Answer:

C. 0.30

The probability is 0.30

Step-by-step explanation:

The diagram used in solving this question is attached.

height = 0.5

width = 124.7 - 124.1 = 0.6

The area of the rectangular region is:

= l * b\\= 0.6 * 0.5\\= 0.3

Therefore, the probability of a random voltage between 124.1 and 124.7 is 0.3

Answer:

x= -6

Step-by-step explanation:

-2x-14=-2

We move all terms to the left:

-2x-14-(-2)=0

We add all the numbers together, and all the variables

-2x-12=0

We move all terms containing x to the left, all other terms to the right

-2x=12

x=12/-2

x=-6
