3.59
Step-by-step explanation:
Answer:
1,000
Step-by-step explanation:
20
20×10×5=1,000
This function represents exponential decay.
We know it's exponential because the value the base (200) is being multiplied by is being raised to the power of x.
In this case, the multiplication value is 0.8, which is less than 1.
If the multiplication value is less than 1, than the function will decay, rather than grow.
In this case, the factor is 0.8, or 80%.
Answer:
And we can find this probability using the normal standard table or excel:
Step-by-step explanation:
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".
Solution to the problem
Let X the random variable that represent the amount of ml 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 using the normal standard table or excel:
Answer:
P= 22x+10 7x+9x+6x+8+6-4 = 22x+10
when x=10, 22(10)+10=230mm
