Answer: E) Even with a correlation value of 0.94, it is possible that the relationship could still be better represented by a nonlinear model.
Step-by-step explanation:
The correlation Coefficient of 0.94 obtained is peculiar to the linear model upon which the data was represented. Since the correlation Coefficient usually span between - 1 to + 1, it is very possible that, if the dataset is represented on a different model such as an exponential or quadratic model, the correlation percentage obtained may be better than that produced by the linear model.
The probability that a region prone to hurricanes will be hit by a hurricane in any single year is one tenth or 0.1
P(at least one) = 1 - P(none in five years)
-----
= 1 - 0.90^5
= 1 - 0.59049
=0.40951 or 0.41.
41% probability that there will be a hurricane at least once in the next 5 years.
Answer: 1.25 each
Step-by-step explanation:
50-30 = 20
20 divided by 16 = 1.25
