There were 20 erasers added to each box, because 15 plus 20 is 35. 85 plus 20 is 105, and 35 times 3 is 105. This means that there are 35 erasers in box B after adding 20, and 105 erasers in box A after adding 20. I hope this helps you!
Answer:
Mean = 0.38082 checks per day
Variance = 0.38082
Standard deviation = 0.61711
Step-by-step explanation:
In a Poisson distribution, the variance (V) is equal to the mean value (μ), and the standard deviation (σ) is the square root of the variance.
A year has 365 days,, if 139 checks were written during a year, the mean number of checks written per day is:
Therefore, the variance and standard deviation are, respectively:
Answer:
True,
Definition of equation for you: a statement that the values of two mathematical expressions are equal (indicated by the sign =).
If we simplify 18/27 by 9, the result is 2/3. We get this by dividing both the numerator and denominator by the greatest common factor of 9. So 2/3 has the same proportion as 18/27.
= 18/27
= (18÷9)/(27÷9)
= 2/3
ANSWER: C) 2/3
