Achemical supply company ships a certain solvent in 10-gallon drums. let x represent the number of drums ordered by a randomly chosen customer. assume x has the following probability mass function: x 1 2 3 4 5 p(x) 0.4 0.2 0.2 0.1 0.0 a. find the mean number of drums ordered. b. find the variance of the number of drums ordered. c. find the standard deviation of the number of drums ordered. d. let y be the number of gallons ordered. find the probability mass function of y. e. find the mean number of gallons ordered. f. find the variance of the number of gallons ordered. g. find the standard deviation of the number of gallons ordered.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
