How do you find your percent after you get 100 percent on a test and the test is 60 percent of your grade?
[(100x60) + (Tx40)]/100=Average, where T is you average on the other 40% of your grade. Example: your grade average is 90 before the test. You get a 100 on the big test. [(100x60) + 90x40)]/100 = [6000 + 3600]/100 = 96
What is the average speed at t equals 20?
Assuming t is time, you need to know the distance traveled in time t. Then, divide the distance by time to obtain speed (velocity).
What is the t test used for?
The"t" test, (called the "small 't' test, to distinguish it from the large 'T' test) is a test for deviation from a known norm, using a smaller sample set than the one required by the large T test. It is said to have been developed by the head of quality control at the Guinness Brewery in Ireland.
Explain how to calculate average speed?
Average speed = d/t (distance covered in some period of time) divided by (the length of time to cover it)
Is a z test or t test used more often?
t test, because the z test requires knowing the population standard deviation and that's rare. The t test embodies an estimate of the standard deviation.
