Each person rode 2.9 miles and A total of 8 ones and 7 tenths are shaded to model the total length of the race. The shading is equally divided into 3 groups to model the 3 riders. And each group has 2 ones and 9 tenths shaded to model the distance each person rode
Given:
The objective is to find the slope of the straight line.
Explanation:
The general equation to find the slope is,

Let's consider two coordinates from the graph.

On plugging the values in the equation of slope,

Hence, the slope of the straight line is -5.
The height of the tank is 12 inches
The Z-score (z) is calculated according to the formula: z = (x - μ) / σ
Where: x is the raw score value, μ is the mean of the population, σ is the standard deviation of the population.
x = 80, μ = 5, σ = 4
z = (80 - 5) / 4
z = 75 / 4 = 18.7500
Z-score is 18.7500
