Answer:
2z + 5
Step-by-step explanation:
you have to combine like terms
subtract 4z - 2z and you get 2z
the number with the variable next to it goes first not the constant
2z + 5
the variable is z and the constant is 5 because it doesn't have variable next to it
hope this makes sense and helps :)
tell me if you have any questions
Any number is divisible by 4, if the last 2 digits are divisible by 4,
Any number is divisible by 8, if the last 3 digits are divisible by 8, unless the last 2 digits are a multiple of 8
Answer:
There is a 25.92% probability that exactly 4 of the selected adults believe in reincarnation.
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they believe in reincarnation, or they do not believe. This means that we can solve this problem using the binomial probability distribution.
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 combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem
There are 5 adults, so
60% believe in reincarnation, so
What is the probability that exactly 4 of the selected adults believe in reincarnation?
This is P(X = 4).
There is a 25.92% probability that exactly 4 of the selected adults believe in reincarnation.
Answer:
Since x=4 is parallel to y axis it has no y intercept.
