Answer:
After t = 4 the rocket will hit the ground.
Step-by-step explanation:
We are given a parametric equation as x = 3t² and y = - 4t + 16.
If we assume that the x is a measure of horizontal distance, y is the measure of vertical distance and t is the time of travel of the rocket, then by making y = 0, we will get the time to hit the ground.
Hence, - 4t + 16 = 0
⇒ t = 4
Therefore, after t = 4 the rocket will hit the ground. (Answer)
Answer:
a)
A=30,32,44,48
B=22,34
intersect=26
numbers going outside is 24,28,36,38,40,42,46
b) 1/14
Step-by-step explanation:
a)The numbers that will go into the A bracket will be 30,32,44 and 48. The numbers that will go into the B bracket will be 22 and 34. The number that will go into the intersect will only be 26. And finally the numbers going on the outside of the venn diagram will be 24,28,36,38,40,42,46.
b)The answer will be 1/14
Answer:
70
Step-by-step explanation:
Experimental probability is if an experiment was actually run. If those values are the result of an experiment, then the probability is desired value (white) over total possibilities.
![\frac{12}{20} = \frac{3}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%7D%7B20%7D%20%3D%20%20%5Cfrac%7B3%7D%7B5%7D%20%20)
