Based on time conversion, the age of a teacher who is 50 years old in seconds is 1577880000 seconds.
<h3>What is the age of a teacher who is 50 years in seconds?</h3>
The age of the teacher in years is converted to seconds as follows:
- 60 seconds = 1 minute
- 60 minutes = 1 hour
- 24 hours = 1 day
- 3651/4 days = 1 year
Thus:
50 years to seconds will be:
50 × 365.25 × 24 × 60 × 60 = 1577880000 seconds.
Therefore, the age of a teacher who is 50 years old in seconds is 1577880000 seconds.

Answer:
I cant tell is the 'x' is supposed to be a variable or a multiplication sign. IF its a multiplication sign then the answer is -30. Btu if its a variable then its in its simplest form there isn't any way to solve that equation.
Answer:
269
Step-by-step explanation:
The margin of Error is E = 0.05
The level of significance is, α = 1 - confidence level = 1 - 0.9 = 0.1
Assume that the proportion is, p =0.5
From the standard normal table, observe that the critical value of Z for two tail test and 10% level of significance is 1.64
The calculation of sample size is as follows: n = (Z/E)²p(1-p)
n = (1.64/0.05)²0.5 (1 - 0.5)
n = (1.64/0.05)² 0.25
n = 1075.84 × 0.25
n = 268.96 ≈ 269
The required sample size with the given margin of error approximately is 269. This value indicates the size of the customers who are using this company’s products.
<span>Hi! All you need to know is that cot stands for cotangent and its the reciprocal of tan i.e. cot(x) = 1/tan(x). You probably know that tan(pi/4) = 1 and that tan(3pi/4) = -1. Happily in these cases it means that cot and tan come out the same (1/1 = 1 and 1/-1 = -1).
-1 - (+1) = -2 and this divided by pi/2 = -2/(pi/2) which looks a bit untidy so multiply the top and bottom by 2 (to get rid of the 2 in pi/2) and the answer is -4/pi. HTH</span>
