= = 0.3195 ≅ 0.31
Proportion estimate ( p ) = 0.31
∴ The proportion of new car buyers who prefer foreign cars -> 0.31
Answer:
Step-by-step explanation:
We have:
And we want to find the value of x such that the expression is positive. So, we can write this as the following inequality:
Solve for the inequality. First, we can solve for the zeros like a normal quadratic. So, pretend the inequality is with an equal sign:
Zero Product Property:
On the left, subtract 5.
On the right, add 1.
So, our zeros are:
Since our inequality is a <em>greater than</em>, our answer is an "or" inequality with our answer being all the values to the <em>left</em> of our lesser zero and all the values to the <em>right </em>of our greater zero.
So, our solution is:
And we're done!
The table is shown below in the attached picture.
The grand total is the bottom rightmost cell, yellow in color.
12th graders AND likes specialty cold drinks is the cell colored green.
These 137 people are p% of the total. To get the value of p, we will divide this number (137) by grand total (750) and multiply by 100 to get the value.
%.
Rounded to the nearest percent, it is 18%. Answer choice D is correct.
