Answer:
Option C is the answer.
Step-by-step explanation:
To find the equation of the straight line equation i.e, we must be given with the two points 
and 
Since from the graph the two points closest to the line are
and 
Equation of line with two points closest to the line :
where m is the slope.
First we find the slope(m)=
on simplify we get, 
.
Now, to find the equation of the line:
Apply distributive property on right hand side, we get
Adding both sides by 36, we get
.
The equation for the linear model in the scatter plot obtained by the two closest point 
closest to the line is,
Answer:
C
Step-by-step explanation:
It's the only one where an x-axis has more than one y-axis.
I hope this explanation helps.
You have to do the opposite
22-17=5
5x3=15
15+13=28
28/4=7
The answer is 7. You can check this by doing what it says and if it makes 22, it’s correct. (I’ve already checked it) :)
Answer:
The total weight of the metal bar in pounds is 25 pounds
Step-by-step explanation:
Now, we have a metal bar which has a content of 60% zinc corresponding to 15 pounds.
Mathematically, let’s say the total weight of the metal composite is x pounds. It is 60% of this that is 15 pounds which is the content of the zinc
Mathematically;
60/100 * x = 15
60x = 15 * 100
60x = 1500
x = 1500/60
x = 25 pounds
