Answer:

.0615

Step-by-step explanation:

p=.11

n=149

np=16.39 (which is the mean)

x<11 so 10.5...-999

σ= \sqrt{16.39(1-.11)} =3.81930622

normalcdf(-999,10.5,16.39,3.81930622)

= .0615167786

To Find:

The possible value of the third side

Solution:

Definition of Isosceles  triangle:

An isosceles triangle is a triangle with (at least) two equal sides. Isosceles triangle  has both two equal sides and two equal angles.

We also know the property of the triangle that  

Sum of two sides of triangle > third side of the triangle  

Case1. When third side is 10

Thee third side can’t be equal to 10 because it does not follow the rule of triangle  

10+10>26………which is  not possible

So the third side of the isosceles triangle is 26.
