The efficiency of sample information a. is the EVSI/(maximum EMV without SI) expressed as a percentage. b. is the EVPI/EVSI expressed as a percentage. c. would be 100% if the sample information were perfect. d. is computed using only the EVPI and the maximum EMV.

c. would be 100% if the sample information were perfect

Step-by-step explanation:

EvSI is the expected value of sample information while EVPI is the Expected Value Perfect Information

The efficiency of a sample is simply the ratio of the Expected value of Sample Information to the Expected Value of Perfect Information

it is between 0 and 1

a. is the EVSI/(maximum EMV without SI) expressed as a percentage is not true

b is the EVPI/EVSI expressed as a percentage. is also not true as the efficiency is the EVSI/EVPI ex[pressed as a percentage

d. is computed using only the EVPI and the maximum EMV. is also not true, we have to calculate EVSI from EMV .

\C. is correct, would be 100% if the sample information were perfect.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
