Answer:
a) 1/2 (50%)
b) 1/2 (50%)
c) 3/4 (75%)
d) 3/4 (75%)
Step-by-step explanation:
for a uniform distribution
P(X=x)= x-A/(B-A) , for A≤x≤B
then
P(X=x)= (x+8)/16 , for -8≤x≤8
a) P(X<0)= interval chosen / total interval = (0-(-8))/(8-(-8)) = 1/2 (50%)
b) P(-4<X<4)= interval chosen / total interval =(4-(-4))/(8-(-8)) = 1/2 (50%)
c) P(-5<X<7)= interval chosen / total interval =(7-(-5))/(8-(-8)) = 3/4 (75%)
d) for −8 < k and k + 4 < 8 → k < 4 , then -8<k<4 , thus k
P(X=k)= P(-8<X<4) = interval chosen / total interval =(4-(-8))/(8-(-8)) = 3/4 (75%)
Answer:
We found the factors and prime factorization of 32 and 48. The biggest common factor number is the GCF number. So the greatest common factor 32 and 48 is 16.
Step-by-step explanation:
What is the GCF of 32and 48?
16
Greatest common factor (GCF) of 32 and 48 is 16.
150/120 (girls to boys)
150/270 (girls to students)
those would be your ratios...hope you find it helpful :)
Im sorry but ion really understand it but i think its killometers
