A. The null hypothesis H₀ and the alternative hypothesis H₁ are:

H₀: μ = 35 minutes       H₁: μ > 35 minutes

B. If the consultant decides not to reject the null hypothesis, she might be making a Type II error.

C. A Type II error would be failing to reject the hypothesis that μ is = to 35 minutes when, in fact, μ is 43 minutes.

A Type II error occurs when the null hypothesis is false, but the test does not reject it.

In this case, the consultant would be concluding that the mean shopping time is 35 minutes, when in fact it is greater than 35 minutes.

Answer: All Irrational numbers are numbers that cannot be expressed as the ratio of two whole numbers.

Step-by-step explanation: AN examples is The number pi and square roots of non-perfect squares are examples of irrational numbers.

We have a equation of a line and want to find the slope and the interception with the y-axis.

We need to write our equation in the form:

Where m is the slope and b is the y-intercept value.

So,

So the slope m=2 and the y-intercept is b=4.

A graph of the line will be:

The slope of a line perpendicular to the line whose equation is x - 2y = -8 is -2.

In Mathematics and Geometry, perpendicular lines are two (2) lines that intersect or meet each other at an angle of 90° (right angles).

From the information provided above, the slope for the equation of line m is given  by:

x - 2y = -8

2y = x + 8

y = x/2 + 4

slope (m) of line m = 1/2

In Mathematics and Geometry, a condition that is true for two lines to be perpendicular is given by:

m₁ × m₂ = -1

1/2 × m₂ = -1

m₂ = -2

Slope, m₂ of perpendicular line = -2

The unknown angle in the cyclic quadrilateral is as follows:

∠R = 86 degrees

The diagram above is cyclic quadrilateral. A cyclic quadrilateral is a four sided shape that can be inscribed into a circle.

The sum of angles in a cyclic quadrilateral is 360 degrees. The opposite angles in a cyclic quadrilateral is supplementary.

Hence, let's find the unknown angle.

∠R = 1 / 2 (92 + 80)

∠R = 1 / 2 (172)

∠R = 86 degrees

Measurement of weight 6 is in ounces and the measurement of weight 170 is in grams.

What is measurement?

An object or event's attributes are quantified through measurement so that they can be compared to those of other things or events. Measurement, then, is the process of establishing how big or small a physical quantity is in relation to a fundamental reference quantity of the same kind.

Given:

Elena has a pet parakeet that weighs 6 when measured in one unit and

170 when measured in a different unit.

We have to find the correct units from grams and ounces for these.

We know that, 1 ounce is greater than 1 gram.

1 ounce = 28.3495 grams

Multiply both sides by 6.

6 ounces = 170.097 grams

Approximate the values to the nearest whole number.

6 ounces = 170 grams

Therefore, 6 ounces = 170 grams.

Hence, measurement of weight 6 is in ounces and the measurement of weight 170 is in grams.

The option A that is 2 days after being planted, the two plants will of the same height( Where the two lines intersect in a graph).

How to know if the lines intersect in the graph of a function?

All the points (and only those points) which lie on the graph of the function satisfy its equation.

Thus, if a point lies on the graph of a function, then it must also satisfy the function.

And after solving both equations if the values of x and y satisfies both equations then they intersect at that values of x and y.

Now,

The expression 8×2 can be used to find the total number of head wraps on the shelf when there are 8 head wraps per shelf and 2 shelves in total, resulting in a total of 16 head wraps.

Expression in mathematics is a combination of symbols and numbers, often using an operation, such as addition, subtraction, multiplication, or division. It can represent a number, a variable, a function, or a mathematical statement. It can also represent a combination of these things. Expressions are used to describe relationships between numbers, variables, and mathematical concepts.

The expression 8×2 can be used to find the total number of head wraps on the shelf when there are 8 head wraps per shelf and there are 2 shelves in total. This expression can be used to calculate the total number of head wraps on the shelves by multiplying 8 (the number of head wraps per shelf) by 2 (the number of shelves). As such, the expression 8×2 can be used to find the total number of head wraps on the shelf when there are 8 head wraps per shelf and 2 shelves in total, resulting in a total of 16 head wraps.

In conclusion, the expression 8x2 can be used to calculate the total number of head wraps on the shelf when there are 8 head wraps per shelf and 2 shelves in total. By multiplying 8 (the number of head wraps per shelf) by 2 (the number of shelves), the total number of head wraps on the shelf can be found, resulting in a total of 16 head wraps.

The statement is true. If A is an m x n matrix, then A transpose is an n x m matrix obtained by interchanging the rows and columns of A.

The greatest number of rows or columns in a matrix that are linearly independent is the matrix's rank. In other words, it is the size of the matrix's row or column space.

Many techniques, including Gaussian elimination and the singular value decomposition (SVD) approach, can be used to determine the rank of a matrix. The fundamental concept behind these techniques is to lower the row echelon form of the matrix, which facilitates counting the number of linearly independent rows or columns.

What is rank of matrix?

The greatest number of rows or columns in a matrix that are linearly independent is the matrix's rank. In other words, it is the size of the matrix's row or column space.

(A) is true because the rank of a matrix is the same as the rank of its transpose. This is because the row space of a matrix is the same as the column space of its transpose.

(B) is true because row equivalence preserves the row space. That is, any linear combination of the rows of B can be obtained as a linear combination of the rows of A, and vice versa.

(C) is true because a linear transformation preserves the properties of vector spaces. That is, if S is closed under addition and scalar multiplication in V, then L(S) will also be closed under addition and scalar multiplication in W.

(D) is true because the dimension of the solution space is equal to the number of free variables, which is n-r, where r is the rank of the coefficient matrix.

It will take them 2.4 hours or 2 hours and 24 minutes to paint the wall working together.

We have,

We can use the formula:

1/Time taken to complete task = Work done / Time

Let's say the work to be done is to paint the whole wall. We can represent the work done by each brother as follows:

Eldest brother's work done in 1 hour = 1/3

Middle brother's work done in 1 hour = 1/4

The youngest brother's work done in 1 hour = 1/6

Now, we can add up their work done in 1 hour:

1/3 + 1/4 + 1/6 = 2/4

Simplifying, we get:

5/12

This means that together, the three brothers can complete 5/12 of the work in one hour.

To find out how long it would take them to complete the whole work

(paint the wall), we can use the same formula:

1/Time taken to complete task = Work done / Time

Let's say the time taken for the three brothers to complete the work is 't'. Then we can write:

1/t = 5/12

Solving for 't', we get:

t = 12/5 hours or 2.4 hours

Therefore,

Complete question is;

Lorenzo wants to know how much it will cost to rent tables and chairs for an event. He investigates renting tables and chairs and decides to use two different companies. Company A $4 per table (seats 4) and a $25 one-time delivery and pickup fee Company B $2 per chair and a $15 one-time delivery and pickup fee Each table seats 4 people, so Lorenzo needs to rent 4 chairs for every table. x = number of tables Cost to rent tables from Company A: f(x) = 4x + 25 Cost to rent chairs from Company B: g(x) = 2(4x) + 15 Which function represents the total cost for Lorenzo to rent x number of tables and the chairs he needs to go with them?

A) 12x

B) 12x² + 40

C) 12x + 40

D) 8x + 40

Answer:

C: 12x + 40

Step-by-step explanation:

We are told that the Cost to rent tables from Company A is;

f(x) = 4x + 25

Also, we are told that the Cost to rent tables from Company B is;

g(x) = 2(4x) + 15

Thus, total cost for Lorenzo to rent x number of tables and the chairs he needs is;

Total = f(x) + g(x)

Total = 4x + 25 + 2(4x) + 15

Total = 4x + 25 + 8x + 15

Total = 12x + 40
