Because algebra means finding the unknown
it is usually used in real life
for example if if 1/2 of the legnth of a line is 8 then what is the legnth
so then 1/2 x=8 and that is algebraic
since it has x, or an unknown in it, it is an algebraic expression

Answer:
The confidence level for a confidence interval of 46.4% to 47.6% is 99.7%.
Explanation:
First of all, the choices for this question are missing so I will include the ones I found for this exact question. The missing options are as follows:
A. 85% B. 95% C. 68% D. 99.7%
When it comes to statistics, a confidence interval (CI) is a type of interval estimate of a population parameter. Statistics is all about drawing conclusions in the face of uncertainty. Whenever you take a sample, you can’t be completely certain that your sample truly reflects the population it’s drawn from.
In conclusion, from the choices presented, the best option is the last one. Option D.
All values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1
<h3>How to graph the inequality on a number line?</h3>
The inequality expression is given as:
2x+2/x+7 >= 0
Multiply both sides by x + y
2x+2 >= 0
Subtract 2 from both sides
2x > -2
Divide both sides by 2
x >= -1
Hence, all values of x that satisfy 2x+2/x+7 >= 0 are represented as x >= -1
See attachment for the number line of x >= -1
