Answer: 0.1289
Step-by-step explanation:
Given : The proportion of all students at a large university are absent on Mondays. : 
Sample size : 
Mean : 
Standard deviation = 

Let x be a binomial variable.
Using the standard normal distribution table ,
(1)
Z score fro normal distribution:-

For x=4

For x=3

Then , from (1)
Hence, the probability that four students are absent = 
The insurance Gil has is most likely individual life insurance.
The answers are as follows:
1. Triangles are often used to build different types of support structures because of its beneficial properties. Triangles is rigid in shape and it has strength. When force is applied to the side of a triangle, it can not shift into another shape, this is because its sides and angles are fixed.
2. The properties of triangle that make it a desirable geometric shape for building support structures is its fixed sides, fixed angles, rigidity and strength. Triangles are the strongest shapes and they are stable. Thus, triangle can be easily fix together to provide strength and stability over a wide area.
3. There are different types of triangles, these include: equilateral triangle, scalene, isosceles, right triangle, obtuse and acute. Of all these triangles, the best triangle is equilateral triangle.
4. Triangle is preferred over other types of polygon because, it is the strongest. The other polygons can be bent into different other forms that are not regular polygon, but a triangle always retains its shape and can not be deformed.
Answer:
so that number becomes divisible by 3, 6 and 9.
Step-by-step explanation:
In Number Theory there is a rule of thumb which states that sum of digits of a multiple of 3 equal 3 or a multiple of three. If we know that
, then its sum of digits is:

(Eq. 1)
We have to determine which digits corresponds to multiples of three, there are four digits:
N = 0

(
)
N = 3

(
)
N = 6

(
)
N = 9

(
)
We get the following four distinct options: 154038, 154338, 154638, 154938. Now we find which number is divisible by 6 and 9 by factor decomposition:




It is quite evident that
so that number becomes divisible by 3, 6 and 9.
