Answer:
78
Step-by-step explanation:
Since 13 is a prime, the least common multiple of it and 6 is their product. 6*13=78. Hope this helps!
Least Common Multiple of 6 and 13. Least common multiple (LCM) of 6 and 13 is 78.
6- 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78
13- 13, 26, 39, 52, 65, 78
(f+g)(x) = 7x -1 (Answer C)
Rewrite these two functions, one above the other, for ease in adding:
f(x) = 5x - 2
+g(x) =2x + 1
------------------
(f+g)(x) = 7x -1
70 + 7x
7(8+x+2)
Combine like terms in the parenthesis
7(8+2+x)
7(10+x)
Distribute
P = 16
Given
5W = 2P + 3R ← substitute W = 4 and R = - 4 into the equation
5(4) = 2P + 3(- 4), that is
20 = 2P - 12 ( add 12 to both sides )
32 = 2P ( divide both sides by 2 )
16 = P
Probabilty of not poor= 0.75
total of 11332 bonds.
7311 are good risk.
1182 are medium risk.
Poor risk
= total risk-(good risk+ medium risk)
= 11332-(7311+1182)
= 11332-8493
= 2839.
Poor risk = 2839
Probabilty that the ball choosen at random is not poor= 1 - probability that the ball is poor
Probability of poor = 2839/11332
Probabilty of poor= 0.2505
Probabilty that the ball choosen at random is not poor= 1- 0.2505
= 0.7495
To two decimal place= 0.75
