Ok so the hint is very useful and it says to divide the figure into 2 rectangles so if we do so the shorter rectangle's side lengths would be 9, 5, 9, and 5 because that last little bit of length is equal to the longer rectangle and it is also exactly half of 10. so to find the area of a rectangle the formula is a=length* width. so if you were to plug it in it would be a= 9*5 and it equals 45 so you have the area of the first rectangle. Then to find the area of the second rectangle you would do the same thing as the first one. and you would end up with 75. Then just add those two numbers up to get the area

6)
2(9+10) = 38
2(5+6) = 22

P = 38+22=60 in

14)
9 x 10 = 90
6 x 5 = 30
A = 90+50 = 140 in^2

Describe the difference between a probability derived from the analytic view (logical analysis), the Relative Frequency view (sa

oee [108]

Answer:

See the explanation

Step-by-step explanation:

<h2>Analytic View:</h2>

If and event can occur in A number of way and fail in B number of ways, then probability of its occurrence is:

$P(A)= \frac{A}{A+B}$

or probability of its failing is:

$P(B)=\frac{B}{A+B}$

<h3>Example:</h3>

Rolling a number smaller than 3 in a dice.

A= 2 (1,2)

B = 4 (3,4,5,6)

$P(A)= \frac{2}{2+4}=\frac{1}{3}$

<h2>Relative Frequency View:</h2>

Definition of Probability in terms of past performances (data). It can be taken as how often things happens divided by all outcomes.

<h3>Example:</h3>

A batter has 50 safe hits at 200 bats, which makes his batting average $\frac{50}{200}= 0.25$ which is the probability.

<h2>Subjective View:</h2>

When you define a probability due to personel beleif in the likelihood of an outcome. It involve no formal calculations and varies from person to person, depending on their past experience.

<h3>Example:</h3>

A person beleives that probability that the batter will hit safely in the next bat is 0.75
