if 1 divided by 3x is equal to 4 divided by 7y, which of the following expresses x in terms of y?

Answers

Answer 1

x = (7y/4) / (3/1) = 7y/3

If 1 divided by 3x is equal to 4 divided by 7y, then we can cross-multiply and set the two expressions equal to each other:

1 = 4(3x) / 7y

To solve for x in terms of y, we can then multiply both sides of the equation by 7y and divide by 4:

7y = 4(3x)

y = 3x / 4

Therefore, x is expressed in terms of y as 3x/4. This is because we have used the property of equation, which is cross multiplying and dividing by a common factor to get the variable we want to express in terms of the other variable.

Answer 2

Answer:

x=7y/12

Explanation:

Given:

1/3x=4/7y

According to the proportion property:

3x*4=7y*1

12x=7y

x=7y/12

Explanation:

The outcome 0, 1, 1 has a sample mean of x-bar = (0+1+1)/3 = 2/3 = 0.667

For independent outcomes, the probability of an outcome is the product of the probabilities of each individual event, which in this case would be the probability of getting a 0, the probability of getting a 1, and the probability of getting another 1.

If we assume that the probability of getting a 0, a 1, or a 1 is the same (let's say p) the probability of getting the outcome 0, 1, 1 would be ppp = p^3

So the answer is A. x-bar = 0.667, p = p^3

Note that the question doesn't provide the probability of getting a 0, 1, or 1, so I assumed the probability is the same.
