Answer:
-7
Step-by-step explanation:
The question says there are 7 employees and there are only 6 salaries. Is there one number missing? I'll continue with 6 numbers, but if there are 7 listed in the question, then my answers will be wrong.
Mean is the average of a given set of numbers. Find the median by adding all numbers in the set & dividing by the quantity of numbers in the set.
Median is the middle number of a given set of numbers. Put list in chronological order and take the center number. In a case of even numbers, average the two center numbers.
CURRENT MEAN (Average)
653 + 667 + 780 + 872 + 885 + 954=
4811
4811 ÷ 6 employees= 801.83
CURRENT MEAN (Middle #)
Since there are 6 numbers, find the average of the two middle numbers
653 667 780 872 885 954
780 + 872= 1652 ÷ 2= 826
NEW MEAN
695 + 667 + 780 + 872 + 885 + 954=
4853
4853 ÷ 6= 808.83
NEW MEDIAN
667 695 780 872 885 954
780 + 872= 1652 ÷ 2= 826
No change in median
ANSWER: The mean goes from 801.83 up to 808.83. The median remains the same at 826.
Hope this helps! :)
(4 + 9 + 16 / 4) - 8 - (3 * 5)
(29 / 4) - 8 - (3 * 5) | Add up the numbers on left side.
(7.25) - 8 - (15) | Divide 29 by 4 and multiply 3 and 5.
-0.75 - (15) | Subtract 8 from 7.25
Final answer: -15.75
Answer:
C=20° a=10.8 c= 4.3
Step-by-step explanation:
first we need to find the value of angle C by subtracting the sum of angle A and B from 180°.
to find c and a we need to use sin rule which states that sinB/b=sinA/a=sinC/c respectively
