Answer:

A. Skew lines cannot lie in the same plane.

Step-by-step explanation:

(*Which)

Skew Line Definition (from Wikipedia): <em>"In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel." </em>-Wikipedia

<em>"Two lines that both lie in the same plane must either cross each other or be parallel, so skew lines can exist only in three or more dimensions."</em> -Wikipedia

Skew lines cannot lie in the same plane so A is correct and C is incorrect.

B and D are incorrect because our friend Wikipedia just said it was incorrect.

g Suppose that a die is rolled twice. What are the possible values that thefollowing random variables can take on:(a) the maximu

KengaRu [80]

Answer:

(a) A = {1, 2, 3, 4, 5, 6}

(b) B = {1, 2, 3, 4, 5, 6}

(d) D = {-5, -4, -3, -2, -1, -0, 1, 2, 3, 4, 5}

Step-by-step explanation:

Assume each roll can result in the numbers 1, 2, 3, 4, 5, or 6.

(a) If both rolls result in a 1, the maximum value is 1. If either roll results in a 6, the maximum value is 6; all integers between 1 and 6 are also possible. Therefore, the possible values are:

A = {1, 2, 3, 4, 5, 6}

(b) If either roll results in a 1, the minimum value is 1. If both rolls result in a 6, the minimum value is 6; all integers between 1 and 6 are also possible. Therefore, the possible values are:

B = {1, 2, 3, 4, 5, 6}

(c) If both rolls result in a 1, the sum is 2. If both rolls results in a 6, the sum is 12; all integers between 2 and 12 are also possible. Therefore, the possible values are:

C = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}

(d) If the first roll results in a 1 and the second results in a 6, the result is -5. On the other hand, if the first roll results in a 6 and the second results in a 1, the result is 5; all integers between -5 and 5 are also possible. Therefore, the possible values are:

D = {-5, -4, -3, -2, -1, -0, 1, 2, 3, 4, 5}

Is 4.15 greater than 4.051

I am Lyosha [343]

Yes (my answer need to be greater than 20 characters long so...Ahhhhh). A way to help you is see it as 4.1 and 4.0 because the # after the 1 aren't that important

Answer:

I believe it's B!

Step-by-step explanation:

y=mx+b

y intercept is b

slope is m

y intercept is positive 5

slope is down 2 to the right 3

y= -2/3x+5

Complete table below then write an equation that relates to x and y

kvasek [131]

I think y is always 3 less than x. So for the first blank it would be 3 less than -1, that is -4. That makes the second blank -3. The third -8. And the last, -5.
The equation might be x-3=y
I might be wrong, please tell me if this is correct.

Answer:

44 cm²

Step-by-step explanation:

To find the area of a compound figure like this, we can divide the shape into various rectangles and compute the areas of them separately before adding them together.

There are several ways to divide this shape, but for this we will section the shape into a 3×3 square, 4×2 rectangle, and a 3×9 rectangle.

To find the areas of them, multiple the length by the width.

For the 3×3 square at the top right-

$A=3\cdot 3$
