Answers

Answer 1

Observe that the [tex]n[/tex]-th term in the sum is

[tex]\dfrac{n^2 + n(n+1) + (n+1)^2}{n^3(n+1)^3} = \dfrac{3n^2 + 3n + 1}{n^3 (n+1)^3} \\\\ ~~~~~~~~ = \dfrac{(n+1)^3 - n^3}{n^3(n+1)^3} \\\\ ~~~~~~~~ = \dfrac1{n^3} - \dfrac1{(n+1)^3}[/tex]

Then the sum telescopes, and we have

[tex]\displaystyle \sum_{n=1}^{9} \frac{n^2 + n(n+1) + (n+1)^2}{n^3 (n+1)^3} = \sum_{n=1}^{9} \left(\frac1{n^3} - \frac1{(n+1)^3}\right) \\\\ ~~~~~~~~ = \left(\frac1{1^3} - \frac1{2^3}\right) + \left(\frac1{2^3} - \frac1{3^3}\right) + \cdots + \left(\frac1{8^3} - \frac1{9^3}\right) + \left(\frac1{9^3} - \frac1{10^3}\right) \\\\ ~~~~~~~~ = \frac1{1^3} - \frac1{10^3} \\\\ ~~~~~~~~ = 1 - \frac1{1000} = \boxed{\frac{999}{1000}}[/tex]

Answer 2

The sum of the series is 999/1000 .

What is a Series ?

A series is a sequence of expression in a certain pattern.

The series of n terms is given

[tex]\rm \frac{1^2+1*2+2^2}{1^3*2^3} + \frac{2^2+2*3+3^2}{2^3*3^3} +...+\frac{9^2+9*10*10^2}{9^3*10^3}[/tex]

nth term of the series is given by

[tex]\rm T_n = \rm \dfrac{n^2 + n(n+1)+ (n+1)^2}{n^3*(n+1)^3}[/tex]

On simplification it can be written as

[tex]\rm T_n = \rm \dfrac{3n^2 + 3n+1}{n^3*(n+1)^3}\\\\T_n = \rm \dfrac{3n(n +1)+1}{n^3*(n+1)^3}\\\\\\T_n = \rm \dfrac{ (n +1)^3 - n^3}{n^3*(n+1)^3}\\\\T_n = \rm \dfrac{ 1}{n^3} - \dfrac{1}{(n+1)^3}[/tex]

The sum of terms from 1 to 9 is given by

∑ ( [tex]\rm \frac{ 1}{n^3} - \frac{1}{(n+1)^3}[/tex])

= [tex]\rm \dfrac{1}{1^3} - \dfrac{1}{2^3} + \dfrac{1}{2^3} - \dfrac{1}{3^3}+ .......... + \dfrac{1}{9^3} - \dfrac{1}{10^3}[/tex]

= (1/1³) - (1/10³)

= 999/1000

Therefore the sum of the series given is 999/1000

Then reflect the result over the y-axis.
What are the coordinates of the final point?

Answers

Answer:

Step-by-step explanation:

Answer

When you translate either left or right, the x coordinate is the one that you change. To go right when you are dealing with a point, you must add the amount you are asked to go right. So when you go right 3 units, add 3 to the 5.

(5 + 3,1) = (8,1)

Calculate the price per roll for each shop.
Write which shop is the best value for money in the comment box.

Answers

The price per roll for Lidal and Oldi shop is 0.35 and 0.36 respectively.

Therefore Lidal shop is the best value for money.

Given,

Lidal shop:

8 rolls costs 2.80

∴ one roll costs = 2.80/8

= 0.35

Oldi shop:

9 rolls costs 3.24

∴ one roll costs = 3.24/9

= 0.36

Hence we get the per price for the shops as 0.35 and 0.36

we can see that for lidal shop if per roll it is 0.35 then if a person wants to buy 9 rolls then it will cost him 3.15, whereas in the case of oldi shop the price for 9 rolls is 3.24.Therefore, lidal shop is the best value for money.

