Answer:

Option b is correct that is a solid and a plane.

Step-by-step explanation:

The cross section means when two three dimensional intersects and gives the two dimensional figure.

Option a:

A solid and a line is not correct because line is not a three dimensional figure.

Option b:

A solid and a plane is correct because both of them are three dimensional figures for example:

If a plane cuts a sphere it will give circle which is a two dimensional figure.

Option c:

A plane and a plane when intersects gives a line which is not a two dimensional figure.

Hence, incorrect.

Option d:

A plane and line is not correct because line is not a three dimensional figure.

Answer:

$(B) P(B)=\dfrac{16}{31}$

Step-by-step explanation:

From the Venn diagram, n(AUB)=31

The given probabilities in the option are calculated below:

$P(A)=\dfrac{21}{31}\\\\P(B)=\dfrac{16}{31}\\\\P(A|B)=\dfrac{P(A\cap B)}{P(B)}= \dfrac{6/31}{16/31} =\dfrac{6}{16}=\dfrac{3}{8} \\\\P(B|A)=\dfrac{P(B\cap A)}{P(A)}= \dfrac{6/31}{21/31} =\dfrac{6}{21}=\dfrac{3}{7}$

The only correct option is the probability of B which is $\frac{16}{31}$

6 (3x-1)-10x. with work please :)

STatiana [176]

Hey there!
Let's break this expression into two parts:
6(3x-1) and -10x

To solve the first part, we need to use the distributive property which states:
a(b+c) = ab+ac

Applying that to this problem, we have:
6(3x) + 6(-1) =
18x - 6

Now, we can take that -10x and put it right back in:

18x - 6 - 10x

Combine like terms and subtract the 10x from the 18x to get:
8x - 6

Hope this helps!

WILL BE MARKED AS BRAINLIEST !!! <br> Solve<br> (−22 −4 + 8)+ (52 + 2 − 25)

anygoal [31]

Answer:

Step-by-step explanation:

1) lets get rid of the parentheses, we dont really need them:

−22 −4 + 8+ 52 + 2 − 25

Following order of operations we need to work from left to right

-22-4=-26

-26+8=-18

-18+52=34

34+2=36

36-25=11

the answer is 11

hope this helps
