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
Answer: (a) mean = 32.00
(b)Standard error = 0.068
It is expected that the shape will approximately large because n is large.
(c)P(z< 0.60)= 0
Step-by-step explanation:
a. Mean = nP= 0.64× 50 = 32.00(2dp)
P= 0.64
b. Standard error = √ p(1-p)/n
= √0.64(0.36)/50
= 0.068(3dp)
c. Using P(Z<X - U/S)
Where S = standard error
U = mean = 0.64
(c)P(z< 0.60)=
= P( z< 0.60 - 0.64/0.068)
= P( z < -5.88)
= 0.
{ 9 } ∉ S. Answer C is not correct.
If subset A represent spinning a number less than 4, its sample space is
A ={ 1, 2 , 3 }. Therefore D is also false.
Answer:
True statements are;
A ) S = { 1, 2, 3, 4, 5, 6, 7, 8 }.
B ) If A is a subset if S, A could be { 1, 2, 3 }.
E ) If a subset A represents the complement of spinning an odd number, its sample space is A = { 2, 4, 6, 8 }.
Answer:
Number of songs=360
p(classical songs)=4/9
best prediction=360*4/9=160
so they answer is 160.
