How many of each animal do you have
<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%
Answer:1/4 and 3/4
Step-by-step explanation:
There are 4 squares, one of which is shaded i.e1 out of four is shaded which is written as 1/4.
Also 3 out of 4 is not shaded which is written as 3/4
Notice, ending ends makes it easeier
1+20=21
2+19=21
...
10+11=21
there are 10 pairs of numbers
they add to 21
10 times 21=210
the sum is 210
