Mathematics
1 answer:
Lunna [17]3 years ago
6 0

Answer:

B. Graph B

Step-by-step explanation:

The closer the data points are along the line of best fit, the closer the the correlation coefficient is to -1 or 1.

The data points in graph B are closer to each other along the line of best fits and the increase in variable x leads to a decrease in variable y, which signifies negative linear relationship.

Therefore, the correlation coefficient of graph B will most likely be close to -1.

You and your friend mix water and cirtic acid. You add 3 cups of citrtic acid for every 16 cups of water Your friend adds 2 cups
Vlad [161]

Answer:

A's mixture is more acidic.

Step-by-step explanation:

Given:

Two friends mix water and citric acid.

One (Let A) add 3 cups of citric acid for every 16 cups of water and another (Let B)adds 2 cups of citric acid for every 12 cups of water.

Now, we have to find that whose mixture is more acidic means:-

Solution:

A add 3 cups of citric acid for every 16 cups of water, the ratio = \frac{3}{16}

B adds 2 cups of citric acid for every 12 cups of water = \frac{2}{12}

Now, to find that who mix more citric acid in the mixture, firstly we will equalize the denominator of both fraction by taking LCM so that can be compare easily.

LCM of 16 and 12:- <u>48</u>

16 - 16, 32, <u>48</u>, 64, 80, 96....

12 - 12, 24, 36, <u>48, </u>60, 72.......

For friend A - \frac{3\times3}{16\times3} =\frac{9}{48}

For friend B - \frac{2\times4}{12\times4} =\frac{8}{48}

<em>We found that in terms of 48 cups of water, friend A mixes 9 cups of acid while friend B mixes 8 cups of acid, means A is adding more acid than B and</em> hence friend A's mixture is more acidic.

The figure below is a square. Find the length of side x in simplest radical form with a
Leokris [45]

Answer:

\frac{\sqrt{2} }{2}

Step-by-step explanation:

45 - 45 - 90 Triangles

When one leg = x, the hypotenuse = x\sqrt{2}

So, if the hypotenuse is 1, then divide by \sqrt{2} to get the leg.

\frac{1}{\sqrt{2} }  rationalize denominator.

\frac{1}{\sqrt{2}} × \frac{\sqrt{2}}{\sqrt{2} } = \frac{\sqrt{2}}{\sqrt{2} \sqrt{2} }  =  \frac{\sqrt{2} }{\sqrt{4}} =  \frac{\sqrt{2}}{2}
