Answer:
4/1 or 4
Step-by-step explanation:
when graphing perpendicular lines, the slopes are reciprocals of eachother
Answer:
n=
v
------------------
1.047198r2
Step-by-step explanation:
Step 1: Flip the equation.
1.047198nr2=v
Step 2: Divide both sides by 1.047198r^2.
1.047198nr2
1.047198r2
=
v
1.047198r2
n=
v
1.047198r2
Answer: C
Step-by-step explanation:
When there is division inside a set of parentheses, you can distribute the power to each term. When you take a power to another power, you multiply the powers.
-5 x -4 = 20
-2 x -4 = 8
So your answer is:

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.
