Answer:

Race and Ethnicity are considered to be social constructs that enable humans to be grouped or categorized. They are sometimes used interchangeably but most argue that they are different and give them different definitions.

Race is generally used to refer to people that have the same physical characteristics such as skin color or the same texture of hair for instance Black and White/Caucasian.

Ethnicity on the other hand relates to people sharing a common culture, language, nation, and/ or tribal heritage for instance, the English, the Irish and the Igbo.

Answer:

The terms race and ethnicity are often used interchangeably throughout society. However, there is a distinct difference between the two. Race refers to a classification system based on inherited physical or biological traits, such as eye, hair, or skin color. In contrast, ethnicity refers to a group of people that can be linked together by common characteristics such as shared experiences, history, culture, or beliefs. Examples of ethnic groups include Native Americans, French Canadians, and Kongos.

Answer:x=5

Step-by-step explanation:

First we do the parenthesis

-4(7+2x)=-7x-33

To get

-28+-8x=7x+-33

and

-8x-28=-7x-33

Then we Add 7x to both sides.

-8x-28+7x=-7-33+7x

-x-28=-33

Then we Add 28 to both sides.

-x-28+28=-33+28

-x=-5

Lastly Divide both sides by -1.

-x/-1=-5/-1

X=5

Answer

Median

Step-by-step explanation:

It should be noted that medians are resistant to outliers.

Outliers simply means the data records which are different from every other record. It escapes normality. The outlier affects mean, inter-quartile range, mode and the range.

It should be noted that the median isn't affected by outliers. The reason for this is that the median depends on the arrangement and the order of the data. For example, when one changes the lowest score in a given set of numbers, the order won't be affected.

Answer:

0.31 - 0.39

Step-by-step explanation:

3/10 = 0.3

2/5 = 0.4

All the values between 0.3 and 0.4 excluding 0.3 and 0.4 (can't be 0.3 or 0.4)

The decimal number that is greater than 3/10 and less than 2/5 will be;

⇒ 0.35

A decimal number is a number that consists of a whole and a fractional part.

Given that;

A decimal number is greater than 3/10 and less than 2/5.

Now,

Let a decimal number = x

So, We get;

⇒ 3/10 < x < 2/5

Since, We have;

⇒ 3/10 = 0.3

⇒ 2/5 = 0.4

Thus, The decimal number that is greater than 3/10 and less than 2/5 is 0.35.

Problem 5

There are 2 answers and they are choice B and choice C

We can tell by looking at the factors. For something like choice B, the factor (x+6) shows up twice, so that means x = -6 is a double root. Something like choice A has roots x = -6 and x = 6 which aren't the same.

========================================

Problem 6

Ted is correct. He set each factor equal to 0 and solved each equation that resulted from doing so.

Note how 3x-2 = 0 turns into 3x = 2 after adding 2 to both sides. Then he divided both sides by 3 to get x = 2/3. That's the first solution. The second solution x = -5 results from solving x+5 = 0. You subtract 5 from both sides.

To fix Maggie's mistake, you just need to correct her steps to mirror Ted's steps.

63 sandwiches

Step-by-step explanation:

Pete and his friend Danny volunteered to bring sandwiches for lunch at a homeless shelter

They brought 7 loaves of bread

Each loaves have 18 slices

They used 2 slices each to make the sandwich

The first step is to calculate the total number of slices

Sinces 7 loaves of bread are used and each of them contain 18 slices then, the total number of slices can be calculated as follows

= 7 ×18

= 126 slices

Therefore since 2 slices of bread is used to make one sandwich then, the number of sandwiches that was made can be calculated as follows

= 126/2

= 63

Hence 63 sandwiches were made for the shelter

Answer:

[tex]g(x) = 2x^2 - 3x - 1[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 2x^2 + 3x - 1[/tex]

Required

Determine g(x), if f(x) is reflected across the y axis

When a function (x,y) is reflected across the y axis, the new function becomes (−x,y).

In other words,

[tex]g(x) = f(-x)[/tex]

Calculating f(-x)

[tex]f(-x) = 2(-x)^2 + 3(-x) - 1[/tex]

[tex]f(-x) = 2x^2 - 3x - 1[/tex]

Substitute g(x) for f(-x)

[tex]g(x) = 2x^2 - 3x - 1[/tex]

Hence;

[tex]g(x) = 2x^2 - 3x - 1[/tex]

Answer:

Largest possible number of sweets in each tray[tex]=4[/tex]

Step-by-step explanation:

Given:

Number of orange-flavored sweets = 36

Number of grape-flavored sweets = 44

To find: largest possible number of sweets in each tray

Solution:

HCF(highest common factor) of two or more numbers refers to the greatest number which can divide the given numbers

To find largest possible number of sweets in each tray, find the HCF(highest common factor) of 36 and 44.

