What’s the solution of y= 3x-1 and y= 3x+4
julia-pushkina [17]

Step-by-step explanation:

solution ? you mean where both lines cross each other ?

these are 2 parallel lines (same slope, but different y-intercept), so they never cross each other.

there is no solution.

formally :

3x - 1 = 3x + 4

-1 = 4

this is wrong. therefore there is no solution.

3.- In a certain desert region the average number of persons who become seriously ill each year from eating a certain poisonous
Naily [24]

Answer:

P(X\geq 5)=1-P(X

Using the pmf we can find the individual probabilities like this:

P(X=0)=\frac{e^{-6.4} 6.4^0}{0!}=0.001662

P(X=1)=\frac{e^{-6.4} 6.4^1}{1!}=0.010634

P(X=2)=\frac{e^{-6.4} 6.4^2}{2!}=0.034029

P(X=3)=\frac{e^{-6.4} 6.4^3}{3!}=0.072595

P(X=4)=\frac{e^{-6.4} 6.4^4}{4!}=0.116151

And replacing we got:

P(X \geq 5) =0.76493

Step-by-step explanation:

Previous concepts

Let X the random variable that represent the number of people that will become sereiosly ill in two years. We know that X \sim Poisson(\lambda)

The probability mass function for the random variable is given by:

f(x)=\frac{e^{-\lambda} \lambda^x}{x!} , x=0,1,2,3,4,...

And f(x)=0 for other case.

For this case the value for \lambda would be:

\lambda = 3.2 \frac{ills}{year} *2 years = 6.4

For this distribution the expected value is the same parameter \lambda

E(X)=\mu =\lambda

On this case we are interested on the probability of having at least two chocolate chips, and using the complement rule we have this:

P(X\geq 5)=1-P(X

Using the pmf we can find the individual probabilities like this:

P(X=0)=\frac{e^{-6.4} 6.4^0}{0!}=0.001662

P(X=1)=\frac{e^{-6.4} 6.4^1}{1!}=0.010634

P(X=2)=\frac{e^{-6.4} 6.4^2}{2!}=0.034029

P(X=3)=\frac{e^{-6.4} 6.4^3}{3!}=0.072595

P(X=4)=\frac{e^{-6.4} 6.4^4}{4!}=0.116151

And replacing we got:

P(X \geq 5) =0.76493
