Answer:
The probability mass function of random variable X which represents the number of blue marbles drawn in 2 draws with replacement.
X | P(X)
0 | 0.390625
1 | 0.46875
2 | 0.140625
The probability of drawing exactly one blue marble = 0.46875
0.46875 as a simplified fraction is ------ 15/32
Step-by-step explanation:
Answer:
3/1 ; 0/3 ; -191/32 ; 3/456
Step-by-step explanation:
We have to find all the numbers that are expressed with a fraction:
1) is a trap because the division is impossibile
2) true: 3/1 is a fraction
3) true: 0/3 is a possible division and it results 0
4) true: is a fraction
5) true: is a fraction
D, Store 1. $26.62/38 = 0.74
Store 2. $22.42/28 = 0.80
Answer:
1. 252N = ( x x )N
2. Factor =
Step-by-step explanation:
Let the starting population size for organisms A and B be represented by N.
For organism A;
Day 0: N
Day 1: 2N
Day 2: N
Day 3: N
Day 4: N
Day 5: N
Day 6: N
Day 7: N
Day 8: N
For organism B;
Day 0: N
Day 1: 2N
Day 2: N
Day 3: N
Day 4: N
Day 5: N
Day 6: N
Day 7: N
Day 8: N
1. After the eight days, organism B's population is larger than organism A's population by;
N - N = 256N - 4N
= 252N
= ( x x )N
2. Organism A's population grows by .
