The answer is 10 because all the angles are equal making it a equilateral triangle.

Therefore, the sides are all equal to one another, 3x - 8 = 5x - 20.

You just solve for x and get 6. You then plug in 6 for x and evauluate the equation, getting 10.

Answer:

10

Step-by-step explanation:

This is an equilateral triangle ( because  all 3 angles have  the same measure)

So 3 all sides  are equal, therefore:-

5x - 20 = 3x - 8

2x = 12

x = 6

So DE =  3(6) - 8

= 10 units

A basketball player that shoots 80% from the free throw line attempts two free throws. The notation for conditional probability
Juliette [100K]

Answer:

P(made 2nd attempt|made 1st attempt)=P(made 2nd attempt)

Step-by-step explanation:

Here given that a basketball player that shoots 80% from the free throw line attempts two free throws.

If x is the no of shoots he makes (say) then we find that each throw is independent of the other.

In other words, because he made successful first attempt, his chances for second attempt will not change

Prob for success in each attempt remains the same as 0.80

Hence I throw is independent of II throw.

When A and B are independent,then we have

P(A/B) = P(A)

Hence answer is

P(made 2nd attempt|made 1st attempt)=P(made 2nd attempt)
