Solution:

<u>Step-1: Find the data.</u>

  • 70's: 1
  • 80's: 1
  • 90's: 2
  • 100's: 3
  • 110's: 4
  • 120's: 4
  • 130's: 2
  • 140's: 1

Data obtained (Smallest to biggest):

  • 70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140

<u>Step-2: Count the number of digits.</u>

  • 18 digits in data

<u>Step-3: Use the formula "Total digits/2".</u>

  • 18/2 = 9th digit

The 9th digit in the data is the median.

<u>Step-4: Revise the data.</u>

  • 70, 80, 90, 90, 100, 100, 100, 110, 110, 110, 110, 120, 120, 120, 120, 130, 130, 140

The median value of the line plot is 110.

Answer:

1: True, 2: False

Step-by-step explanation:

With the first one, probability by defintion is the odds of if an event will happen or not, so it is true.

With the second one, it is false as if something is for sure going to happen, it will have a 100% or "1" chance of occurring. If it has a 1% chance of occuring, it would be 0.01.

Quick question:)))
Mrrafil [7]

First and foremost is the vertex, which is either the highest point or the lowest point of the parabola (which’s is what the graph of a polynomial looks like). From the vertex, you can always determine the next two points closest to the maximum/minimum.

Another key feature includes the y-intercepts, which are important if you want to find the zeros of the polynomial. Sometimes, the x-intercepts may come in handy as well, but not as often as the y-intercepts.
