We will be using the fact that , where is the probability that the first bulb works and is the probability that the second bulb works.
The probability that the first bulb works is . However, when we take one out (given that the first bulb works) we now have 19 working bulbs and 4 bad ones. This means that the probability that the second bulb works is .
Now, we can find our final probability:
Answer:
The equation of a line in the slope-intercept form is:
y = 5x - 18
The slope-intercept form of the line equation
where
m is the slope
b is the y-intercept
In our case, we are given
m = 5
Point (4, 2)
now substituting m = 5 and (4, 2) in the slope-intercept form of the line equation to determine the y-intercept
y = mx + b
2 = 5(4) + b
20 + b = 2
subtract 20 from both side
20 + b - 20 = 2 - 20
b = -18
now substituting b = -18 and m = 5 in the slope-intercept form of the line equation
y = mx + b
y = 5x + (-18)
y = 5x - 18
Therefore, the equation of a line in the slope-intercept form is:
y = 5x - 18
Pls mark me as brainliest thank you
Answer: x = (-2,0) y = (0,-3) slope is -3/2
Step-by-step explanation: graph the line by using the slope and y intercept
Answer:
Step-by-step explanation:
Income = 12h - 4.5c
h = 8
c = 2
Income = 12*8 - 4.5*2
Income = 96 - 9
Income = 87
I = let
I= 300*.06*.5
I= $9.00
Since time in the formula is years and the money was not in for a complete year you have to use the part of the year (6months) that it was earning interest 1/2 year or .5
