Answer:
The probability is 
Step-by-step explanation:
Let assume that the number of computer produced by factory C is k = 1
So From the question we are told that
The number produced by factory A is 4k = 4
The number produced by factory B is 7k = 7
The probability of defective computers from A is 
The probability of defective computers from B is 
The probability of defective computers from C is 
Now the probability of factory A producing a defective computer out of the 4 computers produced is

substituting values


The probability of factory B producing a defective computer out of the 7 computers produced is

substituting values


The probability of factory C producing a defective computer out of the 1 computer produced is

substituting values


So the probability that the a computer produced from the three factory will be defective is

substituting values


Now the probability that the defective computer is produced from factory A is



(0, 36) would be the point on the y axis, so 36 is the y-intercept, or the b value in the equation, y = mx + b.
(12,0) is the x-intercept, so we know the line has a negative slope.
The equation for these points would be:
y = -3x + 36

Step-by-step explanation:
A particular satellite is 15 m wide
Model of it was built with a scale of 1 cm: 5 m
=> scale of the model will be: 1/500cm and A particular satellite is 1500 cm wide
=>1500*1/500=3(cm)
