Answer:
In 300 draws Ellen should expect to draw a blue marble 120 times.
Step-by-step explanation:
Number of red marbles = 3
Number of blue marbles = 2
Total number of marbles = ![3+2=5](https://tex.z-dn.net/?f=3%2B2%3D5)
Probability of drawing blue marbles = ![\frac{numberof possible outcomes}{total number of outcomes}](https://tex.z-dn.net/?f=%5Cfrac%7Bnumberof%20possible%20outcomes%7D%7Btotal%20number%20of%20outcomes%7D)
=>
= 0.4
Total number of draws = 300
So, in 300 draws Ellen should expect to draw a blue marble:
times.
And in case if red is needed, it becomes:
times.
B.
I think B will make more B make more sense because you say he gets 75 a week.
F(x)=2^x
Lets say f(x) is y
Y=2^x
Take log both side
Log(y)=log(2^x)
Logy=log2^256
logy=256×log2
By Log property
Logy=77.06

Answer:
You can use a ratio to solve this problem. Use x as a variable for the cups of food in 28 days.
1 (day): 3 (cups)
28 (days): x (cups)
Cross multiply.
x=28(3)
x=84
So, Li’s dog eats 84 cups of food in 28 days.
