Answer:
Step-by-step explanation:
Midline is the horizontal line that passes exactly in the middle between the graph's maximum and minimum points.
Amplitude is the vertical distance between the midline and one of the extremum points.
Period is the distance between two consecutive maximum points, or two consecutive minimum points (these distances must be equal).
To find the formula for [tex]g(x)[/tex]. First, let's use the given information to determine the function's amplitude, midline, and period.
The midline of a sinusoidal function passes exactly in the middle of its extreme values. So we can find the midline by finding the average of the maximum and minimum values.
The midline passes exactly between the minimum value 1, and the maximum value 11, so the midline equation is
[tex]midline=y=\frac{11+1}{2} =6[/tex]
The extremum points are 5 units above or below the midline, so the amplitude is 5.
The maximum point is 0.5 units to the right of the minimum point, so the period is [tex]2\cdot 0.5 =1[/tex]. We multiply by 2 because the distance between consecutive minimum and maximum points is always [tex]\frac{1}{2}[/tex] of the period.
The general sinusoidal equation [tex]y=a\cos(bx)+d[/tex] is the result of horizontal and vertical shifts, reflections, and stretches of the parent equation [tex]y=\cos(x)[/tex] where
The amplitude is [tex]|a|[/tex].The midline is [tex]y=d[/tex].The period is [tex]\frac{2\pi }{|b|}[/tex].The amplitude is 5, so [tex]|a|=a=5[/tex].
The midline is y = 6, so d = 6.
The period is 1, so b = [tex]\frac{2\pi }{1}=2\pi[/tex].
The formula for [tex]g(x)=5\cos(2\pi x)+6[/tex].

The same Honey is sold in two different size jars. Large jar= 540g for £4.10 Small jar= 360g for £2.81. By considering the amount of honey per penny, work out which jar is the best value for money. Working must be shown.
Answers
Answer:
From our calculations the large jar is the best value for money because a penny buys more honey
Step-by-step explanation:
In this problem we are expected to determine which purchase of honey is the cheapest ? large jar or small jar ?.We will determine which has the best value for money using the quantity a pound can purchase.
firstly for the large jar.
if £4.10 will purchase 540g of honey then,
£1.00 will purchase xg
cross multiplying to find x will have
[tex]x=[/tex] [tex]\frac{1.00*540g}{4.10}[/tex]
[tex]x= 131.7grams[/tex]
Hence for the large jar a penny would buy 131.7g of honey
secondly for the small jar
if £2.81 will purchase 360g of honey then,
£1.00 will purchase xg
cross multiplying to find x will have
[tex]x=\frac{1.00*360g}{2.81}\\x= 128.1gram[/tex]
Hence for the small jar a penny would buy 128.1g of honey
What is the equation of a line , in general form, that passes through points (-1,2) and (5,2)
Answers
Answer:
y-2=0
Step-by-step explanation:
In y=mx+b
m=(y2-y1)/(x2-x1) [2]
Or another way of thinking about it is rise over run.
define point (-1,2) as x1,y1
define point (5,2) as x2,y2
substitute into formula [2]
m=(2-2)/(5-(-1))
We know that 2-2=0 therefore the slope (m) is 0
y=0x+b
Or simply
y=b
to solve for b we substitute into the formula any of the points
2=b for y1
or 2=b for y2
b=2
therefore y=2
to convert it into general form make the equation equal 0
y-2=0

Suppose that, in a hypothesis test, the null hypothesis is in fact true. a. Is it possible to make a Type I error? Explain your answer. b. Is it possible to make a Type II error? Explain your answer.
Answers
Answer:
a. Yes
b. No
Step-by-step explanation:
In a hypothesis test, the null hypothesis is in fact true.
a. Is it possible to make a Type I error?
Yes, it is possible to make a type I error because a type I error typically occurs if the null is rejected when it is actually true.
b. Is it possible to make a Type II error?
It is not possible to make a type II error because the condition for a type II error is that the null is in fact not true but we fail to reject it.

