Answer:
t=-7u+70/0
Step-by-step explanation:
Since you have just 3 vertices here, I'm assuming that your figure is a triangle. What are you supposed to do? Please share all of the instructions.
So first you plug 2 in for t
4(2.72)^(-2/2)
4/2.72 (because the simplified exponent is -1)
divide and that's your answer.
Next you plug 1 in for t
4(2.72)^(-1/2)
4/sqrt(2.72) (because -1/2 as an exponent is 1/sqrt(x))
plug that into a calculator and that's your answer
For c, you plug 1 in for V(t).
1=4(2.72)^(-t/2)
1/4=2.72^(-t/2)
Here is where I get stuck because I haven't done logarithms in a year and forget how to do them but I know that's what you have to do for this problem.
In the last problem you plug x in for V(t) and I'd assume go about solving it the same as c. Sorry I couldn't be of more help.
Answer:
0.3174
Step-by-step explanation:
Given that a manufacturer makes integrated circuits that each have a resistance layer with a target thickness of 200 units
These thickness measurements, X, are approximately normally distributed with a mean of 200 units and a standard deviation of 12 units.
Sample size n = 16
Sample mean will follow N(mu = 200, std error = 12/sqrt 16)
i.e. 
: N(200, 3)
Required probability
= probability that the mean thickness in these 16 measurements xˉ is farther than 3 units away from the target value
= 
This should be the answer. Hope this helps
