Which equations can be used to solve for y, the length of the room? Check all that apply. y(y + 5) = 750 y2 – 5y = 750 750 – y(y
Alex777 [14]
Let's assume length of the room as y
so the width of the room = y - 5

Area
y * (y - 5) = 750

A coordinate grid with 2 lines. One line, labeled f(x) passing through (negative 3, 3), (0, 3), and the point (4, 3). The other
Lyrx [107]

Answer:

x = 4

Step-by-step explanation:

It is stated that f(x) passes through

(-3, 3), (0, 3), (4, 3)

and g(x) passes through

(-4, -3), (0, 0), (4, 3)

Therefore, both functions pass through (4, 3). That is, the input value x = 4 produces the same output value y = 3 for the two functions.

Answer:

P(\bar X

And we can use the following z score:

z = \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}

And replacing we got using the normal standard distribution table or excel:

P(\bar X

C.0.8413

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

Solution to the problem

Let X the random variable that represent the records of a population, and for this case we know the distribution for X is given by:

X \sim N(76,12)  

Where \mu=76 and \sigma=12

Since the distribution for X is normal then we know that the distribution for the sample mean \bar X is given by:

\bar X \sim N(\mu, \frac{\sigma}{\sqrt{n}})

We select a sample of size n=36, and we want to calculate this probability:

P(\bar X

And we can use the following z score:

z = \frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}

And replacing we got using the normal standard distribution table or excel:

P(\bar X

C.0.8413
