Answer:
C. the probability of it not happening is 0.3.
Step-by-step explanation:
Probability of event happening is of 0.7.
Either it happens, or it does not. The sum of these probabilities is 100%.
0.7 probability of happening, so 1 - 0.7 = 0.3 probability of not happening, and the correct answer is given by option C.
A is wrong as the probability is not 1, and B is wrong as the probability is higher than 0.5.

Answer:
sin∅= - √6/3
Step-by-step explanation:
Trigonometric function cos is even function which mean:
cos (-∅) = cos ∅
Trigonometric function sin is odd function which mean:
sin (-∅) = - sin∅ => sin∅ < 0
The basic trigonometric equation reads in this case with angle marked ∅:
sin²∅ + cos²∅ = 1 => sin²∅ = 1 - cos²∅ => sin²∅ = 1 - ( √3/3 )² =>
sin²∅ = 1 - (3/9) => sin²∅ = 1 - (1/3) = (3/3) - (1/3) = 2/3 => sin∅ = - √(2/3) =>
sin∅ = - √2/√3 => sin∅ = - √6/3

Answer:
j(-2) = i√2 + 6
Step-by-step explanation:
√-1 = imaginary number i
Step 1: Define
j(x) = √x + 6
k(x) = 9 - x
k(11) = x = 11
Step 2: Find k(11)
k(11) = 9 - 11
k(11) = -2
Step 3: Find j(-2)
j(-2) = √-2 + 6
j(-2) = √-1 · √2 + 6
j(-2) = i√2 + 6
