Answer:
-- State-A . . . Population = 1 · (1.08)ˣ
-- State-B . . . Population = 2 · (1.08)ˣ
' x ' = number of years after the original population
At the beginning, x=0.
Any quantity raised to the zero power = 1.
At the beginning, when x=0, the original populations were
State-A = 1 · 1 = 1
State-B = 2 · 1 = 2
The original population of State A was half of
the original population of State B.

Decide if the following statement is true or false. Explain why. It is possible to have a standard deviation of 445,000.
Answer:
TRUE
Step-by-step explanation:
Standard deviation is defined as the measure of spread. In other words, it shows and determines how spread out the numbers are, i.e. the amount of dispersion or variation of a given set of numbers.
The standard deviation ranges from zero to any number. So it is possible to have a standard deviation of number 445,000 because the standard deviation can be of any value greater than or equal to zero.
Using the standard deviation concept, it is found that since the standard deviation is always a positive value or zero, the statement is true.
What is the standard deviation of a data-set?The standard deviation is given by the square root of the sum of the differences squared of each observation and the mean, divided by the one less than the number of values.It always assume a positive value or zero.Hence, considering that the standard deviation is always a positive value or zero, the statement is true.

A carpenter has a wooden that measures 1/4 meter long. He must cut the board into 6 pieces of equal length. How long in meters should the carpenter cut each piece.
Answer:
1/26 meter
Step-by-step explanation:
You would start by dividing 1/4 by 6. You'd have to multiply 1/4 by the reciprocal of 6 (the reciprocal of 6 would be 1/6). Then you get (1/4) * (1/6), which is equal to 1/24.
Carpenter should cut each piece of wooden board measuring [tex]\frac{1}{24}[/tex] meter.
Let the length of each piece = x meters
Since, the number of pieces (of equal length) of the wooden board = 6
Therefore, total length of wooden board = 6x
It's given in the question that the length of the wooden board is [tex]\frac{1}{4}[/tex] meter.
Therefore, 6x = [tex]\frac{1}{4}[/tex]
[tex]\frac{6x}{6}=\frac{1}{4\times 6}[/tex]
[tex]x=\frac{1}{24}[/tex] meter
Hence, carpenter should cut each piece of wooden board measuring [tex]\frac{1}{24}[/tex] meter.

A bicycle is on sale for 20% off. The bicycle regularly costs 129.95 What is the sale price
Calculator Use
Calculate the sale price you will pay for an item based on the type of discount in the sale promotion:
Percent off list price
Fraction off list price
Multi-item discount
You can also compare discounts to find the lowest price for an item. Enter a percentage off price, fraction off price, multiple items for the price of one or other "two-for" type discounts. Compare the final discounted price for each in the answer table.
Delete any pricing inputs you don't need for your calculations.
Sale Price Formulas and Calculations
Percent Off Price Formula
Discounted price = List price - (List price x (percentage / 100))
Example: Sale price is 25% off list price of $130
Convert 25% to a decimal by dividing by 100: 25/100 = 0.25
Multiply list price by decimal percent: 130*0.25 = 32.50
Subtract discount amount from list price: 130 - 32.50 = 97.50
With the formula:
130 - (130*(25/100)) =
130 - (130*0.25) =
130 - 32.50 = 97.50
25% off $130 is $97.50
Answer:
103.96
Step-by-step explanation:
100% (full price) --> 129.95
80% (retail price = 100%(full price) - 20% (discount)) --> x
x = 80*129.95/100 = 103.96

Amy has 20 necklaces in a jewelry box. The probability of reaching into the jewelry box and pulling out a silver necklace is 0.85. What is the probability that Amy will reach in the jewelry box and pull out a necklace that is not silver?
Answer:
0.15
Step-by-step explanation:
Given
[tex]Necklaces = 20[/tex]
Represent the probability of pulling out silver with p; So:
[tex]p = 0.85[/tex]
Required
Determine the probability of not pulling silver
This question is to test probability complements
And the complement rule of probability states that:
[tex]p + q = 1[/tex]
Where q and p are opposites. In other words:
q = probability of not pulling out silver
Substitute 0.85 for p in [tex]p + q = 1[/tex]
[tex]0.85 + q = 1[/tex]
Make q the subject
[tex]q = 1 - 0.85[/tex]
[tex]q = 0.15[/tex]
Hence, the required probability is 0.15

