The experimental probability, sometimes known as the relative frequency, is the number of times the 'interesting' event occurs divided by the number of events in total that have occurred.
In your case, the 'interesting' event is rolling a 3. This happened <u>11 times</u>.
The total number of events that have occurred is 7+9+11+6+9+8 = <u>50</u>.
So the experimental probability of rolling a three is 11/50 = <u><em>0.22</em></u>
It should be 40 percent.
You can think of it as starting with 100 as in 100 dollars or 100 tic tacs
If you take away 25%, you take away 25 tic tacs and now you only have 75.
From your 75, you take away 20% which is equal to 15. 75- 15=60
If you look at the end result of 60, you can see that that is 100 - 40 so 40% of the total was taken off
Answer:
Each bike with both types of tire.
Half of the tires of each type will be in the front wheel and the other half in the rear wheel.
Step-by-step explanation:
To compare the wear of each type of tire in a matched-pair test, the individuals have to test each of the tires in the same conditions.
This will allow to compare the tires wear in equal conditions. If the tires are assigned randomly to the volunteers, there will be difference in the wear due to difference habits of the bikers.
The only way to implement a matched-pair test with bikes is to use one type of tire in the front wheel and the other type in the rear wheel. Half of the tires of each type will be in the front and half in the rear.
In this way, the distance traveled with each type of tire will be the same.
Answer: They can recieve about 2.
Exact answer: 2.5
Step-by-step explanation:
If you divded 100 by 40, you get 2.5
Since there are 20 students in each AM and PM classes. you add 20 and 20, which is 40, then you divided by 100 which is 2.5
