Answer:
I don't think there is a way the values can be determined...
Let us assume the first even number = n
The second consecutive even number = n + 2
The third consecutive even number = n + 4
The addition of the three consecutive even numbers is 42 and it is already given in the question. Based on the information's given in the question, the answer can be easily deduced.
Then, the equation can be written as
n + (n + 2) + (n + 4) = 42
3n + 6 = 42
3n = 42 - 6
3n = 36
n = 36/3
= 12
So
The first even number = 12
The second consecutive even number = n + 2
= 12 + 2
= 14
The third consecutive even number = n + 4
= 12 + 4
= 16
So the three consecutive even numbers are 12, 14, 16.
Answer:
A binomial probability density function should be used because the question asks for determining the probability that exactly 10 students wear glasses.
Step-by-step explanation:
A binomial probability density function is used when we want to know the probability of an exact value.
A cumulative distribution function is used when we want to know the probability of less than or equal to a value.
