90 is the answer. You order the numbers from the lower to the higher and look for the one that gets in the middle ignoring the other numbers.
Using correlation coefficients, it is found that a coefficient of -1 represents a strong negative correlation.
<h3>What is a correlation coefficient?</h3>
- It is an index that measures correlation between two variables, assuming values between -1 and 1.
- If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
- If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
For this problem, we have a correlation coefficient of -1, hence it means that:
- The relation is negative, as -1 is a negative number.
- The relation is strong, as the absolute value of the coefficient is of 1, which is greater than 0.6.

Answer:
Any number above 85.6
Step-by-step explanation:
To calculate the mean you add all of the scores together then divide by how many scores you added
So in this case you would add 84 + 72 + 90 + 87 + 95 = 428
Then you would Divide 428 by five because you are adding 5 numbers
428/5 = 85.6
It says the score increased so as long as then score is greater than 85.6 it is an option.
Answer:
[Distance to the Horizon]^2 =Height of the skydiver x Diameter of the Earth
D^2 = 1.4 x 7918
D^2 = 11,085.2
D = Sqrt(11,085.2)
D = ~ 105.28628......miles - Distance to Horizon.
