Step-by-step explanation:
Given :The owner of a restaurant is reviewing customer complaints. In a random sample of 227 complaints, 57 complaints were about the slow speed of the service.
To Find :Create a 95% confidence interval for the proportion of complaints that were about the slow speed of the service.
Solution:
n = 227
x = 57
Formula of confidence for proportion: to
z at 95% is 1.96
Substitute the values in the formula :
Confidence for proportion: to
Confidence for proportion: to
Hence 95% confidence interval for the proportion of complaints that were about the slow speed of the service is to
The expressions are:
- (5x² - 6)/ 2
- 5x² - 18/2
- 5x² -6 /2
<h3 /><h3>What is expression?</h3>
A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
- An absolute numerical number is referred to as a constant.
- Variable: A symbol without a set value is referred to as a variable.
- Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.
- Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.
Given:
15 x squared minus 18 end quantity over 6.
= 15x² - 18 / 6
= 3(5x² - 6)/ 6
= (5x² - 6)/ 2
and, 5 x squared minus 18 end quantity over 2
= 5x² - 18/2
and, 5 x squared minus 6 end quantity over 2
= 5x² -6 /2
