In a math class with 26 students, a test was given the same day that an assignment was due. There were 18 students who passed the test and 16 students who completed the assignment. There were 14 students who passed the test and also completed the assignment. What is the probability that a student who passed the test did not complete the homework?

Ans : 4 / 26 .

Step-by-step explanation:

No of students who passed the test = 18

No of students who passed the test and completed the assignment = 14

No of students who passed the test but did not complete the examination

= 18 - 4 = 4

Total no of students = 26

Required probability = 4 / 26 .

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
