Answer:
Step-by-step explanation:
Remove the brackets.
ac - bc = d
Add bc to both sides
ac = d + bc
Divide by a
The "a"s cancel and you are left with the answer.
Answer
Because of the Absolute Values, when x = -1 or -2, the overall range
is [-1, co)
Answer:
k = 4
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem we have that:
. So
P(X < k) = 0.6625
k only assumes discrete values, so
We have to find the cummulative distribution until we hit 0.6625. So
So k = 4
Recall 1πrad = 180°
1 rad = 180/π
so
5π/6 rad = 180/π × 5π /6 = 5×30 = 150.00° (to 2Dp)
