If a polygon does not have six sides, then it is not a hexagon.
Answer: (3-1)×(7+5)
Step-by-step explanation:
There are mainly several ways to get 24
- 2×12
- 3×8
- 4×6
- add all of them together
- complicated ones can include large numbers minus another large number
Use try-check-revise, to find the way that fits 24
For this question, we used 2×12, which results in (3-1)×(7+5)
Hope this helps!! :)

Answer:
8.2+/-0.25
= ( 7.95, 8.45) years
the 95% confidence interval (a,b) = (7.95, 8.45) years
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 8.2 years
Standard deviation r = 1.1 years
Number of samples n = 75
Confidence interval = 95%
z value(at 95% confidence) = 1.96
Substituting the values we have;
8.2+/-1.96(1.1/√75)
8.2+/-1.96(0.127017059221)
8.2+/-0.248953436074
8.2+/-0.25
= ( 7.95, 8.45)
Therefore the 95% confidence interval (a,b) = (7.95, 8.45) years
The larger fractron will be the fraction with the greater numerator.
