Answer:
1/ 3
Step-by-step explanation:
If each of the cards is turned over, the probability of picking up a card of one type P(E) becomes equal to:
=> P(E) = number of cards of the required type/ total number of cards
● Total number of spades( ♤ ) = 3
{the queen, one ace and the nine are all spades}
● Total number of cards = 6
Probability of drawing a spade= 3/ 6
= 1/ 2
● Total number of "7" = 1
● Total number of cards = 6
Probability of drawing a 7
= 1/ 6
Now, what's asked is the difference in the probabilities of drawing a spade and a seven.
= 1/ 2 - 1/ 6
= 3/ 6 - 1/ 6
= 2/ 6
= 1/ 3
Hence, 1/ 3 of a greater chance of drawing a spade over a 7.
Answer:
(2,5) instead of rotating 270 degrees you could rotate 90 degrees clockwise the figure is going to end up in quadrant 1 and the numbers stay the same put become positive

Answer:
x (7+2x) = 372,
where 372 is the are of this rectangle, and 
is its width.
Step-by-step explanation:
The width of this rectangle is . Twice that width will be equal to 
.
The length of this rectangle is seven more than twice the width of this rectangle, or seven more than . The length of this rectangle will thus equal to 
.
The area of a rectangle is equal to the product of its width and its length. The width of this rectangle times its length will be equal to 
.
For this rectangle, this area is equal to 372. In other words,
.
This equation about represents the relationship between the width, length, and the area of this rectangle.
