Answer:
Hence the degrees of freedom are associated with the critical value is 25.
Step-by-step explanation:
Using two independent samples, two population means are
compared to determine if a difference exists, the population standard deviation is equal.
sample size 1 = = 15 and sample size 2 =
= 12
since, population standard deviations are equal, required degrees of freedom
Given:
One of the legs of a right triangle is 9 cm.
The area of the triangle is 225 cm².
To find:
The length of the other leg.
Solution:
The area of a triangle is
The area of a right triangle is
Let x be the length of other leg.
Therefore, the length of the other leg is 50 cm.
