1st Image:-

Answer:

a) No
b) No
c) Yes
d) No

Step-by-Step Explanation:

We can use the Pythagoras Theorem to check whether it is a right triangle.

Hypotenuse^2 = 1st Side^2 + 2nd Side^2

a) 7, 12, 14

Therefore,
=> 14^2 = 7^2 + 12^2
=> 196 = 193
RHS is not equal to LHS.

Therefore, its not a Right Triangle.

b) 6, 14, 19

Therefore,
=> 19^2 = 6^2 + 14^2
=> 361 = 232
RHS is not equal to LHS.

Therefore, its not a Right Triangle.

c) 12, 35, 37

Therefore,
=> 37^2 = 12^2 + 35^2
=> 1369 = 1369
RHS is equal to LHS.

Therefore, it is a Right Triangle.

d) 4, 8, 9

Therefore,
=> 9^2 = 4^2 + 8^2
=> 81 = 80
RHS is not equal to LHS.

Therefore, its not a Right Triangle.

Answer: 352 ft^3

Step-by-Step Explanation:

r = 4 ft
h = 7 ft

Volume = πr^2h

Therefore,
= πr^2h
= π * r^2 * h
= 3.14 * 4^2 * 7
= 3.14 * 16 * 7
= 351.68

Volume = 351.68 ft^3
Rounded off = 352 ft^3

What is the probability that a randomly selected graduate has a job if he or she is attending college? Give your answer as
Andrej [43]

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
