3 |d + 1 |-7>= -1
I don’t know if it’s no solution or not

Both parts are needed to form the full solution set.

=============================================

Work Shown:

In the second step, I added 7 to both sides. In the third step, I divided both sides by 3. Afterward, I used the rule that breaks down into for some positive value k. The last thing to do is to subtract 1 from both sides to fully isolate d.

1.5%

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
