Answer:
0.9155
Step-by-step explanation:
As, the random variable X the number of accident follows the Poisson distribution so,
P(X=x)=(μ^x)(e^-μ)/x!
μ=average accident=4.1.
The probability that more than one accident occurs per year= P(X>1)=?
P(X>1)=1-P(X≤1)
P(X>1)=1-[P(X=0)+P(X=1)]
P(X=0)=(4.1^0)(e^-4.1)/0!
P(X=0)=0.016573/1
P(X=0)=0.016573
P(X=1)=(4.1^1)(e^-4.1)/1!
P(X=1)=(4.1)0.016573/1
P(X=1)=0.0679481
P(X>1)=1-[0.016573+0.0679481]
P(X>1)=1-0.084521
P(X>1)=0.915479
P(X>1)=0.9155
The probability that more than one accident occurs per year is 91.55%
Answer:
E
Step-by-step explanation:
Since all the numbers are hundredths decimals, let multiply by the power of 2 of the base 10. So let multiply the equation by
So our new equation is
Solve by AC method
We must think of two numbers that
Multiply to -462 and Add to 71. Set up equation
The numbers are 77 and -6.
So our new equation is
Solve by factoring by grouping
Factor out 11 for the first equation
So our factors are
Set each equal to zero
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
-3x-2y=2
step 1
Find the y-intercept
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0
-3(0)-2y=2
-2y=2
y=-1
The y-intercept is the point (0,-1)
step 2
Find the x-intercept
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0
-3x-2(0)=2
-3x=2
x=-2/3=-0.667
The x-intercept is the point (-0.667,0)
step 3
Find the third point
For x=2
substitute
-3(2)-2y=2
-6-2y=2
-2y=8
y=-4
The third point is (2,-4)
step 4
Plot the points and graph the line
see the attached figure
Note Just two points was enough to draw the line.
Answer:
1. The y-intercept 8 means you start off with $8. The slope 1/4 means how much money you have to pay for the amount of tickets purchased for carnival games.
2. The y-intercept 2 means the number of chapters you started reading and the slope 5/4 means the number of chapters you read per day.
3. The y-intercept 3 means the inital (start) cost of a muffin delivery and the slope 2 means the cost of each muffin delivery for the number of muffins you ordered.
Number 3 on the slope part might be the other way around if I'm wrong :)
