Answer:
Option C
Step-by-step explanation:
We want to know the percentage of women among people who only prefer exercise.
We have the following information:
Diet Only Exercise Only Diet and Exercise
Men 7 28 15
Women 22 18 10
Then we get the total of people who prefer just exercise.
Now the proportion of women who only prefer exercise is calculated as:
Therefore we must search among the options the table that shows a proportion of 39 for women who prefer only the exercise.
This table is in option C.
C.
Diet Only Exercise Only Diet and Exercise
Men 0.24 0.61 0.60
Women 0.76 0.39 0.40
Sure. From those choices, the only one that makes sense is that he
didn't perform enough trials. Technically, you can't expect the experimental
probability to match the theoretical probability until you've rolled it an infinite
number of times.
I have a hunch that even for only 60 trials, such a great discrepancy between
theory and experiment is beginning to suggest that the cubie is loaded. But
you really can't say. You just have to keep trying and watch how the numbers
add up.
Answer:
89 km/hr
Step-by-step explanation:
Distance = Rate(speed) × Time
D = R × T
T = 4 hours
One car's rate is 12 kilometers per hour less than the other's.
Hence:
First's car's rate = r × 4 = 4r
Second car's distance = (r + 12) × 4 = 4r + 48
4r + 4r + 48 = 760
8r + 48 = 760
8r = 760 - 48
8r = 712
r = 712/8
r = 89 km/hr
The rate of the slower car is 89 km/hr
Answer:
Step-by-step explanation:
The answer is 48 feet because 4x6=24 and 24x2=48
