Answer 1

The triangles 1, 2, 4, 7 and 8 are right triangles by Pythagorean relationship.

How to determine if a triangle is a right triangle

Triangles are closed figures formed by three line segments, a right triangle is a triangle with one right angle. Right triangles have a long side known as hypotenuse (r) and two shorter sides known as legs (x, y), whose Pythagorean relationship is shown below:

r = √(x² + y²)

Now we proceed to check whether each triangle is a right triangle or not:

Case 1:

D = √(8² + 6²)

D = 10 (YES)

Case 2:

D = √(5² + 12²)

D = 13 (YES)

Case 3:

D = √(12² + 9²)

D = 15 (NO)

Case 4:

D = √(8² + 15²)

D = 17 (YES)

Case 5:

D = √(4² + 9²)

D ≈ 9.849 (NO)

Case 6:

D = √(14² + 5²)

D ≈ 14.866 (NO)

Case 7:

D = √(20² + 15²)

D = 25 (YES)

Case 8:

D = √(24² + 10²)

D = 26 (YES)

Answer:

113

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

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.

Step-by-step explanation:

An Internet service provider sampled 540 customers and found that 55 of them experienced an interruption in their service during the previous month. Construct a 95% confidence interval for the proportion of all customers who have experienced a service interruption. (0.080, 0.123) (0.873, 0.924) (0.076, 0.127) (0.102, 0.898)

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).

Given:

To find:

The quotient by using the synthetic division.

Solution:

We have,

[tex](2x^3+4x^2-35x+15)\div (x-3)[/tex]

Here,

Dividend = [tex](2x^3+4x^2-35x+15)[/tex]

Divisor = [tex]x-3[/tex]

The coefficient of dividend are [tex]2, 4, -35, 15[/tex]. Write the coefficients of the dividend on the top row and we need to use 3 as divisor for synthetic division. The synthetic division is show below:

[tex]3 | 2\quad \quad 4\quad \quad -35\quad \quad 15\\\quad{}\quad{} \quad \quad \ 6\quad \quad \ \ \ 30\quad -15\\\overline{\quad 2\quad \quad 10\quad \quad -5\quad \quad 0\ \ \ }[/tex]

The bottom row represents the coefficients of quotient but the last element of bottom row is the remainder.

Degree of dividend is 3 and degree of division is 1. So, the degree of quotient must be [tex]3-1=2[/tex].

The quotient is [tex]2x^2+10x-5[/tex] and the reminder is 0.

Therefore, the correct option is D.

Step-by-step explanation:

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]

A sample size of 102 is needed.

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

2)y = -3x - 6
3)y = -3x + 10
4) y = -3x + 14

Answers

Answer:

1) y = -3x + 6  

Step-by-step explanation:

1) First, write the equation of the line in point-slope form with the given information. Use the point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] and substitute values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].  

Since [tex]m[/tex] represents the slope, substitute -3 in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of the point the line intersects, substitute the x and y values of (4,-6) into the formula as well. This gives the following equation:

[tex]y+6 = -3(x-4)[/tex]

2) Now, isolate the y in the equation to put it in slope-intercept form and find the answer.

[tex]y + 6 = -3(x-4)\\y + 6 = -3x+12\\y = -3x+6[/tex]

WHAT IS THE WORD CHOICE FOR THE FOLLOWING PARAGRAPHING__________________________________________________________________In 1752, Benjamin Franklin had a theory that lightning was electricity. He wanted to prove that the power could be transferred to other objects. He grabbed a kite and experimented on a stormy afternoon.Franklin believed that thunder clouds contained electrical charges. His plan was to fly the kite into the clouds so that electricity passed down the wet kite string. With his son, William, as his assistant, he went to work.First, he tied an iron key to the silk kite string. Next, he ran a metal wire from the key into a jar designed to store electrical charges. Once the kite was in the air, he stood in a barn to keep safe and dry.Soon, electrical charges from the clouds passed into the kite.
