Answer:
(if its a true or false question) True
Step-by-step explanation:
<u>We know-</u>
<u>Area of a circle = </u>
A=(π)r2
<u>Circumference of a circle = </u>
C=2(π)r
<u>Where pi is a constant and r is the radius of the circle.</u>
<u>Using these two formulas we can express A in terms of C as follows:</u>
<u />
c2=[2(π)r]2
⇒ c2=4[(π)2]r2 ⇒ c2=4(π)[(π)r2]
As (π)r2=A ⇒c2=4(π)A
<u>Therefore:</u>
A=c2/4(π)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Proportion of males, P(M) = 77% = 0.77
Proportion of females = ( 1 - proportion of males) = (1 - 0.77) = 0.23
Percentage of males who smoke cigar = 11.3% = 0.113
Percentage of female who smoke cigar = 2.1% = 0.021
Expressing cigar smoking Data as conditional probability :
P(male and smoking) = P(M n C) = 0.113
P(Female and smoking) = P(F n C) = 0.021
Probability of smoking cigar Given the person is a male :
P(C | M) = P(M n C) / P(M)
Probability of smoking cigar Given person is a female :
P(C | F) = P(F n C) / P(F)
Find the probability that the selected subject does not smoke cigars given that the subject is male?
No smoking Given Male = 1 - P(C | M)
P(C | M) = P(M n C) / P(M)
P(C | M) = 0.113 / 0.77
P(C | M) = 0.1467
1 - P(C | M)
1 - 0.1467
= 0.8533
