Answer:
Step-by-step explanation:
The midpoint formula is useful here. For midpoint M, we have ...
M = (C + D)/2
2M = C + D
2(10, 10) = (15, s) +(t, 3)
(20, 20) = (15+t, s+3)
t = 20 -15 = 5
s = 20 -3 = 17
__
<em>Check</em>
(C +D)/2 = ((15, 17) +(5, 3))/2 = (20, 20)/2 = (10, 10) . . . checks OK
Step-by-step explanation:
this is an arithmetic sequence :
a1 = 1
an = an-1 + 2 = a1 + (n-1)×2
the sum of n terms of an arithmetic sequence is
S = n×(a1 + an)/2
n = 5000
an = a1 + 4999×2 = 9999
S = 5000×(1 + 9999)/2 = 5000×5000 = 25,000,000
Answer:
B, A, C
Step-by-step explanation:
Calculating the common ratio for each sequence
A → r = = = 0.25
B → r = = - 3
C → r = = 1.5
B, A, C ← from least to greatest common ratio
Answer:
See below.
Step-by-step explanation:
Positive association is when the line has a positive slope, and the line progresses upwards.
E.g. When a car is traveling, as time progresses, the distance traveled increases.
Negative association is when the line has a negative slope, and the line declines.
E.g. When a car is traveling, as time progresses, the amount of gasoline decreases.
No association is when there is no slope between points, nor is there a line.
