Nick is doing some math exercises on a website called Khon Academy. In Khon Academy, you have to get at least 70%, percent of the problems in an exercise right in order to gain proficiency.
So far, Nick answered one question, and he didn't get it right. Suppose he answers 75%, percent of the following questions correctly and gains proficiency in the exercise.
Write an inequality in terms of that models the situation.

Respuesta :

Answer:

0.75q/q+1 greater than or equal to .7

Step-by-step explanation:

Let us consider q as the number of questions he answered after the first one he gets [tex]75[/tex]% of these correct [tex]75\%=0.75[/tex].

This gives us [tex]0.75q[/tex].

He has already answered [tex]1[/tex] questions and answers q more, this gives us a total of [tex]q+1[/tex].

So, he gains proficiency, the cut-off was [tex]70\%=0.70[/tex].

Out inequality would be then,

                                   [tex]0.75q\geq 0.70(q+1)[/tex]

Hence, The inequality in terms of the given situation is [tex]0.75q\geq 0.70(q+1)[/tex]

What is Inequality ?

The word inequality means a mathematical expression in which the sides are not equal to each other. Basically, an inequality compares any two values and shows that one value is less than, greater than, or equal to the value on the other side of the equation.

How do you find an inequality?

To solve an inequality, isolate the variable on one side with all other constants on the other side. To accomplish this, perform opposite operations to manipulate the inequality. First, isolate the x by multiplying each side by two. Whatever you do to one side you must also do to the other side.
