Need help with a math question

Mathematics
1 answer:

<u>Answer:</u>

57%

<u>Step-by-step explanation:</u>

We are given the results of survey of one thousand families to determine the distribution of families by their size.

We are to find the probability (to the near percent) that a given family has 3, 4 or 5 people.

Frequency of families with 3, 4 or 5 people = 200 + 245 + 125 = 570

Total frequency = 1000

P (families with 3, 4 or 5 people) = (570 / 1000) × 100 = 57%

Why is 20 to 40 a 100% increase
Oksi-84 [34.3K]

increasing 20 to 40 is the same as increasing 20 by 20 (or itself), so it is a 100% increase. Decreasing 40 to 20 is the same as decreasing 40 by 1/2 or by 20. So it is a 50% increase.

when going from 20 to 40, the number is being doubled, and when youre going from 40 to 20 you are cutting the number in half. 

hope this helped:)

Write the fraction that would land on point A on the number line.
Mashutka [201]
1/3

There are six lines. 1/6, 2/6, 3/6, 4/6, 5/6, and 6/6. 6/6 is 1, the last line.

Point A is at 2/6. Since both numbers can be reduced by 2, you divide them both by 2. The final answer would be 1/3.
