Answer:
13/102
Step-by-step explanation:
In a standard deck of 52 cards, there are 13 black spades, 13 black clubs, 13 red diamonds and 13 red hearts. There are 26 <u>black </u>cards in the deck of 52 cards.
Probability of drawing a black card = 26/52 = 1/2
Suppose we drew the black card. There are now <u>only 51</u> cards left in the deck. ALL of the hearts are still there - <u>13</u> of them.
Probability of drawing a heart from this deck of 51 = 13/51
In general, for the probability of event A <u>and then</u> event B, we multiply.
1/2 x 13/51 = 13/102
Answer:10 m
Step-by-step explanation:
Given
Scaling ratio 1:1000
i.e. one unit in map is equal to 1000 unit in actual distance
therefore if the distance between two points is 1 cm in map then
it is 1000 cm in reality
Multiplying 3/7 by the reciprocal of -3/14,

Hope it helps!!
Answer:

Period is 2π
Horizontal shift = 0
Step-by-step explanation:
We know that
and as
, so, we can write
Therefore, the if
then
(Answer)
Now, the period of
is 2π, hence the period of
is also 2π. (Answer)
Again.
, hence, the horizontal shift of
is 0. (Answer)
