Find the slope of the line that passes through the points (6.-6) and (11,-4)

First let's start with A

All the sides in a hexagon add up to 720

do 720/6

720/6=120

A=120

Each angle in that hexagon adds up to 120

Then B

The triangle is equilateral, so 180/3=60

B would be 60

C would also be 60

D is = to a, so D=120

A:120

B:60

C:60

D:120

Answer:

r = 1

Step-by-step explanation:

(6, -3) ; (14, r)

Slope = \(\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\)

\(\frac{r-[-3]}{14-6}=\frac{1}{2}\\\\\frac{r + 3 }{8} = \frac{1}{2}\\\)

Cross multiply,

(r + 3)*2 = 1*8

2r + 6  = 8             {Subtract 6 from both sides }

       2r = 8 - 6

       2r = 2          {divide both sides by 2}

        r = 2/2

r = 1

The height of the skyscraper is D. 156.26 ft

To determine the height of the skyscraper,  we need to consider the following trigonometric identities listed thus;

From the information given, we have that;

Angle, θ = 38 degrees

The shadow casted is the adjacent side of the angle and is 200 ft

The height off the skyscraper is the opposite side

Now, using the tangent identity, we have that;

tan θ = opposite/adjacent

tan 38 = h/200

cross multiply the values, we get;

h = 200(0.7812)

Multiply the values

h = 156. 26 ft

a) An equation for the given problem is;

b) The initial value for the given problem is;

c) The number of hours that a member rented the tennis ball machine if the total cost was $130 is; 4 hours

The general formula for the equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

a) Base price for joining the fitness center is $50 and as such this can be said to be the y-intercept. Then, the tennis ball machine is rented for $10 per hour.

Now, the number of hours the machine is rented (x) and the total cost (y), then the equation is;

y = 10x + 50

b) The initial value is the price when x = 0 which is the y-intercept and as such it is $50.

c) The cost for renting the tennis ball machine for 2 hours is;

y = 10(2) + 50

y = $70

The cost for renting the tennis ball machine for 5 hours is;

y = 10(5) + 50

y = $120

The cost for renting the tennis ball machine for 0 hours is;

y = 10(0) + 50

y = $50

d) If total cost is $130, then we have;

130 = 10x + 50

10x = 80

Following are the responses to the given question:

Step-by-step explanation:

Please find the table in the attached file.

mean and standard deviation difference: \(\bar{d}=\frac{\Sigma d}{n} =\frac{-4-6-.......-4-4}{8}=-4.125 \\\\S_d=\sqrt{\frac{\Sigma (d-\bar{d})^2 }{n-1}}=\sqrt{\frac{(-4 + 4.125)^2 +.......+(-4 +4.125)^2 }{8-1}}= 1.246\)

For point a:

hypotheses are:

\(H_0 : \mu_d \geq -3\\\\H_a : \mu_d < -3\\\\\)

degree of freedom:

\(df=n-1=8-1=7\)

 From t table, at\(\alpha = 0.05\), reject null hypothesis if \(t <-1.895\).

test statistic:  

\(t=\frac{\bar{d}-\mu_d }{\frac{s_d}{\sqrt{d}}}=\frac{ -4.125- (-3)}{\frac{1.246}{ \sqrt{8}}} =-2.55\)

because the \(t=-2.553 <-1.895\), removing the null assumption. Data promotes a food product manufacturer's assertion with a likelihood of Type 1 error of 0.05.

For point b:

From t table, at \(\alpha =0.01\), removing the null hypothesis if \(t<-2.998\).

because \(t=-2.553 >-2.908\), fail to removing the null hypothesis.  

The data do not help the foodstuff producer's point with the likelihood of a .01-type mistake.

For point c:

Hypotheses are:

\(H_0: \mu_d \geq -5\\\\H_a: \mu_d < -5\)

Degree of freedom:

\(df=n-1=8-1=7\)

From t table, at \(\alpha =0.05\), removing the null hypothesis if \(t <-1.895\).

test statistic:  \(t=\frac{\bar{d}-\mu_d}{\frac{s_d}{\sqrt{n}}} =\frac{-4.125-(-5)}{\frac{1.246}{\sqrt{8}}}=1.986\)

Since \(t-1.986 >-1.895\), The null hypothesis fails to reject. The results do not support the packaged food producer's claim with a Type 1 error probability of 0,05.

From t table, at\(\alpha= 0.01\), reject null hypothesis if\(t<-2.998\).

Since \(t=1.986>-2.998\) , fail to reject null hypothesis.  

