Answers
The given table does not represent a function. The correct answer is D. No, because one x-value corresponds to two different y-values.
To determine if the table represents a function, we need to check if every x-value corresponds to exactly one y-value. Let's analyze the given table:
x | y
-------
O | 1
X | 4
2 | 3
3 | 2
3 | 5
4 |
5 |
From the table, we can see that the x-values are not unique. Both the values 3 and 4 appear twice in the x-column, but they have different corresponding y-values.
This violates the definition of a function, which states that each input (x-value) should have only one output (y-value).
Therefore, the given table does not represent a function.
The correct answer is D. No, because one x-value corresponds to two different y-values.

Answers
Answer:
y = negative four-thirds x + StartFraction 31 Over 3 EndFraction
y = 2 x + 7
Step-by-step explanation:
Let x represent the smaller number and y represent the larger number.
Part 1Four times a number added to 3 times a larger number is 31.
It is translated as:
4x + 3y = 31Then, solving for y:
4x + 3y=31 ⇒ 3y= -4x+31 ⇒ y= (-4x+31)/3 = - 4/3x + 31/3⇒ y= - 4/3x + 31/3

The state of Colorado is 4 centimeters long and 2 centimeters wide on a map. A cartographer wants to use a scale factor of 3.5 to enlarge the map. What is the area of the enlarged map?
98 cm2
42 cm2
28 cm2
8 cm2
Answers
Answer: 98 cm²
Step-by-step explanation:
When a cartographer enlarges a map with a scale factor, both the length and the width are multiplied by the scale factor. In this case, the scale factor is 3.5.
Original dimensions of Colorado on the map:
Length: 4 cm
Width: 2 cm
Enlarged dimensions using the scale factor of 3.5:
Length: 4 cm × 3.5 = 14 cm
Width: 2 cm × 3.5 = 7 cm
To find the area of the enlarged map, multiply the enlarged length and width:
Area = Length × Width
Area = 14 cm × 7 cm
Area = 98 cm²
The area of the enlarged map is 98 cm².
To maintain essential electricity, a gasoline generator at a Puerto Rico hospital uses 3 gallons of gasoline per hour. a) How many gallons of gas are needed to fuel the generator for 1 full day? 72 2 points b) How much co2 will be produced by running the generator for 1 full day? 2 points
Answers
The mass of the CO2 produced IS 630 Kg
What is gasoline?Gasoline is a kind of fuel that is composed mostly of isooctane. In most engines, gasoline is widely used hence the demand for the product is high. We know that the combustion of an alkane (of which gasoline is one) would produce carbon dioxide and water according to a balanced reaction equation.
The balanced reaction equation for the combustion of gasoline is shown in the image attached to this answer.
Since a Puerto Rico hospital uses 3 gallons of gasoline per hour, and there are 24 hours in a day, it the follows that 72 gallons of gasoline are used per day. This 72 gallons is the equivalent of 272.88 L
Now;
Given that the density of gasoline = 748.9 g/L
Mass of gasoline = 748.9 g/L * 272.88 L = 204 Kg
Number of moles of gasoline = 204 * 10^3/114 g/mol = 1789.5 moles
If 2 moles of gasoline produces 16 moles of CO2
1789.5 moles produces 1789.5 moles * 16 moles/2 moles = 14316 moles
Mass of CO2 = 14316 moles * 44 g/mol = 630 Kg

What is the sample population ?
A point estimate is a single value used to estimate a population's unknown parameter. The sample proportion (denoted by p), in the context of determining the population proportion, is a widely used point estimate. The sample proportion is determined by dividing the sample's success rate by the sample size.
The sample must be representative of the population for it to be a reliable point estimate of the population proportion. To accurately reflect the proportions of various groups or categories present in the population, the sample should be chosen at random.

Find the measure of the arc or angle indicated.
Answers
The measure of the arc or angle is:
m∠NLM = 60 deg
How to find the measure of the arc or angle indicated?From the given figure, line LN is the diameter. Thus, the measure of arc LN is 180° (semicircle).
Thus, we can say:
arc NM + arc ML = 180°
(3x + 21) + (8x + 16) = 180°
11x + 37 = 180
11x = 180 - 37
11x = 143
x = 143/11
x = 13
arc NM = 8x + 16
put x = 13:
arc NM = 8(13) + 16 = 120°
Recall that:
The measure of inscribed angle is half the measure of its intercepted arc. That is:
m∠NLM = 1/2 * 120°

√-25/√9 please solve
Answers
Step-by-step explanation:
The expression you provided involves taking the square root of a negative number, which results in an imaginary number. In standard real number arithmetic, the square root of a negative number is undefined. However, in the realm of complex numbers, we can define a square root of negative numbers using the imaginary unit "i," where i is defined as the square root of -1.
Let's break down the expression step by step:
√(-25) / √9
The square root of -25 can be written as √(-1 * 25), which can further be simplified as √(-1) * √25.
√(-1) is equal to "i," and the square root of 25 is 5.
So, the expression becomes:
i * 5 / √9
The square root of 9 is 3.
Now, we can simplify further:
i * 5 / 3
Thus, the simplified expression is (5i) / 3, where "i" represents the imaginary unit.

