Let the angles be x and 90-x(since we are given that the angles are complementary so their sum will be 90)
now acc to question
x-(90-x)= 14
2x= 104
x= 52
and the other angle will be 90-x= 90-52 = 38
You already have one of the two answer(s) selected... (C). The other answer is E, because (27/9) = 3, then you add x. As letter C, the answer is 3x.
Total number of people in the sample = 193 + 127 + 96 = 416
Probability of picking 23-30 year old = 92 /416 = 0.2212 ( not including the people who smoke)
Number of people who smoke = 60+35+23 = 118 people
Prob(someone who smokes) = 118/416 = 0.2837
So required probability = 0.2837 + 0.2212 = 0.505 (answer)
Answer:
C is true.
Step-by-step explanation:
If you look at the model, the middle line in the box means the median and it is 7 so yeah! Hope this helped! Good Luck! :)
