The positions of the peaks and dips in its spectrum provide evidence about the ELEMENTAL COMPOSITION of an object. Each element can absorb light at determined wavelengths.
Each element can absorb light rays at determined wavelengths because elements are composed of different atoms.
Spectroscopy is a field of study focused on the interaction between the atoms of an element and electromagnetic radiation as a function of the wavelength.
This field (spectroscopy ) studies the absorption and emission spectra of light by matter, which can be used to determine the elemental composition of an object.

Ms. Sanchez’s students were asked how many hours they spend participating in organized sports each week. Each row of the table represents one sample from the class. Number of hours playing sports 5 5 3 0 6 2 2 4 5 2 3 4 3 0 1 4 0 4 3 6 what is the mean of the sample in the third row? 2. 2 2. 8 3. 0 3. 4.
The mean of a dataset is the average of the dataset.
The mean of the sample in the third row is 2.2
The dataset is given as:
5 5 3 0 6 2 2 4 5 2 3 4 3 0 1 4 0 4 3 6
From the complete question, the samples in the third row are:
Sample: 3 4 3 0 1
The mean of a dataset is calculated using:
[tex]\bar x = \frac{\sum x}{n}[/tex]
Where:
n = 5 i.e. the number of samples
So, we have:
[tex]\bar x = \frac{3 + 4 + 3 + 0 + 1}{5}[/tex]
Add the expressions in the numerator
[tex]\bar x = \frac{11}{5}[/tex]
Divide 11 by 5
[tex]\bar x = 2.2[/tex]
Hence, the mean of the sample in the third row is 2.2

The cost of mailing a first-class letter is $0. 46.
Answer:
Explanation:
If y is the total cost to mail a letter, that is what your equation should be set equal to.
y = _________
Then, just to be able to send the letter, you have to pay .46 before you even weigh it.
y = 0.46 + _____
Finally, you can weigh your letter to determine how much more you'd have to pay (it wouldn't be fair if a 1 ounce letter and a 5 pound letter costed the same!). The problem gives you the variable for ounces, so you would do
price x ounces.
y = 0.46 + 0.20x
(I'm not sure what the name of the equation is, but it is in y = mx + b form. I believe it is "slope intercept"? That should be somewhere in your notes. Hope this helps :) )

A piece of equipment costs $30,000, and is expected to generate $8,500 of annual cash revenues and $1,500 of annual cash expenses. The disposal value at the end of the estimated 10-year life is $3,000. Ignoring income taxes, the payback period is:.
Answer:
C. 4.29 years
Explanation:
The computation of the payback period is shown below:
Payback period = Initial investment of the equipment ÷ Cash flows
where,
Initial investment = $30,000
And, the cash flows is
= $8,500 - $1,500
= $7,000
So the payback period is
= $30,000 ÷ $7,000
= 4.29 years
By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.

Which of the following would have the largest concentration of chloride ions in solution.
Answer:
From the given options, the solution of 0.10M AlCl₃ is the one that has the highest concentration of chloride ions.
To know which of the given solutions has the highest concentration of chloride ions, we must evaluate each of them.
1) 0.10 M MgCl₂
We can see that in 1 mol of MgCl₂, we have 1 mol of Mg²⁺ and 2 moles of Cl⁻ ions, so if the initial concentration of MgCl₂ is 0.10 M we have:
Hence, in this solution we have 0.20 M of chloride ions.
2) 0.10 M AlCl₃
In 1 mol of AlCl₃, we have 1 mol of Al³⁺ and 3 moles of Cl⁻, so the concentration of Cl⁻ is:
Then, the concentration of chloride ions in this solution is 0.30 M.
3) 0.05 M CaCl₂
We can notice that in 1 mol of CaCl₂ we have 1 mol of Ca²⁺ and 2 moles of Cl⁻. The concentration of Cl⁻ is:
So, the concentration of the Cl⁻ ions is 0.10 M.
4) 0.10 M LiCl
In this case, in 1 mol of LiCl we have 1 mol of Li⁺ and 1 mol of Cl⁻, so the concentration of the chloride ions is:
Hence, in this solution the concentration of the Cl⁻ ions is 0.10 M.
Therefore, the solution 0.10M AlCl₃ has the highest concentration of chloride ions.

Answer: A Binomial distribution apply when we have n identical and independent events with two possible results, success or fail, and a probability p of success and 1-p of fail. Then, the probability that from the n events, x are success is:
Then, the number of motorist driving more than 5 miles per hour over the speed limit follow a Binomial Distributions, because we have 4 randomly selected motorists with two possible options: they are driving more than 5 miles per hour over the speed limit or they aren't, and the probability that they are driving more that 5 miles per hour over the speed is 0.4.
Finally, the probability P that among 4 randomly selected motorists, the officer will find at least 1 motorist driving more than 5 miles per hour over the speed limit is:
P = P(1) + P(2) + P(3) + P(4)
Where n is equal to 4 and p is equal to 0.4. Replacing the values for every x, we get:
Finally, P is equal to:
P = 0.3456 + 0.3456 + 0.1536 + 0.0256
