Average = total sum of values/ number of values, so work backwards.
Let x = unknown number.
(18 + 24 + 32 + x)/4 = 24
=74+x = 96
=x=22
She must score 22 in the next game to have an average of at least 24 points.
2x³ + 10x² + 14x + 70 = 2[(x² + 7)(x + 5)]
Actually variation is simply equivalent to the square of
the correlation coefficient r. So we can say that:
variation = r^2
So given an r value of 0.743, so the variation is:
variation = 0.743^2
variation = 0.552
Answer:
55.2%
Volume = ( length x width x height ) / 3
For the pyramid in the picture, it would be ( s x s x h ) / 3
