Answer:

geometric, with a common ratio of 1/2

Step-by-step explanation:

The sequence is geometric because you get successive trems by <u>multiplying</u><u> </u>the previous term by a certain constant, the 'common ratio'. (If you got each successive term by <u>adding</u> or <u>subtracting  </u>the same constant number each time, that would be an arithmetic sequence.)

In this case, it looks like you get each successive term when you multiply the previous term by 1/2.

Thus, the common ratio is 1/2.

kotegsom [21]

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

ale4655 [162]
We determine the number of cubic yards that James need to order by converting the unit of measurement given in feet to yards. Every yard is composed of 3 feet. Thus, the solution would be,
       (180 ft)³ x (1 yd/ 3ft)³ = 6.67 yd³
Thus, James will have to order 6.67 yd³.
