tiny-mole [99]

A method which would quickly reveal if the solution was saturated or unsaturated is to add heat to the solution and stir.

<h3>What is solubility?</h3>

Solubility can be defined as a terminology that describes how readily a chemical substance (compound) can be dissolved in a solvent to form a solution, which may either be saturated or unsaturated.

In Chemistry, a chemical substance (compound) is considered to be soluble if it dissolves completely in a solvent such as water.

In this experiment, a method which can be used by the student to quickly reveal if the solution was saturated or unsaturated is to add heat to the solution and stir because it will increase the rate in which it dissolves and settles at the bottom.

In quadrilateral $ABCD$, we have $AB=3,$ $BC=6,$ $CD=4,$ and $DA=4$. If the length of diagonal $AC$ is an integer, what are all

Natalka [10]

<h3>Answer:</h3>

AC ∈ {4, 5, 6, 7}

<h3>Explanation:</h3>

When two sides of a triangle are specified, the allowable values for the length of the third side are between the sum and difference of the given sides.

In ∆ACD, sides DA and CD are both given as length 4. Thus the possible range of values for side AC is 0 – 8. The extremes of this range result in ∆ACD having zero area, so we assume they are not of interest.

In ∆ACB, sides AB and BC are given as having lengths 3 and 6. Thus the possible range of values for side AC is 3 – 9. The extremes of this range result in ∆ACB having zero area, so we assume they are not of interest.

The integers that are in both ranges and that give triangles with non-zero area are ...

... AC ∈ {4, 5, 6, 7}

lesya [120]

Hey friend!
You stuck?

There are two inner planets that have no moon. Mercury, and Venus. Only Mercury has hardly any atmosphere. Therefore, Planet A is Mercury. Venus which is composed primarily of carbon dioxide with a small amount of nitrogen is considered a planet with a dense atmosphere. Therefore, Planet B is Venus.

Hope this helps! {Don't forget Brainliest!} :)

Should you generate electricity with our own personal wind turbine? That depends on whether you have enough wind on your site. T

aksik [14]

To solve this problem, first we have to determine the z statistic. The formula is

$z= \frac{x-mean}{s \sqrt{n} }$

where x is the test point which is 8.019, the mean is 8 mph, s is the standard deviation which is 3.813 and n is the number of data which is 1114. Then,

$z= \frac{8.019-8}{ \frac{3.813}{ \sqrt{1114}} }= 0.17$

Next, we find the p-value for the particular z. p-value is used in hypothetical test. Using a wind turbine would be the null hypothesis. From the standard normal table found in any statistics book, the p-value for z<0.17 is 0.5675. If the p-value is greater than 0.05, then you do not reject the null hypothesis.

Therefore, the landowner could use a small turbine at the site.
