Answer:
7x
Step-by-step explanation:
We can factor out x and simplify.
4x +3x = x(4 +3) = 7x
Y=-3x+-1. you subtract (-4)-(-1) =3 and 1-0 and you get 1 . so the slope is 3 over 1 . and the y intercept is -1
Answer:
Step-by-step explanation:
The total number of claim is the sum S of 1250 independent random variables,
each having poisson distribution with mean μ = 2
Since the Variance of poisson distribution is equal to its mean ,
the standard deviation of this is
By the CLT is follow that S is approximately normal with mean 1250*2 =2500
and standard deviation
Hence, the probability to compute is
(2,13) is a solution to the equation y=3x+7.
The two equations have the same slope, and so are parallel.
