Formulate the indicated conclusion in nontechnical terms. Be sure to address the original claim.The owner of a football team claims that the average attendance at games is over 523 , and he is therefore justified in moving the team to a city with a larger stadium. Assuming that a hypothesis test to support this claim has been conducted and that the conclusion is failure to reject the null hypothesis, state the conclusion in nontechnical terms.
Answer:
The statement that the mean attendance is higher than 523 does not have enough facts to stand up.
What is null hypothesis?
A null hypothesis is an educated guess or a prediction of the expected outcome of a particular experiment. It is a statement that assumes there is no difference between two groups or no association between two variables. The null hypothesis is often the opposite of the alternative hypothesis, which is the prediction that the researcher is hoping to prove.
Example 1: In a study of the effectiveness of a new drug for treating depression, the null hypothesis would be that the drug has no effect on depression levels.
Example 2: In a study of the association between smoking and lung cancer, the null hypothesis would be that there is no association between the two variables.
Example 3: In a study of the effect of a new educational program on student performance, the null hypothesis would be that the program has no effect on student performance.

They can claim the credit for child and dependent care expenses. What is their eligible amount of work-related daycare expenses?
The eligible amount of work-related daycare expenses will be $2600
What is MFJ?Married filing jointly is a filing status for married couples, allowing them to file joint tax returns. When filing taxes under married filing jointly status, a married couple can record their respective incomes, deductions, credits, and exemptions on the same tax return.
Given here wages of the cliff are $16,228 and if the deb is $2,600
now the mfj is 35% hence cliffs credit is 35% × $16,228 = $5679.8
and daycare yearly expenses are = $250×12
= $3000
but deb's income is $2600 and thus credit cannot exceed deb's wages therefore the revised credit would be $2600
Hence, the eligible amount of work-related daycare expenses will be $2600

Step-by-step explanation:
v\a special window has the shape of a rectangle surmounted by an equilateral triangle. see the figure. if the perimeter of the window is 16 feet, what dimensions will admit the most light?
The dimension of rectangle window to admit the most light is x = 16 / ( 8 - √3) and y = 24 - 8√3 / 8 - √3
According to the question,
The perimeter of the window is 16 feet
Also, Window is surmounted by an equilateral triangle
Let x and y be the dimensions of rectangular part of window and x be side of equilateral part. If A be the total area of window, then
A = x.y + (√3/4)x² -------------(1)
Also, x + 2y + 2x = 16
=> 3x + 2y= 16
=> y = 16-3x / 2
Replacing the value of y in equation (1)
=> A = x.(16-3x / 2) + (√3/4)x²
=> A = 8x - 3x²/2 + (√3/4)x²
Differentiating A w.r.t x
=> A' = 8 - 3x + (√3/2)x
For critical value , we put A'=0
=> 8 - 3x + (√3/2)x = 0
=> x = 16 / ( 8 - √3)
Again, Differentiating A' w.r.t x ,
=> A'' = -3 + √3/2
which is Less than 0 ,
Therefore , A is maximum if x = 16 / ( 8 - √3) and y = 24 - 8√3 / 8 - √3
Hence, For admitting the most light the area should be largest , dimensions of rectangle are x = 16 / ( 8 - √3) and y = 24 - 8√3 / 8 - √3

Clarks Inc., a shoe retailer, sells boots in different styles. In early November the company starts selling “SunBoots” to customers for $70 per pair. When a customer purchases a pair of SunBoots, Clarks also gives the customer a 30% discount coupon for any additional future purchases made in the next 30 days. Customers can’t obtain the discount coupon otherwise. Clarks anticipates that approximately 20% of customers will utilize the coupon, and that on average those customers will purchase additional goods that normally sell for $100.
Required:
1. How many performance obligations are in a contract to buy a pair of SunBoots?
2. Assume Clarks cannot estimate the standalone selling price of a pair of SunBoots sold without a coupon. Prepare a journal entry to record revenue for the sale of 1,000 pairs of SunBoots.

2. The journal entry to record the revenue for the sale of 1,000 pairs of SunBoots when Clarks cannot estimate the standalone selling price of a pair of SunBoots sold without a coupon is as follows:
Journal Entry:Debit Cash $70,000
Credit Sales Revenue $65,800
Credit Deferred Revenue from Discount Coupon $4,200
(To record the sale of 1,000 pairs of SunBoots, including the discount coupon.)
What are performance obligations?Performance obligations refer to distinct goods and services agreed to be provided in a contract between the two parties.
Performance obligations arise because each separate goods or services benefit the customer distinctly from others.
In accounting for the revenue or costs, efforts should be geared toward recognizing the activity as soon as they bestow or transfer economic benefits to the buyer.

