Answer:
8.86 x 10^8
Step-by-step explanation:
Scientific notation means that you represent the standard form of a number like this:
number less than ten x 10 to the ___ power
In standard form, the decimal point is at the end of 886,000,000.
You have to move the decimal point to the left until it creates a number less than 10, but greater than 1:
8.86,000,000
You count how many decimal places you moved it. In this case, it is 8.
So your answer becomes 8.86 x 10^8
Answer:
Step-by-step explanation:
The probability that in any one sample, two calculators or less will be faulty is; 100%
<h3>Probability and Random sampling</h3>
According to the task content;
- A statement of fact indicates that; 20% of the calculators produced in a factory are faulty.
Hence, it follows that, when a sample of 10 calculators is selected randomly each day, 2 of the calculators are faulty by proportion.
Ultimately, the probability that in any one sample, two calculators or less will be faulty is; 100%.
