The weight of I Tems produced By a machine is normally distributed with a mean of 8 ounces and a standard deviation of 2 ounces. Refer to exhibit 6-5. What is the probability that a radomly selected item will weigh between 11 and 12 ounces

2

step-by-step explanation:

1+1=2

answer: ok

step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

.25
