A LR parser is called a shift-reduce algorithm, because in most cases it either shifts the next lexeme of input onto the parse stack or reduces the handle that is on top of the stack.
<u>Explanation:</u>
A parser is that aspect of the compiler which practices a token string as input and with the sustenance of enduring grammar, transforms it into the identical parse tree. The LR parser is a non-recursive, shift-reduce, bottom-up parser. It utilizes a broad range of context-free grammar which gives it the most valuable syntax analysis procedure.
LR means that the data is examined left-to-right and that a rightmost source, in reverse, is assembled. LR parsers relish time and space extended in the size of the input. Practically all programming languages possess LR grammars.
To get the variance, start with finding the mean of your data points:
(23 + 19 + 22 + 30 + 28) / 5 = 24.4
Now take each data point and subtract the mean from it, then square that value:
23 - 24.4 = -1.4 * -1.4 = 1.96
19 - 24.4 = -5.4 * -5.4 = 29.16
22 - 24.4 = -2.4 * -2.4 = 5.76
30 - 24.4 = 5.6 * 5.6 = 31.36
28 - 24.4 = 3.6 * 3.6 = 12.96
Now get the average of those new numbers. That is your variance:
(1.96 + 29.16 + 5.76 + 31.36 + 12.96) / 5 = 16.24
The standard deviation will be the square root of the variance:
√(16.24) = 4.0299 (rounded to 4DP)
Answer:
1/3×2/3=2/9
Step-by-step explanation:
When you multiply two of the same fraction, the numerator stays the same but the denominator gets bigger. Therefore, you have a smaller fraction.
Y=M(x)+B
Y=4+30
4 is your slope; Y-intercept is 30
