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).
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)
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.
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.
Derive the equation for instantaneous average acceleration vector?
The instantaneous average acceleration vector is given by the derivative of the velocity vector with respect to time. Mathematically, it can be written as ( \overrightarrow{a}(t) = \lim_{{\delta t \to 0}} \frac{{\overrightarrow{v}(t + \delta t) - \overrightarrow{v}(t)}}{{\delta t}} ), where ( \overrightarrow{a}(t) ) is the acceleration vector at time ( t ) and ( \overrightarrow{v}(t) ) is the velocity vector at time ( t ).
Derive the equation for average value of DC?
The equation for the average over time T is integral 0 to T of I.dt
What equation relates travel time t to average speed?
t+v+d
Does T-Mobile have good pre-paid phone rates?
T-Mobile's pre-paid phone rates are on par with the national average.

Is T test similar to Z test?
no t test is similar to z test because t test ie used for unknown observation and z is for the medicne
What are the Limitations of the t-test in statistics?
Two limitations of a t-test are you can only use one factor at a time and you can only use two levels at a time. You have to watch out for the Type 1 error because it increases with simultaneous tests.
What is the formula to calculate average speed of answer?
If n answers are given in t seconds then the average speed of answer is n/t answers per second. t could be a longer time interval, if appropriate.
State the equation linking average speed distance moved and time taken?
The equation linking average speed (v), distance moved (d), and time taken (t) is: v = d/t. This equation represents the average speed as the ratio of the total distance traveled to the total time taken to cover that distance.
How can you figure out somethings average speed?
Measure the total distance travelled (d) over a period of time (t). Then, the average speed is d/t in the appropriate units.
How do you calulate average velocity?
Average velocity is calculated by dividing the total displacement of an object by the total time taken to make that displacement. The formula is: average velocity = (final position - initial position) / total time. This gives a measure of the overall rate at which an object is changing its position over a specific time interval.
