3, 4, 6, 12

so the figures that can be constructed are ...

triangle . . . . connects every 4th mark
square . . . . . connects every 3rd mark
hexagon . . . .connects every other mark
dodecagon . . connects every mark

_____

Ho do you get the Surface Area of this shape?

blsea [12.9K]

This solid object contains 8 sides.

The side that is facing you has a surface area:

$64f{ t }^{ 2 }+84f{ t }^{ 2 }=148f{ t }^{ 2 }$

The side exactly opposite this one has the same surface area - 2 sides with this surface area in total.

The bottom side has a surface area:

$84f{ t }^{ 2 }$

The side to your right has a surface area:

$84f{ t }^{ 2 }$

The side to your left has a surface area:

$48f{ t }^{ 2 }$

The side to your top left has a surface area:

$48f{ t }^{ 2 }$

The side beside the side to the top left has a surface area:

$36f{ t }^{ 2 }$

The side at the very top has a surface area:

$36f{ t }^{ 2 }$

Combined, the surface area is:

$S=2\cdot 148f{ t }^{ 2 }+2\cdot 84f{ t }^{ 2 }+2\cdot 48f{ t }^{ 2 }+2\cdot 36f{ t }^{ 2 }$

$\\ \\ =296f{ t }^{ 2 }+168f{ t }^{ 2 }+96f{ t }^{ 2 }+72f{ t }^{ 2 }\\ \\ =632f{ t }^{ 2 }$

Therefore the answer is: C

A box of cookies contains 4 chocolate and 6 butter cookies. Miguel randomly selects a cookie and eats it. Then he randomly selec

laila [671]

Answer:

The probability of the flavor of the second cookie is always going to be dependent on the first one eaten.

Step-by-step explanation:

Since the number of the type of cookies left depends on the first cookie taken out.

This is better explained with an example:

Probability Miguel eats a chocolate cookie is 4/10. The probability he eats a chocolate or butter cookie after that is 3/9 and 6/9 respectively. This is because there are now only 3 chocolate cookies left and still 6 butter cookies left.
In another case, Miguel gets a butter cookie on the first try with the probability of 6/10. The cookies left are now 4 chocolate and 5 butter cookies. The probability of the next cookie being chocolate or butter is now 4/9 and 5/9 respectively.

The two scenarios give us different probabilities for the second cookie. This means that the probability of the second cookie depends on the first cookie eaten.
