Answer:
0.9544 or 95.44%
Step-by-step explanation:
The empirical rule indicates that the percentage of data falls in one standard deviation, 2 standard deviation and 3 standard deviation are 68.26%,95.44% and 99.73%
We are given that x1=52, x2=76 ,mean=64 and standard deviation=6
mean+sd= 64+6=70
mean-sd=64-6=58
mean+2*sd=64+12=76
mean+2*sd=52
x1 and x2 are within 2 standard deviation and the percentage of data lies between two standard deviation is 95.44%.
Answer:
You are right, it's B

Answer:
None
Step-by-step explanation:
It would be easier to ask your teacher instead of getting wrong answers from random people. Ever think of that :0
Perform indicated multiplications on left side.
8-40x=13 subtract 8 from both sides
-40x=5 divide both sides by -40
x=-5/40
x=-1/8
Note: There are no mixed numbers in this problem.
Same and don’t worrie all you need to know is that if you are getting stuck on a problem yell at your teacher and throw stuff at people
