Itd be $4.78
1200/251.2=4.77707006, rounded to the nearest cent would be $4.78 :)
Answer:
Both functions have one x-intercept each.
Step-by-step explanation:
The first function is

This is a parabola with vertices at the origin and has one x-intercept at t=0.
The transformed function is

The function g(t) is obtained by shifting the graph of f(t) to the left by 3 units.
This graph also has one x-intercept at x=-3.
Therefore both functions has the same number of x-intercepts
The probability of getting a <em>country CD</em> out of all the CDs is the number of <em>country CDs</em> divided by the <em>total number of CDs</em> in Dante's Collection.
The <em>total number of CDs</em> in Dante's collection is
.
The total number of <em>country CDs</em> is 12.
So our required probability is
.
In percentage this is 3 divided by 10, and then multiply by 100. We get 30%. Answer choice D is correct.
ANSWER: D
Using the geometric mean concept, it is found that the value of a is 18.
----------------------
The geometric mean, of a data-set of n elements,
, is given by:
![G = \sqrt[n]{n_1 \times n_2 \times ... \times n_n}](https://tex.z-dn.net/?f=G%20%3D%20%5Csqrt%5Bn%5D%7Bn_1%20%5Ctimes%20n_2%20%5Ctimes%20...%20%5Ctimes%20n_n%7D)
That is, the nth root of the multiplication of all elements.
----------------------
In this question:
- Two elements(n = 2), a and 34.

Thus:

We find the square of each side, so:


Simplifying both sides by 17:



The value of a is 18.

Step-by-step explanation: To estimate the value of the square root of 59, we know that the square root of 49 is 7 and the square root of 64 is 8. This means that the square root of 59 must have a value between 7 and 8.
