Answer:Tn=29-2n
Step-by-step explanation:
Firstly u determine the differences between the terms and see if it's common. These case the common difference is -2 which means these is a linear pattern.
Now Tn=a+(n-1)d
Tn=27+(n-1)(-2)
Tn=27-2n+2
Tn=29-2n
Answer:
Hello,
19
Step-by-step explanation:
2 methodes:
1)
2)
y'=-8x+20=0 ==> x=20/8=5/2
and y=-4*(5/2)²+20*5/2-6=-25+50-6=19
Are you trying to say find the value of x and y
A
(a) You're looking for
where
Customers arrive at a mean rate of 6 customers per 10 minutes, or equivalently 12 customers per 20 minutes, so
Then
(b) Now you want
This time, we have
so that
B
(a) In other words, you're asked to find the probability that more than 1 customer shows up in the same minute, or
with
So we have
C
(a) Similar to B, you're looking for
with
so that
An infinite series converges when abs(r) < 1.
Therefore, an infinite series converges for r = -2/3 and 3/4
