Answer:
The number of Girls players in the Team of 18 players is 6 .
Step-by-step explanation:
Given as :
The total number of player including boys and girls = 18
And times girls player + times boys player = 7
Let The number of boys player = B
The number of girls player = G
So, According to question
G + B = 18 ...1
× G + × B= 7
or, + = 7 ...2
or, Put the value of B from eq 1
or, + = 7
Or, - + 6 = 7
or, = 7 - 6
Or, = 1
∴ G = 1 × 6 = 6
Hence The number of Girls players in the Team of 18 players is 6 . Answer
x = 0.17(repeating 7) (1st)
10x = 1.77 (2nd)
subtract (1st) from (2n)
9x = 1.77 - 0.17
9x = 1.6
90x = 16
x = 16/90
x = 8/45
answer
8/45
Answer:
-4
Step-by-step explanation:
Answer:
495 ways
Step-by-step explanation:
We solve this above question busing the combination formula
C(n,r) = nCr
= n!/(n - r)! × r!
We are told in the question that:
A textbook search committee is considering 12 books for possible adoption the committee has decided to select 8 of the 12 for further consideration
C(12, 8)
n = 12
r = 8
12C8 = 12!/8! × (12 - 8)!
= 12!/8! × 4!
= 495 ways
Answer:
<h3>after 2 secs</h3>
Step-by-step explanation:
The paths crossed at when the height are equal i.e when f(x) = g(x)
Given
f(x)=−x^2+2x+4
g(x) = 2x
IF f(x) = g(x), then;
−x^2+2x+4 = 2x
−x^2+2x+4 - 2x = 0
−x^2+4 = 0
-x^2 = -4
x^2 = 4
x = ±√4
x = 2 and -2
Time cannot be negative
Hence x = 2
The path crossed after 2 seconds
