Students in a class were surveyed about the number of children in their families. The results of the survey are shown in the table. A 2-column table has 5 rows. The first column is labeled Number of children in family with entries 1, 2, 3, 4, 5 or more. The second column is labeled Number of surveys with entries 9, 18, 22, 8, 3.

Two surveys are chosen at random from the group of surveys. After the first survey is chosen, it is returned to the stack and can be chosen a second time. What is the probability that the first survey chosen indicates four children in the family and the second survey indicates one child in the family?

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0

you have to put the graph on here with the question
