There are 10 possible digits and 26 possible letters.
To find the answer to this problem we have to multiply 9 as many digits has the hotel reservation number and 26 as many letters it has.
It means:
There are 1,119,214,746 possible reservation numbers.

Step-by-step explanation:
From the set of 100 with 10 defective microprocessors, the probability of picking a defective one is;
10/100 = 1/10
From the set of 99 remaining and 9 defective microprocessors, the probability of picking a defective one is;
9/99 = 1/11
From the set of 98 remaining and 8 defective microprocessors, the probability of picking a defective one is;
8/98 = 4/49
From the set of 97 remaining and 7 defective microprocessors, the probability of picking a defective one is;
7/97
Adding all 4 probabilities together, we get;
1/10 + 1/11 + 4/49 + 7/97 = 0.345 or 34.5%
Answer:
20
Step-by-step explanation:
We can use the Pythagorean theorem to solve
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2+16^2 = c^2
144+256 = c^2
400 = c^2
Take the square root of each side
sqrt(400) = sqrt(c^2)
20 = c
A decimal in the wrong place can change the value of a number completely for example
0.5 can be converted to 50 cents or 1/2 but if you change the decimal 0.05 converts to 5% or 1/20.
