Answer:
B. 37
Step-by-step explanation:
You first find the median of the entire set which is 46. Then find the median of the lower half of the set which is 27. Then find the median of higher part of the data set which is 64. Then you do 64-27=37.
Hope that helped a little bit :)
Answer:
0.5532
Step-by-step explanation:
P( 31<X<35.7)
P(X>31)= P(Z>(31-μ)/σ)
= P(Z>(31-34.6)/2.8)
= P(Z> -1.2857)
P(X<35.7)= P(Z<(35.7-μ)/σ)
= P(Z<(35.7-34.6)/2.8)
=P(Z< 0.392857)
From z-distribution table
P(Z< -1.29)= 0.09853
p(Z< 0.39) = 0.65173
P( 31<X<35.7)= P(Z<0.39)- P(Z<-1.29)
= 0.65173- 0.09853
=0.5532
Answer:
12
Step-by-step explanation:
a2 +b2 = c2
a2 + 9 2 = 15 2
a2 + 81 = 225
- 81 - 81
a2 = 144
a = 12
