75,88,90,96,98,100
minimum = 75
Q1 = 88.....this is where the box begins
Q2 (the median) = (90 + 96) / 2 = 186/2 = 93....this is the line in the box
Q3 = 98....this is where the box ends
maximum = 100

Answer:
0.02 inches per minute
Step-by-step explanation:
1 Week = 10080 minutes
Formaul: multiply the time value by 10080 to find the minutes in a week or do it the long way 60x24x7 = 10080
230/10080 = 0.02281746031 or 0.02 rounded to nearest hundert.
Imagine a cake. OK? Now divide the cake in 2 equal pieces, each one is ½ of the cake.
Now divide each piece in 2 halves; each one is ¼ of the cake. Witch is largest? 1:2=0,5; 1:4=0,25. 0,5>0,25.
5:6=0,83333
29:36=0,80555
0,83>0,80 so 5/6 is the largest.
Do this for each group.
a.5/6
b.5/8
c.19/45
d.13/14
e.7/11
f.1/2
Answer:
The probability that the next failure will not occur before 30 months have elapsed is 0.0454
Step-by-step explanation:
Using Poisson distribution where
t= number of units of time
x= number of occurrences in t units of time
λ= average number of occurrences per unit of time
P(x;λt) = e raise to power (-λt) multiplied by λtˣ divided by x!
here λt = 25
x= 30
P(x= 30) = 25³⁰e⁻²⁵/ 30!
P (x= 30) = 8.67 E41 * 1.3887 E-11/30! (where E= exponent)
P (x=30) = 1.204 E31/30!
Solving it with a statistical calculator would give
P (x=30) = 0.0454
The probability that the next failure will not occur before 30 months have elapsed is 0.0454
