Step-by-step explanation:
Hello,
If the teacher has 1/2 of an eraser, and she divides it into 2 pieces to give 1 to each of her students, she gives (1/2) / 2 = (1/2) * (1/2) = 1/4 of the eraser to each student.
Each student takes home 1/4 of the eraser.
Hope this helps!
Answer:
<em>795.596≤u≤804.403</em>
Step-by-step explanation:
Confidence interval is expressed using the formula;
CI = xbar ± (z*s/√n)
xbar is the sample mean
z is the z score at 98% confidence
s is the standard deviation
n is the sample size
Given
xbar = 800
z = 2.33
s = 10
n = 28
Substitute into the formula;
CI =800 ± (2.33*10/√28)
CI = 800 ± (2.33*10/5.2915)
Ci = 800± (2.33* 1.8898)
CI = 800 ± 4.4033
CI = (800-4.4033, 800 + 4.4033)
CI = (795.596, 804.403)
<em>Hence an interval estimate of u with 98% confidence is expressed as </em>
<em>795.596≤u≤804.403</em>
(6-x)=24
X=-18
If you subtract a negative number with a positive number it adds them together making it positive (6- -18)=24
