In a study of births from New York State, data were collected from 4 hospitals and coded as follows: (1) Albany Medical Center (

nalin [4]

Answer:

No. See the explanation below.

Step-by-step explanation:

No makes sense.

For this case the codification used is just a notation to identify the hospital. No matter if the code is a numerical value not makes sense calculate the average for these numbers since that not represent any statistic useful for the study.

And the other reason why is not appropiate calculate the mean of these numbers is that if we calculate the mean we don't have a maning for this number since we can't say the mean for the codes is (a number) since that's irrrelevant for the study.

15. Find the value of x and y rounded to the nearest tenth. X 34 45° 30° y

Ugo [173]

Answer:

x = 24.0

y = 46.4

Step-by-step explanation:

Let opposite side = z

Using trigonometry :

Sin 30 = z / 34

z = 0.5 * 34

z = 17

We find x :

Sin 45 = 17 / x

x * sin45 = 17

x = 17 / sin 45

x = 24.04

Let y = y1 + y2

y1 = 17 / tan45

y1 = 17

y2 = 17/tan30

y2 = 29.44

y = 17 + 29.44

y = 46.44

Assume that all (525)poker hands are equally likely. What is the probability that you will be dealt:

AlekseyPX

Answer:

There is 1.98% of probability of being dealt a flush in 5-card Poker

Step-by-step explanation:

To know the probability of a flush being dealt, we can calculate the number of cases when that happens and divide it by the total number of cases of poker hands that exist, naming A the event of a flush.

We will use combinations (nCr button on a calculator) to count the number of cases, because we don't care about the order (it is the same to be dealt a 2, 4, 6, 7 and 8 of hearts than the opposite order), being a flush the event when we take 5 cards out of 13 of the same suit, times 1 out of 4 possible suits and the total number of cases is taking 5 random cards out of 52.

$P_{A} =\frac{Cases Of Flush}{Hands} =\frac{\left(\begin{array}{ccc}13\\5\end{array}\right)*\left(\begin{array}{ccc}4\\1\end{array}\right)}{\left(\begin{array}{ccc}52\\5\end{array}\right)} =\frac{5148}{2598960}=0,00198\\$

That means there is about a 2% of probability of being dealt a flush.

In other words, of every 16660 plays, 33 will be, on average, a flush
