Answer:

16.8 metros cuadrados.

Step-by-step explanation:

Dado que se quiere pintar una pared en forma de hexágono regular y se sabe que cada lado mide 3m y que su apotema es de 2,8m, y que el área de un hexágono es igual al perímetro multiplicado por la apotema, y dicho resultado dividido por 2, para determinar cuál es el área que se va a pintar se debe realizar el siguiente calculo:

((6x3) x 2.8) / 2 = X

(12 x 2.8) / 2 = X

33.6 / 2 = X

16.8 = X

Así, el área que se va a pintar es de 16.8 m2.

Answer:

Yes, because the regression equation is based on the random sample.

Step-by-step explanation:

A simple linear regression model that describes the relationship between X and Y takes the form

Yi= ∝ + βXi + εi or

Y i= U(y.x) + εi

where εi's are the random errors. The random errors εi's are assumed to be independent of Xi and normally distributed with E(εi)= 0 and Var (εi)= σ²(y.x) , a constant for all Xi. These assumptions imply that Yi also have a common variance σ²(y.x) ,  as the only random element in the is  εi.

The estimated regression line Y= a+ bX is also the predictor of Yi= ∝ + βXi+ εi

. That is Y^ can also be used to predict an individual value Y0 of Yi rather than a mean value, corresponding to the given X0. To draw the inferences about Y0 we need to know it mean and variance.

Anosh has 35 feathers.

Step-by-step explanation:

Initially, he had 0 feathers.

His father started his collection by giving him 7 feathers.

After his father gave him, he has 7 feathers.

Since then he has collected 28 more feathers. How many feathers does Anosh have?​

So now, he has 7 + 28 = 35 feathers.

Anosh has 35 feathers.

Answer:

2,324.

Step-by-step explanation:

Given that a utility company charges $ 0.12 per kilowatt-hour for energy a customer uses, and they give a credit of $ 0.0025 for every kilowatt-hour of electricity a customer with a solar panel generates that they don't use themselves, if a customer has a charge of $ 82.04 and a credit of - $ 4.10 on this mouth bill, to determine how many kilowatt-hours did they use the following calculation must be performed:

(82.04 / 0.12) + (-4.10 / - 0.0025) = X

683,666 + 1,640 = X

2,323.66 = X

Thus, rounded to the nearest whole number, users used 2,324 kilowatts per hour.

Answer:

x=3

Step-by-step explanation:

2 times a number equals 6

you can divide 6 by 2 to get 3

and then to prove it, make x=3 and rewrite

2 * 3 = 6

Answer:

x=3

Step-by-step explanation:

2⋅x=6

First, we multiply the 2 and the x

2x=6

Next, we transfer the 2 over to the 6. When we do that, we are dividing because we do the opposite of multiplication.

x=6÷2

Solve!

x=3

Answer:

the earned value of the project is $9,900

Step-by-step explanation:

The computation of the earned value of the project is shown below:

As we know that

CPI = Earned value ÷ Actual cost

1.1 =  Earned value ÷ $9,000

So, the earned value is

= 1.1 × $9,000

= $9,900

hence, the earned value of the project is $9,900

Probability that Margaret will get a higher number than Carlos is 3/2.

Probability is the measure of the likelihood of an event to occur.

P(E) = number of favorable outcomes/ total number of outcomes

Where, P(E) is the probability of an event.

According to the question we have,

A spinner goes from 1 to 6.

⇒ sample space = {1, 2, 3, 4, 5, 6}

⇒ Total number of outcomes = 6

Also, Carlos spins 3.

So, the numbers which required to win the game by Margaret are 4, 5 ,6 (greater than 3).

⇒ Total number of favorable outcomes = 3

Therefore,

The probability that Margaret will get a higher number than Carlos = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Triangles

A diagram with angles 74°, 35° and ( 6x + 17 )°.

Value of x.

Sum of all angles in a triangle is 180°.

Sum of all angles in a triangle = 180°

74° + 35° + 6x + 17° = 180°

6x + 74° + 35° + 17° = 180°

6x + 126° = 180°

6x = 180° - 126°

6x = 54°

x = 9

So, value of x is 9.
