Answer:
6 tenths or 0.6, I hope this is what you mean.
Step-by-step explanation:
Answer:
105°
Step-by-step explanation:
The Arc DB = 150°,
If an angle goes from the center of the circle it is the same as the arc. If the angle is inscribed in the circle it is half the arc.
In this case A is inscribed in the circle so its value is half the arc,
The arc is 360 - 150 = 210°
Angle A = 210 / 2 = 105°
We are given the description of a diagram where the base of a parallelogram lies on the x-axis with the left vertex on the origin. We are also given the three consecutive coordinates of the vertices which are
(h, j ), (0, 0), and (k, 0)
Based on the coordinates, the point (h, j) is j units from the y-axis
Let n = required random sample size.
Assume that the population standard deviation is known as σ.
Let m = sample mean.
At the 95% confidence level, the expected range is
(m - k(σ/√n), m + k(σ/√n))
where k = 1.96.
Therefore the error margin is 1.96(σ/√n).
Because the error margin is specified as 3% or 0.03, therefore
(1.96σ)/√n = 0.03
√n = (1.96σ)/0.03
n = 128.05σ²
This means that the sample size is about 128 times the population variance.
Answer:
Smallest sample size = 128.05σ², where σ = population standard deviation.
Replace x and y with the given values and solve the equations:
