Answer:
2050
Step-by-step explanation:
<u>Year 2010</u>
The number of people over 65 years of age =32 million
Total population = 307 million.
P(meeting a person over 65 at random in 2010)
![=\dfrac{32 \text{ million}}{307\text{ million}} \\\\=0.1042](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B32%20%5Ctext%7B%20million%7D%7D%7B307%5Ctext%7B%20million%7D%7D%20%5C%5C%5C%5C%3D0.1042)
<u>Year 2050</u>
The number of people over 65 years of age =88 million
Total population = 434 million.
P(meeting a person over 65 at random in 2050)
![=\dfrac{88\text{ million}}{434\text{ million}} \\\\=0.2028](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B88%5Ctext%7B%20million%7D%7D%7B434%5Ctext%7B%20million%7D%7D%20%5C%5C%5C%5C%3D0.2028)
Conclusion: Since 0.2028 is greater than 0.1042, the chances of meeting a person over 65 at random will be greater in 2050
Sum means add, a number means x, and four means, uh, 4...
x+4. is what you're looking for
Answer: x = pi
sin²x - 2cos x - 2 = 0
⇔ 1 - cos²x - 2cos x - 2 = 0
⇔ cos²x + 2cos x + 1 = 0
⇔ (cos x + 1)² = 0
⇒ cos x + 1 = 0
⇔ cos x = -1
⇒ x = pi + k2pi
because 0 ≤ x < 2pi
=> x = pi
