Answer:

5.952

Explanation:

First, we need to find the mean of the data. So, the sum of all the values divided by the number of values is equal to:

$\begin{gathered} \text{Mean = }\frac{31.8+22.6+13.8+16.4+28.1}{5} \\ \text{Mean =}\frac{112.7}{5}=22.54 \end{gathered}$

Then, we need to find the absolute difference between each value and the mean, so:

| 31.8 - 22.54 | = 9.26

|22.6 - 22.54 | = 0.06

|13.8 - 22.54 | = 8.74

| 16.4 - 22.54 | = 6.14

| 28.1 - 22.54| = 5.56

Finally, sum the differences and divide them by the number of values:

$\frac{9.26+0.06+8.74+6.14+5.56}{5}=\frac{29.76}{5}=5.952$

Therefore, the mean absolute deviation is 5.952

Given that 2sin^2 theta + sin theta -1 = 0, find the two values for sin theta.

Lisa [10]

2sin^2 θ + sin θ - 1 = 0
2sin^2 θ + 2sin θ - sin θ - 1 = 0
2sin θ(sin θ + 1) - 1(sin θ + 1) = 0
(2sin θ - 1)(sin θ + 1) = 0
2sin θ - 1 = 0 or sin θ + 1 = 0
sin θ = 1/2 or sin θ = -1

The two values of sin θ are 1/2 and -1

Liam says that the graph of the function between x=1 and x=3 is non linear and increasing . What error could he have made in ana

____ [38]

I would say that (d) is the correct answer because the section between x=4 and x=6 is not linear but exponential but it is still increasing. The section between x=1 and x=3 however is linear and therefore his answer is incorrect.
