Answer:
Z score with a confidence level of 95% is 1.96
Step-by-step explanation:
The computation of the z score with the confidence level of 95% is shown below:
While determining the margin of error for the normally distributed population from the sample, the z score of the confidence level of 95% is 1.96
The same is to be considered
Therefore the third option is correct
Answer:
x = p/11, y = 13p/11
Step-by-step explanation:
Adding a positive to a negative, you would look at the number with the greater absolute value, and that number would determine the sign of the sum.
5 - 3 = 2
Since 5 is bigger, you use that sign
-5
-2
Answer: -2
Answer: Midpoint
<u>Step-by-step explanation:</u>
Midpoint is the point that is equal distance from the endpoints.
Answer:
74 and 27
Step-by-step explanation:
let x and y be the numbers
x + y =101........eqn 1
x - y = 47.......eqn 2
solve simultaneously
from equation 2, make x the subject
x= 47 + y........eqn 3
put eqn 3 into eqn 1
(47+y) + y = 101
47 + 2y = 101
2y= 101 - 47
2y=54
y= 54/2
y= 27
put y=27 into eqn 3
x = 47 + 27
x = 74
