Can someone please help me?

Step-by-step explanation:

1:   26000

2: 20500

3: nicholas

1. 25,000+1000x

2. 19,000+1500x

3. 25000+1000x>19000+1500x

Step-by-step explanation:

For the 1st it is 25,000 because that is what he starts off with and there is an x behind 1000 because it depends on how many years he receives the bonus. For example, if he was there for 3 years the equation would look like 25000+1000(3).  

For the 2nd one, it is the same concept as the first one.

For the third one, it says that Nicholas will make more money so the greater symbol has to be facing the equation that stands for his amount of money.

Hope this helps!

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
