Suppose that we have a sample space S5 {E1, E2, E3, E4E4E, E5, E6, E7}, where E1, E2, . . ., E7 denote the sample points. The following probability assignments apply: P(E1) 5 .05, P(E2) 5 .20, P(E3) 5 .20, P(E4) 5 .25, P(E5) 5.15, P(E6) 5 .10, and P(E7) 5 .05. LetA5{E1,E4E4E,E6}B5{E2E2E,E4E4E,E7E7E}C5{E2E2E,E3,E5,E7E7E}a.Find P(A(A(), P(B), and P(C).b.Find AB and P(A(A(>B).d.Are events A and C mutually exclusive?C mutually exclusive?Ce.Find Bc and P(Bc).
Answers
Answer:
P(A) = 0.4 ; P(B) = 0.50 ; P(C) = 0.60 ; P(A u B) = 0.65 ; P(A n B) = 0.25 ;
A and C are mutually exclusive ;
0.5
Step-by-step explanation:
S = {E1, E2, E3, E4, E5, E6, E7}
P(E1) = .05, P(E2) = .20, P(E3) = .20, P(E4) = .25, P(E5) = .15, P(E6) = .10, and P(E7) = .05
Let:
A{E1,E4,E6}
B{E2,E4,E7}
C{E2,E3,E5,E7}
P(A) = 0.05 + 0.25 + 0.10 = 0.40
P(B) = 0.20 + 0.25 + 0.05 = 0.50
P(C) = 0.20 + 0.20 + 0.15 + 0.05 = 0.60
AUB = {E1, E2, E4, E6, E7}
P(A u B) = 0.05 + 0.20 + 0.25 + 0.10 + 0.05 = 0.65
AnB = {E4}
P(A n B) = 0.25
A and C are mutually exclusive if AnC = ∅
A n C = ∅
Hence, A and C are mutually exclusive.
B complement = B' = {E1, E3, E5, E6}
P(B') = 0.05 + 0.20 + 0.15 + 0.10 = 0.5

Answer:
L = 5[tex]\sqrt{10}[/tex]
Step-by-step explanation:
use Pythagorean Theorem:
L² + (5[tex]\sqrt{2}[/tex])² = (10[tex]\sqrt{3}[/tex])²
L² + 25(2) = 100(3)
L² + 50 = 300
L² = 250
L = [tex]\sqrt{250}[/tex] = [tex]\sqrt{25}[/tex] · [tex]\sqrt{10}[/tex] = 5[tex]\sqrt{10}[/tex]
Answer:
by Pythagoras law
(10√3)²=l²+(5√2)²
100×3-25×2=l²
l²=25o
l=√250=5√10
:.l=5√10

Answers
Answer:
-3 and -5
Step-by-step explanation:
The zeros are where the line touches the x-axis
From the graph we can see that the line touches those points.
You can also determine it from the equation because the equation is in factored form, which is (x-r1)(x-r2)
Remember that it is minus so although it is +3 and +5 the actual zero is negative!!

Solve the system of equations using elimination
Answers
Answer:
(1, 3).
Step-by-step explanation:
x + 2y = 7
3x - 2y = -3
Adding the 2 equations will eliminate y:
4x = 4

x = 1
Plug x = 1 into the first equation:
1 + 2y = 7
2y = 6
y = 3.
