Let x = the number of nonzero digits in a randomly selected zip code. what are the possible values of x? (note: u.s. domestic zip codes have exactly five digits with at least two nonzero digits.)
Solution: The possible values of x are 2, 3, 4, 5. Hence the option 2,3,4,5 is correct.
Explanation:
We are given that U.S domestic zip-code consists of 5 digits and there zip-codes contains at least 2 non-zero digits. It means we can not see a zip-code with five zero's and a zip-code with four zero's.
Therefore, we can have zip-code containing 2 non-zero digits, 3 non-zero digits, 4 non-zero digits and 5 non-zero digits. Hence the possible values of x are 2,3,4,5
The answer to your question is 260
You do 2 times the absolute value of 7-7=0 get the answer and do the other side of the equal sign and see if you get the same answer
Answer:
c.1
Step-by-step explanation:
5: 15 x:3
a:b c:d The ratios have to stay in proportion. So if we multiply a and b by a certain number they will equal c and d. We just don't know what that number is yet. Call it something.
a* something = c and b* something =d
5 * something = x
15* something = 3
Solve for the unknown number we are multiplying by
Divide each side by 15
15/15 * something =3/15
something = 1/5
Now that we know what we are multiplying by, we can solve for x
So 5 * something = x
5* 1/5 = x
1 =x
