Answer:
Step-by-step explanation:
Sampling with replacement means that we choose a marble, note its colour, put it back and shake the box, then choose a marble again.
There are 
marbles in total. The probability that the first chosen marble is blue is 
then Maya replaces this marble and the probability of choosing the second blue marble is the same. Using the product rule, the probability of drawing 2 blue marbles in a row is
Answer:
40
Step-by-step explanation:
look at the picure for step by step explanation
First we multiply the numbers ignoring the decimal and then place the decimal in the position
3.04 *7.091 = 2155664
Now the first number has two digits after the decimal and the second number has three digits after the decimal.
Therefore in the final result we have to move the decimal (2+3) =5 place from the left,
So the answer would be 21.55664
So, the correct answer is 21.55664
Jerry calculated the answer correctly , but made an error in the placement of the decimal point. The answer is not reasonable because 2.155664 and 21.55664 mean two completely different answer far apart from each other
we are given that
3 chickens to lay 32 eggs
now, we can find number of eggs per chicken
number of eggs per chicken= (total eggs)/(total chicken)
so, we get
number of eggs per chicken is
now, we can set up following
1.5 chicken : 1.5 eggs : 1.5 days
3 chickens : 3 eggs : 1.5 days
1 chicken : 1 egg : 1.5 days
Since, changing number of chicken won't affect time
time to lay eggs will always remain same
so,
for 1 chicken to lay eggs
it takes
..............Answer
x/110 = (320-x)/90
<span> Cross multiply</span>
90x = 35200-110x
200x=35200
X = 35200/200 = 176 (distance traveled by train going 110 mph
176/110 = 1.6 hours = 1 hour and 36 minutes
Check: 110*1.6 = 176, 90*1.6 = 144
176+144 = 320
it will take 1.6 hours ( 1 hour 36 minutes) for the trains to meet
