Answer:

C. 5 Red marbles

Step-by-step explanation:

If she started with 5 red marbles and had a probability of 1/5 of drawing a red marble, then there were 20 blue marbles, and 25 total marbles.

   5/25 = 1/5

If she added 5 red marbles, she now would have 10 red marbles and still 20 blue marbles, giving her 30 total marbles in the bag.

  10/30 = 1/3, so C is the right answer.  

You can rule out other choices by repeating the above steps and substituting appropriate values

Andrej [43]

Answer:

(Part A) The formula for finding the area of a circle is πr². (Part B) The radius of that circle would be 5.27 m. 10.54 m cut in half would be 5.27 m. (Part C) The area of this circle would be approx. 87.21 m². Using the formula from Part A, first square 5.27. That will equal 27.7729. Now, multiply that by 3.14 (I used that value for π) to get 87.206906 m². However, we have to round to the nearest hundredth, so 87.21 m² is the answer.

Which of the following describes the polynomial function?
Yanka [14]
B. It cant be A because a negative leading coefficient would mean it was turned facing down. It can't be C because the bottom of the loop is a turning point. It cant be C because it doesn't cross the x-axis.
