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.
Let the number of Go-go scooter to be produced be x and that of Whip scooter y, then
Maximize: R = 3200x + 5000y
subject to:
x + y ≤ 120
3x + 6y ≤ 600
The corner points of the constraints are (0, 0), (0, 100), (40, 80), (120, 0)
For (0, 0): R = 0
For (0, 100): R = 3200(0) + 5000(100) = 500,000
For (40, 80): R = 3200(40) + 5000(80) = 528,000
For (120, 0): R = 3200(120) + 5000(0) = 384,000
Therefore, for maximum revenue, they should produce 40 Go-go scooters and 80 Whip scooters.
Answer:
1. Yes (side angle side)
2. I don’t know for sure but I’m thinking no
3. No
Step-by-step explanation:
I would think it to be A because 8/12 can be simplified into 3/4
3x/4+3=20
<=> 0.75x +3 =20
<=> 0.75x = 17
<=> x = 68/3
