Answer:
Step-by-step explanation:
To solve this problem, we need to divide 3/10 gallons by 1 gallon, which is equal to 4 quarts.
First, let's convert the fraction 3/10 to a decimal by dividing the numerator by the denominator: 3 / 10 = 0.3
Then, we can divide 0.3 gallons by 1 gallon to get the equivalent number of gallons in quarts: 0.3 gallons / 1 gallon = 0.75 quarts
Since 1 quart is equal to 0.25 gallons, 0.75 quarts is equivalent to 3/4 of a gallon.
Finally, we can add the number of quarts given in the problem (11 quarts) to the number of quarts equivalent to the number of gallons (3/4 of a gallon, or 3 quarts). This gives us a total of 14 quarts, which is equivalent to 3 and 1/2 gallons.
Therefore, the final answer is 3 gallons and 11 quarts.

Answer:
To answer these questions, we need to first calculate the total number of payments you have made over the past 3 years. We can do this by multiplying the number of payments per year (12) by the number of years (3). This gives us a total of 36 payments.
Next, we can use a financial calculator or spreadsheet program to solve for the remaining balance on your loan after making 36 payments of $327.51 each. In a financial calculator, we can enter the following values:
N: 36
I: 5.8
PV: -14000
PMT: 327.51
FV: 0
Solving for PV gives us a remaining balance of $4,819.56. Therefore, the answer to part A is $4,819.56.
To find your equity in the car, we can subtract the remaining balance on the loan from the value of the car. In this case, your equity would be $7,500.00 - $4,819.56 = $2,680.44. Therefore, the answer to part B is $2,680.44.

If you choose a group of four tiles, what is the probability you get four tiles that are each worth one point? Write your answer as a decimal with three decimal places (0.XXX), not as a percent.
The probability to choose a group of four tiles with each tile worth one point is 0.200.
What is probability?
The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a proposition to be true. A number between 0 and 1 is the probability of an event, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.
Let there are total 25 tiles.
From this 20 tiles having one point each and 5 tiles having more than one point.
We have to choose a group of four tiles with each tile worth one point.
So,
probability = 4/20 = 0.200
Hence, the probability to choose a group of four tiles with each tile worth one point is 0.200.

What is coordinate?The horizontal and vertical distances from the two reference axes are used to define the location of a point on a coordinate plane. The x-value and y-value are often denoted as (x,y). To find the coordinates of a point in a coordinate system, do the inverse. Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate. Then repeat the process, but this time follow a horizontal line to determine the y-coordinate. The distance between two points is known as the x-coordinate, or abscissa, while the distance between two points is known as the y-coordinate, or ordinate.

The angle measures in this problem are given as follows:
7 - m < ADC = 82º.
8 - m < ADC = 44º.
How to obtain the angle measures?In item 7, the angle measure is found obtained the angle addition postulate, meaning that the measures are obtained as follows:
m<ADB = m < BDC + m < ADC.
Then the equation to find the value of x is obtained as follows:
144 = 7x + 34 + 9x + 46
16x = 64
x = 64/16
x = 4.
Then the angle ADC is obtained as follows:
m < ADC = 9(4) + 46 = 82º.
In item 8, the bisection means that the two angle measures are equal, hence the value of x is obtained as follows:
7x - 19 = 9x - 37
2x = 18
x = 18/2
x = 9.
m < ADC = 9(9) - 37 = 44º.

Jane is having difficulty deciding whether to put her savings in the Mystic Bank or in the Four Rivers Bank. Mystic offers a 12% rate compounded quarterly, and Four Rivers offers 14% compounded semiannually. Jane has $40,000 to invest and expects to withdraw the money at the end of five years. The better deal is:
Multiple Choice
Four Rivers because she will earn about $6,442 more.
Four Rivers because she will earn about $6,523 more.
Four Rivers because she will earn about $4,000 more.
Four Rivers because she will earn about $20,000 more.
Jane must therefore deposit her savings in the four rivers bank.
What is compound interest?Interest that is added to a loan and deposit sum is known as compound interest. In our everyday lives, it is the notion that is employed the most frequently. Compound interest is calculated as a sum using the interest and principal accrued over time. Compound interest versus simple interest differ primarily in this way.
As per the data provided in the question,
Rate, r = 12%
After five years, the total amount, if Jane had saved at Mystic Bank,if Jane had saved at Mystic Bank would be:
[tex]A = P(1+\frac{r}{100} )^n[/tex]
For compounded quarterly,
n = 5 × 4
n = 20
A = 40000(1 + 12/(4 × 100))²⁰
A = 72244.44 (i)
If Jane placed her savings with the Four Rivers, then,
A = 40000(1 + 14/(2 × 100))¹⁰
A = 40000 × 1.9671
A = 78686.054 (ii)
Therefore, it is evident that case (ii) is higher than case (i). Jane must therefore deposit her savings in the four rivers bank.

