Answer:
<h2>y = 4</h2>
Step-by-step explanation:
Put x = 9 to the equation 3x + 4y = 43
(3)(9) + 4y = 43
27 + 4y = 43 <em>subtract 27 from both sides</em>
4y = 16 <em>divide both sides by 4</em>
y = 4
Answer: 131 degrees
Step-by-step explanation:
20y-11+4y+6+7y-7=360
31y-12=360
+12. +12
31y= 372
Divide by 31
Y= 12
BC= 4y+6+7y-7
4(12)+6+7(12)-7
BC= 131
First think out the equation, once you've done that multiply 3 by 25 to get 75
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:

or probability of its failing is:

<h3>Example:</h3>
Rolling a number smaller than 3 in a dice.
A= 2 (1,2)
B = 4 (3,4,5,6)

<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
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
