Answer: 0.6763 cm∧2
Step-by-step explanation: Variance is one of the measures of dispersion which is the the second central moment in probability. It is defined as a measure of by how much the values in a data set differs from the mean of the values. Thus it is the average of the squares of the deviations from the mean as this ensures that both the negative and positive deviations do not cancel each other out.
The sample variance would be calculated as follows:
Population size is 7 (5.6 4.9 6.0 5.1 5.5 5.1 7.5)
Mean: Sum of samples / population size ;
(5.6 4.9 6.0 5.1 5.5 5.1 7.5) / 7 = 5.67
Applying the formula for variance: [ Summation (x - mean) ] / population size =( |5.6 - 5.67| + |4.9 - 5.67| + |6.0 - 5.67| + (|5.1 - 5.67|) * 2 + | 5.5 - 5.67| + |7.5 - 5.67|) / 7 = 0.6763 cm^2
M + (119 + m) = the total members in the State Legislature
Step-by-step explanation:
10 -3 10+3*-3= 12 x=10-8=6
According to the questions statements it shows
y= L sin (theta)
and as it shows A and B are right triangle
y= sqrt (L^2 - x^2)
we need to find the speed of B by differentiating w.r.t time.
so,
d/dt = dx/dt . d/dx = -v d/dx
-v represents the A's velocity
so,
Vb = d/dt (y) = -v d/dx sqrt(L^2-x^2)
= v.x/ sqrt(L^2-x^2)
x/ sqrt(L^2-x^2) = cot (theta)
hence
Vb = vcot (theta)
Answer:
You can see that
2
π
radians becomes one revolution when you use the arc length formula:
s

θ
Let
θ
=

. That means:
s
=

r
which is the formula for the full circumference of a circle. Since
2
π
radians is one revolution:
