Answer:
b. 2/15
c. 7/15
Step-by-step explanation:
total frequency = 45
X 0 1 2 3 4 5 6 7
P(x) 1/45 7/45 2/45 1/15 4/45 1/9 2/15 7/45
b. P(≥4) = 18/45 = 2/5
c. P(<3) = 21/45 = 7/15
Answer:
Step-by-step explanation:
Remember 
You are given the fraction 
First, multiply the numerator and the denominator by -2-3i:
This gives you 13 in denominator, now multiply two complex numbers in numerator:
Thus, the initial fraction is
It is 5 2/5
. Also it can be 5.4
Okay so, 0.005,..................
Answer:
an = 4/3n - 13/3.
Step-by-step explanation:
The first term is a1,
a24 = a1 + 23d
83/3 = a1 + 4/3* 23
a1 = 83/3 - 92/3
a1 = -9/3 = -3.
So the nth term an = -3 + 4/3(n - 1)
an = -3 + 4/3 n - 4/3
an = 4/3n - 13/3
