Proportionately, the dollar amount of the Gentrys' annual transportation and taxes combined is $11,004.70.
What is proportion?Proportion refers to the relative value of a number compared to another amount.
Proportions are ratios equated to one another.
Multiplying the proportional percentage of the combined transportation and taxes to the total budget of the Gentrys gives the dollar amount.
Yearly income for the Gentrys = $29,742.42
Percentage of income that is taxes = 28%
Percentage of income that is transportation = 9%
Combined percentage of taxes and transportation = 37% (28 + 9)
Combined transportation and taxes in dollars = $11,004.70 ($29,742.42 x 37%)
Thus, based on their proportional percentages, the Gentrys' combined annual transportation and taxes are $11,004.70.

What is angle?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles.
Given:
The measure of ∠ MLE = 1 / 2 m, ∠ ELB = 2 (m + 5)
Calculate the value of m as shown below,
∠ MLE + ∠ ELB = 90 (As given on figure)
1 / 2 m + 2 (m + 5) = 90
1 / 2 m + 2 m + 10 = 90
m + 4 m + 20 = 180
5 m = 180 - 20
m = 160 / 5
m = 32
Hence, ∠ MLE = 32 / 2 = 16°, and ∠ ELB = 2 (32 + 5) = 74°

The value of angle x in the straight line is 41 degrees.
How to find the angle x?The sum of angles on a straight line is 180 degrees. In other words, angles on a straight line add up to 180°. Angles on a straight line relate to the sum of angles that can be arranged together so that they form a straight line.
Therefore, let's find the angles x.
Using sum of angles on a straight line,

Jimmy is going to the store to buy candles. Small candles cost $3.50, and large candles cost $5.00. He needs to buy at least 20 candles, and he cannot spend more than $80. Let x represent the number of small candles and y represent the number of large candles.
The inequalities that can be used to represent the situation are:
3.50x + 5y ≤ $80x + y ≥ 20.What are inequalities?Inequalities are mathematical statements showing that two or more mathematical expressions are unequal.
With inequalities, two or more values are compared to show that they are not equivalent.
Inequalities can be represented as follows:
≤: "less than or equal to"<: "less than"≠: "not equal to">: "greater than"≥: "greater than or equal to."The cost of small candles per unit = $3.50
The cost of large candles per unit = $5.00
The number of small candles = x
The number of large candles = y
The number of candles Jimmy needs to buy ≥ 20
The total amount Jimmy can spend on the candles ≤ $80
Inequalities:3.50x + 5y ≤ $80

The amount paid for the truck for 300 miles is $333
How to determine the amount paid for the truckFrom the question, we have the following parameters that can be used in our computation:
Amount paid per day = $33
Amount paid per mile = $1
Number of miles driven = 300
The amount paid for the truck is then calculated as
Amount paid for the truck = Amount paid per day + Amount paid per mile x Number of miles driven
Substitute the known values in the above equation, so, we have the following representation
Amount paid for the truck = 33 + 300 * 1
Evaluate the products
Amount paid for the truck = 33 + 300

A. Describe the sampling distribution of for a random sample of size 25.
The distribution of x is normal with mean 2 mm and standard deviation (Need to find standard Deviation) mm.
B.
When no unusual circumstances are present, we expect x to be within 3 x of 2 mm, the desired value. An x value farther from 2 mm than 3 x is interpreted as an indication of a problem that needs attention. Calculate 2 ± 3 x.

Referring to part (b), what is the probability that a sample mean will be outside

A. The distribution of x is normal with mean 2 mm and standard deviation 0.008 mm.
B. The bounds are given as follows:
Lower bound: 1.976 mm.Upper bound: 2.024 mm.C. The probability that the sample mean is outside the interval 2 ± 3 x is given as follows: 0.003 = 0.3%.
How to obtain the probability using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].The mean and the standard deviation for the population are given as follows:
[tex]\mu = 2, \sigma = 0.04[/tex]
Hence, for a sample of 25, the standard error is given as follows:
s = 0.04 / square root(25) = 0.008 mm.
The interval for item b is within three standard errors of the mean, hence:
2 − 3 x = 2 - 3 x 0.008 mm = 1.976 mm.2 + 3 x = 2 + 3 x 0.008 mm = 2.024 mm.The Empirical Rule states that 99.7% of the measures are within three standard errors of the mean, hence the probability that the sample mean is outside the interval 2 ± 3 x is given as follows: 0.003 = 0.3%.

In rhombus ABCD, points E,F,G and H are the midpoints of AB, BC, CD and DA respectively. Quadrilateral EFGH has area 14 and perimeter 16. Find the side length for rhombus ABCD.
The side length of rhombus ABCD by using the formula for the perimeter of a quadrilateral is 4.
A rhombus is a quadrilateral with four equal-length sides in plane Euclidean geometry. The term equilateral quadrilateral refers to the fact that all of its sides are the same length.
Since EFGH is a quadrilateral with an area 14 and a perimeter 16, the sides of EFGH must all be of equal length. Since EFGH is composed of the midpoints of the sides of ABCD, the side length of ABCD must be twice the side length of EFGH.
Using the formula for the perimeter of a quadrilateral, 16 = 4x, so 4 = x. This means that the side length of ABCD is 4.
