Answer:
since the sum of all angles of a triangle is 180°
Step-by-step explanation:
so 100°+4y+25°+3y+20=180°
145°+7y=180°
7y=180°-145°
7y=35°
y=5°
The answer is B because Chris and three of his friends is 4. Then, each person paid $9 so 4 x 3 = x.
Answer:
c. the strength of the relationship between the x and y variables
Step-by-step explanation:
The correlation coefficient refers to the relationship between the two variables
Moreover, it has two mainly correlations i.e
Perfect positive correlation: In this, the correlation coefficient is 1
And, the other is negative correlation: In this, the co
if the correlation coefficient is 1 we have a perfect positive correlation and if the correlation coefficient is -1 than it would be a negative correlation
It lies value between the -1 and 1
hence, the correct option is c.
