Answer:
x = 4.5 or rounded 5
Step-by-step explanation:
Because they are equal you can make the equation:
x/2 = 18/8
this means that 8 divided by 2 equals (4)
what 18 divided by x is (4)
this means 4 times x = 18
4x = 18
/4 /4
x = 4.5 ft
The factors of 36 are 1 and 36, 2 and 18, 3 and 12, 4 and 9, 6 and 6. With those being the factors you can see that there are 9 different whole numbers.
Answer:
And we can find this probability using the z score table or excel:
So then we can conclude that the proportion of fish that are safe to eat is about 0.734
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 concentrations of mercury in individual fish 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 z score table or excel:
So then we can conclude that the proportion of fish that are safe to eat is about 0.734
So lets say u have 100$ and it decreases by 100% u would have no money left
Answer:
A = 213.52
Step-by-step explanation:
A = 4 pi radius square
diameter = 34
radius is half of diameter
radius = 17
A = 4(pi or 3.14)(17)
A= 213. 628300444 with pi
A = 213.52 with 3.14
hopefully this helps you understand this concept