0.12 cubic meters of silver which she needs to make into 9.9e4 coins of thickness 2 mm. If she uses all of the silver, what is the diameter in centimeters of each coin
Answer:
The diameter of each coin is approximately 2.778 centimeters.
Step-by-step explanation:
According to the statement, 0.12 cubic meters ([tex]1.20\times 10^{8}\,mm^{3}[/tex]) were used to produce 99000 coins. First, we calculate the volume of each coin ([tex]V_{c}[/tex]), measured in cubic meters, by dividing the total volume by the number of coins. That is:
[tex]V_{c} = \frac{1.20\times 10^{8}\,mm^{3}}{99000}[/tex]
[tex]V_{c} =1212.121\,mm^{3}[/tex]
Then, diameter ([tex]D[/tex]), measured in milimeters, can be derived from the following volume formula:
[tex]V_{c} = \frac{\pi}{4}\cdot D^{2}\cdot h[/tex] (1)
Where [tex]h[/tex] is the thickness of the coin, measured in milimeters.
If we know that [tex]h = 2\,mm[/tex] and [tex]V_{c} =1212.121\,mm^{3}[/tex], then the diameter of each coin is:
[tex]D^{2} = \frac{4\cdot V_{c}}{\pi\cdot h}[/tex]
[tex]D = 2\cdot \sqrt{\frac{V_{c}}{\pi\cdot h} }[/tex]
[tex]D = 2\cdot\sqrt{\frac{1212.121\,mm^{3}}{\pi\cdot (2\,mm)} }[/tex]
[tex]D \approx 27.779\,mm[/tex]
The diameter of each coin is approximately 2.778 centimeters.
You deposit $2,500 in a special savings account. The account earns interest at a rate of 3.25% compounded monthly. a. What amount will be in your account at the end of 5 months is no other deposits or withdrawals are made? b. What is the compound interest?
Answer:
1. $2906.25
2. $406.25
Step-by-step explanation:
2500+ (3.25% of 2500) (5)
2500+ (81.25) (5)
2500+ $406.25
=2906.25
3.25% of 2500
=406.25
The required solution,
(a) Amount in the account after 5 months will be $2,933.53.
(b) Compound interest = $433.53.
Compound interest is the interest on deposits computed on both the initial principal and the interest earned over time.
Amount = principal[1 + r/n]ⁿᵃ
Principal = P rate= r Time =a , n = compounding frequency
Amount = 500[1 + 0.0325/12]⁵
Amount = $2,933.53
Compound interest = Amount - principal
= 2933.53 - 2500
= $433.53
Thus, the required solution,
(a) Amount in the account after 5 months will be $2,933.53.
(b) Compound interest = $433.53.

You work as a bank manager. Applicants for tellers jobs took a skills test and their scores are listed in the chart shown. To compare the group of applicants with groups for other positions, you need to find their average scores. What was the average score on the test for this group?
You haven't listed the information in the table, but that's okay :). I believe I can still help you.
To find the average score on the test for this group you would have to add up all the test scores listed in the chart, then divide that sum by the number of people in the group.
Here's an example;
I'll make a list of people with some test scores
Jimmy- 80
Andrea- 44
Samuel- 15
Jerica- 65
To find the average of their scores, I'll first add up their points:
80+44+15+65 = 204
Once I've calculated my sum, I will divided that sum by the number of people who took the test. In this case it's 4 different people, so :
204÷4= 51
So in my made up scenario the average score in my group was 51.
Now you can apply this process into your problem.
(Hope this helps :). Please let me know if you need more help on this problem)
