What is the result of adding these two equations?
2x + 3y = -5
5x - y = -12
The result of addition of the two equations 2x + 3y=-5 and 5x - y = -12 is 7x + 2y = -17.
We have to add the two equations 2x + 3y = -5 and 5x - y = -12.
In algebra, like terms can be added or subtracted. Two equations can be added by adding their L.H.S to L.H.S and R.H.S to R.H.S. (L.H.S is Left hand side and R.H.S is Right hand side)
Adding the two equations,
2x + 3y + 5x - y = (-5) + (-12)
2x+5x+3y-y= -5-12
7x + 2y = -17
Hence, by adding 2x + 3y = -5 and 5x - y = -12, we get 7x + 2y = -17.

The number of writing instruments in some teachers' desks is displayed in the dot plot. Which is greater the mean or the median? Explain your reasoning using the shape of the distribution.
please help..
30 points
The median is greater than the mean. From the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean.
In the given chart we can deduce the following;
number of instruments that is 5 = 1number of instruments that is 6 = 1number of instruments that is 7 = 1number of instruments that is 8 = 1number of instruments that is 9 = 3number of instruments that is 10 = 4number of instruments that is 11 = 2number of instruments that is 12 = 1These numbers can be listed as follows;
5, 6, 7, 8, 9, 9, 9, 10, 10, 10, 10, 11, 11, 12
The median of these numbers is calculated as;
\(median = \frac{9+ 10}{2} = 9.5\)
The mean of these numbers is calculated as;
\(mean = \frac{5+6+7+8+9+9+9+10+10+10+10+11+11+12}{14} = 9.07\)
Thus, the median is greater than the mean.
Also, from the shape of the distribution, the data set has more values on the left, so we can say it is skewed to the left. In every distribution that is skewed to the left, the median is always greater than the mean. But if the distribution is skewed to the right, the mean is always greater than the median.

Sam wants to build a wooden deck on his patio, which is in the shape of a parallelogram. The
area of the patio is 350 ft2. Find the base. Round your answer to the nearest foot.
Hint : Use A = bh.
Answer is 18.7
We can use fractions and the information that the length of the base is 18.3 feet to find the solution to our problem.
What is a fraction?Fractions are used to represent the parts or elements of a whole or a set of items. A fraction is made up of two parts - the numerator and the denominator.
The numerator is the number at the top of the fraction line and indicates how many equal parts were taken from the total or collection. The denominator is the number at the bottom of the fraction line and represents the total number of identical objects in the collection or the number of equal sections that the whole is divided into.
There are three ways to express a fraction: as a fraction itself, as a percentage, or as a decimal. Each of these three representation methods will be examined.
According to our question-
The patio is 280 square feet in size. locate the base.
Height = 5x Area = 280 feet square
Base = 6x
The parallelogram A's area can be expressed mathematically as;
Base + height equal area.
A = b×h
the values of area, base, and height are substituted.
280 = 5x × 6x = 30x² \sx² = 280/30 \sx = √(280/30)
Given that the base is 6x,
swapping out x's value.
Base = 6x = 6(√(280/30))
Base=18.3 feet

How does this masterpiece speak to the social justice we yearn for
today through ghosts from a distant past?
what can we learn about gender by examining the female characters in
hamilton?
While Hamilton offers valuable insight into the social justice issues we still face today, it is important to continue examining the experiences of marginalized groups from all angles.
The masterpiece in question, Hamilton, speaks to the social justice we yearn for today through its portrayal of ghosts from a distant past. The play examines issues such as race, immigration, and political corruption, all of which are still relevant in modern society. Hamilton also sheds light on the struggles faced by marginalized groups in the past and present, such as women and people of color.
In terms of gender, the female characters in Hamilton play significant roles in the story. Eliza Hamilton, for example, is a strong and intelligent woman who supports her husband Alexander throughout his political career. Angelica Schuyler, Eliza's sister, is also a well-educated and independent woman who challenges the societal norms of her time. Both women serve as examples of the potential for women to make a difference in society, despite the limitations placed on them due to their gender.
However, it is important to note that Hamilton, like many works of historical fiction, has been criticized for its lack of focus on the struggles of women and people of color during the time period it portrays. While the female characters in the play do challenge gender norms, they are still limited in their agency and their stories are often overshadowed by those of the male characters. Therefore, while Hamilton offers valuable insight into the social justice issues we still face today, it is important to continue examining the experiences of marginalized groups from all angles.

suppose sat writing scores are normally distributed with a mean of 488 and a standard deviation of 113 . a university plans to award scholarships to students whose scores are in the top 10% . what is the minimum score required for the scholarship? round your answer to the nearest whole number, if necessary.
Rounding to the nearest whole number, the minimum score required for the scholarship is 633. Therefore, students who score 633 or higher on the SAT Writing test would be eligible for the scholarship at this university.
To find the minimum score required for the scholarship, we'll use the given information about the SAT writing scores being normally distributed with a mean of 488 and a standard deviation of 113. We need to determine the score that represents the cutoff for the top 10% of students.
Step 1: Find the z-score corresponding to the top 10%.
To do this, use a z-table or an online calculator to find the z-score that corresponds to a cumulative probability of 0.90 (since 100% - 10% = 90%). The z-score is approximately 1.28.
Step 2: Use the z-score formula to find the minimum score.
The formula for finding a value (X) in a normal distribution is:
X = μ + Zσ
Where:
μ (mean) = 488
Z (z-score) = 1.28
σ (standard deviation) = 113
Step 3: Plug in the values and calculate the minimum score.
X = 488 + (1.28 * 113)
X = 488 + 144.64
X ≈ 632.64
Round the result to the nearest whole number:
X ≈ 633
So, the minimum score required for the scholarship is 633.

