Introduce the following notations of events:
A "The person has the disease"
B "The test is positive", C "the test is erroneous"
Our formula will be then:
So the probability we are looking for is 0.19
<h3>
Answer: C = -4</h3>
==================================================
Work Shown:
C(x+2) - (x+2)(x-2) = 0
(x+2)(C-(x-2)) = 0
(x+2)(C-x+2) = 0
x+2 = 0 or C-x+2 = 0
x = -2 or x = C+2
If we want one solution only, then we must make C+2 = -2 which solves to C = -4
If C = -4, then x = C+2 = -4+2 = -2 which matches with the first solution mentioned. If C is anything else but -4, then we'd have two different solutions (eg: C = 10 leads to x = C+2 = 12 as the other solution)
The oil prices for 2014, rounded to the nearest dollar, were: 95, 101, 101, 102, 102, 106, 104, 97, 93, 84, 76, 59. what is the
kipiarov [429]
- Interquartile Range (IQR) =
, with 
as the upper quartile and 
as the lower quartile.
Firstly, rearrange the data so that it's in ascending order: 
Next, find the median:
Now to find the lower quartile, find the "median" of the data set that's to the left of 99:
Now to find the upper quartile, it's the similar process as finding the lower quartile, except that you are finding the "median" of the data set to the right of 99:
Now that we have the upper and lower quartile, subtract them:
<u>In short, the IQR of this data set is 13.5.</u>
You just have to reverse the operations
1. -48-8= -56
2. -56/3= -18.66
ANSWER = -18.66
Answer:
According to me it is quadratic function.
