hey there,

< Linear equations are constant. They are not like parabolas so they are not curved but instead are straight, which allows them to be constant. >

Answer: The answer is a Linear Function

Step-by-step explanation:

From the picture provided in this question, we can draw a straight line horizontally and the diagram would be divided into two different shapes, which are,

An isosceles trapezoid and

A quarter circle

The dimensions and area would now be;

The area of the quarter circle also would now be;

The areaof the entire shape therefore is the addition of the area of the trapezoid and that of the quarter circle.

Area = 13 cm + 12.56 cm

Area = 25.56 square centimeters

Answer:

(1, 2 )

Step-by-step explanation:

Given the 2 equations

- 2x - y = - 4 → (1)

x + 2y = 5 → (2)

Multiplying (2) by 2 and adding result to (1) will eliminate x- term

2x + 4y = 10 → (3)

Add (1) and (3) term by term to eliminate x

0 + 3y = 6

3y = 6 ( divide both sides by 3 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (2)

x + 2(2) = 5

x + 4 = 5 ( subtract 4 from both sides )

x = 1

solution is (1, 2 )

Recognize that "at most" means "less than or equal to." Sarah's spending must satisfy ...

  3.50 + a ≤ 9.00

Subtracting 3.50 from both sides gives ...

  a ≤ 5.50 . . . . . . . . . matches the second inequality shown

We need a sample size of at least 2 subjects to estimate the average number of books Americans read each year with a margin of error of 0.57 books and 80% confidence.

To determine the number of subjects needed to estimate the average number of books Americans read each year with a margin of error of 0.57 books and 80% confidence, we can use the formula:

n = (Z * σ / E)^2

Where:
n = sample size needed
Z = Z-value corresponding to the desired level of confidence (in this case, 80% confidence corresponds to a Z-value of 1.28)
σ = standard deviation of the population (unknown in this case)
E = desired margin of error (0.57 books)

Since the standard deviation of the population is unknown, we can use a conservative estimate of 0.5 for σ. Plugging in the values:

n = (1.28 * 0.5 / 0.57)^2
n ≈ (0.64 / 0.57)^2
n ≈ 1.122^2
n ≈ 1.259

Since we can't have a fraction of a subject, we need a sample size of at least 2 subjects to estimate the average number of books Americans read each year with a margin of error of 0.57 books and 80% confidence.

False. A univariate data set is a set of data that only has one variable or category.

In this case, the running times for 500 runners would have multiple variables - the time each runner takes to complete the race. Therefore, it would be a multivariate data set.

Additionally, the term "group starts" suggests that the runners may have been grouped by certain categories or factors, further adding to the complexity of the data set.

The statement that  at the  very basic level, all inferential statistics procedures seek to determine if observed  characteristics are sufficiently deviant from the null hypothesis to justify rejecting it is true.

The alternative hypothesis (H1) is that the two variables have a relationship.

Fundamentally, all inferential statistics processes strive to assess whether the observed (sample) features deviate from the null hypothesis sufficiently to justify rejecting the hypothesis.

Inferential statistics is a statistical strategy that derives the characteristics of a larger population from a small but representative sample. In other words, it enables the researcher to make broad assumptions about a larger group while using a subset of that population as a guideline.

Thickness of the book is ~

Answer:

4 Hours

Step-by-step explanation:

Let's say that the rate of the machines 1/x, because every time they complete an order, it takes them x hours. To find x, we have to add the the rates of the individual machines, which would equal the rate of the machines working together. We know that there are four machines working together at the same rate, and it took them 32 hours.

So:

1/x + 1/x + 1/x + 1/x = 1/32

1/4x = 1/32

4x = 32

x = 8

Thus, the rate of the machines is 1/8.

Now we have to find the time of the order with only half of the machines working together. This time, we don't know the combined rate, so I'll substitute it for y.

1/8 + 1/8 = 1/y

1/4 = 1/y

y = 4

The time taken to complete it is 4 hours.

By applying the formula we got 738 is median credit score of mary.

The median is the middle number in a sorted, ascending or descending, list of numbers

Given credit score  

639 732 790 837 677 744 637 821

First we will arrange data in ascending order

so  ascending order is 637,639,677,732,744,790,821,837

Here total number of terms n= 8

which is even

so median is

\(\frac{(n/2)^{th } observation+(n/2 +1)^{th} observation )}{2}\)

so median

\(=\frac{(8/2)^{th } observation+(8/2 +1)^{th} observation )}{2}\\\\=\frac{(4)^{th } observation+(5)^{th} observation )}{2}\\\\=\frac{732+744}{2}\\\\=\frac{1476}{2}\\\\=738\)

A list of 6 one digit whole numbers with an average of 5, a median of 6, a range of 9, and no mode is

since the numbers will have no mode so they are all different

Assuming the numbers are: a, b. c. d. e. and f

The average is 5

(a + b + c + d + e + f ) / 6 = 5

a + b + c + d + e + f = 30

The median is 6

(c + d)/2 = 6

c + d = 12  (assume c = 5 and d = 7)

range is 9

f - a = 9, since it is a one digit number a range of 9 is possible for 9 - 0

hence a = 0 and f = 9

substituting assumed values to the average

0 + b + 5 + 7 + e + 9 = 30

b + e + 21 = 30

b + e = 9 (let b = 8and e = 1)

hence the numbers are

0, 1, 5, 7, 8, and 9

True , Every matrix transformation is a linear transformation.

Is there a linear transformation for every matrix operation?

Despite the fact that every linear transformation is a matrix transformation, not all linear transformations are matrix transformations.      

                                    Because of this, it's possible that we'll encounter a linear transformation in which we're unable to locate a matrix to carry out the mapping.

What alteration does matrix entail?

In a two-dimensional or three-dimensional space, the transformation matrix converts one vector into another vector, which may be comprehended geometrically.

The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

The value of the monthly payment is given by;

P = PV × i / 1-(1+i)⁻ⁿ

Where,

PV is the present value or the amount of the loan.

i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.

n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.

Therefore,

The value should be used for n, the number of periods over which the loan is repaid;

n = 6 years × 12 months/year = 60 months = 60 periods.

Hence, The value should be used for n, the number of periods over which the loan is repaid in 60 periods.

The range of the function f(x) = -(x + 3)^2 + 7 is all real numbers less than or equal to 7. Correct option is A.

The range of a function represents all possible output values that the function can produce.

The function is a quadratic function with a vertex at (-3, 7), where the value of x that produces the maximum value of the function. Since the coefficient of the squared term is negative, the function is a downward-facing parabola, which means that its range is limited by its vertex.

The maximum value of the function occurs at x = -3, where f(x) = 7. As we move away from the vertex, the value of the function decreases. Therefore, the range of the function consists of all real numbers less than or equal to 7.

Option A) all real numbers less than or equal to 7 is the correct answer, as it represents the maximum value of the function at its vertex (-3, 7), and all values less than this as we move away from the vertex.

Option B) all real numbers greater than or equal to 7 is incorrect, as the function can never produce output values greater than 7.

Option C) all real numbers less than or equal to -3 is incorrect, as the function can produce output values greater than -3 as we move away from the vertex.

Option D) all real numbers greater than or equal to -3 is incorrect, as the function produces values less than -3 as we move away from the vertex.
