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.
Answer:
D) J
B) point Q
Step-by-step explanation:
we know that the ginipigs are only given 80 in total. that means 80 is 100%
40÷80*100=50%
20÷80*100=25%
10÷80*100= 12.5%
10÷80*100= 12.5%
all this together is 100%
meaning the best answer is
Q is the only place that = -1/2
Rate of Daniel - x:
4.95 (40 ÷ 9 + x) = 40
22 + 4.95x = 40
4.95x = 18
x = 40 ÷ 11
Time for Paul to gather 40 bushels:
= 40/(40 ÷ 11)
= 40(11 ÷ 40)
= 11
