Measurements are made on the length and width (in cm) of a rectangular component. because of measurement error, the measurements are random variables. let x denote the length measurement and let y denote the width measurement. assume that the probability density function of x is
f(x) = 10 for 9.95 < x < 10.05
f(x) = 0 for otherwise
and that the probability density function of y is
g(y) = 5 for 4.9 < y < 5.1
g(y) = 0 for otherwise

assume that the measurements x and y are independent. find p(x < 9.98)

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

its 50 miles away from the starting point

sorry man i accidentally pressed yes my bad

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
