The line legment has the length of 36 cm. It was divided into four unequal parts. If the distance between the midpoints of the f
goldenfox [79]
Hello.

 the line segment is 36 cm and the distance between the midpoints of the first and the fourth parts is 30 cm, this means that the sum of the lengths of the first and the last part is 

2(36 - 30) = 2(6) = 12 cm.

Thus, the sum of the length of the second and the third part is 36 - 12 = 24 cm.
Therefore, the distance between the midpoints of the second and the third parts is 24 / 2 = 12 cm.

The modal and mean mark of the frequency distribution is 5 and 4.83 respectively.

<h3>Mean and mode</h3>

Mode refers to a mark which reoccurs most in a frequency distribution.

  • Modal mark = 5

The total number of students who wrote the test = 2 + 3 + 4 + 6 + 10 + 4 + 3 + 2 + 1 + 1

= 36 students

Mean mark = Total mark / Total students

= (2×1) + (3×2) + (4×3) + (6×4) + (10×5) + (4×6) + (3×7) + (2×8) + (1×9) + (1×10) / 36

= (2+6+12+24+50+24+21+16+9+10 / 36

= 174/36

= 4.83333333333333

Approximately,

Mean mark = 4.83

If 25% of students failed,

Number of students who failed = 25% of 36

= 25/100 × 36

= 0.25 × 36

= 9 students.

Marco was shopping for markers and lead pencils. The cost of markers is $4, and the cost of each lead pencil is $3. If Macro can
never [62]

This shows that Marco can buy at most 5 pencils

<h3>Inequalities</h3>
  • Let the price of each pencil Marco can  buy be "x"

If the cost of markers is $4, and the cost of each lead pencil is $3 with at most $15 spent, hence;

  • 4 + 3x ≤ 15

Subtract 4 from both sides

3x  ≤ 15

x ≤ 15/3

x ≤ 5

This shows that Marco can buy at most 5 pencils
