The school district have to  purchase 8 laptops for the cost to be the same for both companies.

What is sequence?

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. It has members, just like a set does. The length of the sequence is the number of elements.

Given that the company 1 offers:

The cost of 1 laptop is $425.

The cost of 3 laptop is $475.

The cost of 5 laptop is $525.

The difference of cost 1 laptop to cost 3 laptop = the difference of cost 3 laptop to cost 5 laptop = $50

The company 2 offers:

The cost of 1 laptop is $250.

The cost of 3 laptop is $350.

The cost of 5 laptop is $450.

The difference of cost 1 laptop to cost 3 laptop = the difference of cost 3 laptop to cost 5 laptop = $100

Take the cost as a sequence:

The common difference of first sequence is 50/2 = 25.

The common difference of second sequence is 100/2 = 50.

Assume that the school district needs to buy n computer.

The nth term of a sequence is a + (n - 1)d, where a is the first term, d is common difference.

The nth term of the first sequence is 425 + (n - 1) 25

The nth term of the second sequence is 250 + (n - 1) 50

According to question,

425 + (n - 1) 25 = 250 + (n - 1) 50

425 + 25n - 25 = 250 + 50n - 50

25n - 50n = 250 - 50 - 425 + 25

- 25n = -200

Divide both sides by 25

n = 8

If the data display is strongly skewed right, it means that there are relatively more households with a higher number of children compared to households with a lower number of children. This means that the median value is likely to be higher than the mean value of 3 children per household.

Possible values for the median could be 4, 5, or even higher. It is not possible to determine the exact value of the median without more information about the distribution of the data. However, it is reasonable to assume that the median could be 4 or 5 children per household in this case.

Step-by-step explanation:

The type of reasoning used to prove the remainder theorem is; Deductive reasoning

Logical reasoning involves using a given set of facts or data to deduce other facts by reasoning logically

There are 4 major types of reasoning here and they are;

1) Deductive reasoning; This is defined as a logical process in which a conclusion is based on the concordance of multiple premises that are generally assumed to be true.

2) Inductive reasoning; This is a method of drawing conclusions by going from the specific to the general.

3) Abductive reasoning; This is defined as a syllogism in which the major premise is evident but the minor premise and therefore the conclusion only probable.

4) Reasoning by analogy; This involves using a well known situation to assert something about a less well understood situation

In this case, we are told that since (x - 5) is a factor of the polynomial x² - 25, if he performs the long division (x² - 25) ÷ (x - 5), the remainder would be zero.

Now, this is an example of deductive reasoning because it has used the initial premise to draw a conclusion on the remainder.

Answer:

[tex]\textsf{Improper fraction}: \quad \dfrac{53}{6}[/tex]

[tex]\textsf{Mixed number}: \quad 8\frac{5}{6}[/tex]

Step-by-step explanation:

Definitions

If each bag holds 6 toys and Edgar has 53 toys, to find how many bags Edgar will fill, divide 53 by 6.

To write this as an improper fraction, place 53 as the numerator and 6 as the denominator:

[tex]\implies \dfrac{53}{6}[/tex]

As 53 is a prime number, its only factors are 1 and 53.  Therefore, the improper fraction cannot be reduced any further.

Rewrite 53 as the sum of 48 and 5:

[tex]\implies \dfrac{53}{6}=\dfrac{48+5}{6}[/tex]

[tex]\textsf{Apply the fraction rule} \quad \dfrac{a+b}{c}=\dfrac{a}{c}+\dfrac{b}{c}:[/tex]

[tex]\implies \dfrac{48}{6}+\dfrac{5}{6}[/tex]

Divide 48 by 6:

[tex]\implies \dfrac{6 \cdot 8}{6}+\dfrac{5}{6}[/tex]

[tex]\implies 8+\dfrac{5}{6}[/tex]

Write as a mixed number:

Option B is correct. It is a plot of the independent and dependent variables.

A scatter diagram is a type of plot or graph that uses Cartesian coordinates to display the values of two variables for a set of data. It is a simple yet powerful way to visualize the relationship between two variables.

The points on the plot represent the values of two variables, the independent variable (X-axis) and the dependent variable (Y-axis). Scatter diagrams provide a visual representation of the relationship between the two variables, which makes it easier to identify patterns such as linear or non-linear relationships.

