Answer:
X= 2.5 Y= 3.5
Step-by-step explanation:
2X+3Y =15.5
replace either x or y with your second equation
(2*(6-y))+3y=15.5
now you only have one variable
12-2y+3y=15.5
y=3.5
now insert your y value into the second equation provided
x+y=6
x+3.5=6
so x= 2.5
you can check your answer by inserting these numbers into the equations and it should work
Amount financed
137,900−137,900×0.20
=110,320
number of thousands
110,320÷1,000
=110.32
Multiply it by the monthly payment per thousands
110.32×7.34
=809.7488
Now multiply it by the number of months in a year
809.7488×12 months
=9,716.9856
Multiply it by the number of years
9,716.9856×30
=291,509.568
Now the total amount of interest charged
291,509.568−110,320
=181,189.568 round your answer
=181190...answer

Answer: a) 0.0058
b) 0.0026
Step-by-step explanation:
Given : The probability of having clear sunny skies in Seattle in July : p= 0.40
The number of days spent in Seattle in July: n= 18
a) Using, Binomial probability formula :
The probability of having clear sunny skies on at least 13 of those days:-
b) On converting binomial to normal distribution, we have
Let x be the number of days having clear sunny skies in Seattle in July.
Then, using we have
P-value =
Using function concepts, we have that:
- The independent quantity is the time.
- The dependent quantity is the volume.
- Graph H fits this problem.
<h3>What is the relation between a function and the dependent and independent variables?</h3>
A function has the following format: y = f(x).
In which each value of <u>y is a function of one value of x</u>, and thus, x is the independent variable and y is the dependent variable.
That is, the input of the function is the independent variable and the output is the dependent variable.
For this problem, the <u>volume is a function of time</u>, hence Volume = f(Time) and:
- The independent quantity is the time.
- The dependent quantity is the volume.
The <u>decay rate is constant</u>, meaning that we have a <u>decreasing linear function</u>, and graph H fits this problem.
