If the price of gold went from $460an ounce to $483 an ounce in one week. What was the percent change in the price of gold?

1 answer:

3 0

It was a 5 percent change because if you subtract 460 form 483 you will get 23, then you need to divide 23 by 460. You will get 0.05. You need to multiply that answer by 100 to get 5

Step-by-step explanation:

Hey there!

0.3 = 3/8 (equal to eachother)

Reason: (3/8 = 0.375)

So, 0.3 is equal to eachother.

0.3=0.3

Determine whether F(x)=4x^2-16x+6 has a maximum or a minimum value and find that value

Reil [10]

Answer:

f(x) has a minimum value of -10.

Step-by-step explanation:

It will have a minimum value because the coefficient of x^2 is positive.

To find its value we convert to vertex form:

f(x) = 4x^2 - 16x + 6

= 4(x^2 - 4x) + 6

= 4[(x - 2)^2 - 4] + 6

= 4(x - 2)^2 - 16 + 6

= 4(x - 2)^2 - 10.

So the minimum value is -10.

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:

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