It is 10/13.

27 different monsters

No, one half of one third.

none.

There are none.

32,432,400 non-unique combinations (i.e., combinations that may be duplicated).

To determine how many combinations there are, figure out how many choices can be had for each pick and multiply them together.

15 numbers and one can pick 7.

First pick is 1 of 15.

Second pick is 1 of the remaining 14.

...

Seventh pick is 1 of the remaining 9.

So:

15 x 14 x 13 x 12 x 11 x 10 x 9 = 32,432,400.

There are 10 digits from which the first number can be selected, 10 digits from which the second number can be chosen and 10 from which the third number can be picked.

This gives you a total number of combinations of 10 x 10 x 10 = 1000.

The link points to a video that shows a standard way of doing this.

Squared

yes because if you have categorical data you need the range for the value of the numbers so it would be the same for numerical data

1,2,3,4,6

math squares are a good an usefull tool but we may never now who made them lol

create at least two suitable graphical representation (the use of ICT is encouraged) to compare and contrast the prices of the items chosen

NO.

That really depends on whether or not you are at all familiar with the subject at hand: For example, I know NOTHING about brain surgery, so I would "probably" miss EVERY question.

no duffer

yes

Parentheses, or brackets, are often used as a way of indicating that the operation within the parentheses must be evaluated before other operations. Parentheses take top priority in the order in which operations are carried out (PEMDAS in US, BIDMAS in UK).

The median is a more robust measure than the average, which means it is more resilient to the effects of outliers in your dataset.

Pascal's Triangle is an illustration of the coefficients of a binomial expansion. (There are also other patterns within the triangle, but it is primarily taught in relation to binomial expansion.) Each row begins and ends with the number one. The elements in each row are the sum of the two numbers above it in the previous row and continues indefinitely: 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1

Africa has the greatest number of children

younger than 15

Percent error = (actual value - theoretical value) / theoretical value * 100%

0.02 :)

depends on the size of the fish, the filtration, if it is salt or fresh... lots of variables.

A very rough estimate has always been 1 inch of fish per gallon of water.
