Answer:

So, you have to prove that Triangle ABC is congruent to Triangle ADC

it has been proved that they are congruent.

Step-by-step explanation:

We already know that Angle B is congruent to Angle D and AC bisects Angle BAD.

Because given rules one angle of one triangle is equal to the same side of the other.

Because of bisection, you also now know that Angle BAC is congruent to Angle CAD.

The sum of a triangle is 180 degrees.

Angle B and Angle BAC are equal to Angle D and Angle CAD.

180 degrees subtract from both of these if you knew the degrees would give the same answer.

This proves they are congruent.

One in 100 tennis balls produced at a factory is defective. if you randomly select five tennis balls, what is the probability th

Alex73 [517]

You can tell this is a binomial distribution since there is specific failure or success (getting a defective is success, for example).

X~B(5, 0.01)

P(X≥1)= 1-P(X≤1)
=1-(0.999)
=9.80×10⁴ probability of getting at least one that is defective.

Hope I helped :)

What is 24% of 80?

juin [17]

In math, IS represents = OF represents multiply

1. So for the first problem is saying 24% * 80 24% is the same as .24 so .24*80=19.2

2. For this one the problem is saying 15=30%*x So for this we need to find x. So we divide both sides by .3 and get x = 50

3. You do the same thing as in 2. Im not gonna do all ur homework so you can do this one.

Hope that helps :)<span />
