We want to find the probability of randomly drawing 3 spades from a standard deck.

The probability of getting 3 spades is 0.0129

Let's see how to get that probability.

A standard deck has 52 cards, 13 of them are spades.

The probability of randomly drawing a spade card is given by the quotient between the number of spades and the total number of cards.

So for the first spade card, the probability is:

p = 13/52

For the second card, take in mind that we already drew a spade card, so now there are 12 spade cards and 51 cards in total, so we have:

q = 12/51

For the final card, there will be 11 spade cards and 50 cards in total, but we will have:

k = 11/50

The joint probability (this is, the probability of getting the 3 spade cards one after the other) is equal to the product of the individual probabilities, so we will get:

P = p*k*q = (13/52)*(12/51)*(11/50) = 0.0129

The probability of getting 3 spades is 0.0129

The total number of ways a girl can choose a two-piece outfit from 9 blouses and 8 skirts is 72.

Permutation is a mathematical calculation of the number of ways a particular set can be arranged, where order of the arrangement matters.

[tex]^{n} P_{r} = \frac{P!}{(n-r)!}[/tex]

Where,

[tex]^{n}P_{r}[/tex] is permutation

n is the number of objects

r is the number of objects selected.

According to the given question.

Total number of blouses = 9

Total number of skirts = 8

So,

the number of ways of choosing one blouse from 8

=[tex]^{8} P_{1}[/tex]

= [tex]\frac{8!}{(8-1)!} \\[/tex]

= [tex]\frac{8!}{7!}[/tex]

= [tex]\frac{8\times 7!}{7!}[/tex]

= [tex]8[/tex]

And the number of ways of choosing one skirt from 9

[tex]^{9} P_{1} \\= \frac{9!}{(9-1)!} \\= \frac{9\times 8!}{8!} \\=9[/tex]

Therefore,

The total number of ways of choosing two piece outfit from 9 blouses and 8 skirts

= [tex]^{8} P_{1} \times ^{9} P_{1}[/tex]

= [tex]8 \times 9[/tex]

[tex]= 72[/tex]

Hence, the total number of ways a girl can choose a two-piece outfit from 9 blouses and 8 skirts is 72.

Answer:

k=2

Step-by-step explanation:

2x-8y+k/2=0

puting the values of x and y

2*2-8*1+k/2=0

4-8+k/2=0

-4+k/2=0

k/2=4

sing changes if side changed

k=4/2

k=2

We first substituted the X and Y in the equation, so 2 instead of X and 1 instead of Y.

Then I moved the K to make it the subject of the equation by algebra which gave me a -K, but I want k not negative k so I multiplied everything by -1 because, -1 × -1= +1 so K=2.

Step-by-step explanation:

it is NOT a function, because one x value (13) has more than one associated result value (2 and 4). that violates the basic principle of a function.

anyway, the domain is the interval or set of the valid values for x, and the range the interval or set of the valid values for y.

the domain is {13, 18, 39, 51}

the range is {-5, 2, 4}

Answer:

y = 1/3x + 5

Step-by-step explanation:

Slope = (change in y)(change in x)

Slope = (6 - 5)/(3 - 0)

Slope =  1/3

Substitute m = 1/3 and one given ordered pair  into y = mx + b. using (3, 6)

y = mx+ b

6 = 1/3(3) + b

6 = 1 + b

5 = b

the equation is y = 1/3x + 5

Answer: 25 miles

Step-by-step explanation:

Explanation: He will run 5 hours= 5x5=25

Answer:

25 miles

Step-by-step explanation:

I'll create a set of proportions to figure out the answer (represented by x):

2:10 = 5:x

It looks like our proportion on the left, 2:10, can be simplified by dividing both sides by 2 to get 1:5.

1:5 = 5:x

You can multiply 1 by 5 to get 5, so we should be able to multiply 5 by 5 to get the value of x. 5 times 5 is 25, so the answer to the question is 25 miles.
