A. 1/18

B. 1/8

C. 1/3

D. 4/9

Answers

Answer 1

Answer: probability is (desired outcomes)/(total possible outcomes)

green:8
total possible=total
4+6+8=18 total

probablity=8/18=4/9

answer is D

Answer 2

Answer: There are 18 marbles in total and 8 green marbles. 8 out 18 of the possibilities will be green so it's 8/18 = 4/9.

Three vertices of a rectangle have coordinates (–3, 1), (7,1), and (7, –4). What are the coordinates of the fourth vertex of the rectangle?

A.
(–3, –4)

B.
(–3, –1)

C.
(7, –3)

D.
(7, 4)

Answers

The answer is A because a rectangle has sides that go straight down basically -3 there has to be two -3 for x coordinate and two 7 for y coordinate and the missing coordinate also has to line up with the coordinate right next to it so it must have -4 as it's coordinate so basically the coordinate vertically across from it has the same x coordinate and the coordinate horizontal from it has the same y coordinate. So it's (-3,-4)

If 2b= -3, what is the value of 1 – 4b?

Answers

If we have the expression 2b = -3, then the value of the expression 1 - 4b is 4.

Step 1: Solving for 'b'

We are given the equation 2b = -3. To isolate 'b,' we need to get rid of the coefficient 2 attached to 'b'. To do that, we'll divide both sides of the equation by 2:

2b / 2 = -3 / 2

b = -3/2

Step 2: Substitute 'b' in the expression 1 - 4b

Now that we have the value of 'b' as -3/2, we can substitute it into the expression 1 - 4b:

1 - 4(-3/2)

Step 3: Simplify the expression

To simplify the expression, we'll perform the multiplication first:

1 + 6/2

Next, we add 1 and 6/2:

1 + 3 = 4

Answer:

Step-by-step explanation:

2b= -3, what is the value of 1 – 4b?

2b= -3

b = -3/2

Then 1 - 4b

= 1- 4(-3/2)

= 1+12/2

= 1+ 6

= 7
