The computation of the data shows that the standard error is 0.015.
<h3>How to calculate the standard error?</h3>
From the information, the following can be deduced:
Number of students n = 49
Randomly selected students = 0.794
The standard error will be:
= 0.105/✓49
= 0.105/7
= 0.015
In conclusion, the standard error is 0.015.

Answer:
x=2
Step-by-step explanation:
hello :
3 ln 2+ln 8=2 ln(4x)
for x > 0 : ln(2^3)+ln8 = ln(4x)²
ln8² = ln(4x)² because ; 2^3 = 8
4x=8
hence : x=2

Answer:
C. 5x^2(x - 3)(x + 7)
Step-by-step explanation:
When 5x^2 is factored out, you have ...
5x^2(x^2 +4x -21)
To factor the remaining quadratic, you need two numbers with a sum of 4 and a product of -21. Those would be 7, -3. This tells you the fully factored form is ...
5x^2(x -3)(x +7) . . . . matches choice C
I’m 99/100% sure it’s 15%
D, 6/16 square foot. This is because 8 and 4 and 2 all can go into 16 more simply than 32.
