A 3x + 2
Step-by-step explanation:
3x+2 is a polynomial.
If the variable in a term of polynomial is multiplied by a number, then this number is called the "coefficient"
It contains a first degree term as highest degree term and one constant term.
coefficient=3
constant=2
variable=x(first degree term)
Given that the decay rate of the uranium is given to be 57%, this means that on the second day only 43% of the Uranium-233 will be left. The equation therefore, that will allow us to answer the question is that,
A(t) = A(0)(1 - r)^n
where A(t) is the amount after n days, A(0) is the original amount, r is the decimal equivalent of the rate and n is the number of days. Substituting the known values,
A(t) = (3,820 pounds)*(1-0.57)^15
A(t) = 0.0121 pounds
This is unfortunately not found in the choices.
Answer/Step-by-step explanation:
The ratio of the enlargement to the original = A'E' to AE = A'E':AE = A'E'/AE
AE = 2.5
A'E' = 4
Ratio of the enlargement to the original = 4:2.5 = 1.6:1
To convert to percentage, divide 4 by 2.5 and multiply by 100.
To solve this problem, let us first define what is mean
and median. Mean is the average of all the numbers in the data set while
the median is the number in the middle of the data set in ascending order.
If we create a box plot for the data of Rome and New York,
we can see that there is an outlier in the data for New York. Since New York
has an outlier, so the mean is not a good representation on the central
tendency of the data. The mean is skewed (distorted) by the outlier. So in this
case it is better to use the median.<span>
While the Rome data is nice and symmetrical, it does not seem
to have an outlier, so we can use the mean for this data set.</span>
Therefore the answer is:
<span>The Rome data center is best described by the mean. The
New York data center is best described by the median</span>
