Answer:

x = 3

y = 9

Step-by-step explanation:

$\frac{x}{y} =\frac{1}{3}$ → ( 1 )

Use cross multiplication to the above equation.

3x = y → ( 2 )

x + y = 12 → ( 3 )

Now you can put 3x instead of y to equation (3) according to equation (2).

Let us solve.

x + y = 12

x + 3x = 12

And now you can solve the above equation and find the value of x.

4x = 12

Divide both sides by 4.

x = 3

Now we can put 3 instead of x to any equation here and find the value of y.

Let us take equation ( 2 )

3x = y

3 × 3 = y

9 = y

Hope this helps you :-)

Let me know if you have any other questions :-)

Identify whether each question is a statistical question and the reason why or why not.

madam [21]

1. The question about the weight of the football team players is statistical because it requires data collection to answer it and the data is variable.

2. The question about the height of Ben's mother is non-statistical because it does not require data collection to answer and the data is not variable, since it is one data point.

<h3>What is a statistical question?</h3>

A statistical question can be answered by collecting data and for which data will vary.

Questions answered with a single data point are not statistical because there is no data variability to answer them.

A statistical question can be determined by the following criteria:

Provides useful data about a group of people.
Many people can answer it.
There will be many different answers.
The data collected explains a situation or reality.

Thus, the question about the weight of the players asks a statistical question, unlike the height of Ben's mother.

If line a is perpendicular to line b and the slope of line a is 7 whats the slope of line b

amm1812

Answer:

If a line is perpendicular to another line, that means that the slope is completely opposite that of the original line. The first thing that we do to the slope is we negate the number which means that if we have a slope of $-7$ our slope because $7$ in this step. In our case our slope is $7$ so in this step it becomes $-7$ .

Moving onto the second part which is to get the reciprocal of the number which means that if we have $\frac{1}{2}$ then we would switch it to $2$ . In our case our number is $-7$ so we would make that into a fraction like this $-\frac{1}{7}$ .
