Identify and correct error
The error is when the inner and outer terms are multiplied. i.e.
not 32x
not 15x
So, the expression is:


they are sot similar because of S and R are not related
Answer:
0.60 cm increase in volume
Step-by-step explanation:
200/Pi(30) = r^2 = 2.12
r = 1.46
400/Pi(30) = new r^2 = 4.24
new r = 2.06
2.06-1.46 = 0.60 cm
Answer:

where x is number of weeks and y is weight in grams.
For this case the y intercept is the value 100 and represent the initial weight for 0 weeks and the best interpretation for this case is given by:
The predicted weight of the rat at birth
And the reason is because the starting value for the weigth represent the weight for the birth
Step-by-step explanation:
For this case we have the following equation given:

where x is number of weeks and y is weight in grams.
For this case the y intercept is the value 100 and represent the initial weight for 0 weeks and the best interpretation for this case is given by:
The predicted weight of the rat at birth
And the reason is because the starting value for the weigth represent the weight for the birth
