Answer:
Step-by-step explanation:
let A=favorable outcomes for getting multiple of 2
they are 21,22,23,24,25,26,
41,42,43,44,45,46,
61,62,63,64,65,66
P(A)=18/36
let B=total of 8
favorable outcomes are 26,35,44,53,62
P(B)=5/36
P(A∩B)=3/36
P(A OR B)=P(A∪B)=P(A)+P(B)-P(A∩B)=18/36+5/36-3/36=20/36=5/9
9.8
sqrt(12)=3.5 × sqrt(8)=2.8 = 9.8
A. x = -3
B. x = 2
C. x = 9/10
(A) –12x + 9 = –15x
Collect like terms
9 = -15x + 12x
9 = -3x
x = 9 / -3
x = -3
(B) 4.5x + 11.5 = 8.5x + 3.5
4.5x - 8.5x = 3.5 - 11.5
-4x = -8
x = -8 / -4
x = 2
(C) 23x – 9 = 13x
-9 = 13x - 23x
-9 = -10x
x = -9 / -10
x = 9/10
41
1. Multiply 5 by 6 in order to get to the 9th number. (5 places away, 4 were given.) Also, notice that the difference between all of the numbers are consistently 6.
2. Add 30 to 11, which gives you 41.