Answers
The orthonormal basis for R² obtained by the Gram-Schmidt process from the basis B = {(6, 8), (1, 0)} is {u₁ , u₂} = {(3/5, 4/5), (4/5, -3/5)}.
What is the Linear Algebra?Linear Algebra is a branch of mathematics that deals with linear equations, linear functions, vectors, matrices, and systems of equations.
To apply the Gram-Schmidt orthonormalization process, we follow these steps:
Let v₁ be the first vector in the given basis.Let u₁ = v₁ / ||v₁||, where ||v₁|| is the norm (magnitude) of v₁.Let v₂ be the second vector in the given basis.Let u₂ be the projection of v₂ onto the subspace orthogonal to u₁, and then let u₂ = u₂ / ||u₂||.Let's apply these steps to the given basis B = {(6, 8), (1, 0)}.
Let v₁ = (6, 8).We have ||v₁|| = √(6² + 8²) = 10, so u₁ = (6/10, 8/10) = (3/5, 4/5).Let v₂ = (1, 0).We need to find the projection of v₂ onto the subspace orthogonal to u₁. This is given by v₂ - ((v₂ × u₁) / (u₁ × u₁)) u1. We have:(v₂ × u₁) = (1, 0) dot (3/5, 4/5) = 3/5
(u₁ × u₁) = (3/5, 4/5) dot (3/5, 4/5) = 1
so the projection of v₂ onto the subspace orthogonal to u1 is:
v₂ - ((v₂ × u₁) / (u₁ × u₁)) u₁
= (1, 0) - (3/5) (3/5, 4/5)
= (1, 0) - (9/25, 12/25)
= (16/25, -12/25)
Finally, we have ||u₂|| = \(\sqrt{(16/25)^2 + (-12/25)^2} = 4/5, \\\\\)
so u₂ = (16/20, -12/20) = (4/5, -3/5).
Hence, the orthonormal basis for R² obtained by the Gram-Schmidt process from the basis B = {(6, 8), (1, 0)} is {u₁, u₂} = {(3/5, 4/5), (4/5, -3/5)}.

Step-by-step explanation:
Let's evaluate each answer choice.
For reference, the data set is 90, 79, 5, 84, 95, 81 , 87, 94
From least to greatest: 5, 79, 81, 84, 87, 90, 94, 95
A. Since the data has many repeated values, the mode best represents the data.
⇒ The data set has no repeated values. Therefore, this answer choice cannot be correct.
B. Since there is an extreme value (5) and no big gaps in the middle of the data, the median best represents the data.
⇒ This choice is correct. 5 is an extreme value. If we were to arrange the data from the least to greatest, the middle numbers would all be around 80 to 90 ( no big gaps).
C. Since there are no extreme values, the mean best represents the data.
⇒This data set does have an extreme value. There is a 5 in the mix of 80s and 90s. So, this answer is not correct.
D. Since there are no extreme values and few repeated numbers, the median best represents the data.
⇒ As previously mentioned, there is an extreme value of 5. We can eliminate this choice.
Therefore, the best answer choice is B. Since there is an extreme value (5) and no big gaps in the middle of the data, the median best represents the data.

Rebecca carries a balance on her credit card each month. Today is the first day of the new, 28-day billing cycle. The current balance is x and the APR is 24%. Rebecca is buying a friend an expensive gift that costs $1,400 that she plans to put on her credit card. This will be her only purchase this month, and she will be making this purchase on the last day
of the month.
Part A
If her finance charge will be $51, write and solve an equation to determine her current balance on her credit card. Show your work.
Part B How much in finance charges can she save by making the purchase on the last day of the billing cycle versus the first day of the billing cycle?
Answers
Part A: If her finance charge will be $51, an equation to determine Rebecca's current credit card balance is x = (51 - 1) ÷ 0.02.
Part B: Rebecca can save $27 in finance charges by making the purchase on the last day of the billing cycle instead on the first day.
What is an equation?An equation is a mathematical statement showing that two or more mathematical expressions share equality in value.
Equations are depicted using the equation symbol (=).
What is a finance charge?A finance charge includes the interest and other fees charged on credit cards.
The finance charge is usually based on a stated APR (annual percentage rate).
The billing cycle for the month = 28 days
Current beginning balance = x
Annual percentage rate (APR) = 24%
Monthly percentage rate (MPR) = 2% (24% ÷ 12)
Purchase on the last day = $1,400
Total finance charge for the month = $51
Finance charge for the last-day purchase = $1 ($1,400 x 2% x 1/28)
Finance charge for the beginning balance = $50 ($51 - $1)
The current beginning balance, x = $2,500 ($50 ÷ 2%)
Equation for current beginning balance, x = 51 - 1 ÷ 0.02
Total finance charge for the last-day purchase = $28 ($1,400 x 2%)
Savings in finance charge by purchasing ont the last day = $27 ($28 - $1)
Thus, Rebecca can save $27 in finance charge when she purchases the $1,400 gift for her friend on the laset day of the billing cycle instead of on the first day.