A factor in determining the usefulness of an examination as a measure of demonstrated ability is the amount of spread that occurs in the grades. If the spread or variation of examination scores is very small, it usually means that the examination was either too hard or too easy. However, if the variance of scores is moderately large, then there is a definite difference in scores between "better," "average," and "poorer" students. A group of attorneys in a Midwest state has been given the task of making up this year's bar examination for the state. The examination has 500 total possible points, and from the history of past examinations, it is known that a standard deviation of around 60 points is desirable. Of course, too large or too small a standard deviation is not good. The attorneys want to test their examination to see how good it is. A preliminary version of the examination (with slight modifications to protect the integrity of the real examination) is given to a random sample of 21 newly graduated law students. Their scores give a sample standard deviation of 68 points. Using a 0.01 level of significance, test the claim that the population standard deviation for the new examination is 60 against the claim that the population standard deviation is different from 60.
(a) What is the level of significance?
(b) Find the value of the chi-square statistic for the sample. (Use 2 decimal places.) What are the degrees of freedom?
Answers
Answer:
Step-by-step explanation:
From the information given :
The null hypothesis [tex]H_o : \sigma = 60[/tex]

the sample size n = 21
sample standard deviation s = 68
population standard deviation σ = 60
a) The level of significance [tex]\alpha =0.01[/tex]
b) The chi-square statistics can be calculated as:
[tex]\bar X = \dfrac{(n-1)s^2}{\sigma^2}[/tex]
[tex]\bar X = \dfrac{(21-1)68^2}{60^2}[/tex]

The campus bookstore knows from the past several semesters that a certain elementary statistics book has a demand that is approximated by a normal distribution with a mean of 250 and a standard deviation of 40. They buy these books for $105 each and sell them to unsuspecting undergraduates at $222 each. All demand for this book is realized by the middle of the semester, at which point the bookstore bundles them up and sells them to a vendor in another country for $40 each. What is the marginal profit for a single elementary statistics book
Answers
Answer:
$117
Step-by-step explanation:
Given that:
They buy these books for $105 each and sell them to unsuspecting undergraduates at $222 each
Marginal Profit = Marginal Revenue – Marginal Cost.
Marginal Profit = $222 - $105
Marginal Profit = $117
the marginal profit for a single elementary statistics book $117
For the remaining unsold books in the middle of the semester he bundles them up and sells to vendor in another country for $40 each for which he suffers a marginal loss of $105 - $40 = $65 each

A population of bacteria is initially 6000. After three hours the population is 3000. If this rate of decay continues, find the exponential function that represents the size of the bacteria population after t hours. Write your answer in the form f(t)=a(b)t.
Answers
Answer:
[tex] f(t) = 6000 (\frac{1}{2})^t^/^3 [/tex]
Step-by-step explanation:
Let's take the equation:
[tex] y = y_0 e^-^k^t[/tex]
Given the initial population of bacteria = 6000,
[tex] y = 6000e^-^k^t[/tex]
Population of bacteria after 3 hours is 3000.
y(3) = 3000
Thus,
[tex] 6000e^-^k^3 = 3000[/tex]
[tex] e^-^k^3 = \frac{3000}{6000}[/tex]
[tex] e^-^k^3 = \frac{1}{2}[/tex]
[tex] (e^-^k)^3 = \frac{1}{2}[/tex]
[tex] e^-^k= (\frac{1}{2})^1^/^3[/tex]
Let's substitute [tex] (\frac{1}{2})^1^/^3 [/tex] for [tex] e^-^k[/tex] in [tex] y = 6000e^-^k^t [/tex]
Therefore, we have:
[tex] 6000e^-^k^t [/tex]
[tex] = 6000 [(\frac{1}{2}) ^1^/^3]^t[/tex]
[tex] = 6000 [\frac{1}{2}] ^t^/^3 [/tex]

a. what fraction of the stock of rice did he sell
(a) in February?
(b) in January and February ?
b. How many bags of rice were left unsold, by the end of February?
Answers
Answer:
Kojo had 1800 bags of rice in stock for sale.
In January, he sold 2/3 of it.
=> Number of bag he sold in January: 1800 x 2/3 = 1200
=> The number of bags of rice left: 1800 - 1200 = 600
In February, he sold 3/4 of what was left.
=> Number of bag he sold in February: 600 x 3/4 =450
=> Total number of bags he sold in January and February:
1200 + 450 = 1650
=> The number of bags of rice left at the end of February: 600 - 450 = 150

