Answer:
9 · 2⁹
(-½, ½)
Step-by-step explanation:
The nth term of the original power series is 2ⁿ xⁿ.
Therefore, the nth term of the derived power series is:
d/dx (2ⁿ xⁿ) = n · 2ⁿ xⁿ⁻¹
When n=9, the term is 9 · 2⁹ x⁸.
Use ratio test:
lim(n→∞)│aₙ₊₁ / aₙ│
lim(n→∞)│((n+1) · 2ⁿ⁺¹ xⁿ) / (n · 2ⁿ xⁿ⁻¹)│
lim(n→∞)│(n+1) · 2x / n│
2│x│
The series converges when the limit is less than 1.
2│x│< 1
│x│< ½
-½ < x < ½
Check the endpoints.
If x = -½, the series is ∑ n · 2ⁿ (-½)ⁿ⁻¹ = ∑ -2n · (-1)ⁿ, which diverges.
If x = ½, the series is ∑ n · 2ⁿ (½)ⁿ⁻¹ = ∑ 2n, which diverges.
So the interval of convergence is (-½, ½).

Answer:
A. 27
B. 125
C. 857 [tex]\frac{3}{8}[/tex]
D. s³
Step-by-step explanation:
The volume of the cube = side × side × side = (side)³
Let us use this rule to complete the table
A.
∵ The side length of the cube = 3 units
∴ Its volume = 3 × 3 × 3 = 3³
∴ Its volume = 27 unit³
B.
∵ The side length of the cube = 5 units
∴ Its volume = 5 × 5 × 5 = 5³
∴ Its volume = 125 unit³
C.
∵ The side length of the cube = 9[tex]\frac{1}{2}[/tex] units
∴ Its volume = 9[tex]\frac{1}{2}[/tex] × 9[tex]\frac{1}{2}[/tex] × 9[tex]\frac{1}{2}[/tex] = (9[tex]\frac{1}{2}[/tex])³
∴ Its volume = 857 [tex]\frac{3}{8}[/tex] unit³

