Answer:

a. 0.308 = 30.8% probability that a red ball is drawn.

b. 0.816 = 81.6% probability that the ball drawn is not white.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

308 + 184 + 508 = 1000 balls

a.A red ball is drawn

308 balls are red. So

308/1000 = 0.308

0.308 = 30.8% probability that a red ball is drawn.

b.the ball drawn is not white.​

1000 - 184 = 816 are not white.

816/1000 = 0.816

0.816 = 81.6% probability that the ball drawn is not white.

Knowing that
Molodets [167]

Answer:

a. x/y = 2          b) y/x +y =1/3    c) x-y/y= 1     d) y/x = 1/2

Step-by-step explanation:

Solve for  

a) x/y

as we know x +y/y  = 3

 x+y= 3y  

x= 3y-y

x= y(3-1)

x/y= 3-1

x/y = 2

b)  y/x+y

as we know x +y/y  = 3

x+y = 3y

1= 3y/x+y

1/3 = y/x+y

So y/x +y =1/3

C) x-y /y

as we know x +y/y  = 3

x +y = 3y

subtracting 2y from both sides  

x +y -2y = 3y- 2y

x-y = y

dividing both sides by y

x-y/y = y/y

x-y/y= 1

d) y/x

as we know x +y/y  = 3

x +y = 3y

x= 3y- y

x= 2y

dividing both sides by x

x/x = 2y/2x

1 = 2 x (y/x)

1 / 2 = y/x

Or y/x = 1/2

Best of luck.

please mark me brainliest.

Solve: -7 < 2x+5 < 7
kondor19780726 [428]

Answer:

- 6 < x < 1

Step-by-step explanation:

first things first:

- 7 < 2x  + 5 \\  - 7 - 5 < 2x  + 5 - 5 \\  - 12 < 2x \\  - 6 < x

now:

2x + 5 < 7 \\ 2x + 5 - 5 < 7 - 5 \\ 2x < 2 \\ x < 1

now the intersection is:

- 6 < x < 1
