Answer:
74%
Step-by-step explanation:
Multiply both the numerator and denominator by 2 so that you will have a number over 100. After doing this you will have 74/100 which is 74%
Answer:
The time the patient expected to survive after diagnosis is 29 years.
Step-by-step explanation:
It is provided that the mean survival time after diagnosis for a certain disease is 15 years with a standard deviation of 5 years.
That is,
![\mu=15\\\sigma=5](https://tex.z-dn.net/?f=%5Cmu%3D15%5C%5C%5Csigma%3D5)
An individual's predicted survival time is <em>a</em> = 2.8 standard deviations beyond the mean.
Compute the time the patient expected to survive after diagnosis as follows:
![X=\mu+a\sigma](https://tex.z-dn.net/?f=X%3D%5Cmu%2Ba%5Csigma)
![=15+(2.8\times 5)\\\\=15+14\\\\=29](https://tex.z-dn.net/?f=%3D15%2B%282.8%5Ctimes%205%29%5C%5C%5C%5C%3D15%2B14%5C%5C%5C%5C%3D29)
Thus, the time the patient expected to survive after diagnosis is 29 years.
Hello :
<span>7x-2y=1 ...(1)
2y=x-1...(2)
</span><span>substitution 2y in (1) :
</span>7x-(x-1) = 1
7x-x+1 = 1
7x = 0
x=0
in (2) : 2y = 0-1
2y = -1 y= -1/2
the <span>system have one solution : (0 ;-1/2)</span>
