The total cost would be $191.49
Not rounded up so round it up to .50 if you have to :)
Answer: Not correct
Step-by-step explanation:
If you plug 3 in for x and 7 in for y and solve you figure out there not equal. -1=-2(3)+7
-2(3)+7=1 because -2x3 is -6 and -6+7 is 1 which means -1=1 which isn’t true
Answer:
a) 0.0081975
b) 0.97259
Step-by-step explanation:
The line width for semiconductor manufacturing is assumed to be normally distributed with a mean of 0.5 micrometer and a standard deviation of 0.05 micrometer
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation.
a. What is the probability that a line width is greater than 0.62 micrometer?
z = 0.62 - 0.5/0.05
z = 2.4
Probability value from Z-Table:
P(x<0.62) = 0.9918
P(x>0.62) = 1 - P(x<0.62)
= 0.0081975
b. What is the probability that a line width is between 0.4 and 0.63 micrometer?
For 0.4
z = 0.4 - 0.5/0.05
= -2
Probability value from Z-Table:
P(x = 0.4) = 0.02275
For 0.63
z = 0.63 - 0.5/0.05
= 2.6
Probability value from Z-Table:
P(x = 0.63) = 0.99534
P(x = 0.63) - P(x = 0.4)
= 0.99534 - 0.02275
= 0.97259
c. The line width of 90% of samples is below what value?
Answer: The Answer is 26
Step-by-step explanation: Well, I first divided 3 by 4 and then I got 1 and then I did 1 + 23 and got 24 and then 3 made even is 2 so I added 2 and got 26!
