Answer:0.100324
Step-by-step explanation: Something tells me you are not understanding this subject. I already answered one of your questions similar to this one. Maybe pay attention in class.
Given that the ,mean is 8000 and the standard deviation is 1000, thus the probability that <span>tube lasts for more than 11000 hours. will be given by:
P(x>11000)
the z-score is:
z=(x-</span>μ<span>)/</span>σ
x=11000
μ=8000
σ=1000
hence:
z=(11000-8000)/1000
z=3
thus
P(x>11000)=1-P(x<11000)
But
P(x<11000)=P(z<3)=0.9987
hence
P(x>11000)=1-0.9987=0.0013
The Geometric Mean<span> is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. Below is the solution for the above problem:
</span>First we multiply them: 10 × 1250 = 12,500
Then (as there are two numbers) take the square root: √12,500<span> = </span>111.8034
For question number one, Jovi WILL most likely win.
Hope this helps.
Though we cannot exactly find PT, we can find it in terms of TQ.
Multiply the second equation by 7/6 to get 7TQ/6=7x-7/3. Subtracting 65/3 from both sides, we get 7TQ/6-65/3=7x-24. Since the right side is equal to PT, PT=7TQ/6-65/3.
