C is correct Option
Step-by-step explanation:
Let,
Base of the triangle = b = 16
Perpendicular of the triangle = p = 21
Hypotenuse of the triangle= h = ?

Answer:
Mean = 0
Variance = 4/3
Standard Deviation √4/3
a= 0.9
Step-by-step explanation:
If X has a uniform distribution over [a,b] then its Mean is a+b/2 and variance is (b-a)²/12
Here a= -2 and b= 2
Now finding the mean = a+b/2=-2+2/2= 0
Variance = (b-a)²/12=( 2-(-2))²/12= 4²/12= 16/12= 4/3
Standard Deviation = √Variance= √4/3
b) = \int\limits^a_a {\frac{1}{a- (-a)} } \, dx
=1/2a[x]^a_-a= 2a/2a= 1 (applying the limits to the function)
P(−a<X<a) ==1/2 * 2a= a (applying the limits to the function)
P(−a<X<a)= 0.9
a= 0.9
In the given question the limits are -a to a . When we apply these in the above instead of [a,b] we get the above answer.
Answer:
Area of one face of the cube is
Step-by-step explanation:
A cube is a three dimensional figure that has all of its sides equal.
A cube has six square faces:
Surface area of the cube =
where 'a' is the side length of the cube:
Area of one face of a cube=
For surface area of the whole cube: 500 square inches
Dividing by '6' both sides;
Area of one face of the cube is
