Answer:
0.9704 = 97.04% probability of getting a cookie with at least 3 chips
Step-by-step explanation:
We only have the mean number of chocolate chips. So we use the Poisson distribution to solve this question.
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 time interval.
A well-mixed cookie dough will produce cookies with a mean of 7 chocolate chips apiece.
This means that
What is the probability of getting a cookie with at least 3 chips?
Either we have less than 3 chips, or we have at least 3 chips. The sum of the probabilities of these events is decimal 1.
We want . Then
In which
0.9704 = 97.04% probability of getting a cookie with at least 3 chips
Answer:
Ronald
Step-by-step explanation:
RONALD:
Cups of sugar = 2
Cups of flour = 5
Cups of sugar / cup of flour mixed = 2/5 = 0.4 per cup
MADELYN :
Cups of sugar = 6
Cups of flour = 16
Amount of sugar per cup of flour :
Cups of sugar / cup of flour mixed = 6/16 = 0.375 per cup
RONALD'S cake is sweeter, it has greater amount of sugar per cup than madelyn's
Remember, to be a function, all elements in the domain should correspond to one element in the range.
The domain is the x coordinate, range is the y coordinate.
The domain we can solve for as the set {4.2, 5, 7}. The range is the set {0, 1.5, 2.2, 4.8}.
But we see that an element in the domain corresponds to more than one element in the range, thus making it not a function.
