Answer: CI = (0, 8)
Step-by-step explanation: The confidence interval for the difference in means is given as
Lower limit
= (x1 - x2) + margin of error
Upper limit
= (x1 - x2) - margin of error
Where x1 - x2 = 8 and the margin of error = 8
For the lower limit,
= 8 - 8 = 0
For the upper limit
= 8 + 8 = 16
Thus, CI = (0, 8)
A school principal utilized a bar chart to present his report, where he allocated the horizontal axis for the names of the students and the vertical axis for their grades. In this setup, the x-axis represents the names of the students, while the y-axis shows their respective grades. To convey complete data, there should be multiple bars for each student, as one single bar wouldn't provide thorough information.
Response:
n = 0 or 3
Detailed explanation:
2n² - 5n + 2
2n² - 4n - n + 2
2n(n - 2) -1(n - 2)
(n - 2)(2n - 1)
A prime number is defined as one that can only be divided by itself and 1
Setting n-2 = 1 gives n = 3
Setting 2n-1 = 1 gives n = 0
20*117.98 + 20*124.32 = $4846.00
<span>$4846.00*1.02 = $4942.92 </span>
<span>40*128.48 = $5139.20 </span>
<span>0.02*5139.20 = $102.78 </span>
<span>$5139.20 - $102.78 = $5036.42 </span>
<span>$5036.42 - $4942.92 = $93.50,
Thus, the result is (B)</span>
Given:
There are 4/5 as many students who do not wear glasses as those who do.
60 students wear glasses.
Find the total number of students in the grade.
Calculate 60 * 4/5 = (60 * 4)/5 = 240 / 5 = 48 students who do not wear glasses.
Total students = 60 w/ glasses + 48 w/o glasses = 108 students.
