Answer
ways
the coin can land tails either exactly 8 times or exactly 5 times in
ways
Step by step explanation:
THis is a binomial distribution
Binomial distribution gives summary of the number of trials as well as observations as each trial has the same probability of attaining one particular value.
P(9)=(14,9).(0.5)⁹.(0.5)¹⁴⁻⁹
p(3)=(14,3).(0.5)⁹.(0.5)¹⁴⁻³
p=(9)+p(3)
p=C(14,9)(0.5)¹⁴ + C(14,3). (0.5)¹⁴
P= (0.5)¹⁴ [C(14,9) + C(14,3)]
P= (0.5)¹⁴ [2002 * 364]
P= 1/16384 * (2002 +364)
P= 91091/2048
P= 0.144
Hence,the coin can land tails either exactly 8 times or exactly 5 times in
ways
To eliminate the i in the denominator, you multiply it by (6+5i), because (a+b)(a-b)=a²-b², we need i² to eliminate i. Recall that i²=-1
-1(6+5i)/(6-5i)(6+5i)=(-6-5i)/[6²-(5i)²]=(-6-5i)/(36-25i²)=(-6-5i)/61
your choices are all correct. You need to check the 7th answer as well.
Answer:
look at this image for explation .sory it is not clear
Ronny placed 0.15 that means fifteen percent. Celina placed three that means 15 percent once again. Jack placed 30 percent. Therefore michelle places 100 - 60 equal to 40 percent. That is the highest
R = l + (3w)/2
Subtract 'l' to both sides:
r - l = (3w)/2
Multiply 2 to both sides:
2r - 2l = 3w
Divide 3 to both sides:
w = (2r - 2l)/3
