Answer:
The answer is (-2,3)
Step-by-step explanation:
If you look at the coordinate plane, you'll notice that the x -values are negative and the y-values are positive. So, if you look at where the two lines meet, they meet at the point (-2,3).
Hope I helped!!!
Answer:
A: x‒axis: minutes in increments of 5; y-axis: temperature in increments of 1
Step-by-step explanation:
Let the x-axis represent the minutes
Let the y-axis represent the temperature
Now, from the values given us in minutes, we can see that the difference between the values are Increasing at constant rate of 5 minutes .
Thus, minutes increment on the x-axis is 5.
Now,for the y-axis, the increment is not constant as it fluctuates.
Thus, we cannot use 5 like we did for the x-axis. Rather, the most appropriate temperature increment to be used on this y-axis for ease of locating the points will be 1.
Using the z-distribution, the 95% confidence interval for the proportion is given as follows:
(0.4576, 0.5824).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
is the sample proportion.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of 
, so the critical value is z = 1.96.
The other parameters for the interval are given as follows:
.
The lower and upper bound of the interval, respectively, are given by:
