Answer:
Step-by-step explanation:
We know by definition that the cosine is an even function, therefore
We also know that the sin is an odd function, therefore
By definition:
Then:
Using these trigonometric properties we can simplify the expression
Answer:
Option D is correct.
Step-by-step explanation:
We have been given the rate is raised by $45
Since, if we increased mean by 45 there will be no change in number of observations and in sum because there is symmetry in the sum of observations.
So, mean will be increased by $45
And standard deviation will remain same because it means how far the term is from the mean.
Therefore, option D is correct.
Answer:
tex]Both \: the \: moon \: and \: earth \: are \: in \: \\ the \: shape \: of \: spheres. \\ Surface\: area \: of \: a \: sphere \: of \: radius \: 'r' \\ [/tex]
Let d1 be the diameter of the moon and d2 and be the diameter of the earth.Let r1 be the radius of the moon and r2 be the radius of the earth.
