First answer is -5.
Second answer is -1.
The correlation coefficient (r) is a number that describes how closely the numbers in the data set are related. The correlation coefficient will always be between −1.0 and +1.0. If the correlation is positive, there is a positive relationship. If it is negative, the relationship is negative. If the two are not correlated at all, the correlation coefficient will be 0. Strong and weak correlations are a little more subjective in that there is no exact cutoff between strong and weak, but generally, any r value that is close to either 1 or negative 1 is considered strong. Any value of r that is closer to 0 is considered weak.
Since the y-intercept is -3, plot a point at -3 on the y-axis (vertical). Then, continue to make points by following the slope down.
Remember, slope is written as y/x
A slope of -1/2 could be interpreted as -1 over 2. So, each time you move down 1 space, you move to the right 2 spaces.
So, following the slope down, you'd plot another point at (2,-4). Then, another at (4,-5), and so on. Understand?
Answer:
D. 20 yds
Step-by-step explanation:
✔️First, find the distance across across the pond on the drawing using Pythagorean Theorem:
Distance across = √(6² + 8²) = √100
Distance across on drawing = 10 in.
✔️Next, find the actual distance using the scale of 1 inch : 2 yards:
The scale implies that,
1 inch represents 2 yards
Therefore:
10 inches will represent = 10 × 2 = 20 yards
