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

Answer:

4.06 = 4

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.

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:

a. positive.

Step-by-step explanation:

Matching and discordant pairs are used to describe the relationship between pairs of observations. To calculate matched and discordant pairs, data is treated as ordinal values. Therefore these are suitable for your application. The number of concordant and discordant pairs is used in Kendall's tau calculations, whose purpose is to determine the relationship among two ordinal variables.

If the direction of the classifications is the same, the pairs are concordant.

A pair of observations is discordant, suppose the subject being with an increased value on one variable is lower on the other.

SO; When discordant pairs exceed concordant pairs in a P-Q relationship, Kendall's tau reports a(n) positive association between the variables under study.

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:

i think the answer is 79

Step-by-step explanation:

im not really sure,

Answer:

We have a system of equations with no solutions.

One of the equations is:

x + y = 5.

Isolating y in one side of the equation, we get:

y = 5 - x

And the other equation has an y-intercept of -2, the equation can be written as:

y = a*x - 2.

Then the system will be:

y = -1*x + 5

y = a*x - 2

The solution of a system of equations is a point where the graphs of both functions intersect.

Then if both of these lines are parallel, the lines will never intersect, then the second equation must be parallel to the first one.

And two lines are parallel if they have the same slope.

Then the other equation will be:

y = -x - 2

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.

Answer:the answer is D y-2= 1/5(x+3)

Step-by-step explanation:I took the test

y-2=-1/5(x+3) is the  point-slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given two points are (-3, 2) and (2, 1)

m=1-2/2+3

=-1/5

So slope is -1/5.

Now let us find the point slope form

y-y₁=m(x-x₁)

y-2=-1/5(x+3)

Hence, y-2=-1/5(x+3) is the  point-slope form of the equation below that represents the line that passes through the points (-3, 2) and (2, 1).

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]

The probability is 24.609%

The mathematical subject of probability deals with the outcomes of random events. The term "probability" refers to the possibility or chance of an outcome. It clarifies the likelihood of a particular occurrence. We use phrases like "It will probably rain today," "he will probably pass the test," "there is very little chance of getting a storm tonight," and "most probably the price of onion will go high again" all the time.

Given a coin is tossed 9 times, and to find the probability of exact four heads,

the probability for condition given by  binomial probability ⁿCₓ[(p)ˣ(q)ⁿ⁻ˣ]

where p is probability of tail = 1/2 (favorable outcome)

q is probability of head = 1/2: (1 - p)

n = total outcome = 9

x = 4

ⁿCₓ[(p)ⁿ(q)ⁿ⁻ˣ] = ⁹C₄[(1/2)⁴(1/2)⁵]

= [tex]\frac{9!}{4!(9 - 4)!}[/tex] [1/16 x 1/32]

= [tex]\frac{9 x 8 x7 x 6 x 5!}{4! x 5!}[/tex](512)

126/512 = 0.24609

= 24.609%

Hence the probability, to the nearest thousandth is 24.609%.
