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>
Answer:
4
Step-by-step explanation:
To answer this question, you can use the values of the unit circle to figure out the angle measurement. Since the cosine is the x value of the circle, we can see that at 45°<span>, the x value is √2/2.
So the missing angle should be 45°</span>
Answer:
x = 1.89
Step-by-step explanation:
Solve 22 - 10.2 + 25 to get 36.8 as the square's area.
Set up the equation 36.8 = (-10x + 25)^2 to represent the relationship between one side length and the area.
Reverse the equation to solve for x! Find the square root of both sides to cancel out the exponent. This gets you: 6.07 = -10x + 25.
Subtract 25 from both sides, then divide by -10 to get x by itself.
x = 1.89
Answer:
16 ride tickets.
Step-by-step explanation:
The original entry fee is $4 so you can subtract that from 12. Now you have $8. So you would double 8 since $0.50 is half of $1. 8x2 is 16.
