Answer:
Option B) 9.1
Step-by-step explanation:
We are given the following in the question:
Average score = 490.4
Standard deviation = 63.7
Sample size, n = 49
Formula:
Putting values, we get,
Standard error =
Thus, the correct answer is
Option B) 9.1
Answer:
The answer is , or the first option.
The last option isn't correct for this answer, even though it is correct mathematically. This is because it wants the fully simplified version, so the 5o squared would turn into a 5 and a 2, with the 5 multiplying the -6, and the 2 remaining underneath the square root.

Answer:
infinitely many solutions (infinite solutions)
Step-by-step explanation:
2y - 8 = 6x
+8 +8
-------------------------------
2y = 6x + 8
= +
-------------------------------
y = 3x + 4
Because 3x + 4 = 3x + 4, there are infinitely many solutions to this system of equations. This is because they're the exact same equations. Any substitution for x will give you a true statement to y when compared to the other equation.
