19. v/2 = 2 1/30

Turn mixed number(s) to improper fraction(s).
v/2 = 61/30

Multiply both sides by 10.
v/2 × 10 = 61/30 × 10

Simplify.
5v = 61/3

Divide both sides by 5.
5v ÷ 5 = 61/3 ÷ 5

Simplify.
v = 61/15

61/15 or if you want it as a mixed fraction, it would be 4 1/15.

A set of N = 20 exam scores has a mean of m = 50. The instructor discovered that an error was made grading one exam, so 20 point
tatuchka [14]

Answer:

The new mean for the exam scores is 51

Step-by-step explanation:

the mean can be calculated using the formula

mean of scores = \frac{Sum total    of scores}{Number of students}

before the 20 points was added, the mean of the score was = 50.

Inserting this into the formula, we have:

50 = \frac{Sum total}{20 students}

from this, we can compute the sum total of the scores as

sum total = 50 × 20 = 1000

when the extra 20 marks is added, the sum of the entire scores will be changed to 1000 + 20 = 1020.

Hence the new mean will be computed as (New Sum total of scores / Number of students)

= \frac{1020}{20} = 51.

∴ The new mean of the scores is = 51
