Explanation Given Information: The provided equation is 10.2 y − 7.3 y = − 58 . Formula used: Addition property: If a = b , then a + c = b + c , where a , b , and c , are any real numbers. Multiplication property: If a = b , then a ⋅ c = b ⋅ c , where a , b , and c , are any real numbers and c ≠ 0 . Division property: If a = b , then a c = b c , where a , b , and c , are any real numbers and c ≠ 0 . To solve an equation with decimals: Firstly find the greatest number of decimal places in the equation then multiply every term on both sides of the equation by 10 if the greatest number of decimal places is 1. Similarly, multiply by 100, if it is 2 and so on. Distributive property: For any real numbers a , b , and c ; a ( b + c ) = a b + a c . Calculation: Consider the provided equation, 10.2 y − 7.3 y = − 58 Here, the greatest number of decimal places in any one number is one, so multiply both sides of the equation by 10, 10 ( 10.2 y − 7.3 y ) = 10 ( − 58 ) Apply distributive property to remove the parentheses, 10 ( 10

Addition Rule of Probability

It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.

Expected Value

When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known …

Probability Distributions

Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosi…

Basic Probability

The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the prob…
