A group of students were surveyed to find out if they like watching television or reading during their free time.
2 answers:
90 students like watching television
20 students like watching television but do not like reading
80 students like reading
40 students do not like watching television
Make a two-way table to represent the data and use the table to answer the following questions.
Part A: What percentage of the total students surveyed like both watching television and
Part B: What is the probability that a student who does not like watching television also does not like reading?
A) 70/130*100 = 53.8 %
B) 30/40 = 3/4 = 0.75
hope you have a great day !

I dont have paper with me but just solve 2(-2)^3+2 for the first one. The second one is -28 though
First change the 1/2 to eighths. multiply numerator and denominator by 4.now subtract 4 1/8
Do 4+3+5 which = 12
then do 48 divided by 12 which is 4
Now 4 x 4 = 16
3 x 4 = 12
5 x 4 = 20
16 + 12 + 20 = 48 so its divided as 16:12:20
3d - e = 7d + e = 5 ⇒ 3d - e = 5
7d + e = 5
3d - e = 5
7d + e = 5 +
-----------------------
10d / = 10
10d = 10
d = 10/10
d = 1
7d + e = 5
7×1 + e = 5
7 + e = 5
e = 5 - 7
e = -2
If it is repeating then it is 5/9 but if it is just 0.5 then 1/2
