Answer:
a) 2.5 shots
b) 59.4 shots
c) 4.87 shots
Step-by-step explanation:
Probability of making the shot = 0.6
Probability of missing the shot = 0.4
a) The expected number of shots until the player misses is given by:
The expected number of shots until the first miss is 2.5
b) The expected number of shots made in 99 attempts is:
He is expected to make 59.4 shots
c) Let "p" be the proportion shots that the player make, the standard deviation for n = 99 shots is:
The standard deviation is 4.87 shots.
First we need to find the lengths of vector u and v. We can find this by distance formula:
and
We need to find | 3u - 2v |, which is the absolute value of 3u - 2v.
3u = 3 x 18.79 = 56.37
2v = 2 x 10.82 = 21.64
So,
| 3u - 2v | = | 56.37 - 21.64 | = | 34.73 | = 34.73
Answer:
= −3

Hope I helped you!!!
P.S. If you look up this on G oo gle, it will give ou a step by step answer.
Happy to help! :)
I think u have to multiply both side by 1x to get rid of the x so the answer is the first one, 1
