27 Aarya has a biased 5-sided spinner. pink orange green blue yellow When the spinner is spun once, it can land on blue or yellow or green or pink or orange. Aarya spins the spinner many times and records the colour that the spinner lands on each time. She uses these results to calculate the probability of the spinner landing on each colour. The table below gives the probabilities that Aarya calculated for blue, yellow and green. Colour blue yellow green pink orange Probability 0.22 0.34 0.12 Aarya's calculations showed that the probability of the spinner landing on orange is 3 times the probability of the spinner landing on pink. (a) Complete the table for pink and for orange. When Aarya spun the spinner, it landed on green 90 times. (b) Work out an estimate for the total number of times Aarya spun the spinner.

Equations and inequalities describe the relationship between two mathematical expressions.

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
