There is a 25% chance that Dane will make a three-point shot during a basketball game. A random-number generator generated 10 se
Gelneren [198K]

Answer:

the 25% chance is wrong, it is actually 20%

Step-by-step explanation:

Based on the table of trials shown in the picture, it seems that the 25% chance is wrong. In the table, there are 10 trials and each one has 5 numbers generated, meaning there are a total of 50 numbers generated. Out of these 50 numbers, only 10 are the number 3. Since 3 is the only number that represents a three-point shot, that would make it a 20% (10 / 50) chance that Dane makes a three-point shot in a basketball game.

(15)Simplify the expression below. Show your work -(-7y+12)
kotykmax [81]
15. -(-7y + 12) = 7y - 12

16. 1/a = 16/18
      cross multiply
      16a = 18
      a = 18/16 = 9/8

17. 8x - 12 = 4x + 24
      8x - 4x = 24 + 12
      4x = 36
      x = 36/4
      x = 9

18. -6b > 42           4b > -4
       b < 42/-6          b > -4/4
       b < - 7              b > -1
so b < -7 and b > -1

19. 6 more then the product of 8 and n
      6 + 8n

20. 45 = 3b + 69
      45 - 69 = 3b
      -24 = 3b
      -24/3 = b
      -8 = b
