Given:

Total number of students = 20

The marks of the students are 40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37 and 40.

To find:

The frequency distribution table with class size 10.

Solution:

We have, the marks of 20 students.

40, 22, 36, 27, 30, 12, 15, 20, 25, 31, 34, 36, 39, 41, 43, 48, 46, 36, 37, 40

Here,

Minimum value = 12

Maximum value = 48

We nee class intervals of size 10. So, the required class intervals are 10-20, 20-30, 30-40, 40-50. In these intervals, lower limit is excluded but the upper limit included.

The required frequency distribution table is

Class intervals Marks Frequency

10-20 12, 15 2

20-30 22, 27, 20, 25 4

30-40 36, 30, 31, 34, 36, 39, 36, 37 8

40-50 40, 41, 43, 48, 46, 40 6

Total 20

Therefore, the frequency distribution table is

Class intervals: 10-20 20-30 30-40 40-50 Total

Frequency : 2 4 8 6 20

The slope of the line below is 2. Use the coordinates of the labeled point to

Alexus [3.1K]

Answer:

The equation of line passing through point (3 , 10) with slope 2 is y = 2 x + 4 .

Step-by-step explanation:

Given as :

The slope of a line = m = 2

The line is passing through point = $x_1$ , $y_1$ = 3 , 10

Now, Equation of line in point- slope form

y - $y_1$ = m × (x - $x_1$ )

Or, y - 10 = 2 × (x - 3)

Or, y - 10 = 2 × x - 2 × 3

Or, y - 10 = 2 x - 6

Or, y = 2 x - 6 + 10

Or, y = 2 x + 4

So, The equation of line y = 2 x + 4

Hence, The equation of line passing through point (3 , 10) with slope 2 is y = 2 x + 4 . Answer
