Answer:
And if we solve for y we got:
And replacing we got:
And we got:
And for x we got:
So then the length would be 76 and the width we got 12.5
Step-by-step explanation:
For this case we have a rectangle. The perimeter is given by:
Where x represent the length and y the the width. We can set the following conditions:
And if we replace the conditions we got:
And if we solve for y we got:
And replacing we got:
And we got:
And for x we got:
So then the length would be 76 and the width we got 12.5
Answer:
Step-by-step explanation:
Answer:
D. We can be 95% confident that the proportion of all cell phone users who use text messaging is between 73.1% and 76.9%.
Step-by-step explanation:
The interpretation of a confidence interval of level x% means that we are x% sure that the interval contains the true mean of the population.
In this problem, we have that:
The population are all the cell phone users.
The 95% confidence interval is (73.1%, 76.9%).
Which of the following is an appropriate interpretation of the 95% confidence interval?
D. We can be 95% confident that the proportion of all cell phone users who use text messaging is between 73.1% and 76.9%.
Start from the end. 5+4*2. Which in turn equals 18 inches.
Answer: The first equation is an equation of a parabola. The second equation is an equation of a line.
Explanation:
The first equation is,
In this equation the degree of y is 1 and the degree of x is 2. The degree of both variables are not same. Since the coefficients of y and higher degree of x is positive, therefore it is a graph of an upward parabola.
The second equation is,
In this equation the degree of x is 1 and the degree of y is 1. The degree of both variables are same. Since both variables have same degree which is 1, therefore it is linear equation and it forms a line.
Therefore, the first equation is an equation of a parabola. The second equation is an equation of a line.
