How many different three-digit numbers can be written using digits from the set 5, 6, 7, 8, 9 without any repeating digits?
suter [353]

Answer: 60 different numbers can be formed

Step-by-step explanation:

Note that we have 5 different digits, and we must select 3 of them. They should not be repeated

The order of selection is important in this case, because the number 532 is not the same as the number 235.

So we have a permutations problem, where we have a set of n elements and we want to choose r from them.

Then we define the permutacion as:

nPr=\frac{n!}{(n-r)!}

In this case note that n=5 because there are 5 elements in the set.

r = 3 because we combine the elements to form three-digit numbers

Then:

5P2=\frac{5!}{(5-3)!}

5P2=\frac{5!}{2!}

5P2=\frac{5*4*3*2!}{2!}

5P2=5*4*3

5P2=60

A company manufactures a large number of rods. The lengths of the rods are normally distributed with a mean length of 4.4 inches
Elza [17]

Answer:

0.78814

Step-by-step explanation:

We solve using z score

z = (x-μ)/σ, where

x is the raw score = 4.0 inches

μ is the population mean = 4.4 inches

σ is the population standard deviation = 0.5 inches

z = 4.0 - 4.4/0.5

z = -0.8

Probability value from Z-Table:

P(x<4.0) = 0.21186

P(x>4.0) = 1 - P(x<4.0)

= 1 - 2.1186

= 0.78814

The probability that the rod you chose will be greater than 4.0 inches is 0.78814.
