Total number of balls = 100

Number of balls with odd numbers = 50
Number of balls with number greater than 80 = 20
Number of balls greater than 80 and is odd = 10
⇒ Number of favourable outcomes = 50 + 20 - 10 = 60

P(odd or greater than 80) = 60/100 = 3/5

Answer: 3/5

Look at this triangle work out length AB
Paha777 [63]

Answer:

2√137

Step-by-step explanation:

To find AB, we can use the Pythagorean Theorem (a² + b² = c²). In this case, a = 22, b = 8 and we're solving for c, therefore:

22² + 8² = c²

484 + 64 = c²

548 = c²

c = ± √548 = ± 2√137

c = -2√137 is an extraneous solution because the length of a side of a triangle cannot be negative, therefore, the answer is 2√137.

PLZZZ HELP will mark brainliest!
erica [24]

Answer:

(3,8): No,  (-1,-11): Yes,  (2,7): Yes,  (0,-6): No

Step-by-step explanation:

Basically, you just substitute x and y with the numbers given.

18x - 3y = 15

y = 6x - 5

(3,8):

18(3) - 3(8) = 15

54 - 24 = 30  It is not equal to 15, so it does not work.

y = 6x - 5

8 = 6(3) - 5

8 = 13  It is not equal to 8, so it does not work.

Therefore, (3,8) is not a solution.

Try this for every pair and you will find that (-1,-11) and (2,7) are solutions.

I hope this helps!
