Answer:
The vector is .
Step-by-step explanation:
We can determine the equivalent vector (), dimensionless, by means of the following formula:
(1)
Where:
- Original vector, dimensionless.
- Norm of the original vector, dimensionless.
- Norm of the new vector, dimensionless.
The norm of the original vector is determined by the following definition:
(2)
If we know that , then the norm of the original vector is:
If we know that , then the new vector is:
The vector is .
Answer:
n = 20 q = 0.7, q = 0.3
Step-by-step explanation:
For each shot that she takes, there are only two possible outcomes. Either she makes or, she does not make is. The probability of making each shot is independent from other shots. So we use the binomial probability distribution to solve this problem.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
We also ahve that q = 1-p.
Jackie is practicing free throws after basketball practice. She makes a free throw shot with probability 0.7.
This means that and
She takes 20 shots.
This means that
So the correct answer is:
n = 20 q = 0.7, q = 0.3
