Hello, what you are looking for is the term z-score. z-score is the standardized score that has been developed for statistics to compare data from different scales. By using the mean and standard deviation of the data values, a z-score is calculated and comparisons can be deduced even if the two data sets have different scales.

For example, if a z-score is 1.33, then it is 1.33 standard deviations from the mean. This result is more typical compared to a z-score of 3 meaning that it is 3 standard deviations from the mean.

Solve for y.<br> K=2yz<br> plzz hurry

Murljashka [212]

Answer:

y = K/(2z)

Step-by-step explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Divide 2z from both sides:

(K)/2z = (2yz)/2z

y = K/(2z)

y = K/(2z) is your answer.

Let the velocity of a particle be given by v(t) = 2t+a.(a) Find the number a such that the average value of v(t) on the interval

denis-greek [22]

Answer:

The velocity is v(t) = 2*t + a

a) we want to find the average velocity betwen t = 0 and t = 1.

We can do this as:

Average = (v(1) + v(0))/2 = (2*1 + a + 2*0 + a)/2 = 1 + a

b) now we want to find the total distance traveled in the time lapse from t = 0 to t = 4.

For this we can see the integral:

$d = \int\limits^4_0 {2*t + a} \, dt = 4^2 + a*4 - 0^2 - a*0 = 4^2 + a*4 = 16 + a^2$
