Answer:
The solution to the given system of equations is (-2,
)
Therefore the values of x and y are x=-2 and 
Step-by-step explanation:
Given equations can be written as
Solving equation(2) we get
x=-2
Substitute x=-2 in equation (1) we get
Therefore the values of x and y are x=-2 and
The solution to the given system of equations is (-2,)
Answer:
a) 0.7403
b)0.0498
c)0.2240
Step-by-step explanation:
Given: The number of surface flaws in plastic panels used in the interior of automobiles has a Poisson distribution
We know that to calculate expected number of flaws use
expected number of flaws =10×0.03 =0.3
a) probability that there are no surface flaws in an auto's interior =P(X=0)=
e^-0.3 =0.7408
b) probability that none of the 10 cars has any surface flaws =(e^-0.3)^10 =0.0498
c) probability that at most one car has any surface flaws =P(X<=1)=P(X=0)+P(X=1)
this means
=10C_0(1-0.7408)^0(0.7408)^10+10C_1(1-0.7408)^1(0.7408)^9=0.2240
A step function, as it decreases once every 15 days and remains constant for periods in between.
