Answer:
a. Mean = £27928.57
b. Mean without Deva's income = £19416.67
Step-by-step explanation:
The mean is calculated by dividing the sum of values by number of values. Given 7 values will be used to calculate mean.
So,
Number of values = n = 7
Now,

Rounding off to two decimal places
Mean income = £27928.57
Now we have to calculate mean without Deva's income so the number of values will be 6 and the sum will be:

The mean without Deva's income is:

Rounding off to 2 DP
Mean = £19416.67
Hence,
a. Mean = £27928.57
b. Mean without Deva's income = £19416.67
The cube root is 16. Often times, teachers just let you use calculators on these questions.
For this question, we need the formula τ = F x d<span>, and just plug the numbers in.
</span>
Given the formula <span>τ = F x d</span>
Where τ = torque,
F = force applied, &
d = distance from the axis / hinge,
<span>τ = 300 c 0.8 = 240Nm</span>
Disregard the weight of the door or if there's any friction at the hinge. None of this will change the torque applied.
