Answer: -15y
Step-by-step explanation:
6(x-2y) - 3(2x+y)
6x-12y -6x-3y
0x -15y
-15y
Answer:
it is 512
Step-by-step explanation:
Answer: 3/2
Step-by-step explanation:
Since, two variables are called proportional if there is always a constant ratio between them.
And, The constant is called the coefficient of proportionality or proportionality constant.
Let x and y are proportional to each other.
Therefore, x ∝ y ⇒ y=kx
Where k is any constant.
For, x=2 and y=3 k= 3/2
For, x=4 and y=6, k=3/2
For x=6 and y=9, k= 3/2
Since, here the value of k is constant.
Therefore, k is the coefficient of proportionality.
And, given table is propositional.
Answer:
85.56% probability that less than 6 of them have a high school diploma
Step-by-step explanation:
For each adult, there are only two possible outcomes. Either they have a high school diploma, or they do not. The probability of an adult having a high school diploma is independent of other adults. So we use the binomial probability distribution to solve this question.
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.
50% of adult workers have a high school diploma.
This means that
If a random sample of 8 adult workers is selected, what is the probability that less than 6 of them have a high school diploma
This is P(X < 6) when n = 8.
In which
85.56% probability that less than 6 of them have a high school diploma
