly starts hiking along a trail at 3 miles per hour.

Dave starts hiking the same trail from the same starting point at 3.5 miles per hour.

lilly walked 2 miles before Dave started hiking.

To find:

Whether he will catch up to her and write an equation.

Step-by-step explanation:

Let the number of hours when both are hiking be h.

lilly walked 2 miles before Dave started hiking at 3 miles per hour.

Lilly hiking = 2+3h

Dave starts hiking the same trail from the same starting point at 3.5 miles per hour.

Dave hiking = 3.5 h

He will catch her if hiking distance of both are equal.

$2+3h=3.5h$

Subtract 3h from both sides.

$2=3.5h-3h$

$2=0.5h$

Divide both sides by 0.5.

$\dfrac{2}{0.5}=h$

$4=h$

Therefore, Dave will catch her after 4 hours.
