Javier works in a photo lab and needs to make a reduced copy of a photograph that is 8 inches long. the customer wants the copy to have a length of 4.5 inches. each time he presses the reduce button on the copier, the copy is reduced by 12%. javier and his boss had an argument, because javier claimed that pressing the button 5 times would be enough to fulfill the customer's request. his boss said that pressing the button 5 times would result in a length less than the desired 4.5 inches. which of the following conclusions can be made?

Javier should not press the button five time.

Step-by-step explanation:

The given scenario says that Javier claimed that pressing the button 5 times would be enough to fulfill the customer's request. So, lets check that.

We will start at 8 inches.

Press once, inches.

Pressing again, we get inches.

Again pressing we get inches.

Again we get inches.

Again we get inches.

We can clearly see here that pressing 4 or 5 times does not get 4.5 inches exactly as claimed by Javier.

Therefore, Javier claim is not right and his boss is right.

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
