Answer:
0.4082
Step-by-step explanation:
Given that the number of customers received by a drive-through pharmacy on Saturday mornings between 8:00 AM and 9:00 AM has a Poisson distribution with λ (Lambda) equal to 1.4.
X has Poisson mean=1.4
the probability of getting at least 2 customers between 8:00 am and 9:00 am in the morning
=![P(X\geq 2)\\=0.4082](https://tex.z-dn.net/?f=P%28X%5Cgeq%202%29%5C%5C%3D0.4082)
Required probability = 0.4082
1.solve for d under 1 can't type that means it wants d1= so
A= 1/2 d1d2
Mult by 2/1 of each side you get
2A= 1/2times 2/1 d1d2
2A= d1d2
Divide by d2 on both sides the d2 cancel on the right
2A/d2= d1
d1= 2A/d2
2.V=LWH
Divide by LH
V/LH= LWH/LH. LH cancel
V/LH= W
Hope this helps You and mom
7. -4x+y=9
Bring the 4x to the right makes it positive
Y= 4x+9
9. -3y+18x=12
-3y= -18x+12
Divide by -3 all of it
Y= 6x-4
Answer:
There could be many but one of them is
(m+5)(m-9)=0....
Answer:
a) μ =35.858KN
b) median cable strength =36.06KN
Step-by-step explanation:
Let X1, X2, X3, X4 represent the strength of the 4 wires.
We can find the median of the cable strength in minitab as:
Stat - Basic statistics- Display descriptive statistics-variable (C5) -statistics(median) - ok
Median cable strength is 36.06 KN
Therefore the estimate of the mean strength of the cable is 35.858 KN, and the estimate of the median cable strength is 36.06 KN.