the histograms below summarize the average travel time to work for random samples of 70 workers in the los angeles area and 61 workers in thr new york city area.
a) briefly compare the distribution of travel times for these two regions
b) suppose you wanted to make the point that typical travel time is longer in the new york city area than in the los angeles area. which measure of center would you use? justify your answer
Answer:
A) There are more workers in the L.A area that take up to 20 minutes to get to their job.
B)40 minutes or more.
Step-by-step explanation:
Even though the graph from the New York area is more well distributed, you can see a clear increase in the number of cases above 40 minutes in the New York area compared to the Los Angeles, which are probable around 3o workes, while in the New York Area graph those travel times are reserved for more than half of the workers that were interviewed, so we can assure that workers from the New York Area spend more time traveling to their jobs.
A Christmas tree is supported by a wire that is 9 meters longer than the height of the tree. The wire is anchored at a point whose distance from the base of the tree is 41 meters shorter than the height of the tree. What is the height of the tree
Answer:
The height of the tree is 80 meters.
Step-by-step explanation:
Let the height of the Christmas tree be x meters.
Then the length of the wire will be, (x + 9) meters.
And the wire will (x - 41) meters away from the base of the tree.
Consider the diagram below.
Use Pythagoras theorem to solve for x as follows:
[tex]AB^{2}=AC^{2}+CB^{2}[/tex]
[tex](x+9)^{2}=x^{2}+(x-41)^{2}\\\\x^{2}+18x+81=x^{2}+x^{2}-82x+1681\\\\x^{2}-100x+1600=0\\\\x^{2} -80x-20x+1600=0\\\\x(x-80)-20(x-80)=0\\\\(x-80)(x-20)=0[/tex]
The value of x is either 80 or 20.
If x = 20, then the base CB will be -21. This is not possible as length is always positive.
Thus, the value of x is 80.
Hence, the height of the tree is 80 meters.
A major airline knows that about 2 percent of passengers do not manage to show up for their flight. Consider a small aircraft having 50 seats, and suppose that an airline sells precisely 50 tickets for a specific flight. Assuming that all passsengers are independent and have the same probability of not showing up, compute the probability that
Answer:
a. The probability that the aircraft is fully occupied = 0.3642
b. The probability that between 1 and 5 (including 1 and 5) passengers do not show up is = 0.6354
Step-by-step explanation:
From the given information:
We are to compute the probability that:
a. The aircraft is fully occupied( i.e. all the passengers show up)
b. Between 1 and 5 (including 1 and 5) passengers do not show up
Given that:
Percentage of passengers that do not show up = 2% = 0.02
And the population of the passengers = 50; since 50 tickets are being sold for a specific flight.
Let assume X be the random variable that follows a binomial distribution, thus, the number of passengers from the aircraft with 50 passengers can be represented as:
[tex]X \sim Bin (n = 50, p =0.02)[/tex]
Thus;
The probability that the aircraft is fully occupied i.e. all the passengers show up is:
[tex]= (1 - 0.02)^{50}[/tex]
= 0.98⁵⁰
= 0.3642
Hence, The probability that the aircraft is fully occupied = 0.3642
b. The probability that between 1 and 5 (including 1 and 5) passengers do not show up is:
= P(X = 1) + P(X =2) + P(X = 3) + P(X = 4) + P(X = 5)
= [tex]=(^{50}_1) 0.02(1-0.02)^{50-1} +(^{50}_2) 0.02(1-0.02)^{50-2} + (^{50}_3) 0.02(1-0.02)^{50-3} + ... + (^{50}_5) 0.02(1-0.02)^{50-5}[/tex]
[tex]=(^{50}_1) 0.02(0.98)^{49} +(^{50}_2) 0.02(0.98)^{48} + (^{50}_3) 0.02(0.98)^{47} + ... + (^{50}_5) 0.02(0.98)^{45}[/tex]
= 0.6354
Hence, The probability that between 1 and 5 (including 1 and 5) passengers do not show up is = 0.6354

Rise/Run(2/4)
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 1) and (x₂, y₂ ) = (2, 0) ← 2 points on the line
m = [tex]\frac{0+1}{2-0}[/tex] = [tex]\frac{1}{2}[/tex]

Greeks bucked a global trend in which people in most countries expect their lives in five years to be better than their current lives. Even among those countries with much lower currrent life ratings, greater optimism was found because people cannot fathom their lives getting worse. But in Greece, only 25% expect their lives to be better in five years. In a simple random sample of 1100 Greek citizens, what is the probability that less than 27 percent of the sample expect their lives to be better in five years?
Answer:
The value is [tex]P( p < 0.27 ) = 0.67792[/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is p= 0.25
The sample size is n = 100
Generally given that the sample size is sufficiently large n > 30 , the mean of this sampling distribution is mathematically represented as
[tex]\mu_{x} = p = 0.25[/tex]
Generally the standard deviation is mathematically represented as
[tex]\sigma = \sqrt{ \frac{ p(1 - p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{ \frac{ 0.25 (1 - 0.25 )}{100} }[/tex]
=> [tex]\sigma = 0.0433[/tex]
Generally the probability that less than 27 percent (0.27)of the sample expect their lives to be better in five year is mathematically represented as
[tex]P( p < 0.27 ) = P( \frac{ p - \mu_{x}}{\sigma} < \frac{0.27 - 0.25 }{ 0.0433} )[/tex]
[tex]\frac{p -\mu}{\sigma } = Z (The \ standardized \ value\ of \ p )[/tex]
=> [tex]P( p < 0.27 ) = P( Z< 0.4619 )[/tex]
From the z table the area under the normal curve to the left corresponding to 0.4619 is
[tex]P( Z< 0.4619 ) = 0.67792[/tex]
[tex]P( p < 0.27 ) = 0.67792[/tex]
