Answer:
what school?
Step-by-step explanation:
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:
The slope is -2
Step-by-step explanation:
(0,4) (3,-2)
remeber the equation is Y2-Y1/X2-X1
Y2 = -2
Y1 = 4
X2=3
X1=0
Plug it in the euqation to see if it works
The average speed would be 53 miles per hour, hope this helped, if you need me to explain then here is the way, so all you do is divide 265 by 5 and what I did to help make it faster was split 265 into 250 and 15 so 250 divided by 5 is 50 and 15 divided by 5 is 3 so 50 + 3 = 53!
-4y = 8x
y = 8x/-4
y = -2x
The constant of variation is -2
