Answer:
Hi, I don't see an attachment with your question. But without any attachments to refer to. You use Pyrhagoras Theorem to solve this question.
Step-by-step explanation:
A^2 (Short side) + B^2 (Short side) = C^2 (Long side)

Answer:
predictive value of a positive test = 18.18%
predictive value of a negative test = 94.03%
Step-by-step explanation:
Sensitivity = 60% = 0.6
Specificity = 70% = 0.7
Let True Positive = TP
True Negative = TN
False Negative = FN
Prevalence = 10% = 0.1
Three hundred people are screened,
Total number of people having the disease,
But TP = 1.5 FN
30 = 1.5 FN + FN
30 = 2.5 FN
FN = 30/2.5
FN = 12
TP = 1.5 FN = 1.5 * 12
TP = 18
81 + TN = 270
TN = 189
To calculate the Predictive value of positive test (PPT)
To calculate the Predictive value of negative test (PNT)
Okay so the relationship between points K and K' is that you subtract 4 from the x values and you add 6 to the y values.
1 - 4 = - 3
L ( - 3 , 3 ) ==> L' ( - 3 - 4 , 3 + 6 ) ==> L' ( - 7 , 9 )
The only answer option with L' as such is answer choice B.

Step-by-step explanation:
Area of each paralellogram = b * h = 12 * 20 = 240 square inches
Area of 9 paralellograms = 9 * 240 = 2160 square inches
