Answer:
252 ft squared
Step-by-step explanation:
Since the radius of the circle is 3, then the diameter would be 6
Split the rectangle into 3
The way I split the shape is like the picture attached (with the blue lines).
Find the area of each rectangle which can be easily found by using the diameter of each circle (picture attached with black lines)
6*18=108
6*12=72
6*12=72
Add the areas of each rectangle.
108+72+72=252
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
Answer:
80%
Step-by-step explanation:
The percentage change between two numbers can be calculated as ...
percentage change = ((new value)/(old value) -1) × 100%
= (2700/1500 -1) × 100% = (1.80 -1) × 100% = 80%
Traffic volume increased 80%.
The answer is B. (2 + x) + 3y.
The associative change happened when they just moved the parenthesis.
Hope this helps!
