Answer:
x = 5.25
Step-by-step explanation:
If I am understanding the question correctly, you are asking to find x when 4x=21? If this is the case, then all you must do is divide 21 by 4, then you get 5.25.
Answer:
y = 7
Step-by-step explanation:

Add -4y and 6y

Move all terms not containing y to the right side of the equation.

Divide both sides by 2

Answer:
B) -0.98
Step-by-step explanation:
Correlation coefficient is usually denoted with numbers ranging from 1 to -1. Automatically, this eliminates option C) as our possible answer, since -1.43 is outside the range.
The trend shown in the scatter plot describes a negative relationship because, as the values in the Y-axis decreases, the values at the X-axis increases. The possible correlation coefficient we are likely to get is one that is negative. This eliminates option A and option and option D is our possible correlation coefficient for the scatter plot given since both values are positive.
Option B) -0.98, best represents the correlation coefficient of the given scatter plot. Since the points on the scatter plot seem closely aligned on a straight line, a negative value if -0.98 is mostly the possible one to get.
1. A

3. C
4. A
I’m not so sure about number 4 tho!!
