Find all values of x for which the series converges. (Enter your answer using interval notation.) [infinity] 9 x − 7 9 n n = 0 For these values of x, write the sum of the series as a function of x.
Answer:
The series converges to [tex]$ \frac{1}{1-9x} $[/tex] for [tex]$ \frac{-1}{9} < x < \frac{1}{9} $[/tex]
Step-by-step explanation:
Given the series is [tex]$ \sum_{n=0}^{\infty} 9^n x^n $[/tex]
We have to find the values of x for which the series converges.
We know,
[tex]$ \sum_{n=0}^{\infty} ar^{n-1} $[/tex] converges to (a) / (1-r) if r < 1
Otherwise the series will diverge.
Here, [tex]$ \sum_{n=0}^{\infty} 9^n x^n = \sum_{n=0}^{\infty} (9x)^{n} $[/tex] is a geometric series with |r| = | 9x |
And it converges for |9x| < 1
Hence, the given series gets converge for [tex]$ \frac{-1}{9} < x < \frac{1}{9} $[/tex]
And geometric series converges to [tex]$ \frac{a}{1-r} $[/tex]
Here, a = 1 and r = 9x
Therefore, [tex]$ \frac{a}{1-r} = \frac{1}{1-9x} $[/tex]
Hence, the given series converges to [tex]$ \frac{1}{1-9x} $[/tex] for [tex]$ \frac{-1}{9} < x < \frac{1}{9} $[/tex]

An bus station has determined that the relationship between the number of passengers on a bus and the total weight of luggage stored in the baggage compartment can be estimated by the least squares regression equation y=118+14x. Predict the weight of luggage for a flight with 142 passengers.
Answer:
The weight of luggage for a flight with 142 passengers is 2,106
Step-by-step explanation:
The total weight of luggage stored in the baggage compartment can be estimated by the least squares regression equation:
y=118+14*x
where y is the total weight of luggage stored in the luggage compartment and x is the number of passengers on a bus.
If you want to predict the weight of luggage for a flight with 142 passengers, this means that x must have a value of 142. So, replacing in the expression:
y=118+14*142
you get:
y=118+1,988
y=2,106
The weight of luggage for a flight with 142 passengers is 2,106

Length = 20 metres
Width = 10 mteres
Step-by-step explanation:
Let the width be x metres
Let the length be 2x metres
Perimeter = 60 metres
therefore, by the problem ,
2(length+breadth)= perimeter
=>2(2x+x)=60
=>2 *3x=60
=>6x=60
=>x=10
length = 20 metres
width = 10 mteres

On the graph of the equation 3x+ 2y=18, what is the value of the y-intercept?
A) -9
B) -6
C) 6
D) 9
Answer:
D) 9Step-by-step explanation:
[tex]3x+ 2y=18\\\\Let \:x\:equal\:to\:0\\\\3(0)+2y=18\\\\0+2y=18\\\\2y=18\\\\Divide \:both\:sides\:of\:the\:equation\:by \:2\\\frac{2y}{2} =\frac{18}{2} \\\\y =9\\(0,9)[/tex]
Answer:
y = 9
Step-by-step explanation:
3x + 2y = 18
required:
find the y-intercept
we have to eliminate x to get the y intercept value
3(0) + 2y = 18
2y = 18
y = 18/2
y = 9
so the x & y intercept would be (0, 9)
A teacher records the amount of time it took a random sample of students to finish a test and their scores on that test. Let x be the score and y be the amount of time. Conduct a hypothesis test of the claim that there is a linear correlation between the variables, using a 0.10 level of significance. Find the PERCENTAGE OF THE VARIANCE IN THE Y-VALUES THAT CAN BE EXPLAINED BY THEIR LINEAR RELATIONSHIP WITH THE X-VALUES.
Answer:
The question is incomplete. The complete table is:
Score in percent (X): 80, 75, 70, 90, 95, 100, 75, 60, 75, 95
Time in minute (Y) : 45, 48, 40, 50, 40, 30, 30, 39, 38, 55
The answer is 0.55 %
Step-by-step explanation:
ΣX = 815
ΣY = 425
ΣX x Y = 34565
Σ = 67925
Σ[tex]$Y^2$[/tex] = 18699
So, correlation coefficient, b
[tex]$b= \frac{n \Sigma XY- \Sigma X \Sigma Y}{\sqrt{n \Sigma X^2-( \Sigma X)^2} \times \sqrt{(n \Sigma Y^2 -(\Sigma Y)^2}}$[/tex]
[tex]$b = \frac{(10 \times 34565)-(815 \times 425)}{\sqrt{(10 \times 67925)-(815)^2} \times \sqrt{(10 \times 10699)-(425)^2}}$[/tex]
[tex]$b= -\frac{725}{9779 \times 2702}$[/tex]
b = -0.0741
Correlation Determination:
[tex]$B^2 = (-0.0741)^2$[/tex]
= = 0.0055 = 0.55%
Therefore, 0.55 percentage of the variation in y can be explained by x variable.

