Answer:
hello your question has some missing information attached below is the missing information
answer : 112 black balls
Step-by-step explanation:
Given data:
Each bag contains ; 10 balls
Total number of ball = 100 balls
<u>first: calculate the number of Black balls to be picked from the three bags</u>
From bag 1 = 0.4 * 0.35 * 10 = 1.4 balls
From bag 2 = 0.8 * 0.45 * 10 = 3.6 balls
From bag 3 = 0.3 * 0.2 * 10 = 0.6 ball
Total black balls picked = 5.6
∴ percentage of black balls picked given that each bag contains 10
5.6 / 10 * Total balls available = 56 balls = 56% of 100 balls
Hence If the player plays this game 200 times the number of black balls he will pick = 56% * 200 = 112 balls

Answer:
Resulting plot in the image attached
Step-by-step explanation:
Start by making a table of (x,y) pairs that satisfy this equation. Notice that two pairs would be enough, but it is always safer to obtain at least three to see them actually "aligned".
We are trying to find values for y when x= 0, 2, and 4 to make our calculations simple:
When x = 0 then: So we plot the value (0,-3) on the x-y plane.
When x = 2 then: So we plot the value (2,-2) on the x-y plane.
When x = 0 then: So we plot the value (4,-1) on the x-y plane.
Please see the points and the resulting line in the image attached