2x - 5 = 45 ( add 5 to both sides )
2x = 50 ( divide both sides by 2 )
x = 25

(ii) each person is asked for their top two choices, and the alternative that is chosen by the maximum number of people is selected. (iii) the group uses the Borda count with 5 points for the most preferred alternative, and 1 point for the least preferred alternative. (iv) the group follows a dot-voting scheme, where each person gets 10 "dots", and they assign the number of dots to each alternative that are roughly proportional to their Utility. (v) the group uses the "maximin rule" which prescribes that the group should prefer the alternative in which the worse-off person is as well-off as possible.
(vi) the sum of individual utilities is maximized for the group. Discuss the pros and cons of the group decision making methods listed above.
(ii) each person is asked for their top two choices, and the alternative that is chosen by the maximum number of people is selected
the best is always to look for points on the line that are exactly corner points of grid squares.
the true utilities of the four individuals for the five alternatives
(0.3, 0.4) and (0.6, 0.8)
so, the linear equation is
y = ax + b
0.4 = a×0.3 + b
0.8 = a×0.6 + b
let's subtract the second from the first equation :
-0.4 = a×-0.3 + 0
a = -0.4/-0.3 = 0.4/0.3 = 4/3
so, the equation is
y = (4/3)x

Find the 13th term in the following
arithmetic sequence :
2, 5, 8, 11, .
The 13th term of the given Arithmetic sequence is 38.
Arithmetic sequence:A list of integers with a distinct pattern is known as an arithmetic sequence. It is an arithmetic sequence if you can subtract any number in the sequence from the one before it and get a value that is either constant or always the same. Here the constant value is called a common difference.
The formula for the nth term of the Arithmetic sequence is given by
a[tex]_{n}[/tex] = a+(n-1)dHere we have
Arithmetic sequence: 2, 5, 8, 11,....
Where first term a = 2
And common difference d = term2 - term 1 = 5 - 2 = 3
As we know nth term of AP = a + (n-1)d
=> 13th term of AP = a + (13-1)d = a + 12d
From the give data, a = 2 and d = 3
=> 13th term = a + 12d
= 2 + 12(3)
= 2 + 36
= 38
Therefore,
The 13th term of the given Arithmetic sequence is 38

18. A living room set lists for $2,400 and carries a trade discount of 30%. Freight charges are $200. Calculate the final price of the living room set.
A. $1,880
B. $1,800
C. $1,008 D. $8,100
Answer: The final price of the living room set is $1,880 (Option A)
Step-by-step explanation: Market price of living room set = $2400
Trade Discount offered= 30%
Therefore we deduct Trade Discount from the Market Price to arrive at the final price.
= 2400 - (2400*30%)
=2400-720
=1680
Freight charges incurred to bring an asset to use are added to the final price of the asset.
Therefore the Final Price = 1680+200
=$1,880

Which statement is true about the functions f(x)=-15x^2+32 and g(x)=-17x^2+5x+32? a. f(x) and g(x) have the same zeros. b. f(x) has a higher maximum than g(x). c. f(x) and g(x) have the same y intercept. d. f(x) and g(x) are odd functions.
None of the options are valid because the specified functions are both parabolic.
Explain about the Functions?Functions represent the connection between two groups of values. For instance, if y=f(x), each value of x has a corresponding value in the set of y. The dependent variable is Y, and the independent variable is x.
An example of a rule is a function, which produces one output for a single input. Alex Federspiel is the picture's author. Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x. In mathematics and the sciences, functions are fundamental for constructing physical relationships.
Given functions in this case are
f(x)=-15x2+32
g(x)=-17x2+5x+32.
The functions' zeros are
x = 1.461, -1.233, and 1.527.
When g(x) has a higher maximum than f(x), f(x)intercept exceeds g. (x).

A husband and wife plan to save money for their daughter's college education in 5 years. They decide to purchase an annuity with a semiannual payment earning 10.5% compounded semiannually. Find the future value of the annuity in 5years if the semiannual payment is $3150. Round your answer to the nearest cent.
The future value of the annuity is ?
Answer:
$40,601.92
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 1.5/100
r = 0.015 per year,
Then, solve the equation for P
P = I / ((1 + r/n)nt - 1)
P = 3150 / ((1 + 0.015/2)(2)(5) - 1)
P = 3150 / ((1 + 0.0075)(10) - 1)
P = $40,601.92
Summary:
The principal investment required to get a total interest of $3150 from compound interest at a rate of 1.5% per year compounded 2 times per year over 5 years is $40,601.92.

Light rail or bus, but not carpool: 10%.Carpool and bus: 0%.Did not answer light rail, carpool or bus: 72%.Exactly one: 21%.Light rail, carpool, or bus: 28%.How to fill the Venn Diagram?The Venn Diagram is filled starting at the intervals involving most variables, that is, the intersections.
2% of people answered all three, hence space V on the diagram has a value of 2%, which is the intersection of the three sets.
3% of people answered light rail and bus, hence space IV has a value of 1%, as light rail and bus also involve light rail, bus and carpool.
6% of people answered light rail and carpool, hence space II has a percentage of 4%, following the same logic above.
2% of people answered carpool and bus, hence space V has a percentage of 0%.
11% of people answered carpool, hence space III has a percentage of 5%, as this percentage is a combination of:
Carpool and bus.Carpool and rail.Carpool, bus and rail.Only carpool.From the total bus and light rail percentages, the percentages are given as follows:
VI = 7%.I = 9%.The percentage of people that use at least one of these mediums is given as follows:
9 + 7 + 5 + 1 + 2 + 4 = 28%.
The percentage of people who use none of these mediums is given as follows:
100 - 28 = 72%.
Then the missing percentages at the end of the problem, along with their spaces, are given as follows:
