Answer:
a) No
b) 42%
c) 8%
d) X 0 1 2
P(X) 42% 50% 8%
e) 0.62
Step-by-step explanation:
a) No, the two games are not independent because the the probability you win the second game is dependent on the probability that you win or lose the second game.
b) P(lose first game) = 1 - P(win first game) = 1 - 0.4 = 0.6
P(lose second game) = 1 - P(win second game) = 1 - 0.3 = 0.7
P(lose both games) = P(lose first game) × P(lose second game) = 0.6 × 0.7 = 0.42 = 42%
c) P(win first game) = 0.4
P(win second game) = 0.2
P(win both games) = P(win first game) × P(win second game) = 0.4 × 0.2 = 0.08 = 8%
d) X 0 1 2
P(X) 42% 50% 8%
P(X = 0) = P(lose both games) = P(lose first game) × P(lose second game) = 0.6 × 0.7 = 0.42 = 42%
P(X = 1) = [ P(lose first game) × P(win second game)] + [ P(win first game) × P(lose second game)] = ( 0.6 × 0.3) + (0.4 × 0.8) = 0.18 + 0.32 = 0.5 = 50%
e) The expected value 
f) Variance 
Standard deviation 
Answer:vertical angle
Step-by-step explanation:
Ten to the <span>negative second power L over one cL is the one among the following choices that is a possible equivalence that can be used in a conversion. The correct option among all the options that are given in the question is the third option or option "C". I hope the answer helps you.</span>
Let's rewrite the expression correctly:
(12x3 - 11x2 + 22x - 5) / (4x -1)
Dividing the expression between (4x -1) we have:
3x2 - 2x + 5
We can check the result:
(3x2 - 2x + 5) * (4x-1)
= 12x3 - 8x2 + 20x - 3x2 + 2x - 5
= 12x3 - 11x2 + 22x - 5
Division OK.
Answer:
The result of the division is:
3x2 - 2x + 5
6x + 3y = 79.5
3x + 2y = 41 y = -3/2x + 41/2 y = -1.5x + 20.5
6x + 3(-1.5x + 20.5) = 79.5
6x - 4.5x + 61.5 = 79.5
1.5x + 61.5 = 79.5
1.5x = 18
x = 12
Each shirt costs $12.
Now insert that number into the x to find the cost of each tie.
3(12) + 2y = 41
36 + 2y = 41
2y = 5
y = 2.5
Each tie costs $2.50.
