Answer:
Step-by-step explanation:
Let
x ----> the number
we know that
The phrase " the phrase: the difference of a number and 9" is equal to
subtract the number 9 from the number x
(x-9)
The phrase" no more than 95" means "less than or equal to 95" (≤95)
so
The inequality that represent this situation is
You can just simplify to make an equivalent equation:
(2)(3x + 8) = 5 ⇒ 6x + 16 = 5

Answer:
There is a 0.82% probability that a line width is greater than 0.62 micrometer.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by
After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X. The sum of the probabilities is decimal 1. So 1-pvalue is the probability that the value of the measure is larger than X.
In this problem
The line width used for semiconductor manufacturing is assumed to be normally distributed with a mean of 0.5 micrometer and a standard deviation of 0.05 micrometer, so .
What is the probability that a line width is greater than 0.62 micrometer?
That is
So
Z = 2.4 has a pvalue of 0.99180.
This means that P(X \leq 0.62) = 0.99180.
We also have that
There is a 0.82% probability that a line width is greater than 0.62 micrometer.
La multiplicación de las fracciones es 2/3
Para multiplicar las dos fracciones tenemos que multiplicar en línea: numerador por numerador y denominador por denominador.
Resolvamos:
Por lo tanto, la multiplicación de las fracciones es 2/3
