Here's your original problem:
2) To receive a license to sell insurance, an insurance account executive must answer correctly 70% of the 250 questions on a test. Nicholas Mosley answered 177 questions correctly. Did he pass the test?
First, let's figure how many right answers are passing on this test.
0.7 * 250 = 175
To pass this test, students need at least 175 correct answers.
Nicholas answered 177 correctly.
Therefore he passed the test because he has two more right answers than is needed for passing it.
Thanks for helping me with this question:)
You're welcome. :-)
To determine whether Nicholas passed the test, we need to compare the number of questions he answered correctly to the passing threshold.
The first step is to calculate the passing threshold. We can do this by finding 70% of the total number of questions on the test, which is 250.
70% of 250 = 0.7 * 250 = 175
Therefore, in order to pass the test, Nicholas needs to answer at least 175 questions correctly.
Next, we compare the number of questions Nicholas answered correctly, which is 177, to the passing threshold of 175.
Since Nicholas answered more questions correctly than the passing threshold, he has met the requirement to pass the test.
Therefore, Nicholas has passed the test because he answered two more questions correctly than is needed for passing.