c. there is 90% confidence that the proportion of the adult citizens of the nation that dreaded Valentine's Day is between 0.196 and 0.304.
d. there is 90% confidence that 25% of the adult citizens of the nation dreaded Valentines Day.
Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The sample size is [tex]n = 2500[/tex]
The sample proportion is [tex]\r p = 0.21[/tex]
The margin of error is [tex]E = 0.054[/tex]
The 90% confidence interval is mathematically represented
[tex]\r p - E < p < \r p + E[/tex]
=> [tex]0.21 - 0.054 < p < 0.21 + 0.054[/tex]

40% of the cost was tax. if the taxes paid were $15,000, what was the total cost of the car?
Answer:
$37500
Step-by-step explanation:
For this we can simply create a proportion of the percentages.
.4 / 1 == 15000 / x
Now we solve for x:
x = 15000/.4
x = 37500
Thus, the cost of the car was $37,500.

A researcher examines the records of all registered voters in one city and finds that 43% are registered democrats. Is the evaluated group a population or a sample?
Answer: Population
Step-by-step explanation: Population is refers to the whole or entire members or of a given set. This is different from a sample which is used to refer to members of a subset (a subset is a certain portion or fraction of an entire set). In the scenario above, since the evaluation was based on the entire number of registered voters in the country, this means we are referring to a population. The inference about the percentage of democratic voters was drawn from a pool of all the entire number of registered voters available in the country and not from a certain subset or portion of registered voters. Hence, the evaluated group is a population.

In a certain year, 23% of all teenagers in the United States had checking accounts. Your bank, TeenChex Inc., is interested in targeting teenagers who do not already have a checking account. (a) If TeenChex selects a random sample of 1,000 teenagers, what number of teenagers without checking accounts can it expect to find? teenagers What is the standard deviation σ of this number? (Round the standard deviation to one decimal place.)
Answer:
1. 770
2. 13.31
Step-by-step explanation:
n = 1000
P (probability of those with account) = 23% = 0.23
q(probability of those without account) = 1-p = 0.77
a. We are expected to find the expected number of those without checking account
= n * q
= 1000 * 0.77
= 770
b. Standard deviation
= √n*p*t
= √1000x0.77x0.23
= √177.1
= 13.31

Find the prime factorization of the composite number.
795
795 =
(Type your answer using exponential notation.)
Answer:
3×5×53
Step-by-step explanation:
You can use divisibility rules to find the small prime factors.
The number ends in 5, so is divisible by 5.
795/5 = 159
The sum of digits is 1+5+9 = 15; 1+5 = 6, a number divisible by 3, so 3 is a factor.
159/3 = 53 . . . . . a prime number,* so we're done.
795 = 3×5×53
_____
* If this were not prime, it would be divisible by a prime less than its square root. √53 ≈ 7.3. We know it is not divisible by 2, 3, or 5. We also know the closest multiples of 7 are 49 and 56, so it is not divisible by 7. Hence 53 is prime.
