Answer:
NO triangle exists.
Step-by-step explanation:
Given that the sides of the triangle are a=43 ,b=82 , and c=28
To solve for unknown angles of the triangle
PLease refresh the triangle rule of inequality that the sum of any two sides is always greater than the third side
Before solving the triangle, let us check whether this is true.
a+b >c
b+c>a
But a+c is not greater than b.
Hence there cannot be any real triangle with these sides given.
Answer is no triangle exists.
The solution to what you put down is 1,3
Answer:
The first student, with 20 measurements, will have the more precise interval due to the larger sample size.
Step-by-step explanation:
Margin of error of a confidence interval:
The margin of error of a confidence interval has the following format:
In which z is related to the confidence level, s to the standard deviation and n to the sample size.
The margin of error is inversely proportional to the square root of the sample size, which means that a larger sample will lead to a lower margin of error, that is, to a more precise interval.
In this question:
One student will use 5 measurements, other 20. The first student, with 20 measurements, will have the more precise interval due to the larger sample size.
