Answer:
One
Step-by-step explanation:
The most triangles you can make from three given sides is <em>one</em>.
However, you may not be able to make any.
To form a triangle, the sum of the two smaller sides must be <em>greater than</em> the longest side.
16 + 11 > 26, so you can form one triangle: an obtuse scalene triangle.
Answer:
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 67
Variance = 3.85
We have to find 80% confidence interval for the population variance of the weights.
Degree of freedom = 67 - 1 = 66
Level of significance = 0.2
Chi square critical value for lower tail =
Chi square critical value for upper tail =
80% confidence interval:
Putting values, we get,
Thus, (3.13,4.91) is the required 80% confidence interval for the population variance of the weights.