Data do not support the claim of the producer of the dietary product with the probability of Type 1 error of .01.

Answer:

x = 136

Step-by-step explanation:

This one is quite simple

The shape formed inside of the circle is a quadrilateral.

when a quadrilateral is formed inside of a circle opposite angles of the quadrilateral will add up to 180

we are given x's opposite angle so we can find x by subtracting the given angle's measure (44) from 180

so x = 180 - 44

180 - 44 = 136

hence, x = 136

Answer:

1. 0.1684 = 16.84%.

2. 0.2568 = 25.68%

3. 0.0013 = 0.13%

4. 0.0126 = 1.26%.

Step-by-step explanation:

For each person, there are only two possible outcomes. Either they have blood that is Group O, or they do not. The probability of a person having blood that is Group O is independent of any other person, which means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

45% of them have blood that is Group O

This means that \(p = 0.45\)

Question 1:

This is P(X = 6) when n = 16. So

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 6) = C_{16,6}.(0.45)^{6}.(0.55)^{10} = 0.1684\)

So 0.1684 = 16.84%.

Question 2:

This is P(X = 3) when n = 8. So

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 3) = C_{8,3}.(0.45)^{3}.(0.55)^{5} = 0.2568\)

So 0.2568 = 25.68%.

Question 3:

This is P(X = 16) when n = 20. So

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 16) = C_{20,16}.(0.45)^{16}.(0.55)^{4} = 0.0013\)

So 0.0013 = 0.13%.

Question 4:

This is P(X = 9) when n = 11. So

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 9) = C_{11,9}.(0.45)^{9}.(0.55)^{2} = 0.0126\)

So 0.0126 = 1.26%.

Answer:

Jasmine;

\(\frac{1}{18}\) more

Step-by-step explanation:

Amie used 7/9 yard of ribbon, and Jasmine used 5/6 yard of ribbon. We can compare these fractions easier if they have the same denominator (bottom number). Let's get a common denominator for these fractions.

7/9 x 2/2 = 14/18

Amie used 14/18 yards of ribbon

5/6 x 3/3 = 15/18

Jasmine used 15/18 yards of ribbon

Which is greater: 14/18 or 15/18? 15/18

To find out how much more, just subtract 14/18 from 15/18:

15/18 - 14/18 = 1/18

Jasmine used 1/18 yards more ribbon than Amie

186 cm³ will be the surface area of the given figure.

To calculate the surface area of the given figure, we need to add the surface area of two cubes and reduce the area of the hidden part.

Thus,

Total surface area = Surface area of bigger cube + surface area of the smaller cube - 2* surface area of the hidden part.

So,

Total surface area = 6*(5*5)+6*(3*3)-2*(3*3)

Total surface area = 150+54-18

Total surface area = 186

The value of angle LAF in the intersecting chords is determined as  104⁰.

The value of angle LAF is calculated by applying intersecting chord theorem, which states that the angle at tangent is half of the arc angle of the two intersecting chords.

Also this theory states that arc angles of intersecting secants at the center of the circle is equal to the angle formed at the center of the circle by the two intersecting chords.

m∠LAF = ¹/₂ (arc LF + arc YS)

From the diagram, we have arc LF = 160⁰ and YS = 48⁰

m∠LAF = ¹/₂ (160 + 48)

m∠LAF = 104⁰

Thus, the value of angle LAF is calculated by applying intersecting chord theorem.

Si Verónica, Ana y Luis están pintando una barda y se les paga un total de 300 unidades monetarias (por ejemplo, dólares, pesos, etc.), para determinar cuánto dinero debería recibir cada uno, necesitamos más información sobre cómo se distribuye el trabajo entre ellos.

Si los tres contribuyen de manera equitativa y realizan la misma cantidad de trabajo, podrían dividir el pago de manera igualitaria. En ese caso, cada uno recibiría 100 unidades monetarias (300 dividido entre 3).

Sin embargo, si uno de ellos realiza más trabajo o tiene una mayor responsabilidad en la tarea, podría ser justo que reciba una porción mayor del pago. En ese caso, la distribución de los 300 unidades monetarias dependerá de un acuerdo previo entre ellos sobre cómo se divide el pago en función de la cantidad o calidad del trabajo realizado.

Step-by-step explanation:

The common ratio is the ratio between two numbers next to each other To find the common ratio, divide a term by the preceding term.

For example, if the term is 48, divide by -96.

48/-96 = -1/2

Another example, if the term is -24, divide by 48.

-24/48= -1/2

Let’s try one more example. If the term is 12, divide by -24

12/-24= -1/2
