Answer:
My guess is 2b^5
Step-by-step explanation:
This question is kinda tricky. LMK if its correct
P(400<x<450)
P( (400-400)/50 < Z< (450-400)/50)
P (0 <z< 1) = 0.8413 -0.500=0.3413 = 34.13%
Answer:
46
Step-by-step explanation:
So, we have these values:
40: 1 time
41: 2 times
45: 1 time
48: 2 times
49: 3 times
50: 1 time
A total of 10 dots spread over 6 values.
We need to calculate a weighted mean (average) for them... so, we add up each dot then divide the total by 10:
40 + 41 + 41 + 45 + 48 + 48 + 49 + 49 + 49 + 50 = 460
460 / 10 = 46
The answer should be 18 because 10/1 1/4=0.125+1 1/4=1.375+0.125=1.5x12=18
this should be correct i’m truly sorry if it’s not
