Correlation coefficients whose magnitude are between 0.3 and 0.5 indicate variables which have a low correlation.<span> Correlation coefficients whose magnitude are less than 0.3 have little if any (linear) correlation.</span>
Answer:
Step-by-step explanation:
a) Standard deviation of 10 mean the fluctuation for values range from +10 to -10 from the mean.
b) Since the sixth student is 50 minutes, which is higher than the mean of 45 minutes, this will bring the over all mean higher that 45 minutes. Also, since 50 falls within the standard deviation range (35 to 55), this mean the new standard deviation will be smaller than 10.
A =
bh Multiply both sides by 2 to cancel out the fraction
2A = bh Divide both sides by b
= h Switch the sides to make it easier to read

h = </span>
It is a acute triangles because the degrees are less than 90 degrees
The answer is negative 32
