Question

4) In a clinical test with 2353 subjects, 1136 showed improvement from the treatment.

Answer 1

Answer:

1217

Step-by-step explanation:

Given

$Subjects = 2353$

$Improvement = 1136$

Required

The number that didn't improve --- missing from the question.

Let the unimproved be represented as x.

So, we have:

$x + Improvement = Subjects$

Substitute known values

$x + 1136 = 2353$

Solve for x

$x =- 1136 + 2353$

$x =1217$
