Answer:
Sheet metal costs <u>$20</u> per square foot.
Step-by-step explanation:
7.6x - 2.3x = 106
We are finding the value of x.
5.3x = 106
Divide both sides by 5.3.
x = 106 ÷ 5.3
x = 20
See tha attached pdf file and let me know how useful this answer is.
The <em><u>correct answer</u></em> is:
She can determine that while there is an association between the variables, there is no correlation, and she cannot determine causation.
Explanation:
Since there is an arch shape to her graph, we know that as one variable changes, the other changes in the same manner. This means there is an association between the variables.
However, since the graph is not linear, there is no correlation between the variables. Since there is no correlation, we cannot determine causation.
Answer:
0.1x+0.15(50-x)= 50*0.12
Step-by-step explanation:
50 ml of 12% solution has 50*0.12 ml of alcohol
x ml of 10% solution has x*0.1 ml of alcohol
(50-x) ml of 15% solution has (50-x)*0.15 ml of alcohol
The equation to solve is:
