CONSIDERANDO QUE A U B= { 1,2,3,4,5,6,7,8}, A U B = {4,5} e A-B = { 1,2,3}, DETERMINE O CONJUNTO B

Answers

Answer 1

Answer:

O conjunto B é dado por: B = {4, 5, 6, 7, 8}

Step-by-step explanation:

A U B= { 1,2,3,4,5,6,7,8}

Todos os elementos pertencem a pelo menos um desses conjuntos.

A intersecção B = {4,5}

Os elementos 4 e 5 pertencem a pelo menos um desses conjuntos. Então, tem-se os dois primeiros elementos de B, que são 4 e 5.

A-B = { 1,2,3}

1, 2, 3 são os elementos que pertencem ao conjunto A e não pertencem ao conjunto B.

Como A U B= { 1,2,3,4,5,6,7,8}, tem-se que os elementos 4, 5, 6, 7 e 8 pertencem ao conjunto B.

O conjunto B é dado por: B = {4, 5, 6, 7, 8}

Answers

Answer:

Step-by-step explanation:

360 + 3*180 = -360 + 540 = 180

For four sides -360 + 180*4 = 360

Answers

Answer:

y = -1/2x + 1

Step-by-step explanation:

Slope-intercept form:

y = mx + b, where m - slope, b - y-intercept

We are given two points on the graph:

(0, 1) and (2, 0)

The first point gives us the y-intercept:

b = 1

Finding the slope using slope formula:

m = (y2 - y1)/(x2 - x1)m = (0 - 1)/(2 - 0) = -1/2

The formula of the line:

y = -1/2x + 1

What is the equation of the line that passes through the point (5, 6) and has a slope
of 3/5?

The rectangle below has an areas of x^2+8x+15 square metres and a width of x+3 meters what expression represents the length of the rectangle

Answers

Answer: x+5 or ((x^2+8x+15)/(x+3))

Step-by-step explanation: First let's assign our variables.

x^2+8x+15 = Area

X+3 = Width

? = Length

If the equation of a=lw, then we can substitute in our variables.

a=lw

x^2+8x+15= L (x+3)

Now we must isolate L.

Divide both sides of the equation by 'x+3'

x^2+8x+15= L (x+3)

x+3                 x+3

x+5= L

Find the value of x
Thanks bb please explain

Answers

Answer:

x=24

Step-by-step explanation:

Hello There!

Angle E and angle D are supplementary angles meaning that the sum of the two angles equals 180

So we setup an equation

180=2x+12+5x

step 1 combine like terms

5x+2x=7x

now we have

180=7x+12

step 2 subtract 12 from each side

12-12 cancels out

180-12=168

now we have

168=7x

step 3 divide each side by 7

7x/7=x

168/7=24

we're left with~ x=24

Answers

1. Subtract the second equation from the first and solve for y: 0 - 4y = -20 => y=5
2. Substitute y=5 into one of the equations and solve for x: 4x - 3(5) = -3 => 4x = 12 => x=3

So the solution is (x, y) = (3, 5)

How do you think statistics may at times not say something? How can a well-designed study be used to carefully say everything that is important about a population? Is it possible to do so?

Answers

Answer:

While statistics are extremely valuable, they are also notorious for being a means that people use to make false and misleading arguments. Also far too often statistics are obtained by taking a sample from a larger group and assuming the whole group has the same characteristics as the sample.

A sample provides a smaller set of the population for review, that delivers data that is useful to represent the whole population. Surveying a smaller sample, as opposed to the entire population, can save precious time for researchers and offer urgent data.
