A researcher records the hospital admission rates for coronary heart disease at 10 local hospitals. She finds that 2 different h
In-s [12.5K]

The central tendency researcher use to describe these data is "mode".

<h3>What is mode?</h3>

The value that appears most frequently in a data set is called the mode. One mode, several modes, or none at all may be present in a set of data. The mean, or average of a set, and the median, or middle value in a set, are two more common measurements of central tendency.

Calculation of mode is done by-

  • The number that appears the most frequently in a piece of data is its mode.
  • Put the numbers in ascending order by least to greatest, then count the occurrences of each number to quickly determine the mode.
  • The most frequent number is the mode.
  • Simply counting how many times each number appears in the data set can help you identify the mode, which is the number that appears the most frequently in the data set.
  • The figure with the largest total is the mode.
  • Example: Since it happens most frequently, the mode for the data set [5, 7, 8, 2, 1, 5, 6, 7, 5] is 5.

Calculate the area of the shaded sector in the circle​
agasfer [191]

Answer:

Approximately, 6.283..

Step-by-step explanation:

First calculate the area of the whole circle

We have radius(r)=4 cm

Area of circle(a)=pir^2

=pi×(4)^2

=pi×16

=Approximately,50.265......

A cirlce has a total of 360 degrees

Therefore,we can conclude 360 degrees=50.265...

or,1 degree=50.265/360

1 degree=Approximately,0.139

Now,

Area for the shaded region = Area of 45 degree

=0.139×45=Approximately,6.283.....

Therefore,the area of the shaded region is approximately,6.283....
