I asked this before and the person said there was no data....i submitted the data in one picture and question in the second image! this is literally all of the information i have! that's why i am asking for help!!!
Use the formula
density=mass/voulme
Density is decreasing because mass is slightly increased but volume is increasing in a significant number upon marble added

- I am curious if someone could check these answers for me? I believe they turned out incorrect and am curious to see what I need to do to fix them. Thanks!Answer is provided. All I need is the solution. Thank you! A patient cuts 100-mg scored tablets to take his 50-mg prescribed daily dose. A prescription for thirty 100-mg tablets costs $45, and a prescription for thirty 50-mg tablets costs $40. The patient asked the pharmacist to weigh an uncut tablet on an electronic balance into two “halves.” The uncut tablet was found to weigh 240 mg, and the cut “halves” weighed 125 mg and 115 mg, respectively. (a) How much money did the patient save on a monthly basis by dosing with half-tablets? (b) What was the percentage error in the weight of the cut tablets compared with “exact halves”? Answer: (a) $17.50 (b) 4.2%You measure 35 turtles' weights, and find they have a mean weight of 72 ounces. Assume the population standard deviation is 3.1 ounces.

Use the 68-95-99.7 Rule to determine the number of observations in the data set expected to be above a value of 107. Round your answer to the nearest whole value. Hint: This problem is asking for how many observations not the percent. Answer Tip: Don't round any probabilities or percentages in your calculations. Keep all decimal places and round at the END of the problem.
