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.

a. find the mean of m
b. find the standard deviation of m (assume x and y are independent).

, need accurate solutions

d is correct

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
