can fractions be done on a regular caculator?
Jul 3, 2014 · But if you want an immediate answer without any extra thought or scratch-work, you need a calculator that can handle fractions. Note that not all scientific calculators can handle fractions natively. The ones that can have a special fraction key, e.g. the Casio that I used a long time ago in school had an "a b/c" key that allowed you to enter ...
Convert boolean expression into SOP and POS
Convert the following expression into SOP (sum of products) and POS (product of sums) canonical forms using boolean algebra method: $(ac + b)(a + b'c) + ac$ Attempt at solution: $(ac + b)(a + b...
Find the standard matrix for a linear transformation
(After each step you have in each row a vector and its image. This is because of linearity.) If you manage to obtain the identity matrix on the left, then you know the images of the vectors from the standard basis, which is sufficient to obtain the matrix of your linear transformation. (Since you're using column vectors, the result is the ...

How do I combine standard deviations of two groups?
Oct 26, 2018 · This is the formula for the 'pooled standard deviation' in a pooled 2-sample t test. If we may have two samples from populations with different means, this is a reasonable estimate of the (assumed) common population standard deviation $\sigma$ of the two samples.
