Answer:
The sample would double in 9 hours
Step-by-step explanation
The number of hours it will take for the sample to double can be found using the 72 rule.
The 72 rule is such that a growth rate would double itself by it is used in dividing the number 72 as shown below:
number of hours =72/8=9 hours
The number of hours it would take the sample to double is 9 hours as computed above.
In this question, we made a license that does not allow repeated digit and letter. That means the probability count of letter and digit will be decreased by 1 for every roll.
There is 10 kinds of digits (0-9) and 26 kinds of letters (a to z). So, 2 digits and 5 letter would be:
(10 * 9) * (26 * 25 * 24 * 23 * 22)= 710424000 kinds of license plates
Answer:
1,42 * 10 ^ -5
Step-by-step explanation:
La notación científica también se conoce como forma estándar.
Tenemos que realizar la siguiente operación y dejar el resultado en forma estándar.
Entonces;
0,00000826 * 235 × 10 ^ -7 / 0,0017 × 10 ^ -2
También;
8.26 * 10 ^ -6 * 2.35 * 10 ^ -5 / 1.7 * 10 ^ -5
= 19,411 * 10 ^ -11 / 1,7 * 10 ^ -5
= 1,42 * 10 ^ -5
