Answer:
A) 7
B) 32
C) 39
Step-by-step explanation:
Degree of freedom is a means of checking how many values that are free to vary, while using a statistical method.
a) since the experiment has a single factor with eight critical values. Therefore;
C - F = degree of freedom among the group variation
8 - 1 = 7
b) The degree of freedom can be calculated, if the number of data; Therefore, number of data is;
N = 8 × 5 = 40
Then the degree of freedom in determining within group variation,
N - C Therefore;
40 - 8 = 32
C) The degree of freedom in determining the total variation is,
N - 1
40 - 1 = 39
We know that the formula for calculating distance is:
distance d = velocity v * time t
Calculating for each interval:
1: 25 km/hr for 4 minutes
d1 = (25 km / 60 min) (4 min) = 1.67 km
2: 50 km/hr for 8 minutes
d2 = (50 km / 60 min) (8 min) = 6.67 km
3: 20 km/hr for 2 minutes
d2 = (20 km / 60 min) (2 min) = 0.67 km
The total distance covered is:
d = d1 + d2 + d3
d = 1.67 + 6.67 + 0.67
d = 9 km
The average speed is:
s = 9 km (1000 m / km) / (14 min * 60 s / min)
s = 10.72 m / s
X = -3, 8
hope this helps
The graph on the top right is non linear bc it breaks pattern in y column
9 - 8x = 35
subtract 9 from both sides
-8x = 26
divide both sides by -8
x= -26/8
you can simplify this to -13/4
