The probability density function of the length of a metal rod is f(x) = 2.0 for 2.3 < x < 2.8 meters. if the specifications for this process are from 2.25 to 2.75 meters, what proportion of the bars fail to meet the specifications? assume that the probability density function is f(x) = 2.0 for an interval of length 0.5 meters. over what value should the density be centered to achieve the greatest proportion of bars within specifications?

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
