The simplified fraction for 1.667 is 10/6.

To express 1.667 as a fraction, we can follow these steps:

Step 1: Rewrite the decimal as a fraction without the decimal point.

1.667 → 1667

Step 2: Determine the denominator by counting the number of decimal places.

In this case, the decimal has three places, so the denominator will be 1000.

Step 3: Simplify the fraction, if possible.

In this case, the fraction 1667/1000 is already in its simplest form.

Therefore, the simplified fraction for 1.667 is 1667/1000.

Answer:

See attachment

Step-by-step explanation:

If x + y = 180°, the remaining angles can be labelled as illustrated in the diagram provided in the attachment below.

To properly label the diagram so that x° + y° = 180°, you must bear in mind or recall relation between angles formed when two parallel lines are cut across by a transversal line.

x° would be congruent to any angle that is either corresponding or vertical to it.

That is, for the angles labelled x°, such an angle is either corresponding to the given x° or it is vertically opposite to it.

Consequently, where the angle labelled y° forms a linear pair with x°. Linear pair of angles add up to give 180°.

The addition is one of the four fundamental mathematical operations. Blair's bank balance after spending at the grocery store is -$70.

The addition is one of the four fundamental mathematical operations, the others being subtraction, multiplication, and division. When two whole numbers are added together, the total quantity or sum of those values is obtained.

Given that Blair's bank account was overdrawn by $40. Therefore, we can write her balance before spending at the grocery store as,

Blair's bank balance before spending at the grocery store = - $40

Now, Blair spent $30 at the grocery store. Therefore, she further takes $30 from her account. Thus, we can write Blair's bank balance after spending at the grocery store as,

Blair's bank balance after spending at the grocery store

= Blair's bank balance before spending at the grocery store + Spending

= -$40 + (-$30)

= -$40 - $30

= -$70

Hence, Blair's bank balance after spending at the grocery store is -$70.

Answer:

A)What is the product of 2x -5 and 3x^2 + 5x - 7? Write your answer in standard form.

6x³ - 5x² - 39x + 35 = 0

B. Is the product of 2x -5 and 3x^2 + 5x -7 equal to the product of 5x - 2 and 3x^2 + 5x - 7?

No it is not.

Step-by-step explanation:

A)What is the product of 2x -5 and 3x^2 + 5x - 7? Write your answer in standard form.

(2x - 5) (3x² + 5x - 7)

= 2x(3x² + 5x - 7) -5(3x² + 5x - 7)

= 6x³ + 10x² - 14x -15x² - 25x +35

Collecting like terms

= 6x³ +10x² - 15x² - 14x - 25x +35

= 6x³ - 5x² - 39x + 35

In standard form

6x³ - 5x² - 39x + 35 = 0

B. Is the product of 2x -5 and 3x^2 + 5x -7 equal to the product of 5x - 2 and 3x^2 + 5x - 7?

First we find the product of

5x - 2 and 3x² + 5x - 7?

(5x - 2) (3x² + 5x - 7)

5x(3x² + 5x - 7) -2(3x² + 5x - 7)

15x³ + 25x² - 35x - 6x² -10x + 14

Collect like terms

15x³+ 25x² - 6x² -35x - 10x + 14

15x³ + 19x² - 45x + 14 = 0

Hence, the product of 5x - 2 and 3x^2 + 5x - 7

= 15x³ + 19x² - 45x + 14 = 0

The product of 2x -5 and 3x^2 + 5x -7 = 6x³ - 5x² - 39x + 35 = 0

Comparing both products, we can see that

The product of 2x -5 and 3x^2 + 5x -7 ≠ the product of 5x - 2 and 3x^2 + 5x - 7

If the relationship between two quantities is a proportional relationship, this relationship can be represented by the graph of a straight line through the origin with a slope equal to the unit rate. For each point (x, y) on the graph, ž is equal to k, where k is the unit rate. The point (1, k) is a point on the graph.

Step-by-step explanation:

Option D is the correct answer.

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value time the other.

An increase in demand and a decrease in supply will cause an increase in the equilibrium price, but the effect on quantity is unclear.

Reasoning: For any quantity, the 'buyers' places a higher value on the goods, so the 'manufactures' must place higher values in order to distribute the good. Thus the price increases, but the output depends on the size of the two factors and which dominates, (1) pricing, (2) goods.

Answer:

Step-by-step explanation:

There are 64 students with brown eyes and black hair, and 9 students with blue eyes and black hair. A total of 303 students were surveyed, so to find the percentage you would put the number of students with that trait over the total number of students surveyed. 64/303 = 21.1221%, and 9/303 = 2.9702%. 21.1221 - 2.9702 = 18.1519. When you round that to the nearest whole number, you get 18%. Therefore, the percentage of the sample population with brown eyes and black hair is larger than the percentage of the sample population with blue eyes and black hair by 18%.

The data that Patrick is collecting on shoe size is discrete quantitative data. Hence, option B is the right choice.

Qualitative data is information that cannot be counted, quantified, or stated numerically. It is derived from text, voice, and images and is disseminated via data visualization techniques such as word clouds, concept maps, graph databases, timelines, and infographics.

Quantitative data are numerical measurements of values or counts. Quantitative data are numerical variables (e.g. how many; how much; or how often).

These are of two types:

In the question, we are informed that Patrick is collecting data on shoe size.

We are asked what type of data this will be.

As shoe sizes are given in numeric values, it is quantitative data.

And as these numbers are whole numbers, it is discrete quantitative data.

Thus, the data that Patrick is collecting on shoe size is discrete quantitative data. Hence, option B is the right choice.

D. I would expect the means and standard deviations in the two tests to be about the same, but the standard error in Test B should be smaller than in Test A.

Step-by-step explanation:

Options Includes "A.) I would expect the means, the standard deviations, and the standard errors in Test A and Test B to be about the same.

B.) I would expect the means of the two tests to be about the same, but both the standard deviation and the standard error in Test B should be smaller than in Test A .

C.) I would expect the means of the two tests to be about the same, but both the standard deviation and the standard error in Test B should be bigger than in Test A .

D.) I would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be smaller than in Test A.

E.) would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be larger than in Test A.

Reason:

Since we are measuring the same quantity 100 times and 1000 times respectively in both the tests, we would expect the means and standard deviations to not be significantly different from each other. The standard errors would differ, though, since the formula is = Standard deviation/square root of sample size. Since the sample sizes of both the tests are so significantly different, the corresponding standard errors will also be significantly different. More specifically, the standard error of Test B will be smaller than that of Test A.

This question is based on standard deviation.Therefore, the correct option is D i.e. I would expect the means and standard deviations in the two test to be about the same, but the standard error in test B should be smaller than in test A.

Given:

In Test A,make 100 experimental measurements of some quantity. In Test B, suppose you make 1000 experimental measurements of the same quantity.

Options are include here.

Here, we are measuring the same quantity 100 times and 1000 times respectively in both the tests, we would expect the means and standard deviations to not be significantly different from each other.

The standard errors would differ, though, since the formula is

[tex]= \bold{\dfrac{Standard \;deviation}{Square \;root\; of\; sample \;size}}[/tex]

Hence,the sample sizes of both the tests are so significantly different, the corresponding standard errors will also be significantly different. More specifically, the standard error of Test B will be smaller than that of Test A.

Therefore, the correct option is D i.e. I would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be smaller than in Test A.
