Answer:
A= y= -2x+7.
B= y= -x+ 6
Step-by-step explanation:
The linear equation is y=mx+b
A= y= -2x+7.
-2 represents he slope and 7 represents the y intercept.
B= y= -x+ 6
- is the slop and 6 is the y intercept.
Hope this helps :)
Answer:
y = x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (4, 5) ← 2 points on the line
m = =
The line crosses the y- axis at (0, 2 ) ⇒ c = 2
y = x + 2 ← equation of line
Answer:
<h2>69.5</h2>Step-by-step explanation:
Given the confidence interval of the heights of american heights given as (65.3,73.7);
Lower confidence interval L = 65.3 and Upper confidence interval U = 73.7
Sample mean will be the average of both confidence interval . This is expressed mathematically as
Hence, the sample mean is 69.5