[tex]36=2^{2}\times 3^{2}\\44=2^{2}\times 11[/tex]

So,

[tex]HCF(36,44)=2^{2}=4[/tex]

So,

Largest possible number of sweets in each tray[tex]=4[/tex]

The largest possible number of sweets in each tray is 4.

In order to determine the largest possible sweets in each tray, the highest common factor of the number of sweets have to determined. The highest common factor is the highest factor that is common to two or more numbers.

Factors of 36 =  1, 2, 3, 4, 6, 9, 12, 18, and 36.

Factors of 44 = 1, 2, 4, 11, 22, 44.

Common factors = 1, 2, 4

Highest common factor - 4

Answer:

[tex]21x^4+3y-35x^2+41[/tex] must be subtracted

As you can see, we added -x+2 to this polynomial to obtain a first degree polynomial. (Though really anything with an x would do. For example, 3x, 2221x, or -224x would all work)

Step-by-step explanation:

We have the following polynomial

[tex]21x^4+3y-6x^2+34[/tex]

And need to find a polynomial to subtract from it to get

[tex]29x^2-7[/tex]

This means that if we subtract these two polynomials, we will get our desired polynomial

[tex]21x^4+3y-6x^2+34-(29x^2-7)\\\\21x^4+3y-6x^2+34-29x^2+7\\\\21x^4+3y-35x^2+41[/tex]

Just to be sure, we can then check our work by finding the difference of the first polynomial and the one that we just found

[tex]21x^4+3y-6x^2+34-(21x^4+3y-35x^2+41)\\\\21x^4+3y-6x^2+34-21x^4-3y+35x^2-41\\\\-6x^2+34+35x^2-41\\\\29x^2-7[/tex]

As we got the desired result, we know that this answer is correct.

And now for the second part of the problem. What polynomial must be added to it to obtain a first degree polynomial?

Recall that a first degree polynomial is one that has the total sum of 1. For example the polynomial x+5 is a first degree polynomial, but x+y+5 has a degree of 2.

This means that our desired polynomial needs to only have some amount of x's and constants.

We can do the same thing as the first time and simply subtract our desired result from the first polynomial. For simplicity, let us use the simple polynomial x+2

[tex]21x^4+3y-6x^2+34-(x-2)\\\\21x^4+3y-6x^2+34-x+2\\\\21x^4+3y-6x^2-x+36[/tex]

As you can see, we added -x+2 to this polynomial to obtain a first degree polynomial. (Though really anything with an x would do. For example, 3x, 2221x, or -224x would all work)

Answer:

124 degrees

Step-by-step explanation:

Look at the equation from the information they gave you. Supplementary angles always add up to 180 degrees, so make up the equation of 8x + 12 +  2x + 28 = 180. Simplify to get 10x + 40 = 180. Subtract 40 from both sides to get 10x = 140. Divide both sides by 10, and you will get x=14. Substitute the value of 10 into the variable x in the angle ZWYK to get 8(14) + 12. This will simplify into 112 + 12, which will eventually get you 124 degrees.

Answer:

Step-by-step explanation:

Since angles ZWYX and ZZYX are supplementary it means that the sum of their angles sum up to 180°

To find mZWYX we must first find x

To find x add ZWYX and ZZYX and equate them to 180 to find x

That's

ZWYX + ZZYX = 180

8x + 12 + 2x + 28 = 180

10x + 40 = 180

10x = 180 - 40

10x = 140

Divide both sides by 10

x = 14°

From the question

mZWYX = 8x + 12

Substitute the value of x into the expression

We have

mZWYX = 8(14) + 12

= 112 + 12

We have the final answer as

See the attached sketch. Let [tex]\beta[/tex] denote angle ABC and [tex]\beta'[/tex] denote angle CBD. Then [tex]\beta'=2\beta[/tex].

From the sketch, we see that

[tex]\tan\beta=\dfrac15[/tex]

[tex]\tan(\beta+\beta')=\tan(3\beta)=\dfrac{AD}5[/tex]

Write [tex]\tan(3\beta)[/tex] in terms of [tex]\tan\beta[/tex]. Recall the angle sum identity for tangent:

[tex]\tan(x+y)=\dfrac{\tan x+\tan y}{1-\tan x\tan y}[/tex]

This gives us

[tex]\tan(3\beta)=\dfrac{\tan\beta+\frac{2\tan\beta}{1-\tan^2\beta}}{1-\tan\beta\cdot\frac{2\tan\beta}{1-\tan^2\beta}}=\dfrac{\tan\beta(\tan^2\beta-3)}{3\tan^2\beta-1}[/tex]

and plugging in [tex]\tan\beta=\frac15[/tex] leaves us with

[tex]\tan(3\beta)=\dfrac{37}{55}[/tex]

and so AD = 5 * 37/55 = 37/11.
