Nine times d = 9*d = 9d

47 decreased by 9d = 47 - 9d

= 47 - 9d.

Complete the table below.

N76 [4]

Answer:

column 1, (2 and 2)

column 2, (8 and 4)

Step-by-step explanation:

For the first one, y = 2 $x^{2}$ . You would plug in 1 into x and since one times itself is one, you would end up with 2. For the next question, you would plug in one and find that two times one is two. For the next column, by plugging in 2, you would find that you would end up with 2 times 4 and thus, you would find the answer which is 8. Lastly, two to the power of two is 4. Hope this helped!

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

weeeeeb [17]

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.
