The midpoint between y and k is d. What is y?

Which score has a higher relative position, a score of 271.2 on a test for which = 240 and , or a score of 63.6 on a test for wh

Fittoniya [83]

Answer:

The score of 271.2 on a test for which xbar = 240 and s = 24 has a higher relative position than a score of 63.6 on a test for which xbar = 60 and s = 6.

Step-by-step explanation:

Standardized score, z = (x - xbar)/s

xbar = mean, s = standard deviation.

For the first test, x = 271.2, xbar = 240, s = 24

z = (271.2 - 240)/24 = 1.3

For the second test, x = 63.6, xbar = 60, s = 6

z = (63.6 - 60)/6 = 0.6

The standardized score for the first test is more than double of the second test, hence, the score from the first test has the higher relative position.

Hope this Helps!!!

Answer:

The initial fee for the ticket is 3.5 dollars

Step-by-step explanation:

For 4 stops, the price of a ticket is 8 dollars

For 8 stops, the price of a ticket is 14 dollars.

- The number of stops increased in this case is: 8 -4 = 4 stops

When there are more 4 stops, the price of a ticket also increase from 8 to 14 dollars => the increase in price is: 14 - 8 = 6 dollars.

Similarly, for 8 stops, the price of a ticket is 14 dollars.

For 12 stops, the price of a ticket is 20 dollars.

- The number of stops increased in this case is: 12 - 8 = 4 stops

When there are more 4 stops, the price of a ticket also increase from 14 to 20 dollars => the increase in price is: 20 - 14 = 6 dollars.

So that, the price for an extra stop is constant and equal to: 6/4 = 1.5 dollars

=> The price for 3 extra stops is: 1.5 x 3 = 4.5 dollars

For 4 stops, the price of a ticket is 8 dollars

=> The initial fee for the ticket = 8 dollars - The price for 3 extra stops = 8 - 4.5 = 3.5 dollars.
