How many different seven-letter sequences can be formed from the letters a, a, a, a, a, b, c?
Kaylis [27]

If b is in the first position then c can be in any 1 of the remaining 6 positions.

If we start with ab then the letter c can be in any one of 5 positions and  if we have aab there are 4 possible positions for c and so on.

So the total number of possible sequences where b comes first = 6+5+4+3+2+1 =  21.

The same argument applies when c comes before b  so that gives us 21 ways also.

So the answer is 2 *21 = 42 different sequences.

A more direct way of doing  this  is to use factorials:-

answer = 7! / 5!     =  7 * 6 = 42.

 ( We divide by 5!   because of the 5 a's.)

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 411 gram setting. It
nikdorinn [45]

Answer:

0.0445937

Step-by-step explanation:

-Given that the sample statistic has a mean of 406 grams, standard deviation of sq root(225) and the null statistic is 411 grams.

-Assuming normal distribution, the test statistic is calculated as:

z=\frac{Sample \ statistic-Null \ statistic}{\sigma/\sqrt{n}}\\\\=\frac{406-411}{\sqrt{225/26}}\\\\=-1.6997

-we then find the p-value of the test statistic from the z-tables:

P-value=0.0445937