(a) Mathematically, this can be expressed as: MRS = p1/p2, where MRS is the marginal rate of substitution and p1/p2 is the price ratio of the two goods. (b) This condition ensures that the consumer would not be willing to trade more units of the second good for the first good at the given prices, as it would violate the optimality condition for utility maximization.
(a) To show that the indifference curve through an interior solution, denoted as x*, must be tangent to the consumer's budget line, we can use the concept of marginal rate of substitution (MRS) and the slope of the budget line.
The MRS measures the rate at which a consumer is willing to trade one good for another while remaining on the same indifference curve. It represents the slope of the indifference curve.
The budget line represents the combinations of goods that the consumer can afford given their income and prices. Its slope is determined by the price ratio of the two goods.
If x* is an interior solution, it means that the consumer is consuming positive amounts of both goods. At x*, the MRS must be equal to the price ratio for the consumer to be in equilibrium.
Mathematically, this can be expressed as:
MRS = p1/p2
where MRS is the marginal rate of substitution and p1/p2 is the price ratio of the two goods.
(b) If x* ∈ \(R+^2\)and x1* = 0, it means that the consumer is consuming only the second good and not consuming any units of the first good.
In this case, the marginal utility of the second good (MU2) divided by the marginal utility of the first good (MU1) should be less than the price ratio of the two goods (p2/p1) for the consumer to be in equilibrium.
Mathematically, this can be expressed as:
MU2/MU1 < p2/p1
This condition ensures that the consumer would not be willing to trade more units of the second good for the first good at the given prices, as it would violate the optimality condition for utility maximization.

Slope = -1, through point (-3,5)
The equation of the line having slope = -1 and passing through a point (-3, 5) is y = -x + 2 and graph is given below.
The general equation of a line is y = m × x + c, where m is the slope and c is the y-intercept of the line.
Given slope is equal to -1.
Therefore the equation of the required line is y = (-1) × x + c.
Given that this line passes through the point (-3, 5).
Therefore we have 5 = (-1) × (-3) + c
⇒ 5 = 3 + c
⇒ 5 - 3 = c
⇒ 2 = c
⇒ c = 2
Therefore the y-intercept of the required line in cartesian coordinate form is (0, 2).
Therefore the required equation of the line is y = (-1) × x + 2
⇒ y = -x + 2.

An anthropologist is interested in the relationship
between fathers' and sons' heights. She collects a
simple random sample of 25 fathers and 25 sons and
determines that the least-squares regression line is ý = -
2.8+1.1x, where ŷ is the predicted height of each son
and x is the height of his father (both measured in
inches).
One father is 70 inches tall and the residual for his son's
height is 2.5. What is the son's actual height?
O
71.7 inches
O
74.2 inches
O
76.7 inches
O 82.3 inches
Answer:
the son is 76.5 inches
Step-by-step explanation:
We know that the predicted height of the son based on the father's height is given by the equation ŷ = -2.8 + 1.1x, where x is the height of the father. We are also given that the residual for the son's height of one father who is 70 inches tall is 2.5.
The residual is the difference between the actual value of y and the predicted value of y. So we can set up the equation:
y - ŷ = residual
where y is the actual height of the son.
Substituting the given values, we get:
y - (-2.8 + 1.1(70)) = 2.5
Simplifying, we get:
y - 74 = 2.5
y = 76.5
Therefore, the actual height of the son is 76.5 inches.

Step-by-step explanation:
\(7x = (90 + 5x) \times \frac{1}{2} \)
\(7x = {2.5x} + 45\)
\(4.5x = 45\)
\(x = 10\)

The measure of arc EC is 50. Exterior angle theorem is used in the given problem.
What is the sum of a regular polygon's outer angles?The sum of the exterior angles of a regular polygon with any number of sides equals 360°.
The exterior angle of a polygon is the angle of rotation between one extended side and its neighboring side, which is not extended.
Furthermore, because the polygon is regular, even though it has 'n' sides, all the outside angles have the same measure, and hence their measure is (360/n)°.
The measure of arc EC is found as;
\(\rm 7x = (90+5x)\times \frac{1}{2}\\\\ 7x=2.5x+45\\\\ 4.5 x=45 \\\\ x=10\)
From the diagram,he EC is 5x . The measure of arc EC is;
EC=5x
EC=5×10
EC=50
Hence,the measure of arc EC will be 50.
