What value goes in cell B?
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
D.
∵ The side length of the cube = s units
∴ Its volume = s × s × s = s³
∴ Its volume = s³ unit³

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.

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).
solve for p in 5p + 3r = q
Answer:
p = -(3 r)/5 + q/5
Step-by-step explanation:
Solve for p:
3 r + 5 p = q
Hint: | Isolate terms with p to the left hand side.
Subtract 3 r from both sides:
5 p = -3 r + q
Hint: | Solve for p.
Divide both sides by 5:
Answer: p = -(3 r)/5 + q/5

Which of the following sets of numbers could represent the three sides of a right triangle?(check image)answer quick
Answer:
{33, 56, 65}
Step-by-step explanation:
Since, Hypotenuse of a right triangle is the longest side of the right triangle,
By Pythagoras theorem,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
Therefore, to prove the numbers representing the sides of a right triangle we will prove,
(largest number)² = (number 1)² + (number 2)²
Option (1)
{17, 30, 34}
34² = 17² + 30²
1156 = 289 + 900
1156 = 1189
But it's not true.
Therefore, these numbers doesn't represent the sides of a right triangle.
Option (2)
{11, 59, 61}
61² = 11² + 59²
3721 = 121 + 3481
3721 = 3602
Not true.
Therefore, these numbers doesn't represent the sides of a right triangle.
Option (3)
{33, 56, 65}
65² = 56² + 33²
4225 = 3136 + 1089
4225 = 4225
True
Therefore, these numbers represents the sides of a right triangle.
Option (4).
{20, 21, 30}
30² = 20² + 21²
900 = 400 + 441
900 = 841
Not True.
Therefore, these numbers doesn't represent the sides of a right triangle.

Answer: 2/4
Step-by-step explanation:
Rise=2
Run=4
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]

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.
