Answer:
y=7x-48
Step-by-step explanation:
The equation of a line is y=mx+b where m is the slope and b is the y intercept.
To find the slope use the equation Slope=y2-y1/x2-x1
For this equation is is 8+6/8-6=7
I found the y-intercept using the slope and it = -48.
The y-intercept is the point where the line crosses the y-axis.
The answer is 26/7, this cannot be simplified any further
Answer:
k = 9.
Step-by-step explanation:
2x + 3y -8=0
3y = -2x + 8
y = -2/3 x + 8/3
So the slope of this line is -2/3.
Therefore the slope of a line perpendicular to the above is -1 /-2/3
= 3/2.
kx - 6y = 9
6y = kx - 9
y = k/6x - 3/2
But the slope is 3/2,
So k/6 = 3/2
2k = 18
k = 9.
Answer:
Step-by-step explanation:
given that a batch of 140 semiconductor chips is inspected by choosing a sample of 5 chips without replacement.
10 chips do not conform to customer requirements.
i.e. out of 140 chips 10 are defective and 130 are good
a) 5 chips can be selected form 140 chips in 140C5 ways
= 416965528
b) For containing exactly one non conforming chip we have one selected from 10 and other 4 selected from 130
No of ways = 
c) For atleast one nonconforming chip we can calculate as total - no non conforming
i.e.
