If 6 cards are drawn at random from a standard deck of 52 cards, what is the probability that exactly 2 of the cards are spades?
nataly862011 [7]

Answer:

<em>The probability of getting exactly 2 of the cards are spades out of 6 cards will be </em><em>0.315</em>

Step-by-step explanation:

6 cards are drawn at random from a standard deck of 52 cards.

The number ways 6 cards can be drawn from a deck of 52 cards will be,

=\ ^{52}\text{C}_6=20358520

In a deck of 52 cards, 13 cards are of spades. So drawing 2 spades out of 13 is,

=\ ^{13}\text{C}_2=78

As exactly 2 must be spades, so the remaining 4 cards must be drawn from other 39 cards of other suits. This can be done in,

=\ ^{39}\text{C}_4=82251

The probability of getting exactly 2 of the cards are spades out of 6 cards will be,

=\dfrac{\ ^{13}\text{C}_2\times ^{39}\text{C}_4}{\ ^{52}\text{C}_6}=\dfrac{78\times 82251}{20358520}=0.315

What is the point-slope form if it's through (1,4) and the slope is 3
Ratling [72]

For this case we have that by definition, the equation of the line of the point-slope form is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It's the slope

(x_ {0}, y_ {0}):It is a point through which the line passes

According to the given statement we have:

(x_ {0}, y_ {0}) :( 1,4)\\m = 3

Substituting we have:

y-4 = 3 (x-1)

Finally, the equation is:

y-4 = 3 (x-1)

Answer:

y-4 = 3 (x-1)

A painter needs to cover a triangular region 60 meters by 77 meters by 89 meters. A can of paint covers 80 square meters of area
bixtya [17]
Perimeter = 60 + 68 +71 = 199
SEMI-Perimeter = 199/2 = 99.5
Area = sq root (99.5 * (99.5-60) * (99.5-68) * (99.5-71)
Area = sq root (99.5 * 39.5 * 31.5 * 28.5)
Area = sq root ( 3,528,381.94 )
Area = 1,878.4 square meters
1,878.4 / 70 sq mtr per can means you will need
26.83 cans OR 27 cans

Estimate the solution to the system of equations. asap, please!! I will mark for brain list
Darya [45]

Answer:

(1 \frac{1}{3}, 2 \frac{1}{3} )

Step-by-step explanation:

Given the 2 equations

7x - y = 7 → (1)

x + 2y = 6 → (2)

Multiplying (1) by 2 and adding to (2) will eliminate the y- term

14x - 2y = 14 → (3)

Add (2) and (3) term by term to eliminate y

15x = 20 ( divide both sides by 15 )

x = \frac{20}{15} = \frac{4}{3} = 1 \frac{1}{3}

Substitute this value of x into either of the 2 equations and solve for y

Substituting in (2)

\frac{4}{3} + 2y = 6

2y = 6 - \frac{4}{3} = \frac{14}{3} ( divide both sides by 2 )

y = \frac{7}{3} = 2 \frac{1}{3}
