Answer:
<h2>g(f(x)) = x² - 3</h2>
Step-by-step explanation:
f(x) = x²
g(x) = x - 3
In order to find g(f(x)), substitute f(x) into g(x), that's for every x in g(x) replace it with f(x)
We have
g(f(x)) = x² - 3

why are you asking these easy questions? I thought your math level was way out.
The answer is at least or more than 39 square feet
Answer:
The probability that the proportion of passed keypads is between 0.72 and 0.80 is 0.6677.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes <em>n</em> > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:

The standard deviation of this sampling distribution of sample proportion is:

Let <em>p</em> = the proportion of keypads that pass inspection at a cell phone assembly plant.
The probability that a randomly selected cell phone keypad passes the inspection is, <em>p</em> = 0.77.
A random sample of <em>n</em> = 111 keypads is analyzed.
Then the sampling distribution of
is:

Compute the probability that the proportion of passed keypads is between 0.72 and 0.80 as follows:


Thus, the probability that the proportion of passed keypads is between 0.72 and 0.80 is 0.6677.
It looks like the 45
What I did was add the 60+30=90 then subtract from 180 and divided my 2 and got 45 hopes this helps!
