Answer:
This is false.
Step-by-step explanation:
Hope this helps!!
Y = t*e^(-t/2)
y' = t' [e^(-t/2)] + t [e^(-t/2)]' = e^(-t/2) + t[e^(-t/2)][-1/2]=
y' = [e^(-t/2)] [1 - t/2] = (1/2)[e^(-t/2)] [2 - t] = - (1/2) [e^-t/2)] [t -2]
Answer:
- 16
Step-by-step explanation:
This is very tricky. Be careful how you do it.
The total of the six numbers is 6*41 = 246
The total of five numbers = 5*46 = 230
What have you you removed to make the number average go up with a smaller sample? The answer is a negative.
230 - 246 = - 16
There are 23 such numbers. Here they are:
10
14
18
22
26
30
34
38
42
46
50
54
58
62
66
70
74
78
82
86
90
94
98
This is the answer. I did it and got that. You do distributive and then combine like terms.
