Answer:
1. 43/36
2. 1/2
Step-by-step explanation:
1. 7/9 + 5/12
= LCM of 9 and 12 is 36
= 28/36 + 15/12
= (28 + 15) / 36
= 43/36
2. 21/24 - 3/8
= LCM of 24 and 8 is 24
= 21/24 - 9/24
= (21 - 9) / 24
= 12/24
= 1/2
Going by what I was taught in chemistry, there would only be 1.
A distribution of probabilities is a numerical means of describing all unique combinations and the probabilities for a provided random variable, and the further discussion can be defined as follows:
- The distributions mean (average), basic difference, skewness, as well as courtesies, are among such factors.
- A formula, table, or chart can show a probability distribution for discrete probability distribution X that providing for all x.
- For just a discrete random variable, the probability assigns annual probabilities with only a countless multitude of unique x values.
- <em><u>Each result is likely to be between 0 and 1, including.</u></em>
Therefore, the final choice is "Option A".

Answer:
Rational
Step-by-step explanation:
okay so a natural number is anything like 1,2,3,4...etc.
a whole number is like a natural number but includes 0's
an integer is numbers that can have both positive and negative numbers
but keep in mind all of these are whole numbers or can be made into a whole number (not including natural numbers)
this leaves...
Rational
now here is a word of advice every mixed number and fraction is rational because its already in a solved and complete form but a decimal that could be solved like 0.77777 or 0.345 with a line over it or 64 squared
Irrational
a number that has no end and cant be solved like 0.86866968..... or 38 squared
