Combination Formula: (n = distinct objects, r = how many you pick) n!/(r!(n-r)!
So n = 7, r = 5
n! = 7! = 5040
R! = 5! = 120
(n-r) = 2! = 2
120*2=240
5040/240 = 21
21 combinations!

Answer:
2 hours
Step-by-step explanation:
I substituted y for 126 and solved like so:
126 = 38x + 50
126 - 38x = 50
(126-126) - 38x = 50 - 126
-38x = -76
-38x/-38 = -76/-38
X = 2
There ya go! Hope this helps, good luck :)

The test statistic for the Goodness of fit test is:
For <em>k</em> independent samples this test statistic follows a Chi-square distribution with degrees of freedom (<em>k</em> - 1).
The sample size in this case is, <em>k</em> = 5.
The degrees of freedom is, (<em>k</em> - 1) = 4.
The level of significance is, <em>α</em> = 0.01.
The critical value of the test is:
**Use the Chi-square table.
Thus, the critical value is 13.277.
