Answer:

9/7, 1/6, -3, 4/5

Step-by-step explanation:

Use the $gradient =\frac{rise}{run}$ formula to solve this.

4: $gradient = \frac{14-5}{8-1} = \frac{9}{7}$

5: $gradient = \frac{10-9}{2-(-4)} = \frac{1}{6}$

6: $gradient = \frac{-5-4}{6-3} = \frac{-9}{3} = -3$

7: $gradient = \frac{-1-(-5)}{7-2} = \frac{4}{5}$

he numbers of regular season wins for 10 football teams in a given season are given below. Determine the range, mean, variance

Naddik [55]

Answer:

Range = 13

Mean = 8.4

Variance= 21.24

Standard deviation= 4.61

Step-by-step explanation:

2, 10, 15, 3, 13, 9, 14, 7, 2, 9

For the range

Let the set of data be arranged inn ascending order

Range= higehest value- lowest value

Range = 15-2

Range= 13

For the mean

Mean = (2+2+3+7+9+9+10+13+14+15)/10

Mean = 84/10

Mean = 8.4

For variance

Variance=((2-8.4)²+(2-8.4)²+(3-8.4)²+(7-8.4)²+(9-8.4)²+(9-8.4)²+(10-8.4)²+(13-8.4)²+(14-8.4)²+(15-8.4)²)/10

Variance= (40.96+40.96+29.16+1.96+0.36+0.36+2.56+21.16+31.36+43.56)/10

Variance= 212.4/10

Variance= 21.24

Standard deviation= √variance

Standard deviation= √21.24

Standard deviation= 4.609

Approximately = 4.61
