The probability of drawing a white ball is 1/4

Explanation:
When we solve for probability, we want to find out how many of something there is out of its total. So in this case, we want to see how many white balls there are out of the totals balls in the box. We already know that there are 10 white balls, so we need to figure out the total balls in the box, by adding up. 8 green balls + 16 red balls + 10 white balls + 6 pink balls = 40 balls in total. Now we know that the fraction would be 10/40, as there are 10 white balls out of 40 total balls. Finally, we simplify the fraction to 1/4, therefore the answer is B.

You find probability of drawing the marble by doing specific marble/total marbles. To find total marbles, add all the marbles:
8 + 16 + 10 + 6 = 40
Since we are searching for the probability of drawing the white marble and there are 10 white marbles,:
10/40 simplifies to 1/4 so b!

The sum of two consecutive even integers is 18. Write an equation to find the integers.
sdas [7]

Answer: 8 and 10  Step-by-step explanation: Consecutive means right beside. For example, the consecutive of 4 is 5 and 3. Since it's asking for EVEN integers, you need to add 2 to the x... for example, the nearest consecutive even number to 4 is 6 (you add 2). Then, solve like normal!

The base of a parallelogram is 1.4 feet long and the height is 0.32feet. What is the area of the parallelogram ​
bija089 [108]

Step-by-step explanation:

In a parallelogram

base (b) = 1.4 feet

height (h) = 0.32 feet

Now

Area of the parallelogram

= b * h

= 1.4 * 0.32

= 0.448 feet²

Hope it will help :)

Graph the image of the figure after a dilation with a scale factor of 3 centered at (2,−7) . Use the Polygon tool to graph the q
Luba_88 [7]

Answer:

  see attached

Step-by-step explanation:

Each point moves 3 times the distance from the center of dilation that it was.

You can compute the new coordinates by ...

  L = P - O . . . . . the length from O to P is P-O for some point P and origin O

Then 3 times that distance is

  3L = 3P -3O

We want to find the point P' that is 3L from O, so we add this distance to the coordinates of O. We get ...

  P' = 3L +O = 3P -3O +O

  P' = 3P -2O

So, for the lower left point A(-2, -7), the dilated image point A' is ...

  A' = 3(-2, -7) -2(2, -7) = (-6, -21) +(-4, 14) = (-10, -7)

That is, ...

  A' = 3A +(-4, 14)

The coordinates of the remaining points can be found similarly.

___

On a graph, it is usually fairly easy to count the grid squares in each direction between the point of interest and the center of dilation. The image point is 3 times the distance in each direction (horizontally, vertically).
