Answer: D.
The y-intercept of the line means that the weight of the empty jar is about 160 grams.
Step-by-step explanation:
We know that the equation of line is given by , where m is the slope of the line and c is the initial amount .
For the given linear equation
where x is the number of marbles added, and y (dependent variable ) is the weight of the jar.
Slope of line m= 4.95 which is approximately 5 , thus, for every increase in marble, weight of jar increased by approx 5 gram.
To find the y intercept , put x=0, we get
y=160.03 which means if there is no marble then the weight of the jar = 160.03 grams or approximately 160 grams.
Thus, The y-intercept of the line means that the weight of the empty jar is about 160 grams.
All of the centra angles in a regular polygon must add up to 360 degrees. Also, because you're told that it is a regular polygon, the "regular" indicates that all of the central angles will be the same. Divide 360 degrees by 18 degrees to get the number of central angles, which is the same as the number of sides. 360/18 = 20. Therefore, the polygon has 20 sides. Hope that helps!
