Answer:
90 students.
Step-by-step explanation:
Given that Cho surveyed a random sample of 60 students in the school's library, of which 15 said they read the newest magazine, and that a total of 360 students attend the library every day, to determine how many of the 360 students can have expect to read the newest magazine the following calculation should be performed:
60 = 100
15 = X
15 x 100/60 = X
1,500 / 60 = X
25 = X
Thus, 25 percent of the students in the sample read the newest magazine. Since 25% of 360 is 90 (360 x 0.25), that is the number of students he can expect to have read the magazine.
Answer:
C. 17.9
Step-by-step explanation:
First you have to find the area of the circle, to then subtract it from the area of the square around it.
To get the area of the circle you must take the radius(half of the diameter) and square it. 3^2 is 9. Then you mutiply that by Pi( 3.14). Which is 7.07.
Next you have to subtract that from the area of the square deck.
25-7.07=17.9
