Answer with explanation:
Number of second grade students who are considered for sample =1414
Number of words that is being read in a Minute = 9292 words per minute
If number of students will be more than half of 1414, that is if, they can read or their reading rate is more than 9292 words per minute, then we can say that the sample chosen is Appropriate.
⇒Required Probability,that sample of 1414 students can read 9292 words per minute
![=\frac{707+x}{1414} \text{Where }, [1 \leq x\leq 707]](https://tex.z-dn.net/?f=%3D%5Cfrac%7B707%2Bx%7D%7B1414%7D%20%5Ctext%7BWhere%20%7D%2C%20%5B1%20%5Cleq%20x%5Cleq%20707%5D)
Your answer is very close to being correct; however, the true answer is actually
without any parenthesis needed around the fraction. Notice how there is no (x) at the end.

Answer: x=5
Simplifying
5(x + -2) = 15
Reorder the terms:
5(-2 + x) = 15
(-2 * 5 + x * 5) = 15
(-10 + 5x) = 15
Solving
-10 + 5x = 15
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '10' to each side of the equation.
-10 + 10 + 5x = 15 + 10
Combine like terms: -10 + 10 = 0
0 + 5x = 15 + 10
5x = 15 + 10
Combine like terms: 15 + 10 = 25
5x = 25
Divide each side by '5'.
x = 5
Simplifying
x = 5
