Question

you answered 95% of the questions correctly on a 40 question test how many questions did you answer incorrectly

Answer 1

2 questions

Step-by-step explanation

Step 1

convert 95% in decimal form

95 % means that 95 out of 100 answered were correctly answered

`95\text{ \% }\Rightarrow(95)/(100)=0.95`

in other words, to find the 95 % of any number you have to multiply the numbr by 0.95

then

95 % of 40 is

`95\text{ \% of 40 =0.95}\cdot40=38`

it means 38 of 40 questions were correctly answered.

Step 2

now, the wrong aswer is the difference

`\begin{gathered} \text{wrong answer=total question-correct answer} \\ w\text{rong asnwer=40-38=2} \end{gathered}`

Hence,you answered 2 questions incorrectly.

I hope this helps you