find the absolute maximum and absolute minimum values of f on the given interval. f(x) = xe−x2/32, [−2, 8]
The absolute maximum and absolute minimum values of f(x) are 2.426 and -1.765, respectively.
What is meant by absolute maximum and absolute minimum values?
A function's absolute maximum point is the point at which it can reach its highest value. A similar absolute minimum point is where the function's least possible value is obtained.
Given: [tex]f(x)=xe^{\frac{-x2}{32} }[/tex]
Differentiate the function,
[tex]f'(x)=e^{\frac{-x^{2} }{32} } -\frac{x^{2} }{16} e^{\frac{-x^{2} }{32} }[/tex]
[tex]e^{\frac{-x^{2} }{32} } -\frac{x^{2} }{16} e^{\frac{-x^{2} }{32} }=0[/tex]
[tex]\frac{x^{2} }{16} e^{\frac{-x^{2} }{32} }=e^{\frac{-x^{2} }{32} }[/tex]
[tex]\frac{x^{2} }{16} =1[/tex]
[tex]x^{2} =16[/tex]
[tex]x=[/tex] ±[tex]4[/tex]
The interval is given as: [-2,8]
This means that the value of x = -4, is out of the interval.
So, we have the following critical points:
x = (-2, 4, 8)
⇒ f(x) at x = -2
[tex]f(-2)=-2[/tex] × [tex]e^{\frac{-(-2)^{2} }{32} }[/tex]
[tex]f(-2)=-2[/tex] × [tex]e^{\frac{-4}{32} }[/tex]
[tex]f(-2)=-1.765[/tex]
⇒ f(x) at x = 4
[tex]f(4)=4[/tex] × [tex]e^{\frac{-(4)^{2} }{32} }[/tex]
[tex]f(4)=4[/tex] × [tex]e^{\frac{-16}{32} }[/tex]
[tex]f(4)=2.426[/tex]
⇒ f(x) at x = 8
[tex]f(8)=8[/tex] × [tex]e^{\frac{-(8)^{2} }{32} }[/tex]
[tex]f(8)=8[/tex] × [tex]e^{\frac{-64}{32} }[/tex]
[tex]f(8)=1.083[/tex]

A jar contains 5 red marbles numbered 1 to 5 and 6 blue marbles numbered 1 to 6. A marble is drawn at random from the jar. Find the probability that the marble is blue or even-numbered.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
The probability of drawing an even-numbered blue marble.
= Number of even blue marble / Total number of marbles
The probability of drawing an even-numbered blue marble is 3/11.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
Number of red marbles = 5
Number of blue marbles = 6
Number of even blue marbles = 3
Total number of marbles = 5 + 6 = 11
The probability of drawing an even-numbered blue marble.
= Number of even blue marble / Total number of marbles
= 3/11
Thus,
The probability of drawing an even-numbered blue marble is 3/11.

the given statement if a is an n x n diagonalizable matrix then each vector in R^n can be written as a linear combination of eigenvectors of a is false.
What is Diagonalizable matrix?
If there is an invertible matrix P and a diagonal matrix D such that
P^-1AP=D, or alternatively A=PDP^-1, then the square matrix A is said to be diagonalizable or non-defective in linear algebra.
If and only if the algebraic multiplicity of each of A's eigenvalues is equal to the geometric multiplicity of each eigenvalue, then A is diagonalizable. The fact that the geometric sum of the eigenvalues of A is n is an equivalent description.
The given statement is false.
If A is diagonalizable, then A had n distinct eigenvalues. It could have repeated eigenvalues as long as the basis of each eigenspace is equal to the multiplicity of that eigenvalue.
Hence, the given statement is false.
