Answer:

Answer:

A) 440.44 units³

B) similar figures

C) 1486.485 units³

Step-by-step explanation:

Volume = ⅓× base area × height

= ⅓ × 110.11 × 12 = 440.44 units³

B) he doesn't have to make calculations again because the two pyramids are similar.

If the ratio of sides is given, he can find the other volume using:

(side1/side2)³ = volume1/volume2

(2/3)³ = 440.44/volume2

Volume2 = 440.44 × 27/8

Volume2 = 1486.485 units³

A card is drawn at random from a standard deck of 52 cards. Find the following conditional probabilities. ​a) The card is a diam
Inga [223]

Answer:

a.\frac{1}{13}\\b.\frac{1}{2}\\c.\frac{1}{13}\\d.\frac{1}{13}

Step-by-step explanation:

P(A|B) = P(A and B) / P(B)

Total number of cards = 52

a)

Let A denotes the event that the card is a diamond​ and B denotes the card is red.

P\left ( A|B \right )=\frac{P\left ( A\cap B \right )}{P(B)}\\=\frac{\frac{2}{52}}{\frac{26}{52}}\\=\frac{1}{13}

b)

Let A denotes the event that the card is red​ and B denotes the card is diamond.

P\left ( A|B \right )=\frac{P\left ( A\cap B \right )}{P(B)}=\frac{\frac{2}{52}}{\frac{4}{52}}\\=\frac{1}{2}

c)

Let A denotes the event that the card is nine and B denotes the card is red.

P\left ( A|B \right )=\frac{P\left ( A\cap B \right )}{P(B)}=\frac{\frac{2}{52}}{\frac{26}{52}}\\=\frac{1}{13}

d)

Let A denotes the event that the card is a king and B denotes the card is a face card.

P\left ( A|B \right )=\frac{P\left ( A\cap B \right )}{P(B)}=\frac{\frac{4}{52}}{\frac{12}{52}}\\=\frac{1}{13}

4x-y=2 2x+9y=-12 unsure how to solve
Anna11 [10]
Simple, use the process of elimination to figure this out:

4x-y=2
2x+9y=-12

Convert these, to be able to find either x or y.

2(4x-y=2)   8x-2y=4   multiply by 2.
then
4(2x+9y=-12)  8x+36y=-48

Which makes them

8x-2y=4
-
8x+36y=-48

-38y=52

This simplified makes it y= -26/19.

Then plug y back into the original equation

4x-y=2

4x-(-26/19)=2

Making it x= 3/19.

Thus your Point of Intersection is at (3/19, -26/19)
