Answer:
0.3991
Step-by-step explanation:
Given that the weights of the fish in a certain lake are normally distributed with a mean of 18 lb and a standard deviation of 18 .
we know that when a sample is taken mean would be the same but std error would vary
when a sample of size 15 is taken we have
Standard error of sample =
the probability that the mean weight will be between 16.6 and 21.6 lb
So we get the required probability as
0.3991
Answer:
the answer is that
Step-by-step explanation:
because i know
To solve this you will need to take 90-15=75 then take 75/3=25 so a biscuit costs 25p and a cake costs 40p becuase 25*2=50+40=90 enjoy!=)
Answer:
27
Step-by-step explanation:
Let T be the capacity of the tank.
Since the tank was 1/3 full and ends up 7/9 full.
T - T = 12
Simplifying the left side of the equation, tells us how much 12 gallons fills.
T = 12
Now we solve for T:
T = 12*9/4
T = 27
