Numbers from zero to nine are individually selected at random and combined to make a code that contains a six-digit number. Numb

ers can be repeated. If you were given ten tries to guess the code what would be the probability of guessing the correct code? Give you answer as a fraction. Do not include commas in your answer, for example, 31,000 would be written as 31000.

Answer:

The probability of guessing the correct code is \frac{1}{100000} ,  If you were given ten tries to guess it.

Step-by-step explanation:

First of all, we need to find the total possible combinations due the code is composed by numbers from zero to nine are individually selected at random and combined to make a code that contains a six-digit number. So we obtain \# of\ possible\ combinations=10^{6}=1000000.

Then, as we have ten tries to guess, \frac{\# of\ tries}{\# of\ possible\ combinations} =\frac{10}{1000000}=\frac{1}{100000}, is the probability of guessing the correct code, one out one houndred thousand.

Use the number line to show and explain why 4/10 ÷ 2 and 4/10 × 1/2 both equal 2/10
Vesna [10]

Step-by-step explanation:

When you divide by a number, you basically are multiplying by the reciprocal

The reciprocal of 2 is 1/2

4/10 ÷ 2 = 4/10 × 1/2 = 2/10

4/10 × 1/2 = 2/10

Using a number line,

Start at 4/10 and move down by 2 until you reach 0

Start at 4/10 and move up by 1/2 from 0 until you reach 4/10

(Count the number of humps)

Both will be the same

Colt1911 [192]
What is the exact question? It seems like you are asking for the Pythagorean theorem. Ok, I’ll try to help if that’s the case.

a^2 + b^2 = c^2
4^2 + 5^2 = c^2
16 + 25 = c^2
41 =c^2
6.403124237432849 = c

So now since we have the answer, we need to figure out if this result and 6 are equal.

6^2 = 36

25 + 16 = 41

41 and 36 are not equivalent so if the case is that u want me to find the Pythagorean theorem, then the answer is that they aren’t equal. And the real answer is that c equals 6.403124237432849. Which means that 4in, 5in, 6in is not the correct order. And that 16in, 25, 41 is the correct order.

I hope this helped!
