Answer:

<h2><u><em>P = 16</em></u></h2><h2><u><em>C = 24-P = 8</em></u></h2>

Step-by-step explanation:

Heads: P + C = 24

C = 24 - P

Legs: 4P + 2C = 80

Substitute, from heads: 4P + 2 (24 - P) = 80

4P + 48 - 2P = 80

2P = 32

<u><em>P = 16</em></u>

<u><em></em></u>

<u><em>C = 24-P = 8</em></u>

====================

Check:

P + C = 16 + 8 = 24

4P + 2C = 4(16) + 2(8) = 64 + 16 = 80

Answer:

p percent of the observations are less than the value and (100 - p) percent are more than this value.

Step-by-step explanation:

Given : The pth percentile is a value such that approximately

Solution :

Definition : A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls

So, The pth percentile means p percentage of observations in a group of observations falls bellow the value

So, (100-p) percentage of observations in a group of observations falls above the value

So, Option a is true

Hence p percent of the observations are less than the value and (100 - p) percent are more than this value.

Mariana [72]

Answer:

Since the difference between the value for each year is constant, this is an arithmetic sequence.

Step-by-step explanation:

Year 2 - Year 1 = 21,750 - 20,000 = 1,750

Year 3 - Year 2 = 23,500 - 21,750 = 1,750

Year 4 - Year 3 = Year 5 - Year 4 = 1,750
