To answer this you need to find the probability that it is 18 first. The only way to get 18 is by rolling 3 6's. The probability of each 6 is 1/6. 1/6 * 1/6 * 1/6= 0.0046. That is the probability of rolling 3 die and getting 18. To get the actual answer, you just subtract that from 1
1-0.0046 equals 0.9954
Answer: 
Step-by-step explanation:
For it to bisect the segment, we need to find the midpoint.
The midpoint is 
Now, for it to be perpendicular, we need to use the fact that perpendicular lines have slopes that are negative reciprocals of each other.
The slope of the given segment is 
, so the slope of the perpendicular bisector is 
Thus, the equation of the line in point-slope form is 
You change 1/3 and 3/4 so that they have the same denominator.
The GCF is 12 in this case.
1/3 x 4 = 4/12
3/4 x 3 = 9/12
4/12 + 9/12 = 13/12 or 1 1/12 (One and one twelfth)

21. 41642 people moved. Of those people, 26% moved for family related reasons. So 26% of 41642 = 0.26(41642) = 10826.92......so about 11,000 moved for family related reasons.
22. that would be 6% which = 0.06 which equals 6/100
23. 41672 moved. 50% moved for housing related reasons.
50% of 41642 = 0.50(41642) = 20821.....about 21000
Answer: 0.55
Step-by-step explanation:
Given :
A typical adult has an average IQ score of n 
with a standard deviation 
.
Sample size : n= 20
Let x represents the IQ score of adults.
The probability that the sample mean scores will between 102 and 110 points will be :-
Therefore, the probability that the sample mean scores will between 102 and 110 points = 0.55
