Answer:
I don't know this exactly, but I'll give it my best go!
We can get the answer by answering questions we know are true and eliminating the ones we don't.
E: Experimental probability can be written in the form of a ratio.
- Any probability can be expressed by a ratio so this is true.
B: Experimental probability is the same as theoretical probability.
- They are two different 'types' of probability so this is most likely false.
A: Experimental probability has the total number of trials in the numerator and the number of times an event occurs in the denominator.
- I'm fairly certain that applies to theoretical probability, not experimental.
So that means the answers are most likely C, D, and E. If I was wrong let me know!
Answer:
Step-by-step explanation:
Multiply both denominators till they are the same than Multiply numerators by the number you multiplied by
First, find a least common number for 4 and 6. It is 12.
Then try to change the denominator of the fraction to 12.
3/4=9/12
5/6=10/12
9514 1404 393
Answer:
Step-by-step explanation:
The tangent of the angle can be found using the identity for the tangent of the difference of angles.
tan(α-β) = (tan(α) -tan(β))/(1 +tan(α)tan(β))
The tangent of the angle of each vector is the ratio of the j coefficient to the i coefficient.
tan(α) = -2/3
tan(β) = 4/7
tan(α-β) = (-2/3 -4/7)/(1 +(-2/3)(4/7))
= (-14-12)/(21 -8) = -26/13 = -2
Then the magnitude of the angle between the vectors is ...
arctan(2) ≈ 63.43°
