Of 400 students
No of girls = 0.45 x 400= 180
No of Boys = 400-180=220
Of the. No of boys 30% are football players =0.30 x 220 = 66
Answer:
whatever
Step-by-step explanation:
the first quartile is between 34 and 36 = 35
the third quartile is between 45 and 47 = 46
2(n+3)= 4
n= -1
-1+3=2 then 2x2=4. Sum is an answer to an addition problem so a number and 3 times 2 = 4. Hope this helps and have a great day!
We'll start by calling the number of pigeons we started with x, because it's the unknown.
After she clapped 1/3 flew away so she was left with
(1 - 1/3) x = (2/3) x
Two flew back, so now there are
(2/3) x + 2
She clapped again and half left, half stayed, so now
(1/2) ( (2/3) x + 2 )
One came back and there were five,
(1/2) ( (2/3) x + 2 ) + 1 = 5
Solving is unraveling.
(1/2) ( (2/3) x + 2 ) = 4
(2/3) x + 2 = 8
(2/3) x = 6
x = (3/2) 6 = 9
Answer: 9 pigeons
Check: Reviewing the story, 9 -> 6 -> 8 -> 4 -> 5 good
