Answer:

15 students

Step-by-step explanation:

The fraction of students who will repeat the exam is:

1-\frac{6}{9}

=\frac{9}{9} -\frac{6}{9} =\frac{3}{9}

simplified is:

\frac{1}{3}

Extract this fraction of 45:

45(\frac{1}{3} )=\frac{45}{3} =15

Hope this helps

The relative frequency for the class with lower class limit 31 is 8.57%.

<h3>How to calculate the frequency?</h3>

It should be noted that the lowrr class frequency is 31 in this case.

Therefore, the relative frequency for the class with lower class limit 31 will be:

= 3/(6+4+4+9+3+9) × 100

= 3/35 × 100

= 8.57%

Therefore, the relative frequency for the class with lower class limit 31 is 8.57%.

How do i estimate quotients 933 divided by 3
Maurinko [17]
K, so
remember that \frac{a+b+c}{d} = \frac{a}{d}+ \frac{b}{d}+ \frac{c}{d}
so
\frac{933}{3}=\frac{900+30+3}{3} = \frac{900}{3}+ \frac{30}{3}+ \frac{3}{3}   = 300+10+1=311
