The slope of this connecting line segment is
-1 - y 1 -(1+y)
m = ---------- = ----- = --------
10-6 4 4
Thus, 4 = -4(1+y), or 4 = -4 - 4y, or -8 = - 4y. y = 2 (answer)
Answer:
r= 8
Step-by-step explanation:
Devide both sides by -4
Answer:
a. The data is skewed left
Step-by-step explanation:
Looking at the graph, the bars are noticeably much taller on the right side when compared to the left.
The mean is likely less than the median, if calculated.
The skewed side of the graph is opposite to what it looks like.
i dont really know sorry
Step-by-step explanation:
X=3, y=3
Solve the following system:
{4 x + 2 y = 18 | (equation 1)
2 x + 3 y = 15 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + 2 y = 18 | (equation 1)
0 x+2 y = 6 | (equation 2)
Divide equation 1 by 2:
{2 x + y = 9 | (equation 1)
0 x+2 y = 6 | (equation 2)
Divide equation 2 by 2:
{2 x + y = 9 | (equation 1)
0 x+y = 3 | (equation 2)
Subtract equation 2 from equation 1:
{2 x+0 y = 6 | (equation 1)
0 x+y = 3 | (equation 2)
Divide equation 1 by 2:{x+0 y = 3 | (equation 1)
0 x+y = 3 | (equation 2)
Collect results:Answer: {x = 3
y = 3
