Answer:
c. The circuit is most likely defective, but it might be good
Step-by-step explanation:
A hypothesis test is being conducted, where electrician uses an instrument to test whether or not an electrical circuit is defective.
The instrument sometimes malfunctions, it fails to detect that a circuit is good and working.
Null hypothesis = H₀ = Circuit is good and works (not defective)
Alternative hypothesis = Ha = Circuit is not good and doesn't work (defective)
If the electrician rejects the null hypothesis, then it means that the circuit is most likely to be defective, but it might be good since the instrument sometimes malfunctions and fails to detect that the circuit is good. Therefore, option C is the correct option.
Answer:
B. 1,500’
Step-by-step explanation:
Given;
dimension of the rectangular house, = 35’ x 40’
The actual total linear footage of lumber needed = 35’ x 40’ = 1,400'
The rough estimate should be greater than the actual estimate in 100s;
rough estimate = 1,400' + 100' = 1,500'
Therefore, the rough estimate of the total linear footage of lumber needed is 1,500'.
Answer:
y=-12x-9
Step-by-step explanation:
plug the value of m and b in the equation:
-y=12x+9
divide negative 1
y=-12x-9
It would be > cause it is a smaller fraction which makes the decimal a bigger number
Hope it helps
So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b".
For a. I got x=7.
