The correct answer for the question that is being presented above is this one: "0.5" <span>The probability that a normal random variable is less than its mean is 0.5. In a normal distribution, 1.0 refers to the one that is stable and is in equilibrium.</span>
(x+12)^2=(x+12)(x+12) = x^2 +12x + 12x + 144
= x^2+24x+144
<h2>
Answer:</h2>
<u>By supplementary angle property</u>,
x + 78° = 180°
x = 180° - 78°
x = 102°.
I have a feeling it B but I don’t know maybe C
