Mathematics
1 answer:
const2013 [10]3 years ago
8 0

Answer:

See attachment

Step-by-step explanation:

Given

\begin{array}{ccccccc}{Marks} & {0-10} & {10-20} & {20-30} & {30-40} & {40-50}  & {50-60}\ \\ {Students} & {7} & {15} & {22} & {30} & {16} & {10} \ \end{array}

Required

The frequency polygon

We have:

\begin{array}{ccccccc}{Marks} & {0-10} & {10-20} & {20-30} & {30-40} & {40-50}  & {50-60}\ \\ {Students} & {7} & {15} & {22} & {30} & {16} & {10} \ \end{array}

First, we calculate the midpoint of each class

\begin{array}{ccccccc}{Midpoint} & {(0+10)/2} & {(10+20)/2} & {(20+30)/2} & {(30+40)/2} & {(40+50)/2}  & {(50+60)/2}\ \\ {Students} & {7} & {15} & {22} & {30} & {16} & {10} \ \end{array}

\begin{array}{ccccccc}{Midpoint} & {5} & {15} & {25} & {35} & {45}  & {55}\ \\ {Students} & {7} & {15} & {22} & {30} & {16} & {10} \ \end{array}

Lastly, we plot the midpoint against the frequency of students (see attachment)
