Answer:

1.09 moles.

Step-by-step explanation:

There is 70g of water in 140ml of solution.

This means there are 17.5g of water in 35ml of solution. (Divide by 4)

In 17.5g of water, there are 17.5/16 = 1.09 moles of water.

Write a equation that is parallel to 5x-y=4
ozzi
Let's have this equation equal y first. All we have to do is add y to both sides and subtract 4 from both sides.
5x-4=y
Now, to get a parallel line, the y intercept has to change. The y intercept (the -4 in the equation) can be an infinite amount of number but -4.
Let's choose 6. We would have 5x+6=y or you could put it in the way the other equation was, 5x-y=-6.

Which of the following represents a negative correlation?
babunello [35]

Answer:

The answer is letter B, The water level in a bathtub as it drains over time.

Step-by-step explanation:

It is best to learn the meaning of <u>"negative correlation"</u> first.

Correlation- In Mathematics, "correlation" means a measure of the relationship between two variables.

<em>Positive Correlation-  </em>when the values of the variables increase together.

<em>Negative Correlation- </em>when one value of a variable increases while the other variable's value decreases.

*The situation above is asking for a negative correlation, therefore the answer is letter B (The water level in a bathtub as it drains over time).

The variables are: <u>water level and draining time</u>

As the draining time increases, the water level in the bathtub decreases. This is clearly an example of a negative correlation.
