Answer
X= -1
Step-by-step explanation:
<span> Given polynomial x^2+8x-48 = 0</span>
<span>x^2+12x-4x-48 = 0</span>
<span>x(x+12)-4(x+12) = 0</span>
<span>(x+12)(x-4) = 0</span>
<span>x+12 = 0</span>
Subtract 12 from each side.
<span>x+12-12 = 0-12</span>
<span>x = -12</span>
<span>and x-4 = 0</span>
Add 4 to each side.
<span>x-4+4 = 0+4</span>
<span>x = 4</span>
<span>Roots are -12,4.</span>
Answer:
I
Step-by-step explanation:
Because independent sample t-tests compare two completely different groups in a sample, which is what the researcher is attempting to do.
1)
LHS:

LHS = RHS. So, the statement is true
2)
LHS:

LHS not equal to RHS. So, the statement is false
3)
LHS:

LHS = RHS. So, the statement is true.
4)
LHS:

LHS = RHS. So, the statement is true.
First, you need convert the decimals into fraction
0.26 = 26/100 = 13/50
The next step would be drawing 50 small boxes on a piece of paper. Make it colorless.
The final stap would be giving 13 out of those 50 boxes with different color (such as black), and you're done
