Answer:
3.85
Step-by-step explanation:
To find the absolute value, you are finding the magnitude of your value, so your answer would be the same value without the negative sign.
Step-by-step explanation:
Use midpoint formula ,
x = 12 , y = 4
midpoint of line segment is (12,4)
This is a statistics problem on permutation and combination. To differentiate this, permutation involves on the arrangement in which order doesn't matter. For combination, order matters.
For example, if you arrange A, B and C, for permutation it could be AB, BA, CA, AC, BC and CB. But for combination, it would just be AB, AC and BC.
So, in this problem where he is asked to arrange 8 jars in which order doesn't matter. It is permutation. You can solve this just by calculator. The formula would be nPr, where n is the total number of items while r is the number of items to be sorted. Thus,
nPr = 10P8 = 1, 814,400
Thus, the answer is B.
Answer:
This equation has no real solutions, because the discriminant is less than zero.
Step-by-step explanation:
no solution
Answer:
Gradient of line A = 4
Gradient of line B = -2
Step-by-step explanation:
To solve this question, we will use the formula for gradient passing through two points 
and 
,
Gradient (m) = 
For line A,
Since, line A passes through (3, 6) and (4, 10)
Gradient of line A = 
= 4
For line B,
Since, line B passes through (1, 6) and (2, 4),
Gradient of line B = 
= -2
