Answer:
Step-by-step explanation:
Mean is just another word for average. To find the average, add up all the values then divide by the number of values.
There are 7 values in the first data set. The average is:
(3 + 4 + 6 + 4 + 3 + 1 + 4) / 7 = 25/7 ≈ 3.57
There are 7 values in the second data set. The average is:
(6 + 7 + 2 + 4 + 5 + 5 + 3) / 7 = 32/7 ≈ 4.57
1/u = 1/f -1/v
1/v = 1/u + 1/f
(13 + 20) + 15 = 13 + (20 + 15)
Divide the annual salary by 12 and you'll find the monthly salary
month salary = annual salary/12
month salary = 52,750/12
month salary = 4,395.83
Her monthly salary is $4,395.83
