Answer:
An 99% confidence interval of the given proportion
(0.355 , 0.385)
Step-by-step explanation:
Given sample size n= 900
the number of successes in the sample is x=333
The proportion P =
Q = 1-P =1 - 0.37 = 0.63
<u>Confidence interval</u>:-
99% of confidence interval zα = 2.93
(0.37 - 0.015 , 0.37 + 0.015)
(0.355 , 0.385)
<u>Conclusion</u>:-
<u>An 99% Confidence interval (0.355 , 0.385)</u>
Amelia must substitute 8 for the variable using parentheses. To simplify, Amelia must multiply 8 by 6. 8 is not a solution of the equation.
<h3>What is algebraic expression?</h3>
Algebraic expression are the expression which consist the variables, coefficients of variables and constants.
The algebraic expression are used represent the general problem in the mathematical way to solve them.
Amelia is using substitution to determine if 8 is a solution to the equation. The equation which is Amelia is solving for a = 8 is,
First, Amelia must substitute 8 for the variable using parentheses as,
To simplify, Amelia must. multiply 8 by 6.
The left hand side of the eqqation is not equal to the right hand side. Thus, 8 is not a solution of the equation.
Thus, Amelia must substitute 8 for the variable using parentheses. To simplify, Amelia must multiply 8 by 6. 8 is not a solution of the equation.
