Carlos plotted the points (-4,-4) and (0, 3) and connected them with a line, as shown below.
1 answer:
Answer:
The slope between the two points is 7/4
Step-by-step explanation:
<u>Slope of a Line</u>
Suppose we know a line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
The points plotted by Carlos are (-4,-4) and (0,3), thus the slope is:
The slope between the two points is 7/4

Answer:
The z-score for an income of $2,100 is 1.
Step-by-step explanation:
If X N (µ, σ²), then
, is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z
N (0, 1).
The distribution of these z-variate is known as the standard normal distribution.
Given:
µ = $2,000
σ = $100
<em>x</em> = $2,100
Compute the <em>z</em>-score for the raw score <em>x</em> = 2100 as follows:
Thus, the z-score for an income of $2,100 is 1.
