Step-by-step explanation:

The value of x is 13, then the measure of angle ∠B will be 121 degrees. Then the correct option is D.

What is an angle?

Angle is the space between the line or the surface that meets.  And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.

Linear angle - If the total of two angles is 180 degrees, they are said to be linear angles.

The angle ∠A and ∠B form a linear pair.

If ∠A = (6x – 19) and ∠B = (11x – 22).

Then we have

                  ∠A + ∠B = 180°

(6x – 19) + (11x – 22) = 180

                    17x – 41 = 180

                            17x = 221

                               x = 13

The value of x is 13, then the measure of angle ∠B will be

∠B = (11 × 13 – 22)

∠B = 143 – 22

∠B = 121

An apartment complex developer is considering building apartments in College Town, but first wants to do a market study. A sample was selected of monthly rent values ($) for 80 studio apartments in College Town with sample mean of 498.76. (Based on past experience, the developer assumes a known value of s = $65 for the population standard deviation.)
a. Develop a 98% confidence interval for the mean monthly rent for all studio apartments in this city.
b. Suppose the apartment developer wants a 98% confidence interval estimate of the population mean with a margin of error of E = $15. What sample size is needed?

Answers

Answer:

a. The 98% confidence interval for the mean monthly rent for all studio apartments in this city is between $481.85 and $515.67

b. A sample size of 102 is needed.

Step-by-step explanation:

Question a:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.98}{2} = 0.01[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.01 = 0.99[/tex], so Z = 2.327.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.327\frac{65}{\sqrt{80}} = 16.91[/tex]

The lower end of the interval is the sample mean subtracted by M. So it is 498.76 - 16.91 = $481.85

The upper end of the interval is the sample mean added to M. So it is 498.76 + 16.91 = $515.67

The 98% confidence interval for the mean monthly rent for all studio apartments in this city is between $481.85 and $515.67

Question b:

This is n for which M = 15. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]15 = 2.327\frac{65}{\sqrt{n}}[/tex]

[tex]15\sqrt{n} = 2.327*65[/tex]

[tex]\sqrt{n} = \frac{2.327*65}{15}[/tex]

[tex](\sqrt{n})^2 = (\frac{2.327*65}{15})^2[/tex]

[tex]n = 101.68[/tex]

Rounding up:

A sample size of 102 is needed.

No matter what direction the ball is thrown it always bounces off the arch once and strikes the same point on the ground. What is the distance between he person throwing the ball and the point on the ground at which the ball first strikes

Answers

Answer:

[tex]X=17.9m[/tex]

Step-by-step explanation:

Length of arc [tex]L_a=24m[/tex]

Height of arc [tex]H_a=8m[/tex]

Tet the length on the ground be

[tex]2a=24\\ a=12m[/tex]

Generally the Pythagoras equation is mathematically given by

[tex]a^2=b^2+c^2[/tex]

[tex]c^2=a^2+b^2[/tex]

[tex]c^2=12^2+8^2[/tex]

[tex]c^2=144^2+64^2[/tex]

[tex]c=8.9[/tex]

Answer:

Hamid will take 8 hours and 20 minutes to read 375 pages of the book.

Step-by-step explanation:

Given that Hamid has read 60 pages of the book he will be using for a book report, if he reads 45 pages per hour, to determine how many hours will it take him to read at least 375 pages of the book the following calculation must be done:

375/45 = X

8.3333 = X

0.333 x 60 = 20

Thus, Hamid will take 8 hours and 20 minutes to read 375 pages of the book.

7x²/2x + 6/
3х - 5/X +3

Answers

Option (E) 7x^2/(6x-10) is the reduced form of the rational expression is the correct answer.

What is a rational expression?

A rational expression is the ratio of two polynomials. It looks like fractions that have variables in their denominators. A rational expression is considered simplified if there are no common factors in its numerator and denominator.

For the given situation,

The rational expression is

7x²/(2x + 6) ÷ (3х - 5)/(x +3)

⇒ [tex]\frac{\frac{7x^{2} }{2x+6} }{\frac{3x-5}{x+3} }[/tex]

In conversion of division to multiplication, we need to change the division sign to multiplication sign and reciprocal the rational expression for simplification.

⇒ [tex](\frac{7x^{2} }{2x+6} )(\frac{x+3}{3x-5} )[/tex]

⇒ [tex](\frac{7x^{2} }{2(x+3)} )(\frac{x+3}{3x-5} )[/tex]

⇒ [tex](\frac{7x^{2} }{2(1)} )(\frac{1}{3x-5} )[/tex]

⇒ [tex]\frac{7x^{2} }{6x-10}[/tex]

Hence we can conclude that option (E) 7x^2/(6x-10) is the reduced form of the rational expression is the correct answer.

Answer:

Step-by-step explanation:

First we need to find theother 2 angles of the triangle.

We are given that the top angle is 60°

We know that the angles of a triangle add up to 180°

To find the bottom left angle of the triangle...

We can see that it is alternate exterior angles so they will equal.

To find the third angle of the triangle...

180 - 60 (given angle) -53 (alternate exterior angle) = 67°

Now we know that the bottom right angle inside the triangle is 67°.

To find x...

subtract 67 from 180 because the like is a combination of x and the 67° angle we just found. (a straight line angle = 180°)

180 - 67 = 113

The distance that an object falls when it is dropped is directly proportional to the
square of the amount of time since it was dropped. An object falls 288 feet in 3
seconds. Find the distance the object falls in 4 seconds

Answers

Answer:

After 4 seconds, the object will have fallen 512 feet.

Step-by-step explanation:

Given that the distance that an object falls when it is dropped is directly proportional to the square of the amount of time since it was dropped, to determine, if an object falls 288 feet in 3

seconds, the distance the object falls in 4 seconds, the following calculation must be performed:

288/3 ^ 2 = X

288/9 = X

32 = X

X / 4 ^ 2 = 32

X / 16 = 32

X = 32 x 16

X = 512

Thus, after 4 seconds, the object will have fallen 512 feet.

Answers

Answer: a 95% confidence interval for the proportion of all customers who have experienced a service interruption: (0.076, 0.127).

Step-by-step explanation:

Let p be the population proportion of all customers who have experienced a service interruption.

Confidence interval for p:[tex]\hat{p}\pm z^*\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex], where [tex]\hat{p}[/tex] = sample proportion, n= sample size, z* = critical z-value.

Given: n = 540

[tex]\hat{p}=\dfrac{55}{540}=0.102[/tex]

z* = 1.96

The required confidence interval:

[tex]0.102\pm (1.96)\sqrt{\dfrac{0.102(1-0.102)}{540}}\\\\=0.102\pm (1.96)(0.013024)\\\\=0.102\pm$$0.02552704\\\\=(0.102-$$0.02552704, 0.102+0.02552704)\\\\\approx(0.076, 0.127)[/tex]

Hence, a 95% confidence interval for the proportion of all customers who have experienced a service interruption: (0.076, 0.127).
