Step-by-step explanation:
The predicted useful life of a brand A cutting tool when the speed is 45 meters per minute is 1.2 to 5.5 hours.
The predicted useful life of a brand B cutting tool when the speed is 45 meters per minute is 3.4 to 5.4 hours.
The prediction interval for brand A is larger than the prediction interval for brand B because the estimated standard error of y^ is different for the two intervals.
The prediction intervals are both larger than the corresponding confidence intervals.
The standard error for the estimated mean value of y is smaller than the standard error for the predicted value of y.
The predicted useful life of a brand A cutting tool that is operated at 100 meters per minute is -0.59 hours
The actual predicted useful life of a brand A cutting tool when the speed is 100 meters per minute is 0.0 to 2.3 hours.
Check the picture below.
make sure your calculator is in Degree mode.
If you are asking for the slope it is a zero slope because...
2-2 equals 0 and you don't need to solve the bottom because the top is a zero
but a horizontal slope is when the zero is on the bottom.
btw- I guarantee I am right because i am a Indian. My wisdom comes from God. Jesus Christ!!!!:):):)
Answer:
You cant solve this problem
Step-by-step explanation:
20+(-3.05)+(-9.8)=20-3.05-9.8=7.15
