Answer:
0.022
Step-by-step explanation:
Given that :
Population size = 25000
n = 500 ; p = 0.4
Size of random sample (n) = 500
5% of population size : 0.05 * 25000 = 1250
Distribution is normally distributed since n < 5% of population size
Hence, the mean of the distribution = p = 0.4
Standard deviation = √((pq) /n)
q = 1 - p ; q = 1 - 0. 4 = 0.6
Standard deviation = √((0.4 * 0.6) /500)
Standard deviation = 0.0219089
= 0.022

Answer:
Isosceles triangle.
Step-by-step explanation:
On the basis of the lengths of the sides of a triangle, below are three types of triangles.
Equilateral triangle: The triangle in which the lengths of all sides are equal.
Isosceles triangle: The triangle in which the lengths of any two sides are equal.
scalene triangle: The triangle in which the lengths all the three sides are different.
Here, the length of the sides are 24 24 and 4.
Since, two sides are equal in length.
Hence, it is an Isosceles triangle.
