Given that Winnona took 5 tests and retake Test 5. So the mean score for this question is Total number of scores divide by Total number of tests is equals to 87 :

Let Test 5's score be x,

Let mean score be 87,

$\frac{95 + 85 + 96 + 97 + x}{5} = 87$

Next you have to solve the value of x :

$373 + x = 87 \times 5 \\ 373 + x = 435 \\ 373 + x - 373 = 435 - 373 \\ x = 62 \: \: \: scores$

Is 23/40 a rational or irrational number? I'm not sure how to solve this one.

Answer:

23/40 is a rational number

Step-by-step explanation:

an irrational number cannot be written as a fraction - with a finite end. An irrational number would be a repeating decimal
