Answer:

Step-by-step explanation:

Recall the definition for conditional probability.

We have P(A/D) = P(A and D)/P(D)

P(AD) = 2/17

P(A) = 8/17 and P(D) = 10/17

From the definition of conditional probability,

P(A/D) = P(AD)/P(D) = 2/17 divided by 10/17 = 1/5

But P(D/A) = P(AD)/P(A) = 2/17 divided by 8/17 = 1/4

Hence the two are not equal.

This is because there is a difference in the denominators

Answer:

P(A) ≠ P(D)

Step-by-step explanation:

P(A|D) = P(AD)/P(D)

P(D|A) = P(AD)/P(A)

The two denominators are not equal, so the quotients cannot be equal.

The balcony of an apartment is 4 feet by 7 feet. On a scale drawing of the apartment, the balcony is 0.8 inch by 1.4 inches, and

-Dominant- [34]

Answer:

The actual dimensions of the kitchen are $12\ ft$ by $14\ ft$

Step-by-step explanation:

step 1

Find the scale of the drawing

To find the scale , remember that is equal to the ratio of the corresponding dimension in the drawing divided by the corresponding actual dimension

$\frac{0.8}{4}\frac{in}{ft}=0.2\frac{in}{ft}$

step 2

To find the actual dimensions of the kitchen, divide the dimension in the drawing by the scale

$2.4\ in=2.4/0.2=12\ ft$

$2.8\ in=2.8/0.2=14\ ft$

Assume that you randomly select 6 cards from a deck of 52. what is the probability that all of the cards selected are hearts?

Ira Lisetskai [31]

There are 13 hearts in a 52 deck.

You can think about it like this:

P = (13/52)*(12/51)*(11/50)*(10/49)*(9/48)*(8/47) = 0.00008428903476

Help me with this question, please

anzhelika [568]

Answer:

Part 1: [ -4 = -8 ]

Part 2: Inconsistent

Step-by-step explanation:

Part 1

1. Move all terms that don't contain x to the right side:

3x - 6y+6y = -12+6y

= 3x = -12 + 6y

2. Isolate x:

$\frac{3x}{3} = \frac{-12+6y}{3}$

x = -4 + 2y

3. Substitute the new expression into the original:

-4 + 2y - 2y = -8

4. Simplify:

-4 + 0 = -8

[ -4 = -8 ]

Part 2

The two solutions are not equal in value, so, we can conclude that the system of equations has no solution, or is inconsistent.

hope this helps!
