First off, I would like to say that you aren't d**b! Always remember that asking for help is never d**b!
To change a fraction to a decimal, put the decimal over its place value. For example, if you had the decimal 0.7, you would put 7 over 10 to create the fraction [tex]\frac{7}{10}[/tex].
Lastly, always remember to simplify your answer!
Hope this helps! Have a great day! (:

A line for tickets to a Broadway show had a mean waiting time of 20 minutes with a standard deviation of 5 minutes.
What percentage of the people in line waited for more than 28 minutes?
Answer:
5.48% of the people in line waited for more than 28 minutes
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean waiting time of 20 minutes with a standard deviation of 5 minutes.
This means that [tex]\mu = 20, \sigma = 5[/tex]
What percentage of the people in line waited for more than 28 minutes?
The proportion is 1 subtracted by the p-value of Z when X = 28. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{28 - 20}{5}[/tex]
[tex]Z = 1.6[/tex]
[tex]Z = 1.6[/tex] has a p-value of 0.9452.
1 - 0.9452 = 0.0548.
As a percentage:
0.0548*100% = 5.48%
5.48% of the people in line waited for more than 28 minutes

Use the definition of a Taylor series to find the first four nonzero terms of the series for f(x) centered at the given value of a. (Enter your answers as a comma-separated list.) f(x) = 7xex, a = 0
Answer:
The four first terms are:
[tex]7x,7x^{2},\frac{21x^{3}}{6},\frac{7x^{4}}{6}[/tex]
Step-by-step explanation:
The function is:
[tex]f(x)=7xe^{x}[/tex]
The Taylor series around a is given by:
[tex]F(x)=\sum^{\infty}_{n=0} \frac{f^{n}(a)(x-a)^{n}}{n!}[/tex]
The first 4 terms will be:
[tex]F(x)=f(0)+\frac{f^{'}(0)(x)}{1}+\frac{f^{''}(0)(x)^{2}}{2}+\frac{f^{'''}(0)(x)^{3}}{6}[/tex]
Let's find first the derivatives:
[tex]f'(x)=7(xe^{x}+e^{x})[/tex]
[tex]f'(0)=7(0e^{0}+e^{0})=7[/tex]
[tex]f''(x)=7xe^{x}+7e^{x}+7e^{x}=7xe^{x}+14e^{x}[/tex]
[tex]f''(0)=14[/tex]
[tex]f'''(0)=21[/tex]
[tex]f''''(0)=28[/tex]
[tex]F(x)=0+\frac{7(x)}{1}+\frac{14(x)^{2}}{2}+\frac{21(x)^{3}}{6}+\frac{28(x)^{4}}{24}[/tex]
Therefore, the four first terms are:
[tex]7x,7x^{2},\frac{21x^{3}}{6},\frac{7x^{4}}{6}[/tex]
I hope it helps you!
So the Taylor series for the function informed will be:
[tex]7x; 7x^2; \frac{21x^3}{6} ; \frac{7x^4}{6}[/tex]
The function is:
[tex]f(x)= 7e^xx[/tex]
The Taylor series around a is given by:
[tex]f(x)= \sum \frac{f^n (a) (x-a)^n }{n!}[/tex]
The first four terms will be:
[tex]F(x)=f(0)+\frac{f'(0)(x)}{1}+\frac{f''(0)(x)^2}{2} + \frac{f'''(0)(x)^3}{6}[/tex]
Let's find first the derivaties:
[tex]f'(x)= 7(e^xx+e^x)\\f'(0)= 7\\f''(x)= 7e^xx+14e^xx\\f''(0)=14\\f'''(0)= 21\\f''''(0)= 28[/tex]
[tex]F(x)= 0+\frac{7x}{1}+\frac{14x^2}{2}+\frac{21x^3}{6}+\frac{28x^4}{24}[/tex]
Therefore, the four first terms are:
[tex]7x; 7x^2; \frac{21x^3}{6} ; \frac{7x^4}{6}[/tex]

A new game system was priced at $500 when it was introduced to the market. Over the
next few years, the cost decreased by 7% each year. What was the cost of the gaming
system after two years?
Answer:
FV= $436.72
Step-by-step explanation:
Giving the following information:
Initial cost (PV)= $500
Decrease rate (d)= 7% per year
Number of periods (n)= 2 years
To calculate the future value after 2 years, we need to use the following formula:
FV= PV / (1 + d)^n
FV= 500 / (1.07^2)
FV= $436.72
Abigail is going to cover the label on a Pringle's can and decorate it for
Mother's Day. The can has a diameter of 4.5 inches and a height of 14
inches. What is the minimum amount of paper that she needs for the
project?
Answer:
[tex]Area = 229.6125in^2[/tex]
Step-by-step explanation:
Given
[tex]h = 14in[/tex] --- height
[tex]d =4.5in[/tex] --- diameter
Required
The minimum amount of paper needed
This implies that we calculate the surface area of the can (cylinder)
This is calculated as:
[tex]Area = 2\pi r(r + h)[/tex]
Where
[tex]r = \frac{1}{2}d[/tex]
So, we have:
[tex]r = \frac{1}{2} *4.5[/tex]
[tex]r = 2.25[/tex]
This gives:
[tex]Area = 2 * 3.14 * 2.25(2.25 + 14)[/tex]
[tex]Area = 2 * 3.14 * 2.25*16.25[/tex]
[tex]Area = 229.6125in^2[/tex]

Answer:
19 would be the naswer
Step-by-step explanation:
If mSW = (12x-5)°, mTV= (2x+7)°,and m angle TUV = (6x-19)°, find mSW
Given:
Consider the below figure attached with this question.
m(arc(SW)) = (12x-5)°, m(arc(TV))= (2x+7)°,and measure of angle TUV = (6x-19)°.
To find:
The m(arc SW).
Solution:
Intersecting secant theorem: If two secants intersect outside the circle, then the angle on the intersection is half of the difference of the larger subtended arc and smaller subtended arc.
Using Intersecting secant theorem, we get
[tex]m\angle TUV=\dfrac{1}{2}(m(arc(SW))-m(arc(TV)))[/tex]
[tex]6x-19=\dfrac{1}{2}((12x-5)-(2x+7))[/tex]
[tex]6x-19=\dfrac{1}{2}(12x-5-2x-7)[/tex]
[tex]6x-19=\dfrac{1}{2}(10x-12)[/tex]
Multiply both sides by 2.
[tex]2(6x-19)=10x-12[/tex]
[tex]12x-38=10x-12[/tex]
[tex]12x-10x=38-12[/tex]
[tex]2x=26[/tex]
Divide both sides by 2.
[tex]x=13[/tex]
Now, the measure of arc SW is:
[tex]m(arc(SW))=(12x-5)^\circ[/tex]
[tex]m(arc(SW))=(12(13)-5)^\circ[/tex]
[tex]m(arc(SW))=(156-5)^\circ[/tex]
[tex]m(arc(SW))=151^\circ[/tex]
Therefore, the measure of arc SW is 151 degrees.

The temperature in a commercial freezer over four days are -2.36 F, 1.68F, -1.81F, and 0.67F what is the mean temperature of the freezer over the four days
Answer: -0.455F
Step-by-step explanation:
The mean temperature of the freezer over the four days will be gotten by adding the total temperature and then dividing by 4. This will be:
= (-2.36 + 1.68F + -1.81F + 0.67F) / 4
= -1.82F/4
= -0.455F
The mean temperature is -0.455F
