Answer:

Step-by-step explanation:

1)

Probability for flipping one coin is 1/2

Probability for flipping two coins should be about 1/2 * 1/2 which is 1/4

There is a 1/4 chance

2)

First you must find the sum of all the marbles which would be 20

Now, put the blue marbles over the sum of 20 which is

5/20 or simplified to 1/4 which is the probability of choosing a blue marble

3)

If the probability of landing on yellow is 4/9, whatever is left is the probability of not landing on yellow which is 5/9

Someone please help me state all the possible names for the figure
Otrada [13]

Answer:

B.

Step-by-step explanation:

To answer, lets look at the definitions of each name.

First, a quadrilateral. A quadrilateral is a polygon in Euclidean plane geometry with four edges and four vertices, so it basically just has 4 sides, which this figure has, so this figure is a quadrilateral.

Next, a parallelogram. A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel. So as long as a figure has 4 sides and at least 2 opposite sides that will never collide, it is a parallelogram. Because our figure has 4 sides and each pair of opposite sides is parallel, this figure is a parallelogram.

Last, a rectangle. A rectangle is a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square. So, as long as there are 4 sides and 4 right angles, and 2 of the opposite sides are longer than the other set of opposite sides, it is a rectangle, and this figure fills all the requirements.

So, since the figure is a quadrilateral, a parallelogram, and a rectangle, the answer is B.

Hope this helps :)

For #1 you have to make the denominator the same so it will be 4 and 8/16 and 5 and 9/16 Then subtract them. For #3 you divide 175 by 7.
 For #4 you do the number of days and multiply it by the number of people
 For #5 you multiply the two numbers. For #6 you