Using the z-distribution, the 95% confidence interval for the population proportion is (0.5791, 0.7133).

What is a confidence interval of proportions?

A confidence interval of proportions is given by:

In which:

[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.

In this problem, we have a 95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so the critical value is z = 1.96.

The other parameters are given as follows:

[tex]n = 195, \overline{p} = \frac{126}{195} = 0.6462[/tex]

Hence the bounds of the interval are:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6462 - 1.96\sqrt{\frac{0.6462(0.3538)}{195}} = 0.5791[/tex]

[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.6462 + 1.96\sqrt{\frac{0.6462(0.3538)}{195}} = 0.7133[/tex]

100 POINTS!! Find the indicated angle or side. Give an exact answer.
Find the measure of angle A in degrees.

Answers

Answer:

A = 120

Step-by-step explanation:

To find angle A we will need to use the law of cosines, since we know the three sides of the triangle.

a^2=b^2+c^2−2*b*c*cosA

(2 sqrt(13)) ^2 = 6^2 + 2^2 + 2 * 6 * 2 cos A

4*13 = 36 + 4 - 24 cos A

52 = 40- 24 cos A

12 = -24 cos A

-1/2 = cos A

Take the inverse cos of each side

cos^-1(-1/2) = cos^-1(cos A)

120 = Cos A or 240 = Cos A

A cannot be greater than 180 so A = 120

Answer:

A = 120°

Step-by-step explanation:

We can use the cosine rule to solve for angle A, since lengths of all sides are known:

[tex]a^2 = b^2+ c^2 - 2(b)(c) \space\ cos A[/tex]

where a, b, and c are the sides opposites angles A, B, and C respectively.

∴ a = 2√3 , b = 6, c = 2

• Rearranging the formula to make A the subject:

[tex]2(b)(c) \space\ cos A = b^2 + c^2 -a^2[/tex]

⇒ [tex]cos A = \frac{b^2 + c^2 -a^2}{2(b)(c)}[/tex]

⇒ [tex]A = cos^{-1}(\frac{b^2 + c^2 -a^2}{2(b)(c)} )[/tex]

• Now we can substitute the values into the equation to calculate the value of angle A:

[tex]A = cos^{-1}(\frac{6^2 + 2^2 -(2\sqrt{13})^2}{2(6)(2)} )[/tex]

⇒ [tex]A = cos^{-1} (-\frac{1}{2} )[/tex]

⇒ A = 120°

In order for the parallelogram to be a rhombus, x=[?]. (9x+31) 32
HELP NEEDED ASAP

Answers

X = 3

Explanation:

In a rhombus, the diagonals are perpendicular, creating four congruent right triangles.

Because the value of all three angles within any given triangle will add up to 180°, we can easily simplify the equation.

First, we’ll need to add our given angles. Which are 32° (as can be seen on the graph) and 90° (because any pair of perpendicular lines create four right angles and this triangle includes one of them).

32° + 90° = 122°

Next, we’ll subtract 122 from 180 to find the remaining angle measure

180 - 122 = 58

Then, we’ll subtract 31 with the subtraction property of equality

58 - 31 = 27

Right now, our equation looks like:

27 = 9x

In order to simplify this equation further, we must use the division property of equality to get x on its own.

27/9 = 9x/9

b - II) The selling price of a videogame was of $800.

c) He received $15,200 from the sale of the videogames.

What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Item a:

He has 3/5 of 40 videogames left, hence:

3/5 x 40 = 3 x 8 = 24.

He has 24 videogames left.

Item b:

He kept 5/8 of the 24 videogames, hence:

5/8 x 24 = 5 x 3 = 15.

He kept 15 videogames for himself.

He also sold 9 videogames for $7,200, hence the selling price of one of them is:

7200/9 = $800.

Item c:
