Answer:$33.41
Step-by-step explanation:
I converted the percentages to decimals and subtracted them from 1.
(Btw x stands for the cost before tip and tax)
This was the equation I came up with based on what was given to me;
57.29 = (1-0.085)x + (1-0.2)x
57.29=0.915x + 0.8x
57.29=1.715x
Divide both sides by 1.715 and should get 33.40524781
Since we are rounding to the nearest cent, the answer would be $33.41
Answer: 60
Step-by-step explanation: See photo.
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.
