Answer:
c. 64% of the variation in the weight of luggage is explained by the number of passengers
Step-by-step explanation:
The explained variance is a measure given by the coefficient of determination, R².
The value Given above is the correlation Coefficient, R, which is 0.8
The Coefficient of determination, R² = 0.8² = 0.64, expressing as a percentage ; 0.64 * 100% = 64%
This means that 64% of the variation in the dependent variable is can be explained by the regression line. (independent variable)
Answer: For every 7 centimeters it equals 1 meter. So if there is 5 meters, you would mulitiple 5 by 7 to get 35 centimeters and the same in vice versa. I hope this helps!!!!

According to the given, 1 in every 10 women has been a victim, therefore the probability of a victim of domestic abuse at some pint is
We need to use Binomial distribution to take a randomly sampled of 25 women and asked each whether she has been a victim.
Where x is the event that shows a victim of domestic abuse at some point.
We need to find the probability of these victim at least 2 has been victim of abuse, so
So the probability is 0.729
