6 0
Since we don’t know the height of base or angles. We do know it is isosceles triangle.
x+4=3x-8
x-3x= -8-4
-2x= -12 multiply both sides by -1
2x=12
x=12/2
x=6
x+4=6+4=10
3x-8=3•6-8=18-8=10
Base equals x. x=10
AC=10

You have seven cards, numbered 3 through 9, and you pick one at random. If you pick a card with a prime number, you get 1 point;
Roman55 [17]

Answer:

He has \frac{-1}{7} number of points

Step-by-step explanation:

We have given that numbers from 3 to 9

So numbers will be 3,4,5,6,7,8,9

Here prime numbers are 3,5,7

And composite numbers are 4,6,8,9

So probability of getting prime number = \frac{3}{7}

And probability of getting composite number =\frac{4}{7}

It is given that if he gets prime number then he get 1 point and if he get composite number then he loss 1 point '

So value of number of point he has = 1\times \frac{3}{7}-1\times \frac{4}{7}=\frac{-1}{7}
