We have been given an expression
. We are asked to find the solution to our given expression expressed as scientific notation.
Let us simplify our given expression.
Using exponent property
, we will get:
![8.5\times 2\times 10^3\times 10^5](https://tex.z-dn.net/?f=8.5%5Ctimes%202%5Ctimes%2010%5E3%5Ctimes%2010%5E5)
![17\times 10^{3+5}](https://tex.z-dn.net/?f=17%5Ctimes%2010%5E%7B3%2B5%7D)
![17\times 10^{8}](https://tex.z-dn.net/?f=17%5Ctimes%2010%5E%7B8%7D)
Now to write our answer in scientific notation, we need our 1st multiple between 1 and 10. So we will rewrite our expression as:
![1.7\times 10\times 10^{8}](https://tex.z-dn.net/?f=1.7%5Ctimes%2010%5Ctimes%2010%5E%7B8%7D)
![1.7\times 10^{1+8}](https://tex.z-dn.net/?f=1.7%5Ctimes%2010%5E%7B1%2B8%7D)
![1.7\times 10^{9}](https://tex.z-dn.net/?f=1.7%5Ctimes%2010%5E%7B9%7D)
Therefore, our required solution would be
.

Answer:
135
Step-by-step explanation
Turn 54% into a decimal so it would be like 0.54
Then multiply 250 by 0.54 to get 54% of the number.
For rational expressions, all real numbers can be used as inputs, except for those that make the denominator equal to 0 (since division by 0 is undefined).
Thus, the domain restrictions are values that turn the denominator into 0. Since you have (x + 2) (x - 1) as the denominator, then it means that:
For (x + 2), the value of x CANNOT be -2, as it will result into 0.
For (x - 1), the value of x CANNOT be 1 because their difference will have 0 as a result.
Therefore, the correct answers are:
b.) x = 1
c.) x = -2

Answer:
The correct statements are A & C.
Step-by-step explanation:
<u>Standard deviation:</u>
Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.
- A low standard deviation means that most of the numbers are close to the average.
- A high standard deviation means that the numbers are more spread out
Statement A is correct, City A's heights are more spread than City B's, because. City A's standard deviation is greater than City B.
Statement C is correct, because city A's mean is lesser than City B.
