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:
81/16 = 5 1/16
Step-by-step explanation:
-4(square root of x) -3 = -12
Add 3 to both sides
-4(square root of x) = -12 +3 = -9
Divide both sides by -4
(square root of x) = -9/-4
-/- equals +
(square root of x) = 9/4
Square both sides to cancel the square root
x = (9/4)^2 = 81/16 = 5 1/16

Answer:
D. 0.77
Step-by-step explanation:
Jonas builds a snow fort. He tells his friends it is 0.8 meters tall inside, but he rounded the height to the nearest tenth. Which could be the height of the snow fort before Jonas rounded it?
Check all options by rounding to the nearest tenth
A. 0.89 m
= 0.9 m
B. 0.74 m
= 0.7 m
C. 0.85
= 0.9 m
D. 0.77
= 0.8 m
Note: Digits 0 - 4 are rounded down while digits 5 - 9 are rounded up
Rounding to the nearest tenth means having one digits after the decimal point
