Answer:
Theoretical probabilities are the long-run relative frequencies based on an experiment.
Step-by-step explanation:
Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.
With theoretical probability, you don't experiment. Instead, you use what you know about the situation to determine the probability of an event occurring.
Experimental probability approaches theoretical probability when the number of trials is extremely large.
Therefore, theoretical probabilities are the long-run relative frequencies based on an experiment.

Answer: D) 72</h3>
======================================
Work Shown:
Angle PQR = (far arc - near arc)/2
2x+72 = ( (2x+252) - (2x+108) )/2
2x+72 = 144/2
2x+72 = 72
2x = 72-72
2x = 0
x = 0/2
x = 0
-------------
Angle PQR = 2x+72
Angle PQR = 2(0)+72
Angle PQR = 72 degrees
Well, since we do not know the line, the basic slope formula is Y = mX + B
So look at the line and see where is crosses the y axis (the vertical) and that is your B in the formula or the "Y-intercept" as an example I will used the number 1. Then on your line pick two points, I will use the points (4,4) and (1,2) as an example. To find your slope take the Ys in those points (the second number) and subtract them 4 - 2 = 2. Then subtract the Xs (the first numbers) 4 - 1 = 3. Lastly, take the 2 and divide it by the 3 (yes it can be a fraction) and that is your slope. So the entire answer with my examples would be Y =

x + 1 with 1 being my y-intercept and 2/3 being my slope
Answer:
It will cost $512.73
Step-by-step explanation:
9 in by 6 in sandbox cost $228
i.e., 9*6 = 54 in²
54 in² cost $228
1 in² will cost $228/54
≈ $4.22
If the new dimension is 13 1/2 in by 9 in
then area will be 13 1/2*9
27*9/2 = 121.5 in²
The cost of 121.5 in² will be
121.5*4.22 = $512.73
Answer:
51/40
Step-by-step explanation:
Find a common denominator. That would be 40. Multiply numberator and denominator by the same number to get a denominator of 40. Then you can add.
7(5)/8(5) + 2(8)/5(8)
35/40+ 16/40
51/40
