Multiply both the top and the bottom by (4-3i) to eliminate i in the denominator:
10(4-3i)/(4+3i)(4-3i)=(40-30i)/[4²-(3i)²]=(40-30i)/25
reduce: (8-6i)/5
a=8, b=5, c=6, d=5
Answer:
the cosine of x is 60
Step-by-step explanation:
Answer:
P(6) = 5
Step-by-step explanation:
The dice is cast 30 times (k = 30)
So if the big numbers apply, then you would expect the outcome to be evenly distributed, meaning
5 x 1
5 x 2
5 x 3
5 x 4
5 x 5
5 x 6
____ +
30 casts in total (evenly distributed over all numbers of the dice)
P(6) = 1/6 * 30
P(6) = 5
The answer is D. 7x 4y and 1
