Answer:

C. 0.30

The probability is 0.30

Step-by-step explanation:

The diagram used in solving this question is attached.

From the given graph that is attached: the needed region have

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

What equation, in point-slope form, matches the graphed line shown? Question 3 options: y−5=−23(x+9) y−2=−34(x−6) y+6=45(x+3) y−

ziro4ka [17]

Step-by-step explanation:

the line passes through (6, 2) and (10, -1),

the slope =

(-1-2)/(10-6) = -3/4

the equation :

y-2 = -3/4(x -6)
