The expressions in which the numbers, or variables, or both, are connected by operational signs (+, - etc.) are called algebraic expressions. For example 5, 4x, a+b, x−y.
The answer is D because there is one of the 0 and one of the 9
Answer:(c)
Step-by-step explanation:
Given : In a hypothesis testing the null hypothesis has been rejected when the alternative hypothesis has been true.
Find : to find that the given decision is create type I error , type II error or right decision has been taken
Step by step :
In hypothesis testing there are 2 types of error.
(1)Type I error :- if the null hypothesis is rejected when it is true, is known has Type I error .
(2)Type II error:- if the null hypothesis is accepted when alternative hypothesis is true, is known as type II error.
Since here null hypothesis has been rejected when alternative hypothesis has been true,i.e., the correct decision has been made
Hence option (c) is correct.
Experimental Probability is use to help make predictions by using materials that relate to the that probability so see if it could happen in real life.
EX: What is the probability of flipling a coin and landing on heads?
When u flip the coin you will have 2 possible choices..heads or tails..so be flipping a real coin you can see your chances ~Amiya