Consider the polynomials p1(t) = 1 + t , p2(t) = 1 -t , and p3(t) = 2 (for all t). By inspection, write a linear dependence relation among p1, p2, and p3. Then find a basis for Span{ p1 , p2 , p3 }.
Answers
Answer:
[tex]\{p_1,p_2\}$ is a basis of Span\{p_1,p_2,p_3\}[/tex]
Step-by-step explanation:
Given the polynomials:
[tex]p_1(t) = 1 + t\\ p_2(t) = 1 -t\\p_3(t) = 2\\[/tex]
On Inspection
[tex](1+t)+(1-t)=1+1+t-t=2\\$Therefore:\\p_1(t)+p_2(t)=p_3(t)[/tex]
By the Spanning Theorem
If one vector in S is a linear combination of the others, we can delete it and get a subset (one vector smaller) [tex]S' \subseteq S[/tex] that has the same span.
Therefore, since [tex]p_3(t)=p_1(t)+p_2(t)[/tex]
[tex]Span\{p_1,p_2,p_3\}=Span\{p_1,p_2\}[/tex]
[tex]p_1$ and p_2[/tex] are linearly independent because [tex]p_1[/tex] cannot be written in terms of [tex]p_2[/tex].
Therefore, [tex]\{p_1,p_2\}$ is a basis of Span\{p_1,p_2,p_3\}$ as required.[/tex]

This equation shows how the total cost of visiting the art museum as a member is related to the number of visits c= v+7. The variable v represents the number of visits to the art museum and the variable c represents the total cost of those visits. For a member of the art museum, what is the total cost of 10 visits?
Answers
Answer:
17
Step-by-step explanation:
the amount of visits given by the problem is:
[tex]v=10[/tex]
and we have that the equation that relates the number of visits with the total cost is:
[tex]c=v+7[/tex]
where [tex]c[/tex] is the total cost for [tex]v[/tex] number of visits.
We plug into this equation the known value of visitors:
[tex]c=10+7[/tex]
and we solve this expression:
[tex]c=17[/tex]
the total cost for 10 visitors is 17.

Answer:
Step-by-step explanation:
We have to perform one sample proportion test. To do so we have to proceed through following steps.
(1) We have to collect data about vehicle sales in last 20 years.
(2) Using random number table or random number generator or otherwise we have to select sample of vehicles from the list of sale. In this step, we have to keep an eye on the fact that sample is to be selected from all years (all of 20). Using stratified random sampling by dividing vehicles sold over different years is an effective way to do so. That means, we may divide vehicles sold into 20 homogeneous strata over 20 years and select sample from each strata.
(3) After selecting sample of vehicles we have to communicate to corresponding vehicle owners to gather information about that particular vehicle.
(4) We have to note number of vehicles which are still on the road.
Suppose, we have selected n vehicles as sample and after communicating we found that \tiny r of those are still on the road.

A batch of 500 machined parts contains 10 that do not conform to customer requirements. Parts are selected successively, without replacement, until a nonconforming part is obtained. The random variable is the number of parts selected.
Answers
Question:
For the following exercise, determine the range (possible values) of the random variable. A batch of 500 machined parts contains 10 that do not conform to customer requirements. Parts are selected successively, without replacement, until a nonconforming part is obtained. The random variable is the number of parts selected.
Answer:
Possible values are all integers from 1 to 491.
{1,2,...........491}
Step-by-step explanation:
Given:
Total number of machined parts = 500
Number that do not conform to customers requirements = 10
Number that conforms to customers requirements = 500 - 10 = 490
Since, parts are selected successively, without replacement, until a nonconforming part is obtained, the range of the random variable (number of parts selected) here will be all integers from 1 to 491 ie {1,2,...........,491}.
Here, we have a total of 490 conforming parts, and 10 non conforming parts, there must be a non-conforming part among 491 selections, considering the fact that total number of parts are 500
There will be one non-confirming part in the 491 selections and this can be determined by using the given data.
Given :
A batch of 500 machined parts contains 10 that do not conform to customer requirements. Parts are selected successively, without replacement, until a nonconforming part is obtained.Given that the total number of parts is 500 that contains 10 that do not conform to customer requirements. So, the total number of parts that conform to customer requirements is (500 - 10) 490.
It is also given that parts are selected successively, without replacement, until a nonconforming part is obtained so, the range of the random variables is [1,491]
So, there will be one non-confirming part in the 491 selections.

Now we can find the variance with the following formula:
[tex]s^2 =\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}[/tex]
And replacing we got:
[tex] s^2=357.610[/tex]
And the standard deviation would be:
[tex] s = \sqrt{357.610}= 18.911[/tex]
