Answer:

It's very simple. In 4 decimal digits there are 10,000 (0000 to 9999) possible values. The odds of any one of them coming up randomly is one in 10,000. A specific "4 digit number" would have 1/9000 chance, since there are 9000 4 digit numbers (1000-9999).

Step-by-step explanation:

There are 9,000 true 4 digit numbers and out of that 1000 numbers are divisible by 9.

The probability is given by Favourable Possibilities divided by Total Possibilities.

In the current case, the probability that the number is divisible by 9 is:

1000/9000
1000
/
9000

=1/9
=
1
/
9

The required answer is 1/9

If the clothing maker bought 500 m2 of this fabric, how much money did he lose? Use 1tepiz=0.625dollar and 0.9144m=1yard.
Ivanshal [37]
1 yard^2 = 0.8361m^2.? 

<span>The solution to the problem is as follows:

So he spent (.625 x 400) = $250.00 per m^2. </span>
He paid out (500 x 250) = $125,000 on the deal. 
He received (500 / 0.8361) = 598.014592 yard^2 of fabric. 
That would have cost (598.014592 x 120) = $71,761.75 locally. 
He lost (125,000 - 71,761.75) = $53,238.25 on the deal. 

<span>You can rework with the incorrect conversion factor.

I hope my answer has come to your help. God bless and have a nice day ahead!

At the honda dealership,45% of all cars sold include a sunroof. If this sold 247 cars last week, about how many would you expect
sertanlavr [38]
It is 45% of 247 move the the decimal on the 45% two places to the right, then you should get .45. Of means multiply so .45*247 should get you the answer of 111.15 that's how you find the percent of this number. If you round the answer you would get 111 so about 111cars had a sunroof

What is the value of a?-2(a-8)+6a=36
saul85 [17]
-2(a-8)+6a=36 \\ \\ -2a + 16 + 6a = 36 \\ \\ 4a + 16 = 36 \\ \\ 4a = 36 - 16 \\ \\ 4a = 20 \\ \\ a =  \frac{20}{4} \\ \\ a = 5 \\ \\

The final result is: a = 5.
