Question

A student earned a grade of 80% on a math test that had 20 problems. How many problems on this test did the student answer correctly?What is the value of (0.3)4 ?

Answer 1

Answer: 16 questions

Explanation:

To find how many problems the student correctly answered on the test, we can turn 80% into a fraction.

`(80)/(100) =(16)/(20)`

The student answered 16 questions correctly.

The value of (0.3)^4 is 0.0081.

Unless you mean 0.3*4, then it is 1.2.
