Answer:
The equation that models the cost of each bracelet is
Step-by-step explanation:
Let the cost of each bracelet be = x
So, the cost of 8 bracelets are = 8x
The shipping fee is = $6.
The total cost for 8 bracelets, including shipping was $54.
We can denote this mathematically as:
Now solving for x to get the cost of 1 bracelet.
=>
Dividing both sides by 8;
We get x = 6
So, the cost of each bracelet is $6.

Answer:
a) The mean number of radioactive atoms that decay per day is 81.485.
b) 0% probability that on a given day, 50 radioactive atoms decayed.
Step-by-step explanation:
Poisson distribution:
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.
a. Find the mean number of radioactive atoms that decayed in a day.
29,742 atoms decayed during 365 days, which means that:
The mean number of radioactive atoms that decay per day is 81.485.
b. Find the probability that on a given day, 50 radioactive atoms decayed.
This is P(X = 50). So
0% probability that on a given day, 50 radioactive atoms decayed.
a)
his income must be "x" which is the 100%, and we would know that 0.2% of that is 12.37.
b)
his income must be "x" which is the 100%, and we would know that 2% of that is 12.37.
btw he's not making much either way.
