YO I NEED HELP ON THIS 100 POINTS Q1: In order to complete the factoring by grouping process, what must you have before you can GROUP terms? Why is it important?

Q2: How do you approach finding the Greatest Common Factor (GCF)?

Q3: How can you check your answer after factoring?

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

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
