The following table shows the results of a medical test. Has diseaseDoes not have disease

Use the preceding data to estimate the specificity for that test. (Round your answer to one decimal place.)

The sensitivity of the test is 0.9

Step-by-step explanation:

The given information are;

                            Has disease,                              Does not have disease

Test positive,         180                                               40

Test negative,        29                                                400

Where:

True Positive    = TP = 180

False Positive   = FP = 40

False Negative = FN = 29

True Negative =  TN = 400

Sensitivity = TP/(TP + FN) = 180/(180 + 29) = 0.861

The sensitivity for the test is 0.861 which is 0.9 to one decimal place.

the answer is simply just 6n add the two together as they have an n

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
