Answer:
y=-1/2x-1/2
Step-by-step explanation:
For this, you need to use the point slope formula, (y-y1)=m(x-x1). The slope, m, would be -1/2 since the line we're looking for is perpendicular (meaning the slope is the negative reciprocal of the original slope). The x1 would be 3, and the y1 would be 1.
(y-y1)=m(x-x1)
(y-1)=-1/2(x-3)
y-1=-1/2x-3/2
y=-1/2x-1/2

Answer:
The surface area of the candle is
Step-by-step explanation:
we know that
The surface area of the candle is equal to the area of its triangular base plus the area of its three lateral triangular faces
so
Answer:
Step-by-step explanation:
Given
--- proportion
--- defective motors
--- sample size
Required
Determine the probability that exactly 2 is defective
This follows a Poisson distribution and will be solved using:
Where
u = Expected number of occurrence, and it is calculated as:
So:
becomes
<em>Hence, the probability that exactly 2 out of 60 will be defective is 0.2613</em>
40 because 180-60=120 and 120 divided by 3 is 40.
