Answer:
TRUE
Step-by-step explanation:
If you fold so the vertex of the angle is through the fold, and the two rays of the angle are pressed into coincidence by the process of folding, the fold will be an angle bisector.

Answer:
complete the missing value in the solution
Step-by-step explanation:
Simplifying
6x + 7y = 4x + 4y
Solving
6x + 7y = 4x + 4y
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
6x + -4x + 7y = 4x + -4x + 4y
Combine like terms: 6x + -4x = 2x
2x + 7y = 4x + -4x + 4y
Combine like terms: 4x + -4x = 0
2x + 7y = 0 + 4y
2x + 7y = 4y
Add '-7y' to each side of the equation.
2x + 7y + -7y = 4y + -7y
Combine like terms: 7y + -7y = 0
2x + 0 = 4y + -7y
2x = 4y + -7y
Combine like terms: 4y + -7y = -3y
2x = -3y
Divide each side by '2'.
x = -1.5y
Simplifying
x = -1.5y
Answer:
a) 0.2182
b) 0.0691
c) 0.9309
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly b successes on n repeated trials, and B can only have two outcomes.
In which is the number of different combinations of b objects from a set of n elements, given by the following formula.
And p is the probability of B happening.
In this problem we have that:
Bin(20,0.2).
This means that
(a) P(B=4).
(b) P(B≤1).
(c) P(B>1).
Either B is less than or equal to 1, or B is larger than 1. The sum of the probabilities of these events is decimal 1. So
We have that, from b),
So
