Solve:-
1.38 = 1.38/1
1.38 × 100 = 138
1 × 100 = 100
138/100
69/50
1 19/50
1.38 = 138/50 = 69/50 = 1 19/50
Answer:
97% confidence interval for the survey is between a lower limit of 0.45 and an upper limit of 0.67
Step-by-step explanation:
Confidence Interval is given by the mean + or - error margin
The lower limit of the confidence interval is found by subtracting the error margin from the mean.
The upper limit is obtained by adding the error margin to the mean.
The interpretation is that the mean is between 0.45 and 0.67
I think it will take it 8 days bcuz 4x8=32 it climbs 5 slides down 1 which is 4
I hope that helped u
There is no solution for the first one
if you eliminate y you get 2 equations
-13x - 13z = -25
-13x - 13x = -15
- there is no solution to theses
a23 means the element in the second row and the 3rd column
so its -5
