Jackie is practicing free throws after basketball practice. She makes a free throw shot with probability 0.7. She takes 20 shots
Sergeu [11.5K]

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.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

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 p = 0.7 and q = 1-p = 0.3

She takes 20 shots.

This means that n = 20

So the correct answer is:

n = 20 q = 0.7, q = 0.3

Which line segment is not a diameter or radius of circle F?
spin [16.1K]
Short Answer: AB
Argument
Take F to be the center. The line segment that IS a diameter or radius must either go through F (that would make the line a diameter) or to be a radius the segment mus end in F and touch the circumference once.   See below.

The diameter must not only go through F, it must touch the circumference in two places. EFB is a diameter. So is AFC

The radius must have 1 endpoint at the center and one endpoint on the circumference. DF is a radius.


So what isn't?  Answer: AB isn't. It neither goes through F nor is F one of the end points.

Answer: AB
