The wholesale cost of a dining room table at a furniture store is $1,115.80. The
markup for the table is 20%. What is the selling price of the dining room table?
Answers
Answer: $1338.96
Step-by-step explanation:
The wholesale cost means the cost that the store buys the table from the supplier. To find the price that the store sells it, it is a 20% markup.
The orginal price is $1,115.80. What is 20% of $1,115.80?
$1,115.80 * .20 = $223.16
Lets add the original price to the markup.
$1,115.80 + $223.16 = $1338.96

D. It is a straight line.
Answers
The following are the characteristics of the graph of the linear parent function:
B. It has a slope of 1.
C. It is a parabola.
D. It is a straight line.
Lets explain the meaning of linear parent function
- A linear parent function is the equation y = x or f(x) = x
- A parent function is the simplest equation of a function
- It represented by a straight line passing through the origin point O
- The x-coordinate and the y-coordinate of any points lie on it are equal
- The slope of the line is 1 because the slope is the change of Δy/Δx
and Δy = Δx
The characteristics of the graph of the linear parent function are
∵ Linear parent function is f(x) = x and f(x) = y
∴ x = y
∵ The slope = Δy/Δx
∵ Δx = Δy because x = y
∴ The slope of it is 1
B. It has a slope of 1
∵ y = 0
∵ If x = 0 then y must = 0
∴ It goes through the origin
C. It goes through the origin
∵ It is a linear function
∵ All linear function represented by a straight line
∴ The graph of the linear parent function is a straight line
D. It is a straight line
Hence we get the right answers.

William opened two investment accounts. The first year, these investments, which totaled $2600, yielded $175 in simple interest. Part of the money was invested at 7.5% and the rest at 5%. How much was invested at each rate?
Answers
An amount of $1800 was invested at a rate of 7.5% and $800 was invested at a rate of 5%.
What is the percentage?The percentage is a ratio that can be expressed as a fraction of 100.
Given that, one part of $2600 was invested at a rate of 7.5% and the other part was invested at a rate of 5%, and the total yield was $175 simple interest.
Let $x was invested at 7.5%, then $(2600-x) was invested at 5%.
Since the yield is $175, it follows,
7.5% of x + 5% of (2600-x) = 175
7.5x/100 + 5(2600-x)/100 = 175
7.5x + 13000 - 5x = 17500
2.5x = 17500-13000
2.5x = 4500
x = 1800
Now, the value of (2600-x) is,
2600-1800
=800
Hence, $1800 was invested at a rate of 7.5% and $800 was invested at a rate of 5%.

William invested $1800 at 7.5% and $800 at 5% on his both accounts.
What is simple interest?We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, William opened two investment accounts. In the first year, these investments, which totaled $2600,
Assuming he invested $x at 7.5% on the first account and $(2600 - x) at 5% in the second account and yielded $175 in simple interest.
∴ (x×7.5×1)/100 + {(2600 - x)×5×1}/100 = 175.
7.5x/100 + (13000 - 5x)/100 = 175.
7.5x + 13000 - 5x = 17500.
2.5x = 4500.
x = 1800. And (2600 - x) = (2600 - 1800) = 800.

According to a study done by UCB students, the height for Martian adult males is normally distributed with an average of 65 inches and a standard deviation of 2.4 inches. Suppose one Martian adult male is randomly chosen. Let X = height of the individual. Round all answers to 4 decimal places where possible.
Answers
The probability that the person is between 67.1 and 68.3 inches, using the normal distribution, is of:
0.1056 = 10.56%.
Normal Probability DistributionThe 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.The mean and the standard deviation for the heights of UCB students are given as follows:
[tex]\mu = 65, \sigma = 2.4[/tex]
The probability that the person is between 67.1 and 68.3 inches is the p-value of Z when X = 68.3 subtracted by the p-value of Z when X = 67.1, hence:
X = 68.3:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (68.3 - 65)/2.4
Z = 1.38.
Z = 1.38 has a p-value of 0.9162.
X = 67.1:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (67.1 - 65)/2.4
Z = 0.88.
Z = 0.88 has a p-value of 0.8106.
0.9162 - 0.8106 = 0.1056 = 10.56%.
Missing informationThe problem asks for the probability that the person is between 67.1 and 68.3 inches.

Let P be the set of integers that are multiples of 3 between 1 and 10 and Q be the set of positive integers that are multiples of 4 and are less than 15. Which of the following list of elements does not belong to the union of P and Q?
A. 5
B. 3
C. 6
D. 4
Answers
The union of the sets P and Q does not have the integer 5 since it is neither a multiple of 3 or a multiple of 4.
P is the set of integers between 1 and 10 and multiple of 3.
∴P = {3,6,9}
Q is the set of positive integers less than 15 and multiple of 4.
∴Q = {4,8,12}
Now the union of the sets P and Q is given by :
P∪Q = {3,4,6,8,9,12}
Now the union of the sets does not contain the integer 5.
Any collection of items, including a set of raw materials, the seven days of the week, several car types, etc., can be categorized as a set.
Any set component counts as an element of the set. Curly brackets are used to write a set. A very basic set would resemble something like this:
Q = {4,8,12}.
Therefore the integer 5 does not belong to the union of P and Q .

Find the measure of the exterior angle.
Answers
The measure of the exterior angle is 139 degrees.
What is the measure of the exterior angle?The sum of the interior angle of a triangle is 180 degree.
The sum of angles on a straight line is 180 degrees.
From the diagram;
Angle 1 = 64 degreesAngle 2 = 75 degreesAngle 3 = ?First, we determine the third interior angle of the triangle.
Angle 1 + Angle 2 + Angle 3 = 180
64 + 75 + Angle 3 = 180
139 + Angle 3 = 180
Angle 3 = 180 - 139
Angle 3 = 41 degrees
Now, angle 3 and the exterior angle forms a angle on a straight line.
Hence;
Angle 3 + Exterior angle = 180
41 + Exterior angle = 180
Exterior angle = 180 - 41
Exterior angle = 139 degrees.
Therefore, 139 degrees is the exterior angle.

In ΔQRS, s = 7.9 cm, ∠Q=125° and ∠R=23°. Find the length of q, to the nearest 10th of a centimeter.
Answers
The length of q, to the nearest 10th of a centimeter, is 8.8 cm.
We are given the following;
In ΔQRS, s = 7.9 cm, ∠Q=125° and ∠R=23°.
The third angle can be calculated using the angle sum property:
angle Q + angle R + angle S = 180 degrees
125 degrees + 23 degrees + angle S = 180 degrees
angle S = 180 - (125 + 23) degrees
angle S = 180 - 148 degrees
angle S = 32 degrees
To find the length of q we shall apply the Sine rule.
q / Sin Q = s / Sin S
q / Sin 125 = 7.9 / Sin 32
by cross multiplication we will get;
q = (7.9 x Sin 125) / Sin 32
q = (7.9 x 0.61) / 0.55
q = 8.8 cm (approximately)
So, the length of q is 8.8 cm.
Thus, the length of q, to the nearest 10th of a centimeter, is 8.8 cm.
