Answer:
(d.) Those who score high on one variable tend to score low on the other.
Step-by-step explanation:
A negative value of correlation coefficient (r) shows a relationship between two variables such that as one variable increases, the other decreases. It shows the inverse relationship between two variables with the dependence determined by the value of the correlation coefficient (r).
It can be observed that for graphs with negative slope, the correlation coefficient (r) is similarly negative. This speaks about its relationship too.
The correlation coefficient being negative doesn't mean the relationship between the two variables in question is bad, it just means that the correlation relationship is inverse (still dependent). A perfectly negative correlation is -1.
Answer:
C) 33 meters
Step-by-step explanation:
In this question, we need to find the value of the variable "x".
To do this, we must use the Pythagorean theorem: a² + b² = c²
Plug in your values and solve:
56² + b² = 65²
3,136 + b² = 65²
3,136 + b² = 4,225
Subtract 3,136 from both sides.
b² = 1,089
To cancel out the exponent, we would square root both sides.
√b² = √1,089
b = 33
This means that C) 33 meters will be your answer.
Answer:
D
Step-by-step explanation:
the theoretical probability is a fancy term for an even amount of both, which would be 20 flips landing on H, and 20 landing on T. Since the question is asking what's the difference between the theoretical probability and the experimental results, you'd take 20(theoretical number of flips that land on H) and subtract 15 (experiment results for the amount of flips that land on H), and 20 - 15 = 5. Now that you know the difference is 5, you would divide 5 by 40 to find the answer. 5/40 = 1/8 when you simplify, making the answer D.
