I'm not quite sure if I'm right because i am barely learning that but the answer would be
2sec²θ
idk sorry.. hope the answer is right.
80% Add up the marbles. 10 marbles. Divide the total amount of marbles by the number of blue and red marbles. That should equal 20%. That would be the probability of drawing a black marble. So, 80% is the answer

Answer: x = 37 and y = 11
Explanation:
Let x be the bigger number
Let y be the smaller number
x + y = 48
But x is 7 less 4 times the smaller number.
=> x = 4y - 7
Substitute this value of x:
4y - 7 + y = 48
5y = 48 + 7
5y = 55
y = 11
Substitute the value of y in to the equation:
x + 11 = 48
x = 48 - 11
x = 37
Therefore, x = 37 and y = 11
