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
Answer:
Not parallel.
Step-by-step explanation:
It would be parallel if its slope is also 3.
Calculate slope of line AB = y2 - y1 / x2 - x1
8 - (-2) / 3 - (-1) =
8 + 2 / 3 + 1 = 10/4 = 2.5
2.5 =/= 3, it wouldn't be parallel.
10x-2y=10 We need to solve this equation for "y" to put it into slope intercept form:
10x-2y=10
-2y = -10x +10 Subtracted 10x from both sides
y = 5x - 5 Divided both sides by -2
y = 5x - 5 Is slope intercept form
Answer:
x + 2/5 = 4
subtract 2/5 from both sides
That is
x + 2/5 - 2/5 = 4 - 2/5
x = 4 - 2/5
x = 18/5 or 3 3/5 as a mixed number
