Answer:

120 people [see below]

Step-by-step explanation:

48 out of 120 people like baseball.

That is about 48/120 = 0.4 [40%]

Now, 3/5th of THOSE, play baseball, so

0.4 * 3/5 = 0.4 * 0.6 = 0.24 [24%].

Thus, we have seen that around 24% of total people taken would play baseball.

Now, we take 500 people, so 24% of them would be expected to play baseball.

That is 0.24 * 500 = 120 people

Madison rode her bicycle 4.5 miles in 0.75 hour. At the rate, how long would it take her to ride her bicycle an additional 6 mil

scZoUnD [109]

Set up equal ratios

t/6=0.75/4.5 multiply both sides by 6

t=4.5/4.5

t=1 hour

So it will take Madison one hour to ride another six miles.

Answer:

Step-by-step explanation:

$\overline x =\dfrac{-3\cdot4+(-2)\cdot2+3\cdot1+4\cdot1+6\cdot4+8\cdot7}{4+2+1+1+4+7}\\\\\\\overline x =\dfrac{-12-4+3+4+24+56}{19}\\\\\\\overline x =\dfrac{71}{19}=3.7368421....\approx3.74$

We start by ordering the values.

5, 7, 8, 10, 13, 14, 17, 17, 21

Now we find the median(middle number).

Median(b): 13
(I added (b) for "base" since we need to take more medians)
The median now divides this data into two halves.

Now we take the medians of the two remaining halves.

Median(Half1): 7.5
Median(Half2): 17

Mark off the minimum and maximum.

Min: 5
Max: 21

Now graph!

Your median(Half1) is incorrect, since your median for the first half is 9. Since our median for the first half is 7.5, the answer would be Answer Choice C.
