Answer:
Step-by-step explanation:
one of them is gonna be alot lighter than the rest so i guess use intuition to find it and then measure its weight. ion have a clue what i just said :(
The outcomes of rolling fair six sided die is 
. The prime numbers in the above outcomes are 
. The probability of not rolling a prime number is 
.
Each trial is independent.
In the given experiment of 100 trials, the binomial probability model can be used to predict the number of occurrence of non-prime numbers (X). The probability mass function is
. Since 
Slope = (9/2 + 1) / (-2 + 5/3)
11/2
= ----------
-1/3
= 11/2 (-3/1)
= -33/2
or
= -16.5
Answer:
84 cm²
Step-by-step explanation:
Surface area of the polyhedron = the sum of the areas of each parts of the net = area of 2 triangles + area of each of the 3 rectangles
Area of 2 triangles:
Base = 4 cm
Height = 3 cm
Area of the 2 triangles = 2(½*base*height)
= 2(½*4*3) = 4*3 = 12 cm²
Area of rectangle with the following dimensions:
Length = 6 cm
Width = 4 cm
Area = length * width = 24 cm²
Area of rectangle with the following dimensions:
Length = 6 cm
Width = 5 cm
Area = length * width = 30 cm²
Area of rectangle with the following dimensions:
Length = 6 cm
Width = 3 cm
Area = length * width = 18 cm²
Surface area of the polyhedron = 12 + 24 + 30 + 18 = 84 cm²
