We assume that the problem above involves right triangles, wherein the diameter of the moon would be the height and the distance from Earth would be the base. By finding the desired angle, we used the tangent function:
tan (theta) = 2160 / 238860
theta = tan -1 *( 2160 / 238860) = 0.516 degrees
Therefore the angle in the eye of the beholder would be half a degree.
Answer:
3r+5
Step-by-step explanation:
Since -5r and 8r both have r in them, we can combine them and the expression looks like:
3r+5
Which is our answer.
Diagonals of a rhombus
In any rhombus, the diagonals (lines linking opposite corners) bisect each other at right angles (90°). That is, each diagonal cuts the other into two equal parts, and the angle where they cross is always 90 degrees.

Answer:
(c)
(b) The probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c) The probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
Step-by-step explanation:
The random variable <em>X</em> follows a Uniform (25, 35).
(a)
The probability density function of an Uniform distribution is:
Then the probability density function of the random variable <em>X</em> is:
(b)
Compute the value of P (X > 33) as follows:
Thus, the probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c)
Compute the mean of <em>X</em> as follows:
Compute the probability that cooking or preparation time is within 2 mins of the mean time as follows:
Thus, the probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
