Answer: 2192.08
Step-by-step explanation:
6/100=0.06
1 - 0.06= 0.94
1 + 0.06= 1.06
2200*094*1.06= 2192.08
The value of the stock at the end of the second day is $2192.08.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Value of stock = $2200
At the end of the first day →
6% decrement
6$ of 2200 ⇒ 2200 × 6/100 = 132
So,
2200 - 132 = $2068
At the end of the second day →
6% increment
6$ of 2068⇒ 2068× 6/100 = 124.08
So,
2068 + 124.08= $$2192.08
Hence "The value of the stock at the end of the second day is $2192.08".

(1) The ratios 18:3 and 6:1 are equivalent. Why?
Answer:
Because if you take 18:3 and divide both sides by 3, you will get 6:1
Step-by-step explanation:
Because 18:3 divided by 3 on both sides equals 6:1, also 6:1 times 3 on both sides equals 18:3.
An Airbus A320 jet flies 5 hours west with a 40-mph tailwind. Returning against the wind takes 7 hours. Find the speed of the jet with no wind.
Answer:
The speed of the jet with no wind is 240 miles per hour.
Step-by-step explanation:
The speed of the jet with no wind is equivalent to the speed of the jet relative to wind. Physically speaking, we have the following system of linear equations under the assumption that both speeds of wind and jet are constant:
In favor of wind
[tex]\frac{s}{t_{F}} = v_{W}+v_{J/W}[/tex] (1)
Against wind
[tex]-\frac{s}{t_{A}} = v_{W} -v_{J/W}[/tex] (2)
Where:
[tex]s[/tex] - Travelled distance, measured in miles.
[tex]t_{F}[/tex], [tex]t_{A}[/tex] - Time, measured in hours.
[tex]v_{W}[/tex] - Wind speed, measured in miles per hour.
[tex]v_{J/W}[/tex] - Jet speed relative to wind, measured in miles per hour.
If we know that [tex]t_{F} = 5\,h[/tex], [tex]t_{A} = 7\,h[/tex], [tex]v_{W} = 40\,\frac{mi}{h}[/tex], then the speed of the jet with no wind is:
[tex]\frac{s}{5} = 40 + v_{J/W}[/tex] (3)
[tex]-\frac{s}{7} = 40-v_{J/W}[/tex] (4)
[tex]\frac{s}{5}-40 = 40 +\frac{s}{7}[/tex]
[tex]\frac{s}{5}-\frac{s}{7} = 80[/tex]
[tex]\frac{7\cdot s - 5\cdot s}{35} = 80[/tex]
[tex]2\cdot s = 2800[/tex]
[tex]s = 1400\,mi[/tex]
From (3), we find that speed of the jet with no wind is:
[tex]v_{J/W} = \frac{s}{5}-40[/tex]
[tex]v_{J/W} = \frac{1400}{5}-40[/tex]
[tex]v_{J/W} = 240\,\frac{mi}{h}[/tex]
The speed of the jet with no wind is 240 miles per hour.
Although five of John's answers were incorrect, 90% of his answers were correct. How many questions did John answer in all?
Answer:
John answered 50 questions.
Step-by-step explanation:
Although five of John's answers were incorrect, 90% of his answers were correct.
This means that 5 is 100 - 90% = 10% of the total number of questions, n. So
[tex]0.1n = 5[/tex]
[tex]n = \frac{5}{0.1}[/tex]
[tex]n = 50[/tex]

Radon is a naturally occurring gas and is the second leading cause of lung cancer in the United States. It comes from the natural breakdown of uranium in the soil and enters buildings through cracks and other holes in the foundations. Found throughout the United States, levels vary considerably from state to state. Several methods can reduce the levels of radon in your home, and the Environmental Protection Agency ecommends using one of these if the measured level in your home is above 4 picocuries per liter. Four readings from Franklin County, Ohio, where the county average is 9.32 picocuries per liter, were 5.2, 13.8, 8.6, and 16.8.
Required:
a. Find the mean step-by-step.
b. Find the standard deviation step-by-step.
Answer:
a) mean = 11.1
b) Standard Deviation = 5.191
Step-by-step explanation:
Given the data in the question;
x = 5.2, 13.8, 8.6, and 16.8
sample n = 4
so;
x ( x - mean)²
5.2 34.81
13.8 7.29
8.6 6.25
16.8 32.49
∑ 44.4 80.84
a) Mean
Mean = total sum of the sample divided by the sample size
mean = ∑x / n
we substitute
mean = 44.4 / 4
mean = 11.1
b)
Standard Deviation is the Square root of variance;
Variance = ∑(x-mean)² / n - 1
we substitute from the above table
Variance = 80.81 / 4 - 1
Variance = 80.81 / 3
Variance = 26.94667
now since Standard Deviation is the Square root of variance;
Standard Deviation = √Variance
Standard Deviation = √26.94667
Standard Deviation = 5.191

f'(x) = (-6x² -14x -23)/(x² +5x +2)²
f''(x) = (12x³ +42x² +138x +202)/(x² +5x +2)³
Step-by-step explanation:
The applicable derivative formula is ...
d(u/v) = (v·du -u·dv)/v²
__
f'(x) = ((-x² -5x -2)(4x +4) -(2x² +4x -3)(-2x -5))/(-x² -5x -2)²
f'(x) = (-4x³ -24x²-28x -8 +4x³ +18x² +14x -15)/(x² +5x +2)²
f'(x) = (-6x² -14x -23)/(x² +5x +2)²

Similarly, the second derivative is the derivative of f'(x).
f''(x) = ((x² +5x +2)²(-12x -14) -(-6x² -14x -23)(2(x² +5x +2)(2x +5)))/(x² +5x +2)⁴

12 gallons to 36 gallons. Percent change?
I guess it is 200%
Hope it is correct
Answer:
200.00%Step-by-step explanation:
Here i will show you how to calculate the Percent Change from 12 to 36.
Basically, we are trying to find the change from 12 to 36 in terms of percent. We do this in three steps:
1) Find the difference between 12 and 36 as a number.
2) Divide the result from Step 1 by the starting number 12.
3) Multiply the result you got on step two by 100 to get it in terms of percent.
this can be shotenn sown with a simple formulatso, to find the percent change from 12 to 36, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 12, and Y is the ending number 36 that it changed to. When we enter these numbers into the formula, we get:
((36-12)/12)*100 = 200.00%

200.00%A polling company is trying to estimate the percentage of adults that consider themselves happy. A confidence interval based on a sample size of 180 has a larger than desired margin of error. The company wants to conduct another poll and obtain another confidence interval of the same level but reduce the error to one-third the size of the original sample. How many adults should they now interview
Answer:
They should interview 1620 adults now.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which z is related to the confidence level, [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
In this question:
z wont change, neither will [tex]\sigma[/tex]
We want to increase n as such the margin of error is reduced to one third.
We have that the margin of error is inversely proportional to the square root of the size of the sample, which means that for the margin of error to be reduced to one third, the sample size has to be multiplied by [tex]3^2 = 9[/tex]. So
180*9 = 1620
They should interview 1620 adults now.

The circumference of a circle measures 11.277 ft.
What is the measure of the diameter of this circle?
Answer:
3.590ft
Step-by-step explanation:
We know what the circumference of the circle is, and we need to find its diameter. Therefore, we need to find an equation that links the two together.
Well, what comes to mind is the fact that the circumeference, [tex]c[/tex], is equal to [tex]\pi[/tex] multiplied by the diameter, [tex]d[/tex]. We can express this like so:
[tex]c = \pi d[/tex].
In this scenario, we know what [tex]c[/tex] is, so we need to rearrange the formula to make [tex]d[/tex] the subject. Dividing both sides by [tex]\pi[/tex] will accomplish this, and gives us:
[tex]\frac{c}{\pi} = d[/tex].
So if we divide the circumference by [tex]\pi[/tex], we will find the diamater. Well,
[tex]\frac{11.277}{\pi} = 3.58958...[/tex]
and so to 3 decimal places we get the answer
[tex]d = 3.590\text{ft}[/tex].
