To find the original amount, you do the amount she got correct divided by (1 minus the percentage). 

Let P = amount of problems on the test. 

P = 14 / (1 - 0.56) 
= 14/ 0.44
≈ 31.818 repeating. 

You can have part of a question (in this math, that is. Partial credit IRL exists) so we round to the nearest whole question, 32. 

The test had 32 questions.

56% = 14 questions

1% = 14 ÷ 56 = 0.25 questions

100% = 0.25 x 100 = 25 questions

Answer: 25 questions.

Answer:

P(green)+P(yellow)=\frac{3}{8}+\frac{1}{8}

P(green)+P(yellow)=\frac{1}{4}+\frac{1}{4}

P(green)+P(yellow)=\frac{3}{7}+\frac{1}{14}

Step-by-step explanation:

The given probabilities are:

P(red)=\frac{2}{7}

P(blue)=\frac{3}{14}

Their sum is P(red)+P(blue)=\frac{2}{7}+\frac{3}{14}

The probabilities that will complete the model should add up to \frac{1}{2} so that the sum of all probabilities is 1.

P(green)+P(yellow)=\frac{2}{7}+\frac{2}{7}\ne\frac{1}{2}

P(green)+P(yellow)=\frac{3}{8}+\frac{1}{8}=\frac{1}{2}

P(green)+P(yellow)=\frac{1}{4}+\frac{1}{4}=\frac{1}{2}

P(green)+P(yellow)=\frac{5}{21}+\frac{11}{21}\ne\frac{1}{2}

P(green)+P(yellow)=\frac{3}{7}+\frac{1}{14}=\frac{1}{2}