They also can show correlations, or lack thereof, between two or more variables. Additionally, scatter diagrams can provide insight into the strength of the relationship between the two variables as well as how much of the variation in the dependent variable is explained by the independent variable. For example, a correlation coefficient of 1 indicates a perfect linear relationship, while a correlation coefficient of 0 indicates no relationship between the two variables.

Answer:

The ball will return to the ground at t = 16 seconds, so the correct answer is D.

Step-by-step explanation:

To find when the ball will return to the ground, we need to find the time at which the ball's height is equal to 0. We can do this by setting the height equation equal to 0 and solving for t.h = -16t^2 + 100t + 2

0 = -16t^2 + 100t + 2

-2 = -16t^2 + 100t

-0.125t = -2

t = 16

Answer:

B. 6.3 sec

Step-by-step explanation:

To find the time when the ball will return to the ground, we need to find the value of t when h is equal to 0 (since height = 0 means the ball is on the ground). We can do this by substituting 0 for h in the given equation and solving for t.

So, let's start by substituting 0 for h:

h = -16t^2 + 100t + 2

0 = -16t^2 + 100t + 2

-16t^2 + 100t + 2 = 0

This is a quadratic equation, which we can solve using the quadratic formula:

t = (-100 +/- sqrt(100^2 - 4(-16)(2)) ) / (-2(-16))

t = (-100 +/- sqrt(10000 + 128)) / 32

t = (-100 +/- sqrt(10128)) / 32

t = (-100 +/- 100.64) / 32

t = (200.64) / 32

t = 6.3125

Since the ball is projected into the air and then falls back down to the ground, the time when it returns to the ground must be a positive value. Therefore, the solution to the problem is t = 6.3 sec

Whats the problem put a proper question

The amount of interest Maria owes after 6 month of graduation, if she take a subsidized loan of $5,000 and unsubsidized loan of $4,500 is $508.75.

Therefore, the answer is $509.

Subsidized loan

Here, the time period is considered only after graduation, so time period is 6 months, that is 0.5 year. We know simple interest formula where P is the principal amount, r is annual interest rate and n time period in years.

I = P×r×n

Therefore I₁ =  5000 × 0.055 × 0.5

I₁ = 137.5

Unsubsidized loan

Here the time period is considered from the time the loan taken, so time period is one year of graduation plus 0.5 year, i.e. n = 1.5yrs.

Therefore, I₂ = 4500 × 0.055 × 1.5

I₂ = 371.25

Therefore total interest for both the loan is

I = I₁ + I₂

I = 137.5 + 371.25

I = 508.75

I ≈ $509

To determine the dimensions of a rectangular poster that will cover an area represented by 7x² + 3x - 10, we need to find the factors of the expression 7x² + 3x - 10 that will give us the length and width of the poster.

One way to do this is to factor the expression 7x² + 3x - 10 using the difference of squares method. We can write the expression as follows:

7x² + 3x - 10 = (7x² + 3x) - 10

To factor (7x² + 3x) - 10, we can write the expression as the difference of squares:

(7x² + 3x) - 10 = (7x² + 3x + 10) - (10 + 10)

To simplify the expression, we can complete the square for the terms in parentheses:

(7x² + 3x + 10) - (10 + 10) = (7x² + 3x + 10) - 20

To complete the square, we need to add and subtract the square of half the coefficient of the x term, which is (3/2)² = 9/4. We can rewrite the expression as follows:

(7x² + 3x + 10) - 20 = (7x² + 3x + 10 + 9/4) - (20 - 9/4)

To simplify the expression, we can factor the terms in parentheses:

(7x² + 3x + 10 + 9/4) - (20 - 9/4) = [(7x² + 3x + 10 + 9/4) - (20 - 9/4)]

To simplify the expression further, we can factor out a common factor:

[(7x² + 3x + 10 + 9/4) - (20 - 9/4)] = (x + 1)(7x - 10)

From the given options, the expression that represents the area of the rectangular poster is (x+1)(7x-10), which is equivalent to 7x² + 3x - 10. We can verify this by multiplying (x+1)(7x-10) to get 7x² + 3x - 10. Therefore, the correct answer is A (x+1)(7x-10).
