Answer:
24x^2
Step-by-step explanation:
The Diameter of sphere is 2cm.
Step-by-step explanation:
Given,
Volume of sphere = 
Let,
diameter = d
As we know,
Volume of sphere = 
Therefore,

We know that,
Diameter = 2r
Diameter = 2*1
Diameter = 2 cm
The Diameter of sphere is 2cm.

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.
