Answer:
x = 8
y = 7
Step-by-step explanation:
x • 6 = 48
In order to isolate the variable, you need to do the opposite operation which is division in this case.
Divide 6 by 6 to cancel it out. Whatever you do to one side has to be done to the other side. Now we're left with 48 ÷ 6
We can check this by plugging your answer in the equation
8 • 6 = 48
This statement is true
y • 7 - 1 = 48
Start with doing the inverse operation, which is addition. Add 1 to -1 to cancel it out and do the same to the other side
y • 7 = 49
Then, divide 7 by 7 and do the same to the other side
y = 7
Check to make sure you're right
7 • 7 - 1 = 48
49 - 1 = 48
48 = 48
This statement is true
I hope this helps. (:
Answer:
The probability that occurrence of 8 in ten minutes is 0.0771.
Step-by-step explanation:
Poisson Distribution:
A discrete random variable X having the enumerable set {0,1,2,.....} as the spectrum, is said to have Poisson distribution with parameter (>0), if the p.m.f is given by
for x=0,1,2,...
= 0, elsewhere
The mean number of occurrences in ten minutes is 5.3.
Here = 5.3 and x= 8
=0.0771
The probability that occurrence of 8 in ten minutes is 0.0771.
