1/9 - (-2/5 - 8/9) = 1/9 + 2/5 + 8/9 = 1 + 2/5 = 7/5 or 1 2/5
Hello,
Answer (1-√5,0) , (1+√5,0)
Indeed,
S=(1,20)
==> y=k*(x-1)²+20
(0,16) is a point of the parabola
==>16=k*(0-1)²+20==>k=-4
Parabola: y=-4(x-1)²+20
if y=0 then -4(x-1)²+20=0==> 4(x-1)²=20=> (x-1)²=5 ==> x=1+√5 or x=1-√5
In a random sample of students at a middle school 24 wanted to change the mascot and 30 wanted to keep the current mascot.
So total number of students in the sample = 30+24= 54
Number of students in random sample who wanted to keep the current mascot = 30
So out of 54 students 30 wanted to keep current mascot.
So for 1140 students = (30/54)*1140 = 633 students want to keep the currect mascot.
Answer: Third option 633 students.
