To answer this question, we have to follow the next steps:
1. Subtract 13 to both sides of the equation:

2. Divide the resulting equation by 5 to both sides of the equation:

Therefore, the value that solves this equation is W = 21/5 or W = 4.2 (using a decimal expression.)
42.44inches if the radius is 3 ( I think it’s 3 as it’s the only other number )
The range rule of thumb is that the range is four times the standard deviation. The range in this case is 922 cubic cm to 1496 cubic cm, i.e., 574 cubic cm.
Therefore, according to the rule, the standard deviation is 574 cubic cm/4 =
143.5 cubic cm. The actual standard deviation is 161.7 cubic cm. The difference is 161.7 - 143.5 = 18.2. Since this is greater than 15 cubic cm, the rule in this case is not accurate.
A) 3n+4= 7n
B) 4n-5= -1n
You do a normal equation just add the N
