Answer:
The probability that no calls will occur during the next ten minutes is 0.0907.
Step-by-step explanation:
Poisson distribution:
Poisson distribution is a statistical distribution that helps to find out the number of events is likely occur in a specific time period.
Given that,
Calls occur at an average rate of 1.2 every 5 minutes.
The average rate of call is per minute.
Here,
, t=10 and x=0
=0.0907
The probability that no calls will occur during the next ten minutes is 0.0907.
9, 6, 3, 0
a =Ist Term = 9.
Common difference is = T2 - T1 = 6 - 9 = -3.
The sequence is an Arithmetic Progression AP = a + (n-1)*d
Tn = a + (n-1)*d
Tn = 9 + (n-1)*(-3). Expand and simplify.
Tn = 9 - 3n +3.
Tn = 12 - 3n.
Hence the recursive formula is = 12 - 3n. Where n = position of term. n = 1, 2, 3, ..
A squared + B squared = C squared. Collect like terms which gives you what I wrote.
2x+6 <u>></u> -4
trate it as a temporary equals sign
2x+6=-4
subtract 6 rom both sdies
2x=-10
divide both sides by 2
x=-5
put it back
x <u>></u> -5
so the answer is C
