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.)0, 1, 2, 3, , 2, 3, 4, 0, 1, 2, 3, 4, 52, 3, 4, 5

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

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
