Answer:

The distance between given points is: √20

Step-by-step explanation:

The given numbers are complex numbers. In order to find the distance between two numbers in complex plain, their difference is taken and then modulus is applied.

Given numbers are:

[tex]z_1 = 2-3i\\z_2 =4+i[/tex]

The difference will be calculated as:

[tex]z_2-z_1 = (4+i)-(2-3i)\\= 4+i-2+3i\\=2+4i[/tex]

The distance will be:

[tex]d = \sqrt{(2)^2+(4)^2}\\= \sqrt{4+16}\\=\sqrt{20}[/tex]

Hence,

The distance between given points is: √20

Answer:

Maria sold 56.5% of the total quantity of tickets sold.

Step-by-step explanation:

Given that between Maria and Sarah they both sold 161 tickets (91 + 70), and that of those 161 Maria sold 91 while Sarah sold 70, to determine the percentage of tickets that Maria sold over the total amount, the following crossed multiplication must be performed:

161 = 100

91 = X

((91 x 100) / 161) = X

9,100 / 161 = X

56.5 = X

Therefore, Maria sold 56.5% of the tickets sold.

Complete Question

A random sample of 300 circuits generated 13 defectives. a. Use the data to test

                            [tex]H_o : p = 0.05[/tex]

Versus

                          [tex]H_1 : p \ne 0.05[/tex]

Use α = 0.05. Find the P-value for the test

Answer:

The  p-value is  [tex]p-value = 0.5949[/tex]        

Step-by-step explanation:

From the question we are told that

  The sample size is  n = 300

    The number of defective circuits is  k = 13

Generally the sample proportion of defective circuits is mathematically represented as

        [tex]\^ p = \frac{k}{n}[/tex]

=>     [tex]\^ p = \frac{13}{300}[/tex]

=>     [tex]\^ p = 0.0433[/tex]

Generally the standard Error is mathematically represented as

       [tex]SE = \sqrt{\frac{p(1- p)}{n} }[/tex]

=>     [tex]SE = \sqrt{\frac{0.05(1- 0.05)}{300} }[/tex]

=>     [tex]SE = 0.0126[/tex]

Generally the test statistics is mathematically represented as

       [tex]z = \frac{\^ p - p }{SE}[/tex]

=>     [tex]z = \frac{0.0433 - 0.05 }{0.0126}[/tex]

=>     [tex]z = -0.5317[/tex]

From the z table  the area under the normal curve to the left  corresponding to  -0.5317  is

         [tex](P < -0.5317 ) = 0.29747[/tex]

Generally the p-value is mathematically represented as

       [tex]p-value = 2 * P(Z < -0.5317 )[/tex]

=>     [tex]p-value = 2 * 0.29747[/tex]

=>     [tex]p-value = 0.5949[/tex]        

Answer:

Turkey is more popular.

Step-by-step explanation:

If in the survey about which is the favorite food on Thanksgiving, 9% answered turkey and 7/100 answered marshed potatoes, the most popular food among both is turkey.

This is so because in the case of marshed potatoes, the fact that 7 out of 100 choose this food implies that 7% of those surveyed designate it as their favorite, which is less than the 9% who choose turkey as such.

Answer: x = 3

Step-by-step explanation:

if two triangles are congruent, that means thy have the same sides and angles.

6x + 8 = 9x - 1

-6x +1.    -6x +1

9 = 3x

divide both sides by 3 to get x by itself

x = 3

Answer:

64 people

Step-by-step explanation:

in the morning, 4 people are called. Those 4 people call 4 more people, which brings it to 16 people called. Those 16 people then each call 4 others, which is 16 x 4. Giving you the answer of 64 people for the evening.

FYI, if the question asked how many people were called in total, you would add the 4 people from the morning, 16 people from the afternoon, and 64 people in the evening to get a total of 84 people called.

Answer:

Step-by-step explanation:

Answer:

68≥25+3x

x≥15

Step-by-step explanation:

the overall goal is to have $68, so the goal needs to be less then or equal to the weekly $25 plus each additional subscription at $3 (x represents the needed amount of subscriptions he sells) the inequality would look something like 68≥25+3x because he wants the money this week.

to solve the inequality you would subtract the 25 from the 68, leaving you with 43≥3x as the new inequality, now you need to divide both sides by 3. Which comes out to 14.33333..... since we cant sell a fraction of a subscription you must round up giving you the new inequality of x≥15

this means that in order for Andre to get the cleats this week, he must sell at least 15 subscriptions

hope this helped

a.)   25x + 3y ≥ 68

b.) x = 1, y = 43

c.) As x increases, y decreases

A linear inequality is a mathematical relation which gives the range of values a variable or a function can take.

Given,

Wage per week= $25

Subscription earning = $3

Let x and y be the number of weeks and number of subscriptions.

Therefore, 25x + 3y ≥ 68

Hence, 25x + 3y ≥ 68 is the required inequality.

Let x = 1

Therefore  minimum value of y = 43.

2: -2/3

3: 1

4: -3/2

5: -1/4

6: -4

7: 4

8: 1/4

9: 2/3

10: no slope

Step-by-step explanation:

The Taylor series expansion is:

Tₙ(x) = ∑ f⁽ⁿ⁾(a) (x − a)ⁿ / n!

f(x) = 1/x, a = 4, and n = 3.

First, find the derivatives.

f⁽⁰⁾(4) = 1/4

f⁽¹⁾(4) = -1/(4)² = -1/16

f⁽²⁾(4) = 2/(4)³ = 1/32

f⁽³⁾(4) = -6/(4)⁴ = -3/128

Therefore:

T₃(x) = 1/4 (x − 4)⁰ / 0! − 1/16 (x − 4)¹ / 1! + 1/32 (x − 4)² / 2! − 3/128 (x − 4)³ / 3!

T₃(x) = 1/4 − 1/16 (x − 4) + 1/64 (x − 4)² − 1/256 (x − 4)³

f(x) = 1/x has a vertical asymptote at x=0 and a horizontal asymptote at y=0.  So we can eliminate the top left option.  That leaves the other three options, where f(x) is the blue line.

Now we have to determine which green line is T₃(x).  The simplest way is to notice that f(x) and T₃(x) intersect at x=4 (which makes sense, since T₃(x) is the Taylor series centered at x=4).

The bottom right graph is the only correct option.

Answer:

0.85 of the original piece of lumber remains.

Step-by-step explanation:

Well, this lumber piece of lumber started as 2.5 meters long. Then, a 1.65 meter piece was cut off of it. All we need to do is subtract.

2.5 - 1.65 =

2.50 - 1.65 = 0.85.

Therefore, 0.85 of the original piece of lumber remains.

Answer:

The value of x = 10.

Step-by-step explanation:

From the given triangle,

We know that the sum of a triangle is 180°.

i.e.

K + L + M = 180°

(5x - 18)° + 90° + (3x + 28)° = 180°

[tex]5x-18+90+3x+28=180[/tex]

[tex]5x+3x-18+90+28=180[/tex]

[tex]8x-18+90+28=180[/tex]

[tex]8x+100=180[/tex]

[tex]8x=80[/tex]

[tex]\frac{8x}{8}=\frac{80}{8}[/tex]

[tex]x=10[/tex]

Therefore, the value of x = 10
