The molarity of a solute in solution is defined to be the number of moles of solute per liter of solution (1 mole = 6.02 × 1023 molecules). if x is the molarity of a solution of magnesium chloride (mgcl2), and y is the molarity of a solution of ferric chloride (fecl3), the molarity of chloride ion (cl−) in a solution made of equal parts of the solutions of mgcl2 and fecl3 is given by m = x + 1.5y . assume that x has mean 0.125 and standard deviation 0.05, and that y has mean 0.350 and standard deviation 0.10.

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
