1.draftSolve ax+b=fg(cx+d) for x. A video is included in Show steps which goes through a similar example.
-
2.draftExpand (ax+b)(cx+d).
-
3.draft
-
4.draftFind the equation of a straight line which has a given slope or gradient m and passes through the given point (a,b). There is a video in Show steps which goes through a similar example.
-
5.draft
-
6.Ready to useFinding the value of a variable
-
7.Ready to useSolve for x and y: a1x+b1y=c1a2x+b2y=c2The included video describes a more direct method of solving when, for example, one of the equations gives a variable directly in terms of the other variable.
-
8.Has some problemsSolve for x: ax2+bx+c=0. Entering the correct roots in any order is marked as correct. However, entering one correct and the other incorrect gives feedback stating that both are incorrect.
-
9.Ready to useSolve for x: abx+c+d=s
-
10.Ready to useWhat is the value of the expression given a choice of n?
-
11.draftTopics covered are calculating the mean, median, mode, range, and standard deviation.
-
12.draftApplication of the binomial distribution given probabilities of success of an event. Finding probabilities using the binomial distribution.
-
13.Ready to useSimple probability question. Counting number of occurrences of an event in a sample space with given size and finding the probability of the event.
-
14.draft
-
15.draftGiven random set of data (between 13 and 23 numbers all less than 100), find their stem-and-leaf plot.
-
16.draftChoosing whether given random variables are qualitiative or quantitative.
-
17.draftFinding the coordinates and determining the nature of the stationary points on a polynomial function
-
18.draftGiven a table of the number of days in which sales were between £x1000 and £(x+1)1000 find the relative percentage frequencies of these volume of sales.
-
19.draft
-
20.draftGiven a random variable X normally distributed as N(m,σ2) find probabilities P(X>a),a>m;P(X<b),b<m.
-
21.draftGiven descriptions of 3 random variables, decide whether or not each is from a Poisson or Binomial distribution.
-
22.Ready to useApplication of the binomial distribution given probabilities of success of an event. Finding probabilities using the binomial distribution.
-
23.draftApplication of the Poisson distribution given expected number of events per interval. Finding probabilities using the Poisson distribution.
-
24.Ready to useQuestion on the exponential distribution involving a time intervals and arrivals application, finding expectation and variance. Also finding the probability that a time interval between arrivals is less than a given period. All parameters and times randomised.
-
25.Ready to useExercise using a given uniform distribution X, calculating the expectation and variance. Also finding P(X≤a) for a given value a.
-
26.draftFinding the confidence interval at either 90%, 95% or 99% for the mean given the mean and standard deviation of a sample. The population variance is not given and so the t test has to be used. Various scenarios are included.
-
27.Ready to useFinding the confidence interval at either 90%, 95% or 99% for the mean given the mean of a sample. The population variance is given and so the z values are used. Various scenarios are included.
-
28.draftFind a regression equation given 12 months data on temperature and sales of a drink.
-
29.draftGiven two sets of data, sample mean and sample standard deviation, on performance on the same task, make a decision as to whether or not the mean times differ. Population variance not given, so the t test has to be used in conjunction with the pooled sample standard deviation. Link to use of t tables and p-values in Show steps.
-
30.draftProvided with information on a sample with sample mean and standard deviation, but no information on the population variance, use the t test to either accept or reject a given null hypothesis.
-
31.draftProvided with information on a sample with sample mean and known population variance, use the z test to either accept or reject a given null hypothesis.
