It’s the third one.
144. 6 x 6 = 36
36 x 8 = 288
288 divided by 2 ( divide by half the dotted line)
answer : 144
Answer:
There is a 1/64 possibility.
Step-by-step explanation:
Since the probability of selecting student 1's number is 1/8 and then replacing it leaves us with still 8 numbers to choose from, so student 8's probability of being selected is also 1/8. Multiplying these two gives P=1/64, since (1/8)^2 = 1/64.
Hope this helps!
X x_ = (13+14+11+11+13+10)/6=12 x-x_ (x-x_)^2 standard deviation is
13 for all X_ it is the same 13-12=1 . 1. =(12/6)^1/2=1.41421
14 14-12=2 . 4.
11 11-12=-1 . 1.
11 11-12 =-1 . 1.
13 13-12=1 . 1.
10 10-12=-2. 4.
B. The answer is b because -2m and -5m together equal -7m-8, and on the other side of the equal sign 3+-7+m equal -4+m
