Answer:
The student had a total of 25 questions on his test.
Step-by-step explanation:
Given that:
Number of questions answered correctly in the test = 20
Percentage scored in the test = 80%
Let,
x be the total number of questions on test.
We know that 80% of the test is 20 questions, therefore,
80% of x = 20
Dividing both sides by 0.8
Hence,
The student had a total of 25 questions on his test.

<span>The multiplicity of a zero of a polynomial function is how many times a particular number is a zero for a given polynomial.
For example, in the polynomial function
, the zeros are 0 with a multiplicity of 1, -4 with a multiplicity of 2, and 2 with a multiplicity of 3.
Although this polynomial has only three zeros, we say that it has six zeros (or degree of 6) counting the <span>multiplicities.</span></span>
