Answer:

Step-by-step explanation

Let the number be y

y doubled = y×2=2y

2y increases by 3 = 2y+3=

2y +3 is more than 6 but less than 20

2y+3 > 6

2y+3< 20

Solve for y

2y>6-3

y>3/2

2y+3<20

2y<20-3

2y<17

y<17/2

2. Find the median of the data set: 15, 6, 7, 10, 8, 9, 8, 14, 13.<br><br>please help asap​
dangina [55]
<h2>9</h2>

To find the median the first thing we need to do is organize the numbers from smallest to largest:

6 7 8 8 9 10 13 14 15

Then if the amount of numbers is odd, the median is the number which is in the middle. In this case the middle number is 9.

6 7 8 8 9 10 13 14 15

Hope this helps mate! Best of luck to you. :)

Mar 12: 3
erastovalidia [21]

Answer:

  • Mar 18: 125
  • Mar 19: 318
  • Mar 20: 743
  • Mar 25: 15,070

Step-by-step explanation:

The six seemingly arbitrary points have no common difference or ratio, so cannot be modeled by a linear or exponential function.

The differences of the differences are not constant at any level, so the only polynomial model is 5th-degree. It is ...

  (6n^5 -95n^4 +600n^3 -1825n^2 +2814n -1320)/60

where n = days after Mar 11. (Mar 12 corresponds to n=1.) The domain is n ≥ 1.

____

The 5th-degree polynomial increases very fast, but not as fast as an exponential function would.

The values for Mar 12 through Mar 25 are ...

  3, 8, 11, 16, 25, 50, 125, 318, 743, 1572, 3047, 5492, 9325, 15070
