Answer: the fourth one
Step-by-step explanation:
Answer:
n=6, m=6√3
Step-by-step explanation:
n = Opposite leg = sin(30°)*hypotenuse = (1/2)*12 =6
m= adjacent leg = cos(30°)*hypotenuse =((√3)/2)*12=6√3
Answer:
5sqrt3
Step-by-step explanation:
Using the pythagorean theorem, we have a^2+4^2=9^2
a^2 + 16 = 81
a^2 = 75.
a = sqrt75.
75 = 25*3. 25 is a perfect square, so sqrt75 = 5sqrt3
A) 17/52
B) 15/26
C) 4/13
A) The probability of getting a club is 13/52; the probability of getting a 3 is 4/52; the probability of a club or 3 is
13/52+4/52 = 17/52
B) The probability of a red card is 26/52; the probability of a King is 4/52; the probability of a red card or King is
26/52+4/52=30/52 = 15/26
C) The probability of a 9 is 4/52; the probability of a face card is 12/52; the probability of a 9 or a face card is 4/52+12/52 = 16/52 = 4/13
