If those two are your only choices then the answer is none of the above.

<em>Attached is a cumulative frequency table for your data.</em>

If you take a look at the two tables given, the frequencies were not tallied properly. If the frequency column is wrong, then the cumulative frequency will be wrong.

The answer is then none of the above or find one that matches the table attached.

Question 6

Aleksandr-060686 [28]

Answer:

33 children

62 adults

Step-by-step explanation:

Set up 2 equations (a=adults c=children)

The first equation will be 3.25(a)+3 = 300.5

The second equation will be a + c = 95

Subtract c from both sides to get:

a = 95 - c

Replace c in the 1st equation to get:

3.25(95-c) + 3c = 300.5

Distribute 3.25 to 95 and -c:

308.75 - 3.25c + 3c = 300.5

Subtract 308.75 from both sides:

-3.25c + 3c = 300.5 - 308.75

Combine like terms:

-0.25c = -8.25

Divide by -0.25

children = 33

Subtract 33 from 95 to get

adults = 62
