(a)complete the two-way from the data. of the men surveyed, how many were 30 and younger? how many men did not have facial hair? use the chart above to complete this problem.

(b)complete the two-way frequency table using table a. round to the nearest hundredth. use the chart above to complete this problem.

(c)what percentage ofmen older than 30 had facial hair?

a) 7 were 30 or younger

4 of ≤ 30 and 3 of ≥ 30 has no facial hair

b) as attached

c) c) 5/15= 1/3 ( 33.33%) of men older than 30 has facial hair, in total group

   0r 5/8 = 0.625 (62.5%) of men older than 30 in his age group has facial hair

Step-by-step explanation:

a) b) shown in attached

c) 5/15= 1/3 ( 33.33%) of men older than 30 has facial hair, in total group

   0r 5/8 = 0.625 (62.5%) of men older than 30 in his age group has facial hair

the answer on e2020 is

10

4/5

3/5

4/3

step-by-step explanation:

the correct answer option is (2x-3)(2x+3).

step-by-step explanation:

we are given the following expression and we are to factorize it:

we are to find such factors that when multiplied they give a result of 36 (9 x 4 = 36) and when added they give a result of 0.

the two such factors of 36 are negative six and postive six.

factorizing the given expression to get:

therefore, the correct factorization of is (2x-3)(2x+3).
