Answer:

A.) £27,214.29

B.) £19,250

Step-by-step explanation:

Given the following :

Andy £13500

Bevan £27500

Cheryl £13250

Deva £75000

Elliott £18750

Frankie £27500

Grace £15000

Mean income = (total sum of salaries / number of workers)

Mean income = £(13500 + 27500 + 13250 + 75000 + 18750 + 27500 + 15000) / 7

Mean income = (£190,500 / 7) = £27,214.286

B.) mean income excluding Deva's salary:

Mean income = Mean income = £(13500 + 27500 + 13250 + 18750 + 27500 + 15000) / 7

Mean income = £115,500 / 6

Mean income = £19,250

Confusion...help please
kifflom [539]

Given:

In triangle KLM, KL = 123 cm and measure of angle K is 35 degrees.

To find:

The length of the side KM to the nearest tenth of a centimeter.

Solution:

In a right angle triangle,

\cos \theta =\dfrac{Base}{Hypotenuse}

In the given right triangle KLM,

\cos K=\dfrac{KM}{KL}

\cos (35^\circ)=\dfrac{KM}{123}

0.819152=\dfrac{KM}{123}

Multiply both sides by 123.

0.819152\times 123=KM

100.755696=KM

KM\approx 100.8

The measure of side KM is 100.8 cm.

Therefore, the correct option is (2).
