galben [10]

In 5 years it grew 6 mill (181-175=6). Formula: 6(20/5)+181=X. multiply 6 by 4 (the number of five years in twenty years): 24. 24+181=205 million :)

The nba regulations require the basketball court to be 132 feet long. How many meters is length of the Court.??? Thank you!!!

Natalija [7]

Answer:

40.23 meters (rounded to 2 decimal places)

Step-by-step explanation:

We need to convert 132 feet to meters by using the conversion factor shown below:

1 feet = 0.3048 meters

Now we can setup a ratio to solve for the length of basketball court in meters (let it be x). Shown below:

$\frac{1}{0.3048}=\frac{132}{x}\\x=132*0.3048\\x=40.2336$

Thus, length of basketball court (in m) = 40.23 meters (rounded to 2 decimal places)

In a standard Normal distribution, if the area to the left of a z-score is about 0.3500, what is the approximate z-score? Dr

wlad13 [49]

Answer:

z-score=0.385

(See attached picture)

Step-by-step explanation:

The procedure to find the z-score will depend on the resources we have available. I have a table with the area between the mean and the value we wish to normalize, so the very first thing we need to do is precisely find this area we need to analyze.

Everything to the left of thte mean will represent 50% of the data, so we start by subtracting:

50%-35%=15%

so we need to look in the table for the value 0.15.

In my table I can see that for an area of 0.15, the z-score will be between 0.38 (z-score of 0.1480) and 0.39 (z-score of 0.1517).

By doing some interpolation, you can determine a more accurate value of the z-score to be 0.385.
