1. 5 is a solution to the inequality

2. 8 is a solution to the inequality

3. q=20 is a possible solution to the inequality

4. t=28 is not a possible solution to the inequality

Step-by-step explanation:

1.

1+f<7

subtract 1 from both sides of the inequality;

f<7-1

f<6

The value of f should therefore be strictly less than 6. From the alternatives given only the number 5 meets this condition and is thus a solution to the inequality.

2.

g-3>4

add 3 to both sides of the inequality;

g>4+3

g>7

The value of g should therefore be strictly greater than 7. From the alternatives given only the number 8 meets this condition and is thus a solution to the inequality.

3.

q-2>16

add 2 to both sides of the inequality;

q>16+2

q>18

The value of q should therefore be strictly greater than 18. Consequently, q=20 is a solution to the inequality since;

20>18

4.

t-7<10

add 7 to both sides of the inequality;

t<10+7

t<17

The value of t should therefore be strictly less than 17. Consequently, t=28 is not a solution to the inequality since;

28 is not less than 17.

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%
