Start by doing the binomial expansion of (x+y)^6 where x represents success. This is
(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)
We are interested in the x^3y^3 term which represents exactly 3 sucesses. Since the probalbility of sucess and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is
20/64 = .3125 which is 31.25%

1. see attached
2. the figure is reflected in the y-axis
Step-by-step explanation:
1.
The given transformation moves each point horizontally to the same
distance on the other side of the y-axis. This is shown in the attachment.
2.
The given rule ...
(x, y) → (-x, y)
is the most precise description of the transformation. In English, it can be
described as a reflection in the y-axis
Step-by-step explanation:
Correct me if I'm wrong
Step-by-step explanation:
In isoceles triangle two sides are equal and two angles are equal.
Then,
∠R = ∠T = (5x-40)°
Then,
∠RTS + ∠STU = 180° (bcoz it lies on a straight line)
(5x-40) ° + 5x = 180°
10x = 220°
x = 22°
Therefore,
Option A is correct✔
