How many different answers can you get by grouping differently? add parentheses to the expression 7+3•4+2 to create new expressions with as many different values as possible.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)

When 142 is added to a number the result is 64 more times the number my options are 35 37 39 41
