Answer:

.8

Step-by-step explanation:

5 red marbles, 2 Green marbles and 3 black marbles = 10 marbles

P (red or black) = number of red or black/ total

                          = (5+3)/10

                          =8/10

   decimal form  = .8

Red- 50% chance (.5)

Black- 30% Chance (.3)

Explanation:

The total amount of marbles is ten, meaning that we can change it to 100% no problem.

Green - 2 = 20% = .2

Black - 3 = 30% = .3

Red - 5 = 50% = .5

Answer:

y = 5x+7

Step-by-step explanation:

Parallel lines have the same slope so y = 5x+9 is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

The slope is 5

The new line will have a slope of 5

y = 5x+b

We know a point on the line (-2,-3)

Substitute this point into the equation

-3 = 5(-2)+b

-3 = -10+b

-3+10 = b

7 = b

y = 5x+7

Suppose you are given that p = 2q+1 and that p = 8.
iVinArrow [24]

Answer:

We conclude that the following statements can be proved such as:

  • 2q+1 = 8    

Step-by-step explanation:

Given the expression

p = 2q+1

Given

p = 8

IF WE SUBSTITUTE p=2q+1 in p=8

Now, substituting p = 2q+1 in the expression p=8

p = 8

2q+1 = 8         ∵ p = 2q+1

Therefore, we conclude that the following statements can be proved such as:

  • 2q+1 = 8
