The area of a triangle with base 'b' and height 'h' is given by the formula:
It is given that the area of a triangle is 
.
It is given that the base of the triangle is 5 times the height.
So, 
We have to determine the height of the triangle.
Since, 
So, 
So, h = 24 cm
Therefore, the height of the triangle is 24 cm.
Option 2 is the correct answer.
Answer:
x+63=90(complementary angle)
x=90-63
x=27
Answer:
1
Step-by-step explanation:
Given the question above :
The probability distribution :
X : ___ 1 ___ 2 ___ 3 ___ 4 ____ 5
P(x): _ 0.1 __ 0.1 __ 0.6 _ 0.1 __ 0.1
The Variance : Var(X) = (Σx²*p(x)) - μ²
μ = E(X) = Σ(X * p(x)) :
Σ(X * p(x)) = (1*0.1)+(2*0.1)+(3*0.6)+(4*0.1)+(5*0.1)
μ = 3
Var(X): [(1^2*0.1)+(2^2*0.1)+(3^2*0.6)+(4^2*0.1)+(5^2*0.1)] - 3²
= 10 - 9
= 1
Hence. Variance = 1
Answer:
78.539816 ft²
Step-by-step explanation:
To calculate a circle's area you have to multiple pi with the square of the circle's radius (the radius of a circle is half of its diameter): π·5ft²
5ft² = 5ft·5ft = 25ft
π = 3.14159...
