Just good ole algebraic manipulation
2a - b = 8b - 4a
First, Let's Combine Common Terms

(2a + 4a) = (8b + 1b) \\ 6a = 9b
Now Let's Divide

\frac{6a}{6}  =  \frac{9b}{6}  \\ a =  \frac{9b}{6}
Let's Simplify That Fraction

a =  \frac{9}{6}  \times  \frac{b}{1}  \\
Answer

a =  \frac{3b}{2}  \:

Find the 6th term in the sequence
Dimas [21]

Answer:

C.64

Step-by-step explanation:

The first step is to figure out what the sequence is, the first step is 2, 4 the only ways for 2 to get to 4 would be +2 or *2 so we will look at the next step, 4 to 8. The only ways for 4 to get to 8 is +4 or *2, since these both have *2 in common we will check that with all of the terms

2, 4, 8, 16, 32

2 (*2) = 4 (*2) = 8 (*2) = 16 (*2) 32

Since the equation is working we are going to multiply 32 by 2 to get the 6th term

32 (*2) = 64

A cable car starts off with n riders. The times between successive stops of the car are independent exponential random variables
nikitadnepr [17]

Answer:

The distribution is \frac{\lambda^{n}e^{- \lambda t}t^{n - 1}}{(n - 1)!}

Solution:

As per the question:

Total no. of riders = n

Now, suppose the T_{i} is the time between the departure of the rider i - 1 and i from the cable car.

where

T_{i} = independent exponential random variable whose rate is \lambda

The general form is given by:

T_{i} = \lambda e^{- lambda}

(a) Now, the time distribution of the last rider is given as the sum total of the time of each rider:

S_{n} = T_{1} + T_{2} + ........ + T_{n}

S_{n} = \sum_{i}^{n} T_{n}

Now, the sum of the exponential random variable with \lambda with rate \lambda is given by:

S_{n} = f(t:n, \lamda) = \frac{\lambda^{n}e^{- \lambda t}t^{n - 1}}{(n - 1)!}
