Using it's formula, it is found that Val's margin of error is of 9.8 pounds.
<h3>Margin of error:</h3>
The margin of error is given by the following equation:
In which:
- s is the standard deviation.
In this problem:
- The standard deviation is of 50, hence
.
- Val weighed 100 cows, hence
.
Then:
Val's margin of error is of 9.8 pounds.

I have no idea what to do. We have to do the same stuff too

-x + 5y = 4 ⇔ slope 1/5, y-intercept 4/5
5y - x = 15 ⇔ slope: 1/5, y-intercept: 3
2y - 3x = 7 ⇔ slope: 3/2, y-intercept: 7/2
2y = 5x + 7 ⇔ slope: 5/2, y-intercept: 7/2
<u>Explanation</u>
-x + 5y = 4
5y = x + 4
y = (1/5)x + 4/5 slope 1/5, y-intercept 4/5
5y - x = 15
5y = x + 15
y = (1/5)x + 3 slope: 1/5, y-intercept: 3
2y - 3x = 7
2y = 3x + 7
y = (3/2)x + 7/2 slope: 3/2, y-intercept: 7/2
2y = 5x + 7
y = (5/2)x + 7/2 slope: 5/2, y-intercept: 7/2

Answer:
c) l x - 5 l - 4
Step-by-step explanation:
when you're graphing functions whatever is inside the paranthesis, square root or absolute value determines whether you go left or right, if its a negative you go to the right, if its positive you go to the left. So the opposite of what you would expect it to go
in this instance its - 5, so you go 5 units to the right
and the number outside determines if you go up or down, in this question its - 4 so you go down 4 units
