Did you ever find the answer because i need it !
The t-distribution has n - 1 degrees of freedom, where n is the sample size.
In this case n = 20. So the required number of degrees of freedom is:
20 - 1 = 19.
The answer is: 19 degrees of freedom.
Answer:
x = -20
Step-by-step explanation:
-⅗(15x - 30) = 198
Multiply each side by 5
-3(15x - 30) = 990
Distribute the -3
-45x + 90 = 990
Subtract 90 from each side
-45x = 900
Divide each side by -45
x = -20
<em>Check:
</em>
-⅗[15(-20) - 30] = 198
-⅗(-300 - 30) = 198
-⅗(-330) = 198
198 = 198
