Step-by-step explanation:
hello :
Ax + 3x = bx + 5
Ax + 3x-bx = bx-bx + 5
x(A+3-b) =5
x= 5/(A+3-b)
Answer:
Step-by-step explanation:
60 guests are there with 10 circular tables of 6 seats each.
First we have to select 6 persons from 60 for I table and next 6 persons for II table etc.
i.e.first table can be assigned 6 people in 60C6 ways
II table from remaining 54 in 54C6 ways
....
Each table with 6 persons can be arranged in a circular table in 5! ways
(since Two seating arrangements are considered the same if the person to the left of each person is unchanged)
Thus no of ways of allotting persons to different tables
= 60C6*54C6*48C6*42C6...*6C6
Each table allotment is in (6-1)! = 5! ways
Total ways of seating arrangement =
25.8%
First, determine how many standard deviations from the norm that 3 tons are. So:
(3 - 2.43) / 0.88 = 0.57/0.88 = 0.647727273
So 3 tons would be 0.647727273 deviations from the norm. Now using a standard normal table, lookup the value 0.65 (the table I'm using has z-values to only 2 decimal places, so I rounded the z-value I got from 0.647727273 to 0.65). The value I got is 0.24215. Now this value is the probability of getting a value between the mean and the z-score. What I want is the probability of getting that z-score and anything higher. So subtract the value from 0.5, so 0.5 - 0.24215 = 0.25785 = 25.785%
So the probability that more than 3 tons will be dumped in a week is 25.8%
Answer:
x= 3, y= -2
Step-by-step explanation:
5x+3y= 9
x= 25÷7 + 2÷7 y
5(25÷7 +2÷7 y)
5( 25÷7 +2÷7 y ) + 3y= 9
y= -2
x= 25÷7 + 2÷7 x (-2)
x= 3
