Answer: $15
Step-by-step explanation:
8 cookies cost $12 you divide 12 by 8 and then you get 1.5 which equals 1.50 so each cookie is 1.50. So for 10 cookies you multiply 10 times 1.50 and you get your answer $15. 10 cookies cost $15
Answer:
- 9 < t < 5
Step-by-step explanation:
Isolate | t + 2 | by subtracting 4 from both sides
| t + 2 | < 7
Inequalities of the type | x | < a always have a solution of the form
- a < x < a, hence
- 7 < t + 2 < 7 ( subtract 2 from all 3 intervals )
- 9 < t < 5
Answer:
Poisson distribution.
Step-by-step explanation:
We have the mean number of missing pulses per disk, which means that the distribution for X, the number of missing pulses, will be the Poisson distribution.
It is not the binomial distribution because we are not given the probability of a missing pulse on a disk, but the mean number of missing pulses.
