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,
In a deck of 52 cards, 13 cards are of spades. So drawing 2 spades out of 13 is,
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,
The probability of getting exactly 2 of the cards are spades out of 6 cards will be,
For this case we have that by definition, the equation of the line of the point-slope form is given by:
Where:
m: It's the slope
It is a point through which the line passes
According to the given statement we have:
Substituting we have:
Finally, the equation is:
Answer:
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
The missing angle is 58.
Step by step:
- We know the triangle is equal to 180
180-57-65 = 58
58 is your answer
Answer:
(1 
, 2 )
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 = 
= 
= 1
Substitute this value of x into either of the 2 equations and solve for y
Substituting in (2)
+ 2y = 6
2y = 6 - = 
( divide both sides by 2 )
y = 
= 2
