Answer:
3=95 vertically opposite angle
2+95=129 exterior angle is equal to the sum of two opposite interior angle of a triangle
2=129-95=34 answe
4+3+47=180 sum of interior angles of a triangle is 180
4=180-47-95=38 answer
Step-by-step explanation:
Answer:
r = 0.99
Very strong positive correlation between x and y
Step-by-step explanation:
Given is a data containing years and the corresponding heights
We have to find the correlation coefficient.
x y
1 2.1
2 3.2
3 6.8
4 7.3
5 11.2
6 12.6
7 13.4
8 15.9
r 0.988670694
Formula for r is
Thus we find that correlation coefficient is 0.988670694
Rounding off to two decimals r = 0.99
Very strong positive correlation between x and y
Answer:
70
Step-by-step explanation:
Let's say something multiplied by 60 = 4,200
We will represent something with Y
Then,
Y × 60 = 4,200
60Y = 4,200
Divide both sides by 60, then we'll have
60Y/60 = 4,200/60
Y = 4,200/60
Y = 70
Therefore, the other factor is 70
