Answer:
We are 95% sure that the true mean number of alcoholic beverages consumed per week by the population of all US college students is between 3 and 6.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
95% confidence interval is between 3 and 6.
This means that we are 95% sure that the true mean number of alcoholic beverages consumed per week by the population of all US college students is between 3 and 6.
In this item, we are to supply for the missing term on one side of the equation. The left side is given to be composed of 62.834 x 0.45. The right hand side is given to be composed of 314170 along with a missing entity.
Translating the given to mathematical expression and letting A be the unknown,
62.834 x 0.45 = 314170 A
To determine the value of A, divide both sides of the equation by 314170.
(314170A)/(314170) = (62.834 x 0.45) / 314170
A = 0.00009
The missing value is 0.00009 or 9.0 x 10^-5.

Answer:
The taxi charges $2.5 for every mile.
Step-by-step explanation:
We are given the following in the question:
Let x be the initial taxicab fare and y be the additional amount for every mile traveled.
Cost for a two mile ride = $7.00
Thus, we can write the equation:
Cost of a nine mile ride = $24.50
Thus, we can write the equation,
Solving the two equation by elimination method, we have,
Thus, $2 is the initial fare and $2.5 is the cost for every mile traveled.
