Answer:
Step-by-step explanation:
first, you need to know the formulas for volumes for a sphere, cone, and cube.
sphere volume is defined: V=4/3πr^3
cone volume is defined: V=πr^2(h
/3)
cuboid volume is defined: V=lwh
Then just plug in:
sphere volume=4/3π6^3=904.78
cone volume=π5^2(13
/3)=340.34
cuboid volume=11*6*5=330
Answer:The mean number of checks written per day = 0.3370
The standard deviation = 0.5805
The variance = 0.3370
Step-by-step explanation:
Let the random variable x represent the number of checks he wrote in one day.
Given : The number of checks written in last year = 123
Let the number of days in the year must be 365.
Now, the mean number of checks written per day will be :-

We know that in Poisson distribution , the variance is equals to the mean value .


Thus, Standard deviation = 0.5805
