Answer:
10.55% probability
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the CDs are chosen is not important. So we use the combinations formula to solve this question.
1 Bach CD, from a set of 4.
1 Beethoven CD, from a set of 6.
1 Brahms CD, from a set of 3.
1 Handel CD, from a set of 2.
So, D=144
4 CDs from a set of 4+6+3+2 = 15.
So, T= 1365
p= D/T= 144/1365 = 0.1055
10.55% probability that she will choose one by each composer
Answer:
52 degrees
Step-by-step explanation:
Every triangles angles sum up to 180 degrees
83+45=128
180-128=52 degrees
Answer:
Option D. No solutions
Step-by-step explanation:
we have
-----> equation A
----> equation B
Multiply by -3 both sides equation A

-----> equation C
Compare equation B and equation C
Equation B and equation C are parallel lines with different y-intercept
<u><em>Verify</em></u>
For x=0
<em>Equation C</em>
----->
The y-intercept is the point (0,0.5)
Equation B
----->
The y-intercept is the point (0,-0.5)
therefore
Lines do not intersect
The system has no solution

Answer:
The "total loan cost" formula is what you'll need (and it is attached).
Interest =1.25 / 1,200 = 0.0010416667
and "n" is number of months (6 years = 72 months)
Total Loan Cost = (r*p*n) / 1 -((1 + r)^-n)
Total Loan Cost = (0.0010416667 * 12,000 * 72) / 1 -((1.0010416667)^-72)
Total Loan Cost = 900 / 1 -0.9277797019
Total Loan Cost = 900 / 0.0722202981
Total Loan Cost = 12,461.87
Step-by-step explanation:
The lengths of one house is not proportional to the lengths of the other house because the structure of the houses are not the same.
<h3>How to depict the information?</h3>
The scale factors can be used to show that the homes are or are not proportional. This can show that the first house doesn't have chimney and rtw second one has.
The role of the surface area take in the building of a house is that it tells us about the sum of its total area covered by the four walls.
The advantage that exist for a house with a large amount of surface area is that it gives more stability.
