This knowledge will be built on in Year 6, particularly when learning about the order of operations, when children may learn the term ‘indices’ (an ‘index number’ is the name for the little 2 used to mean ‘squared’, or the little 3 used to mean ‘cubed’). By Year 5 and ...

The square root of a given number is the positive number (or zero) so that when squared results in that given number . That is it. So, given a number xx, its square root is a number bb so that b≥0b≥0 and b2=xb2=x By looking at the above expression, we can see that if ...

R squared (R2) or coefficient of determination is a statistical measure of the goodness-of-fit in linear regression models. While its value is always between zero and one, a common way of expressing it is in terms of percentage. This involves converting the decimal number into a figure from...
A question may or may not specify the number of choices to select. Sample Questions Directions: Select one or more answer choices according to the specific question directions. If the question does not specify how many answer choices to select, select all that apply. The correct answer may be...
, where S is the sum of the squared differences, ( for 1 ≤ i ≤ n. If the standard deviation of the 5 number 20-2c, 20-c, 20, 20+c, and 20+2c is greater than 6, which of the following could be the value of c? Indicate all such values. ...
For evaluation of Golgi integrity two features were calculated based on the Golgi staining: Minor Axis Intensity (the intensity weighted narrowest dimension of the ellipse of best fit) and Area (the number of microns squared within a mask). These were calculated on the Threshold_60 mask that ...
