The total expenses in the month, for Frank and Yvette Shelby can be found to be $ 1, 288. 96 .
The housing costs are within the 35 % guideline of their combined income.
How to find the expenses ?The total expenses to Frank and Yvette Shelby for the month would be:
= Mortgage Payment + Insurance-Liability and Contents + Home Equity Loan + Electricity + Heating (gas) + Internet & Phone Bundle + Water & Sewer + Satellite TV Service
= 533. 50 + 35. 55 + 132. 40 + 158. 66 + 243. 80 + 68. 75 + 65. 30 + 51. 00
= $ 1, 288. 96
The percentage of housing cost to the total income of Frank and Yvette Shelby is:
= ( Mortgage Payment + Insurance + Home Equity ) / combined income x 100 %
= ( 533. 50 + 132. 40 + 35. 55 ) / ( 1, 860 + 1, 900 ) x 100 %
= 18. 66 %
The housing costs are therefore within the 35 % guideline of their combined income.

1. What percent of songs were played over 100 times?

2. What is the mean?
songs (round to the nearest whole integer)
3. What percent of songs were played less than 20 times?

played from the information in the histogram.
Correct responses (rounded to the nearest whole integer)

3. 68%
How does one analyze an histogram?1. The given data from the histogram is presented in a tabular form as follows;

The percentages of song that where played over 100 times is given as follows;
∑f = 899+224+126+96+71+52+39+41+44+23+14+12+3+4+3 = 1651
Number of songs played over 100 times = 14 + 12 + 3 + 4 + 3 = 36
\(Percentage \ of \ songs \ played \ over \ 100 \ times = \mathbf{\dfrac{36}{1,651} \times 100} \approx \underline{2 \%}\)2. Mean of a frequency distribution is given as follows;
\(Mean = \mathbf{\dfrac{\sum f\times x}{\sum f}}\)
Where;
x = The PlayCount
From MS Excel, we have;
∑f·x = 44410
Which gives;
\(Mean = \dfrac{44410}{1651} \approx \underline{27}\)3. Number of songs played less than 20 times = 899 + 224 = 1,123

Answers
Based on the information, there are 25 cars with good brakes and good tires.
How to calculate the valueTotal cars = 50
Cars with faulty brakes = 10
Cars with faulty tires = 15
Cars with faulty brakes and good tires = 2
Let's calculate the number of cars with good brakes and good tires:
Cars with faulty brakes or faulty tires = Cars with faulty brakes + Cars with faulty tires - Cars with faulty brakes and good tires
= 10 + 15 - 2
= 25
Cars with good brakes and good tires = Total cars - Cars with faulty brakes or faulty tires
= 50 - 25
= 25
Therefore, there are 25 cars with good brakes and good tires.

Answers
The dimensions of the rectangular box with largest volume if the total surface area is given as 100 cm2: x = y = z = 2.449 cm.
Given that:
Total surface area of the rectangular box or cuboid = 100 cm²
A rectangular box with largest volume is a cube.
The total surface area of a cube = 6 times square of one edge length.
Let the edge length = given dimensions; x, y, z
So,
x = y = z
6x^2 = 100
x^2 = 100 / 6
x = √ 100 / 6
x = 10 / √ 6 cm
x = 2.449 cm
Hence, dimensions of the rectangular box with largest volume if the total surface area is given as 100 cm2: x = y = z = 2.449 cm.

Answers
The radius of the semicircle having an arc of length equal to 8.5 \(\pi\) in a right-angle triangle ABC is equal to 7.5 cm.
Given:
Angle ABC of triangle ABC is a right angle. The sides of ABC are the diameters of semicircles.
The area of the semicircle on AB equals 8\(\pi\).
Area of a semicircle = \(\pi r^2/2\)
Therefore:
\(\pi r^2/2\) = 8\(\pi\)
\(r^2 = 16\)
\(r = 4\)
Next, the arc of the semicircle on AC has a length of 8.5\(\pi\).
Length of the arc of a semicircle = \(\pi r\)
\(\pi r\) = 8.5\(\pi\)
\(r = 8.5\)
Using Pythagoras theorem
\(8.5^{2} = 4^{2} + x^{2}\)
\(x^{2} = 8.5^2 - 4^2\\\)
\(x^{2} = 56.25\)
\(x = \sqrt{56.25}\)
\(x = 7.5\)
The radius of the semicircle of BC = 7.5 Units.

If values prοvided then transfοrmatiοn οf vectοrs can be determined.
What is vectοr?In mathematics, a vectοr is a mathematical οbject that represents a quantity with bοth a magnitude and a directiοn. Vectοrs can be used tο represent physical quantities such as velοcity, fοrce, and acceleratiοn, as well as mοre abstract cοncepts such as cοlοr, sοund, and temperature.
Withοut seeing the figure οr the values οf a1, a2, and a3, it is nοt pοssible tο determine whether the specified linear transfοrmatiοn T : R2 → R2 is οne-tο-οne and οntο.
Hοwever, in general:
A linear transfοrmatiοn T : Rn → Rm is οne-tο-οne if and οnly if its kernel (i.e., the set οf vectοrs that are mapped tο the zerο vectοr) is trivial, meaning that the οnly vectοr that maps tο the zerο vectοr is the zerο vectοr itself.
A linear transfοrmatiοn T : Rn → Rm is οntο if and οnly if its range (i.e., the set οf all vectοrs that can be οbtained by applying T tο sοme vectοr in Rn) is equal tο Rm.
Tο determine whether a linear transfοrmatiοn is οne-tο-οne οr οntο, we can examine its prοperties and characteristics, such as its kernel, range, rank, and determinant. We can alsο use geοmetric intuitiοn and visualizatiοn tο understand hοw the transfοrmatiοn maps pοints and vectοrs in Rn tο Rm.
If yοu prοvide mοre infοrmatiοn abοut the values οf a1, a2, and a3 and the figure that shοws the standard matrix A, it can help yοu determine whether the transfοrmatiοn is οne-tο-οne and οntο and draw the image οf the vectοr [-1, 1] under the transfοrmatiοn T.
