Answer:
$30.
Step-by-step explanation:
70/28 = 2.5
12 x 2.5 = 30
Answer:
-16
Step-by-step explanation:
By using a scatter plot we can get the relationship of two variables or correlation.
There will be two types of correlation.
If the data of the plot show a positive slope of the estimated line then it will be a positive correlation.
Now a correlation value lie between 0 to 1 if it is very close to 0 like 0.1 , 0.2 then we can say the correlation is weak psitively correlated. and if it will be close to 1 like 0.8 or 0.9 then the correlation will be strong.
Similarly if slope of the estimated line will be negative then it will be a negative correlation.
From the above scatter plot notice that it has a negative slope and we can draw a fair estimate line on this scatter plot. So, there is strong negative correlation.
Hence the correct choice is -0.8.
Answer:
x = -8/5
Step-by-step explanation:
-3(x+4) -> -3x-12
-3x-12=7x+4
-7x
-10x-12=4
+12
-10x=16
16/-10 = -8/5
-8/5 = x
