The slope for the relationship between the price and the quantity of ice cream sold is -$0.067 per unit

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept.

Let y represent the price (vertical axis) and x represent the quantity.

The slope = ($3 - $4)/(35 - 20) = -$0.067 per unit

The slope for the relationship between the price and the quantity of ice cream sold is -$0.067 per unit

Anna [14]

Answer:

-0.503

Explanation:

Z-score is expressed as:

Z-score = x - μ/σ

Given the following

x = 28.5413

μ = 30

σ = 2.9

Z-score = 28.5413-30/2.9

Z-score = -1.4587/2.9

Z-score = -0.503

Hence the z-score for the distribution is -0.503
