Answer: D -10 - 12
Step-by-step explanation:
Temperature change is (Final T) - (Initial T)
(Final T) = -10C
(Initial T) = 12
(Final T) - (Initial T) = -10C - 12C
Temp Change - 22C
You would circle the 3 in 31, the 9 in 94, and the 1 in 17
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
