Answer:
D y=-1/2x+4
Step-by-step explanation:
use the order parir (4,2) x=4
y=-1/2*4+4
y=-2+4
y=2
The formula for the standard error is this:
σM = σ / √N
where
σM is the standard error
σ is the standard deviation
N is the number of samples
So,
σM = 0.45 / √50
σM = 0.0636 or 6.36%
The standard error is 0.0636
Answer:
Slope = 9/6
Step-by-step explanation:
Step 1: We have formula to find the slope if we are given two point.
<h3>slope =
</h3>
Given points (-1, -5) and (5, 4)
Here x1 = -1, y1 = -5 and x2=5 and y2 = 4
Step 2: Plug in those values into formula and simplify.
Slope = (4 - (-5)) / (5 - (-1))
= (4 + 5)/(5 + 1) -(-5)= 5 and -(-1) = 1
Slope (m) = 9/6

Hope you will understand this.
The domain and range of the given function are equal to (0, 3.85) and (0, 18.75) respectively.
<h3>How to calculate the domain of the function?</h3>
In this exercise, you're given the following function h(t) = -4.87t² + 18.75t. Next, we would equate the function to zero (0) to determine its domain as follows:
0= -4.87t² + 18.75t.
4.87t(-t + 3.85) = 0
t = 0 or t = 3.85.
Therefore, the domain is 0 ≤ t ≤ 3.85 or (0, 3.85).
<h3>How to calculate the range of the function?</h3>
h(t) = -4.87t² + 18.75t
h(t) = -4.87(t² - 3.85t + 3.85 - 3.85)
h(t) = -4.87(t - 1.925)² + 18.05
Therefore, the range is 0 ≤ h ≤ 18.05 or (0, 18.75).
