Draw the diagonal from the upper trapezium to point B.

So if you have H0: mean_weight >= 70 Ha: mean_weight <70 Reject the null hypothesis would be equivalent to rejecting H0: mean_weight=70 For computing the z-value you would have mean_weight=70.

So give the question a go first and I will check the working out. In this case H0: mean_weight = 70 Ha: mean_weight <= 70.

The null hypothesis is always an equality. The reason for this is computation. Because the definition p-value is p-value = P(getting test statistic that is more contradictory or equally contradictory to the null hypothesis | H0 ) It may help to read Probability and Statistics for Engineering...

I would solve this by inspection. what does y equal when x=0 You will eliminate A Now look at what happens when you approach 0 from the left hand-side and right hand-side Take C) as an example as x -> 0^- then y->0^- Therefore C) is eliminated Now you need to decide for B) Examine what...

So what you have arithmetic sequence. The definition is given below a, a+d, ..., a + (n-1)d We are told a = 1.8, a+ (n-1)d = 1.2 and n = 61. Now you need to solve for d by making it the subject

So you can take look at the handbook. The UNSW Informations System is more IT focused than UNSW commerce major information systems. If your looking for job in IT UNSW information system would probably be better choice

I think it would be best to look at subjects in uni degree not the degree name. This because lack of standardisation plus there might be particular subject you are interested in. But to answer information systems deal with information. E.g. so you made need collect some information that...

Use the table. You should be able find one online or online calculator.

So Z-score does not have to be whole number. How do you calculate the z-score of a random variable X drawn from a **standard normal distribution**. The process of normalisation converts a non-standard normal distribution to a standard distribution. In your textbook there is probably some...

1. P(Postive_test and not_doing_drug) + P(positive_test and doing_drug) 2. P(negative_test | taken_drug) 3. P(positive_test | taken_drug) So the two main things too know are the definition of conditional probability and Bayes theorem. Using the definition or theorem you will be able to answer...

The best source is always textbook with fully worked solutions

I don't understand your question. dy/dx would equal some_mathematical_expression. Give an example.

Give the questions a go first. So we can see what you have tried

anti-derivative. The main way is take the anti-derivative twice to find the original function. There is no other that I know of

So what you have tried? So you have a differential equation and you know f '(-1) = 0. https://www.emathhelp.net/en/calculus-calculator/?action=solve%20differential%20equation

For the first picture you could use the taylor series expansion of sin x around x=0

One point on how cloud computing/databases emerging have led to the use of python packages such as boto. Adobe Flash and html5. How html5 put a end to adobe.

So you would need to refer to examples (this part of the marking criteria) so you would need primary/secondary sources generally 5/6 examples. would reference lists be needed too? Maybe for an assignment not an assessment

Can you show us what you tried first for part ii. Just give it go.
