Answer:
The error interval for x is:
![[15.375,15.384]](https://tex.z-dn.net/?f=%5B15.375%2C15.384%5D)
Step-by-step explanation:
In order to determine the error interval for x, We have to get the all the number which could be rounded off to
.
These number can be listed in order such as:
15.375 15.376 15.377 15.378 15.379 15.380 15.381 15.382 15.383 15.384
Therefore, the error interval for x is:
![[15.375,15.384]](https://tex.z-dn.net/?f=%5B15.375%2C15.384%5D)
we know that
The intersection point of both graphs is a common point for both functions, for which for the same input value, both functions will have the same output value.
so
the point of intersection is 
for an input value equal to 
the output value for both functions is 
therefore
<u>the answer is the option</u>
X= 4
Hello from MrBillDoesMath!
Answer:
-52. None of the provided choices is correct
Discussion:
Following the usual order of math operations none of the provided answers is correct. The answer is
2*3 + 4- 62 = => * before + and -
(2*3) + 4 - 62= => 2*3 = 6
6 + 4 -62 = => 6 + 4 = 10
10 - 62 =
-52
Thank you,

Answer:
29 years
Step-by-step explanation:
The population of the Chinese people is 1.3 bn, and they grow at a rate of 0.49% per year. To get the number of years it requires to reach 1.5 bn, we use this method
after x years, the population will be
1.3 * 1.0049^x
so you just need to solve
1.3 * 1.0049^x = 1.5
1.0049^x = 1.5/1.3
x log 1.0049 = log(1.5/1.3)
x = log(1.5/1.3)/log(1.0049)
x = 0.062 / 0.002122
x = 29.25 years
Therefore, at the rate of 0.49%, the Chinese population of 1.3bn needs 29 years to clock 1.5 bn
