Sorting the data from smallest to largest is a useful first step that makes calculating Median and Mode easier

We know,  the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution.

The mode is the value that appears most often in a set of data values. If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value.

So, when we sorting the data from smallest to largest is a useful first step that makes calculating the median easier. Because median is the middle term of the ordered data set.

Similarly, It will be easier to find the most frequent in the ordered data set

that is mode

Hence, sorting the data from smallest to largest is a useful first step that makes calculating Median and Mode easier

Two students walk in the same direction along a straight path, at a constant speed - one at .90 m/s and the other at 1.90 m/s.a.
anyanavicka [17]

Answer:

a)The second student arrive 7 minutes and 36 seconds sooner

b)They have to walk 598,51 m

Step-by-step explanation:

Speed= Distance/Time

We are looking for time now

Time = Distance/Speed

First student

Time = 780 m/0.90 m/s=866,66 seconds

Second student

Time = 780 m/1.90 m/s=410,52 seconds

Difference=866,66-410,52= 456,14 seconds

In minutes

Difference= 456,14 seconds /60=7 minutes 36 seconds

Distance=Speed x Time

Speed¹ x Time¹ =Speed² x Time²

Time¹= Time² + 5.50 min

5.50 min =350 seconds

Time²  =Speed¹ x Time¹ /Speed²

Time²  =Speed¹ x (Time² + 350 seconds  ) /Speed²

Time²  =0.9 x (Time² + 350 seconds  ) /1.9

Time²  =0,4737 x (Time² + 350 seconds  )

Time²  =0,4737 Time² + 165,79 seconds

Time²  - 0,4737 Time² = 165,79 seconds

0,5263 Time² = 165,79 seconds

Time² = 165,79 seconds/0,5263 =315,01 seconds

Distance=1,9 x 315,01 seconds = 598,51 m

Given the following sequence, find the 14th term: 3, 1, –1, –3, –5, . . .
AVprozaik [17]
3, 1, -1, -3, -5
 -2  -2  -2  -2

a(n) = a₁ + d(n - 1)
a(n) = 3 - 2(n - 1)
a(n) = 3 - 2(n) + 2(1)
a(n) = 3 - 2n + 2
a(n) = -2n + 3 + 2
a(n) = -2n + 5
   a₁₄ = -2(14) + 5
   a₁₄ = -28 + 5
   a₁₄ = -23

The answer is C.

GalinKa [24]

Answer:

P(Male = 2) = 63.9%

Step-by-step explanation:

40000C2 / 50000C2

[(40000 * 39999) / (1*2)] / [(50000 * 49999 *) / (1*2)]

3,199,920,000 / 4,999,900,000

0.6399996799935999

P(Male = 2) = 63.9%
