Answer:
One can be 95% confident that the drive-through service times of fast-food chain is between 169 seconds and 172 seconds.
Step-by-step explanation:
The confidence interval gives a range of value for the population mean or parameter, which is calculated from the statistic value of the data (that is sample statistic). This range gives the interval which is associated with a certain level of confidence for which the interval will contain the true value of the unknown parameter (true value). In the scenario above, the associated confidence level is 95%.Hence, we can be 95% confident that the true value will be continued with the interval (169 ; 172)
Answer:
The system of inequalities is as follows:
30x + 20y ≥ 61,000
x ≤ 1500
x + y ≤ 2800
x ≥ 0
y ≥ 0
Step-by-step explanation:
The system of inequalities can be explained as follows:
30x + 20y ≥ 61,000 <= Indicating a take in of at least $61,000 in ticket sales.
x ≤ 1500 <= Indicating that 500 reserved seats are available.
x + y ≤ 2800 <= Indicating limit of the paid ticket holders to 2800.
x ≥ 0 <= Indicating ticket x must be equal or greater than 0.
y ≥ 0 <= Indicating ticket y must be equal or greater than 0.
Answer:
12
Step-by-step explanation:
if you divide 156 students into 13 cabins you divide it into equal groups, once you divide all of it to equal groups you get 12 students in each cabin.
So, 52-24=28. That means that the remaining books are nonfiction books. 28 is the answer.
