Complete question :
Suppose that of the 300 seniors who graduated from Schwarzchild High School last spring, some have jobs, some are attending college, and some are doing both. The following Venn diagram shows the number of graduates in each category. What is the probability that a randomly selected graduate has a job if he or she is attending college? Give your answer as a decimal precise to two decimal places.
What is the probability that a randomly selected graduate attends college if he or she has a job? Give your answer as a decimal precise to two decimal places.
Answer:
0.56 ; 0.60
Step-by-step explanation:
From The attached Venn diagram :
C = attend college ; J = has a job
P(C) = (35+45)/300 = 80/300 = 8/30
P(J) = (30+45)/300 = 75/300 = 0.25
P(C n J) = 45 /300 = 0.15
1.)
P(J | C) = P(C n J) / P(C)
P(J | C) = 0.15 / (8/30)
P(J | C) = 0.5625 = 0.56
2.)
P(C | J) = P(C n J) / P(J)
P(C | J) = 0.15 / (0.25)
P(C | J) = 0.6 = 0.60
Answer:
4/9
Step-by-step explanation:
No because a circle has an infinite number of lines of symmetry.
Answer:
12d = 156
Step-by-step explanation:
Carlos is reading 12 pages / day
The total amount to read is 156
In order to find the days, you have to divide 156 by 12 or
Equation:
12d = 156; furthermore
d = 13 days, meaning it will take 13 days to read 156 pages.
The geometric sequence is a sequence with a common ratio. The common ratio is the ratio between the succeeding term and the preceding term of a sequence and must be equal to a constant k.
Given a sequence 2, 4, 8, 16... This sequence is geometric in nature because of a constant common ratio of 2.'
Common ratio = 4/2 = 8/4 = 2
Hence a geometric sequence is characterized by its common ratio
