The science of physics, specifically projectile motion, goes hand in hand with the mathematics of trigonometry. We need the math
Luda [366]
If we want to calculate the time it takes to fill a water tank, we need the flow and volume of the tank.
 The flow must be a data, but for the volume of the tank we need mathematics.
 For example, if it is a cylinder, we need mathematics to know that the volume of the cylinder is:
 V = pi * r ^ 2 * h

2. What is the external probability of rolling a 4
Nataly_w [17]

Answer:

2. 1- Experimental probability of rolling a 4 = 40%

3. 2- Theoretical probability is 3%  greater than experimental probability.

Step-by-step explanation:

Experimental probability of rolling a 4 = 100 × \frac{8}{20}

                                                                  = 100 × 0.4

                                                                  = 40%

Experimental probability of getting at least one tail  = \frac{72}{100}

                                                                                    = 0.72

Theoretical probability of getting at least one tail  = \frac{3}{4}

                                                                                  = 0.75

Theoretical probability is 3%  greater than experimental probability.
