Answer:
0.0009765625
Step-by-step explanation:
Each multiple choice question has 4 equally likely alternatives.
Hence, probability of guessing the right answer for 1 question is ![\[\frac{1}{4}\]](https://tex.z-dn.net/?f=%5C%5B%5Cfrac%7B1%7D%7B4%7D%5C%5D)
= 0.25
Hence, probability of guessing the wrong answer is = 0.75
The probability of guessing 5 or more questions correctly = probability of guessing 5 questions correctly & 1 question wrong + probability of guessing 6 questions correctly
= ![\[0.25^{5}*0.75+0.25^{6}\] ](https://tex.z-dn.net/?f=%5C%5B0.25%5E%7B5%7D%2A0.75%2B0.25%5E%7B6%7D%5C%5D%0A)
= 0.000732421875 + 0.000244140625
= 0.0009765625

Answer:
∠D = 68°
Step-by-step explanation:
In a quadrilateral that is inscribed in a circle, opposite angles are supplementary.
∠D = 180° - ∠B
∠D = 180° -112°
∠D = 68°

Since you don't know the value of b about the best that you could do is:
(2b)^4
16b^4
16b*b*b*b
Answer:
x² + 12x + 35
Step-by-step explanation:
The area of the blue section is x * x = x².
Pink: x * 7 = 7x
Green: x * 5 = 5x
Orange: 7 * 5 = 35
When we add these up we get x² + 12x + 35. Hope this helps!
