__Year 1 Pure__

**page 39, section 3.1**

amend to:

"Linear simultaneous equations in two unknowns,

**that are neither equivalent nor contradictory,**have one set of values that will make a pair of equations true at the same time."

**page 50, example 11**

first line of the solution should say >2 rather than >x, in order to match the question

__Year 1 Applied__

**page 11, bullet point 1**

Daily mean temperature recorded over a 24 hour period is recorded for all locations.

**page 11, second red box**

Ignore final sentence about maximum and mean temperatures.

**page 66 question 3 part a)**

on the graph, amend the x axis label to "Number of items (

*n*)"

**page 67 question 5 part c)**

there is a mismatch between the question and the answer

amend to:

"The equation of the regression line of

*g*on

*t*for the remaining data is

*g*= 44.9 - 0.47

*t*

c) Give an interpretation of the value -0.47 in this regression equation"

page 216 Mixed Exercise 4 question 5 part c)

amend to:

"If the temperature increases by approximately 1 degree C, the number of pairs of gloves sold each month decreases by 0.47."

The Solutionbank answer for this uses the regression line of

*t*on

*g*as given, but has a totally different answer for part c based on 10 gloves predicting a 1.8 degree drop of temperature.
