prove that if all of the 2n subsets of a set containing 2n 1 are equal, then all elements of set n are equal
Answers
when multiplicity is removed, you get 2^(2n+1)/2 members, which is 2^(2n).
Take the power set. It has 2^(2n+1) members.
Replace any member which has n+1 or more elements with its complements.
Now the power set has members, which have n or fewer elements, and each such member appears twice.
Therefore, when multiplicity is removed, you get 2^(2n+1)/2 members, which is 2^(2n).

Answers
The equation which can be used to determine the number of pounds of peaches and crumbles that Stephen could have purchased is 1.8x+2.5y=19.4 and if Stephen purchased 8 pounds of peaches then he also purchased 2 pounds of crumbles.
Given that the cost of peaches is $1.80 per pound and cost of crumbles is $2.50 per pound and the total expenditure done by Stephen is $19.40.
We are required to find the equation that can be used to determine the number of pounds of peaches and crumbles that Stephen could have purchased and find the number of crumbles that Stephen purchased if he had 8 pounds of peaches.
Suppose the number of pounds of peaches be x and the number of crumbles be y.
The equation will be as under:
x*1.80+y*2.50=19.40
1.80x+2.50y=19.40---------1
Put the value of x=8 to find the number of crumbles.
1.8 *8+2.50y=19.40
14.4+2.50y=19.40
2.50y=19.4-14.4
2.50y=5
y=5/2.5
y=50/25
y=2
Hence the equation which can be used to determine the number of pounds of peaches and crumbles that Stephen could have purchased is 1.8x+2.5y=19.4 and if Stephen purchased 8 pounds of peaches then he also purchased 2 pounds of crumbles.

the federal helium reserve held about 20 billion cubic feet of helium in 2010 and is being depleted by about 1.9 billion cubic feet each year. a . give a linear equation for the remaining federal helium reserves in billions of cubic feet, r , in terms of t , the number of years since 2010. r ( t )
Answers
The linear equation for the remaining Federal Helium Reserves, r(t) = 20 -1.9t
There is 20 billion cubic feet of Helium in 2010. Helium is depleted by about 1.9 billion cubic feet each year.
Let 'r' denotes the remaining Federal Helium Reserves in billions of cubic feet.
Let 't' denotes the number of years since 2010.
We have to find a linear equation to represent the depletion of Helium through years since 2010. A linear equation will have two variables, one dependent and one independent variable. Here, let 'r' be the dependent variable and 't' be the independent variable.
Then the amount of Helium depleted in 't' years = 1.9t
So, the remaining Helium in the Federal Helium Reserve since 2010 = 20 - 1.9t.
Thus, r(t) = 20 - 1.9t
This is a linear equation because it depends on only one variable, 't'.

(ANSWER QUICK PLEASE) 1. Kasey noticed that the distribution of candy bars in the variety bags of candy bars is always the same. There are three times as many Twix Bars as Milky Ways. There are 5 fewer snickers than there are Twix.
Answers
Small Snickers :19 (24-5)
Medium Milky Way : 10 (30/3)
Medium snickers : 25. (30-5)
Large Twix: 42 (37+5)
Large Milky Way 14 (42/3)
Hope this helps!
Answer:
Let's call the number of Twix bars "x".
Since there are three times as many Twix bars as Milky Ways, the number of Milky Ways is x / 3.
And, since there are 5 fewer Snickers bars than there are Twix bars, the number of Snickers bars is x - 5.
So, the total number of candy bars can be found by adding the number of each type of candy bar:
x + x / 3 + x - 5 = total number of candy bars
Combining like terms, we get:
5x / 3 - 5 = total number of candy bars
To find the value of x, we can solve this equation for x.
5x / 3 = total number of candy bars + 5
5x / 3 = total number of candy bars + 5
5x = 3(total number of candy bars + 5)
5x = 3(total number of candy bars) + 15
5x = 3(total number of candy bars) + 15
5x - 15 = 3(total number of candy bars)
5x - 15 = 3(total number of candy bars)
(5x - 15) / 3 = total number of candy bars
So, the total number of candy bars can be found by dividing (5x - 15) by 3. The value of x represents the number of Twix bars, and the rest of the candy bars can be found using the relationships described in the problem.

so RS=ST.
Let us say RS = ST = x .
Then, RT= RS + ST= x + x = 2x ,
so RT = QR = 2x
Then, QT = QR+RT = 2x+2x = 4x ,
and PQ = QT = 4x .
Then, PS= PQ+QR+RS=4x+2x+x=7x ,
and PT=PQ+QT=4x+4x=8x

Which weight represents the 65th percentile?
Answers
The 65-th percentile is approximately 83.8 ounces.
A number at or below which a particular percentage falls in its frequency distribution, or a score below which a given percentage falls, is known as the k-th percentile in statistics. The 50th percentile, for instance, is the score at or below which 50% of the distribution's scores can be found.
The 50-th percentile is called the median.The 25th and 75th percentile is called the lower and upper percentile respectively.Mean of a data-set is the measure of central tendency which denotes the average of the data.The standard deviation denotes the fluctuations of the data from the central tendency.The percentile can be calculated by using the formula
Percentile Value = μ + zσ where
z is the z-score , μ is the mean and σ is the standard deviation.
Here the percentile that is to be calculated is 65.
So we take the value that is closest to 0.65 from the z-table.
We get the value of the data to be 0.39
Now putting the values in the equation we get:
Percentile Value = μ + zσ
or, Percentile Value = 83 + (0.39 × 2)
or, Percentile Value = 83.78
or, Percentile Value ≈ 83.8
Hence the 65th percentile value of the function is given by 83.8 .

If f (x) = 3x^4+5, then what is the remainder when f (x) is divided by x+4?
Answers
The remainder when polynomial function is divide by linear function is 773.
Given that the polynomial functon f(x)=3x⁴+5 and the linear function is x+4.
As it is given that we have to find the remainder the polynomial
f(x)=3x⁴+5 is divided by the linear expression g(x)=x+4.
f(x)=3x⁴+5 .......(1)
g(x)=x+4 .......(2)
We know the remainder theorem that when a polynomial f(x) is divided by a linear expression (x−a), the remainder will be f(a).
From equation (2), we have a linear expression.
Now, on simplifying equation (2) to obtain the zero of g(x), we get
g(x)=x+4=0
x+4=0
Now, on comparing (x+4) and (x−a), we get
a=-4 ......(3)
Here, we have to get the value of f(a).
Now, using the remainder theorem, we can say that to get the remainder when the polynomial f(x)=3x⁴+5 is divided by g(x)=x+4, we have to replace x by -4 in the polynomial f(x)=3x⁴+5, we get
f(-4)=3(-4)⁴+5
f(-4)=3(256)+5
f(-4)=768+5
f(-4)=773
Therefore, the remainder when the polynomial f(x)=3x⁴+5 is divided by the linear expression g(x)=x+4 is 773.

It has no one moving in and an average of 175 people moving away every month. In about how many months will the populations of the towns be equal? Write an equation to model the situation. Then solve the equation and answer the question.
Answers
The populations of both towns would be equal in nine months.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Let's assume that both town's populations will be equal in x months.
After x months, the population of the first town is given by
200x - 75x + 57,900
The population of the second town after x months is given by
60,600 - 175x
In order for the population of both towns to be equal, we have
200x - 75x + 57,900 = 60,600 - 175x
This is the required equation that represents the given situation.
200x - 75x + 57,900 = 60,600 - 175x
Rearrange the likewise terms and apply arithmetic operation
200x - 75x + 175x = 60,600 - 57,900
300x = 2700
x = 2700/300
x = 9
