Answer: D: 242m³
Step-by-step explanation:
Well, 9x5=45 and if you calculate that in cubic meters i believe it would be 243m³ (I'm in 7th grade...=/) HAPPY EARLY VALENTINES DAY! HOPE YOU GET THIS RIGHT! =D

Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Part a
Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:
Where
and
We are interested on this probability
And the best way to solve this problem is using the normal standard distribution and the z score given by:
If we apply this formula to our probability we got this:
And we can find this probability like this:
And in order to find these probabilities we can find tables for the normal standard distribution, excel or a calculator.
Part b
For this case we select a sample size of n =32. Since the distribution for X is normal then the distribution for the sample mean
is given by:
And the new z score would be:



Answer:
30
Step-by-step explanation:
because if x is 5 then 6(5)
and 6x5=30
The multiplier of each account's value is 1.05³ = 1.157625.
The $750 in the club's account will grow to
$750×1.157625 = 868.22
and each member will get 1/3 of that amount, $289.
The $250 in Sheri's individual account will grow to
$250×1.157625 = $289.
Sheri, Kayla, and Kayla's two friends will all have the same amount as a result of their investments.
