PLEASE ANSWER I'M DESPERATE

a coffee dispenser is supposed to pour out 16 ounces of coffee. the machines are not entirely perfect, since the standard deviation is .3 ounces. assume you test the machine and pour 50 cups of coffee, and come up with a sample mean of 15.8 ounces. what is the probability that you would get a result of 15.8 or lower?

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
