If the 1st and 10th terms of geometric sequence are 4 and 100. Fine the nth term of the sequence
gulaghasi [49]
A(n)=ar^(n-1)  so

100=4r^9

25=r^9

ln25=9lnr

ln25/9=lnr

r=e^(ln25/9)

a(n)=4e^((n-1)(ln25/9)  if you wanted an approximation...

a(n)=4(1.43^(n-1))

A process that produces computer chips has a mean of .04 defective chips and a standard deviation of .003 chips. The allowable v
gulaghasi [49]

Answer:

The capability index for the process is 0.889

Step-by-step explanation:

Here, we want to compute the capability index for the process

To get this, we need some important parameters which we already have stated in the question

USL ( upper standard limit) = 0.048

LSL (lower standard limit) = 0.032

mean = 0.04

standard deviation = 0.003

We apply the formula as seen in the attachment below

Kindly understand that we are to calculate the Z upper and Z lower

The smallest value between the two will be our Z minimum

This is what we shall apply in the capability index formula which mathematically is;

Z minimum/3

From calculation:

Z lower = Z upper = 2.67

So therefore;

capability index = 2.67/3 = 0.889
