Answer:
P(1≤X≤3) = 0.5974
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Mean of 3
This means that
P(1≤X≤3) ?
So
So
Answer:
r = 5.696 and θ = 157.17°.
Step-by-step explanation:
the point is (-5.25,-2.21). The distance from the point to the origin is calculated with the formula
r = 5.696 m.
I drew the point and the distances in the plane. to find te angle we can use the sin formula:
sin(θ) =
θ = .
within the range of -180° and 180° the angle will be θ = 180-22.83 = -157.17°
The answer is D. the data shows a positive linear association.
Answer:
x-intercept(s): (0,0)
y-intercept(s): (0,0)
Step-by-step explanation:
To find the x-intercept(s), substitute in 0 for y and solve for x
0 = -x
To find the y-intercept(s), substitute in 0 for x and solve for y
y = -(0)
