Answer:
x = 3
y = 6
Step-by-step explanation:
Apply the angle bisector theorem to find both variables.
Based on the theorem, we would have the following:
✔️x/2 = 6/4
Cross multiply
x*4 = 6*2
4x = 12
4x/4 = 12/4
x = 3
✔️9/y = 3/(8 - y)
Cross multiply
9(8 - y) = 3*y
72 - 9y = 3y
72 = 3y + 9y
72 = 12y
72/12 = 12y/12
6 = y
y = 6
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)
8) y intercept is (0, 15) or 15
slope is 10 (the y intercept represents how much it would cost to open an online gaming account and the slope represents how much each game costs after you open an online gaming account, including the $15 fee to open the account)
9) y=10x+15
10) you can look at the graph where it says number of games and go to 6 and go up until you reach the line and look at the side where it says cost (dollars) and then you will see that 6 games cost $75
