Answer:
Option A is correct.
y = 35.4 bushels per acre when rainfall = 7.1 inches
Step-by-step explanation:
An image of the steps to obtain the equation that relates x to y is attached to this answer.
n = number of variables = 9
μₓ = mean of variable x (rainfall in inches)
μᵧ = mean of variable y (yield in bushels per acre)
σₓ = standard deviation of variable x (rainfall in inches)
σᵧ = standard deviation of variable y (yield in bushels per acre)
y = 4.379x + 4.268
when x = 7.1
y = 4.379(7.1) + 4.268 = 35.3589 = 35.4 bushels per acre.
Answer: 342.5 miles
Step-by-step explanation:
Distance = Speed x Time
<u>Speed(mph) </u> <u>Time(hr)</u> <u>Distance(miles)</u>
55 x 3.5 = 192.5
60 x 2.4 = <u>150</u>
<u>Total Distance (miles) =</u> 342.5 miles
Step-by-step answer with explanations:
Recall that a coordinate pair such as (5,-1) has two components.
The first (5, -1) means that the point is situated at x=5.
The second (5, -1) means that the point is situated at y=-1.
Now, a <em>horizontal</em> line through (5,-1) means that ALL points on the line have y-coordinate equal to -1, so that any point with y=-1 will lie on this horizontal line. An example would be (-2,-1).
A <em>vertical</em> line through (5, -1) means that ALL points on the line have x-coordinate equal to 5, so that any point with x=5 will lie on this vertical line. An example would be (5,4).
