Answer:
a. £24,714.29
b. £16,833.33
Step-by-step explanation:
The calculation of mean income is given below:-
Mean income = Total addition of salaries ÷ Number of workers
= £9,500 + £25,000 + £13,250 + £72,000 + £12,750 + £29,500 + £11,000
= £173,000 ÷ 7
= £24,714.29
Now,
the Mean income excluding Deva's salary:
= Formula of Mean income
= Total addition of salaries excluding Deva salary ÷ Number of workers
= (£9,500 + £25,000 + £13,250 + £12,750 + £29,500 + £11,000) ÷ 6
= £101,000 ÷ 6
= £16,833.33
Answer:
Step-by-step explanation:
If I’m correct the area is 48
We can conclude that the equation 36x + 9 equals -1/4.
<h3>
What exactly is an equation?</h3>
- An equation, in its most basic form, is a mathematical statement demonstrating that two mathematical expressions are equal.
- 3x + 5 = 14, for example, is an equation in which the expressions 3x + 5 and 14 are separated by a 'equal' sign.
So,
- 36x + 9
- 36x + 9 = 0
- 36x = -9
- x = -9/36
- x = -1/4
Therefore, we can conclude that the equation 36x + 9 equals -1/4.
