I need help with number 4

Ainat [17]

There actually isn't anything to 'work'. There's no question there.

The function simply describes the relationship between two numbers.

It says that whatever you pick for the first number, the second number is

(-4 times the square of the first one) plus (7 times the first one) plus (6) .

Your teacher may have assigned you something to do with the function,
like draw the graph of it, or find its maximum value (2.9375), or find where
it crosses the x-axis (2.381 and -0.63) or the y-axis (6).

But we can't tell what you've been assigned to do with it. The function alone,
just as you've posted it, isn't asking a question, and doesn't call for any work.

The range of which function is (2,infinity)

sergeinik [125]

I don't have any pictures of graphs but a function that has a range of (2, infinity) means that hte lowers point (lowest y-value) is 2, and the height function keeps increasing (the y-value keeps increasing) to infinity.

someone please help :( a sample of the amount of rent paid for one-bedroom apartments of similar size near the University of Ore

Volgvan

Answer:

Oregon:

Median: 467.5

Mean: 451.33

Standard Deviation: 113.6

Washington:

median: 380

Mean: 396.6

Standard deviation: 56.3

Step-by-step explanation:

To calculate the median, we need to organize the price and select the value that is in the middle position.

To calculate the mean, we need to sum all the values and divide them by the number of values

To calculate the standard deviation, we need to square the distances between every price and the mean, sum it all and divide them by the number of values less 1 and finally calculate the square root.

So, for Oregon, the organized values are:

$295, $345, $460, $475, $538, $595

The median is a value between $460 and $475. it is calculated as:

$\frac{460+475}{2}=467.5$

The mean is:

$\frac{295+475+345+595+538+460}{6}=451.33$

The standard deviation is:

$\sqrt{\frac{(295-451.3)^2+(475-451.3)^2+(345-451.3)^2+(595-451.3)^2+(538-451.3)^2+(460-451.3)^2}{6-1}}=113.6$

At the same way, we can calculate the median, mean, and standard deviation for Washington and get:

median: 380

Mean: 396.6

Standard deviation: 56.3
