Let angle HAC = A, then
cos A = 24/25 = 0.96
A = cos^-1(0.96) = 16.26
In an Arithmetic sequence, the difference between two consecutive terms of the sequence remains the same. This difference is known as common difference.
If we observe the given options, we can note:
In option A, the difference between two consecutive terms is the same and is equal to 1.
In option B, the difference between two consecutive terms is the same and is equal to -2.
In option C, the difference is not the same.
In option D, the difference between two consecutive terms is the same and is equal to 5.
In option E, the difference is not the same.
So, the correct options are A,B and D
The correlation coefficient represents the strength of a relationship of two sets of data relative to how linear they are. A correlation coefficient of r = 1 would indicate that the relationship was perfectly linear, a correlation coefficient of 0 would mean that they have absolutely no relationship linearly, and are completely dispersed. Hope that makes sense! :) :D
He was 21 in 1980,
There are twelve years in between them all so you subtract 36 from 78 and since he was double as old as Nancy, and Manual was the same age as her, you would divide 42 into two parts, Ric and the 10.5 year olds, and Ric would be 21 in 1980.
