Fifty dived by half minus of forty what is the answer?

Step-by-step explanation:

50÷1/2-40

50×2-40

100-40

60

the answer is 60

60

Step-by-step explanation:if the equation is 50/.5-40, the first step is to turn them into fractions 50/1 and 50/100 (or 1/2) then you flip the second fraction and change the sign to multiply so it would be 50/1x2/1.

Y=50/.5-40

Y=50/1x2/1-40

Y=100-40

That leaves you with 100/1 (or 100). Then you subtract 40 from 100

100-40=60

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
