Answer:
Size 50
Step-by-step explanation:
You should choose the larger sample size. This is because if you take the mean, it will help to cancel out outliers. For instance, most people exercise half an hour. With sample size of 10, there might be one person who doesn't exercise, thus dragging down the mean. A larger sample size would have a greater ratio of "average" people.

Answer:
240
Step-by-step explanation:
if 1 full rotation is 360 degrees than 1/3 rotation is 120 degrees so 2/3 must be 240 degrees
Answer:
Substitute (2) into (1):
Log both sides:
Divide by y on both sides:
2= y
y= 2 (proved)
Explanation:
• step 5: lg(m)^n= nlg(m)
• Step 6: lg(mn)= lg(m) +lg(n)
The slope is y2-y1/x2-x1 = 9-(-3)/8-(-4)=9+3/8+4= 12/12=1
So the slope is 1
