Answer:

<em>F test</em>

Step-by-step explanation:

<em>For any test using the F-distribution, a "F Test" is a capture-all word. In certain circumstances, as individuals speak about the F-Test, it is the F-Test to compare two variances that they actually talk about. </em>

Moreover, in a multitude of tests, the f-statistics is used such as regression analysis, the Chow test and the Scheffe test (a post-hoc ANOVA test).

One should be using Excel, SPSS, Minitab or some other form of software to run the experiment if you are running a F test.

<em><u>Steps include.</u></em>

  1. State the hypothesis of nullity and the counter hypothesis.
  2. Determine the value of F. The F value is determined using equation F = (SSE1 – SSE2/m)/SSE2/n-k, where SSE = square residual, m = number of constraints, and k = number of independent variables.
  3. Find the statistics for F (the critical value for the test). The F statistical formula is: F Statistics = group mean / mean variance of variances within the group.  
  4. The F Statistics can be found in the F-Table.  
  5. The Null Hypothesis is accepted or denied.

A ball is rolled at a velocity of 12m/sec.after 36 seconds,it comes to a stop what is the acceleration of the ball?
miv72 [106K]

acceleration of ball is \frac{-1}{3}\,\,m/sec^2

Step-by-step explanation:

Initial Velocity = 12m/sec

time = 36 s

Final Velocity 0 m/sec (ball comes to stop)

Acceleration= ?

The formula used to find acceleration is:

Acceleration=\frac{Final\,\,Velocity-Initial\,\,Velocity}{Time}

Putting values and finding acceleration:

Acceleration=\frac{Final\,\,Velocity-Initial\,\,Velocity}{Time}

Acceleration=\frac{0-12}{36}

Acceleration=\frac{-12}{36}

Acceleration=\frac{-1}{3}\,\,m/sec^2

So, acceleration of ball is \frac{-1}{3}\,\,m/sec^2

m_a_m_a [10]

Answer: 10

18 divide by 3 is 6 because you always divide first is this case

9-6+7 now solve straight across

9 minus 6 is 3 plus 7 is 10

Step-by-step explanation: Also

You are beautiful. You are amazing. You are wonderful. You are perfect just the way you are. Never worry about the way people think about you. Only worry if you like you. You are the most important person to yourself. Just be yourself. No can tell you who you can be. You are truly perfect just the way you are. Never tell yourself you are not good enough, you are enough. Never tell yourself "I'm ugly" you are beautiful. Never let yourself down.

The probability that a player will be asked a math question and then a music question is 0.03125

<h3>How to determine the probability?</h3>

The size of the sections are given as:

Music = 0.5

Sport = 0.5

Others = 1

So, the total size is:

Total = 0.5 + 0.5 + 1 + 1 + 1

Evaluate

Total = 4

The probability of asking a math question is:

P(Math) = 1/4 = 0.25

The probability of asking a music question is:

P(Music) = 0.5/4 = 0.125

The required probability is:

P(Math and Music) = P(Math) * P(Music)

This gives

P(Math and Music) = 0.25 * 0.125

Evaluate

P(Math and Music) = 0.03125

Hence, the probability that a player will be asked a math question and then a music question is 0.03125
