Answer:
9
Step-by-step explanation:
E(X) = np
E(X) = (15) (0.6)
E(X) = 9
The mean of the X is 9.
What is the mean of the binomial distribution?The mean of a binomial distribution is the expected value (long-run average) of the number of successes in the given number of trials.
Formula for calculating mean of binomial distribution[tex]\mu_{x} = n.p[/tex]
where,
[tex]\mu_{x}[/tex] is the mean of the binomial distribution
n is the number of trials
and, p is the probability of success
According to the given question.
We have
Number of trials, n = 15
Probability of success, p = 0.6
Therefore, the mean of X is given by
[tex]E(X) = 15(0.6)[/tex]
⇒ [tex]E(X) = 9[/tex]
Hence, the mean of the X is 9.

When considering different sampling methods, cluster sampling includes the steps: _______.
a. use simple random sampling to select a set of groups; every individual in the chosen groups is included in the sample
b. list the members of the population; use simple random sampling to select a starting point in the population; let k = (number of individuals in the population)/(number of individuals needed in the sample); choose every kth individual in the list
c. starting with the one that was randomly selected
d. divide the population into groups; use simple random sampling to identify a proportionate number of individuals from each group
e. identify individuals of the population that are easily accessible; obtain data from these individuals
Answer:
d. divide the population into groups; use simple random sampling to identify a proportionate number of individuals from each group
Step-by-step explanation:
Remember, a cluster represents a selection out of a group belonging to a larger population. Thus, cluster sampling includes the steps;
divide the population into groups;use simple random sampling to identify a proportionate number of individuals from each group.For example, A bus company wants to survey all its customers for a particular day, using cluster sampling, they will randomly select 10 trips that day and survey some or all the passengers on those trips.

Need help please
Answer:
62
Step-by-step explanation:
Plug in the value of a in the equation:
12(4) - 6 + 7(4) - 2(4)
Solve 12(4) - 6:
12(4) - 6 = 48 - 6 = 42
Solve 7(4) - 2(4):
7(4) - 2(4) = 28 - 8 = 20
Combine both answers (42+20):
42+20 = 62
Complete answer:
12(4) - 6 + 7(4) - 2(4) = 62

In which table does y vary directly with x
Answer:
No. C
Step-by-step explanation:
please mark me brainleast
Table C shows the proportional relationship between x and y that y varies directly with x option (C) is correct.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
We have:
y vary directly with x
y ∝ x
y = kx
k is the constant.
k = y/x
Checking table A:
k = -2/1 = -4/2 ≠ -16/3
Checking table B:
k = -5/1 ≠ 18/2 = 41/3
Checking table C:
k = 26/1 = 52/2 = 78/3 = 26
Thus, table C shows the proportional relationship between x and y that y varies directly with x option (C) is correct.
