Answer:
You will have 21 positive results.
Step-by-step explanation:
Sensitivity of test:
Is the true positive rate, that is, the proportion of positive results that give positive tests.
Specificity of test:
True negative rate, that is, the proportion of negative results that give negative tests.
90% sensitive, 20 reliable people apply
0.9*20 = 18
95% specific, 60 unreliable people apply
1 - 0.95 = 0.05 of positive results.
0.05*60 = 3
How many positive results will you have?
18 + 3 = 21
You will have 21 positive results.
Multiply length times width to find the area. 6.5x11= 71.5
7n -12 = -32 + -3n
I think this is the equation
Answer:
20
Step-by-step explanation:
using the rule of logarithms
loga + logb = logab
then
4 +
5
=
(4 × 5)
=
20
The answer is 2/15.
4x1=4
10x3=30
Simplified by dividing 2 on both side to get 2/15
