Answer:
3/29
Step-by-step explanation:
There are a total of 10+6+9+5 cards = 30
10 yellow, 6 green, 9 orange, and 5 red cards
Draw a card
P(yellow) = number of yellow cards/ total
=10/30 = 1/3
Now keep the yellow card
There are a total of 19+6+9+5 cards = 29
Draw a card
P(yellow) = number of yellow cards/ total
=9/29
P(yellow, not replaced, yellow) = 1/3 *9/29
=9 /87 =3/29
Step -by-step explanation: the opposite of a number is the number on the other side of the numbers line eg -5 is the opposite of 5 so-12% is the opposite of 12%
Answer:-12%
Answer:
= -cot5x
Step-by-step explanation:
sin7x - sin3x = sin(5x + 2x) - sin(5x - 2x)
= [sin5x cos2x + cos5x sin2x] - [sin5x cos2x - cos5x sin2x]
= 2 cos5x sin2x
cos7x - cos3x = cos(5x + 2x) - cos(5x - 2x)
= [cos5x cos2x - sin5x sin2x ] - [cos5x cos2x + sin5x sin2x]
= -2 sin5x sin2x
so
(sin7x - sin3x)/(cos7x - cos3x)
= -cos5x/sin5x = -cot5x
