Answer:
x = 19
Step-by-step explanation:
These angles are supplementary angles which mean they add up to 180:
8x - 7 + x + 16 = 180
9x + 9 = 180
9x = 180 - 9
9x = 171
x = 171/9
x = 19
Answer:
The scale factor is 2/3.
Step-by-step explanation:
Given data,
The given image is (6,9)
The image after dilation is (4,6)
The scale factor is calculated by dividing the resultant image by the initial image.
For example, if the initial dimensions are (x1, y1) and the final dimensions are (x2,y2). The scale factor is calculated using x2/x1 = y2/y1 = Scale Factor
In our scenario,
x1 = 6
x2 = 4
y1 = 9
y2 = 6
Scale Factor = x2/x1
=> 4/6
=> 2/3
Similarly for y axis,
Scale Factor = y2/y1
=> 6/9
=> 2/3
Therefore, the scale factor is 2/3.
Answer:
n=6
So then the correlation coefficient would be r =0.913
And as we can see the value for r is very high and near to 1. so the correct option for this case would be:
C. There is a positive correlation between the heights of men and women.
Step-by-step explanation:
Previous concepts
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
And in order to calculate the correlation coefficient we can use this formula:
We have the following data:
Women (X): 66 64 66 65 70 65
Men(Y): 72 68 70 68 74 69
We have quantitative data so no makes sense say that we have categorical data.
For our case we have this:
n=6
So then the correlation coefficient would be r =0.913
And as we can see the value for r is very high and near to 1. so the correct option for this case would be:
C. There is a positive correlation between the heights of men and women.
