Answer:
309 students
Step-by-step explanation:
Out of 600 students who complete the proficiency test, 423 were found to be proficient in reading, 398 were found to be proficient in math, and 512 were found to be proficient in either reading or math. How many were proficient in both reading and math?
We solve the above question using the formula below:
Where R = Proficiency in reading
M = Proficiency in maths
n ( R ∪ M) = n(R) + n ( M) - n ( R ∩ M)
n ( R ∪ M) = 512 students
n(R) = 423
n ( M) = 398
n ( R ∩ M) = ??
Hence:
512 = 423 + 398 - n ( R ∩ M)
n ( R ∩ M) = 423 + 398 - 512
= 821 - 512
= 309
The number of people proficient in both reading and math [n ( R ∩ M)] = 309 students

Answer:
The length of the given line segment is cm
Step-by-step explanation:
Given end points are (-3,2) and (5,-1)
To find the length of a line segment with these given end points
By using the distance formula we can calculate the length of a line segment
Let and be the two end points (-3,2) and (5,-1) respectively
Therefore units
Therefore the length of a given line segment is cm
