What is the degree of the second term in this polynomial

The values of x and y will be 100° and 10° when two parallel lines are being cut by a transversal line.

According to the question,

We have a figure where two parallel lines are being cut by a transversal line.

Now, we know that the angles formed on a straight line is 180° and vertically opposite angles are equal.

The sum of consecutive interior angles is 180°.

Now, we will use these three statements in finding the values of x and y.

Now, adding (2x-70)° and (5y)° will give 180° because the angles made are on a straight line.

(2x-70)°+(5y)° = 180°

2x+5y = (180+70)°

2x+5y = 250° .... (1)

Now, (x+30)° will be the interior angle consecutive to 5y° because they are vertically opposite angles.

So, we have:

(x+30)°+5y° = 180°

x+5y = (180-30)°

x+5y = 150°

5y = 150-x

Now, putting this value of 5y in equation 1:

2x+5y = 250

2x+150-x = 250

x+150 = 250

x = (250-150)°

x = 100°

Now, we will find the value of y:

5y = 150-x

5y = 150-100

5y = 50

y = 50/5

y = 10°

(Note that the values of x and y will be in ° because angles are measured in degree.)

Hence, the value of x is 100° and the value of y is 10°.

The elements of the set given by A∩B is {12,18} .

Set theory, a branch of mathematical logic, studies sets, which are essentially collections of objects.

Despite the fact that every form of object may be turned into a set, set theory is a branch of mathematics that primarily deals with issues that are relevant to mathematics as a whole.

The foundation of set theory is a straightforward binary link between an object o and a set A.

If o is a component (or member) of A, it is expressed as o A. When listing members of a set, commas are used to indicate their separation, or brackets are used to surround a property of those parts.

Since sets are objects, they can be connected by the membership relation.

Given set U = {11,12,13,14,15,16,17,18,19,20}

A = {12,14,16,18,20}

B = {12,15,18}

A∩B = {12,18}

A∪B = {12,14,15,16,18,20}

A' = {11,13,15,17,19}

Therefore the elements of the set given by A∩B is {12,18} .

Explanation

For the given data, we will have the following:

We are given grouped data, from which we will obtain the mean and standard deviation

Thus, we will have

From the above,

We have the mean to be approximately 44.68.

For the standard deviation

We will have

Thus, we have the standard deviation to be 10.22

To find the standard deviation of this set of numbers, we will use the formula

let us explain the parts of this formula, as follows:

We will proceed by parts, the first thing to do is find the mean of the data

Calculating the mean

To find the mean, we will sum all the numbers and divide by the total quantity of numbers, as follows:

That is, the mean of the set is 43. Now we proceed to find the difference between the data and the mean, and the add them to the power of two, in symbols we have:

Now we introduce this result into the formula for the standard deviation, we find:

That is, after approximate to the nearest tenth, we found that the standard deviation of the set of numbers is 2.8

put the values,

thus, the correct answer is option C

Solution

For this case we have the following random variable:

X= amount spend on average for groceries by one person

And we have the following properties:

mean= 52

sd= 14

The distribution of the variable is normal

We can find the middle 50% using a graph like this one:

We can find two quantiles from the normal distribution that accumulates 25% of the area on each tail of the distribution and we have:

Z= -0.674 and 0.674

Now we can use the z score formula given by:

So then we have:

Minimum= 52 - 0.674*14 = 42.56

Minimum= 52 + 0.674*14 = 61.44

It's a little bit easy to understand if you put that numbers in a table.. like this

Now, they ask you an integer that represents a change per hour, and they say you that assume a constant change... then we complement the table with different values per hour until arrive at midnight..

now, you can see that you have two points.. with two coordinates, and you can find a line equation assuming that you have a constant change like this case...

that you place in the cartesian axes.. like this..

You know that you put x values in the horizontal line and y values in the vertical line..

for example, we're gonna place the point (2,1) that means that 2 in x axe and 1 in y axe..

The coefficient of the GCF of a set of algebraic terms, wil be the GCF of the coefficients of the terms.

Notice that the coefficients in this case, are 30 and 60.

The greatest comon factor of this set, is 30, since:

On the other hand, the variable x appears with an exponent of 5 in one case and an exponent of 3 in the other case. The greatest common factor for the variable x will be the lowest power, in this case, 3. Notice that:

Then, we can factor out the following:

Notice that each term can be written as a product of this factor:

Therefore, the greatest common factor (GCF) is:

Answer:

4.6

Explanation:

The diagram shown is a right triangle having the following sides;

Opposite = 17

Adjacent = x

Angle of elevation = 75 degrees

Using SOH CAH TOA identity

Tan theta = opposite/adjacent

Tan 75 = 17/x

x = 17/tan 75

x = 17/3.73205

x = 4.6

Hence the value of x to the nearest tenth is 4.6

Equation of 'm'

(y - 6) = - ³/₅ (x - 2)     [point-slope form]

y = - ³/₅ x + ³⁶/₅    [slope-intercept form]

Equation of 'q'

(y - 6) = ⁵/₃ (x - 2)         [point-slope form]

y = ⁵/₃ x + ⁸/₃         [slope-intercept form]

To find the equation for both 'm' and 'q' requires a bit of work. Because neither  'm' nor 'q' has two points to find the slopes of the line, we have to get creative.

The Line 'n' has two points [ (4, 4) & (1, -1) ], and as such we can find the slope of that line. The line 'n' is parallel with 'q' and perpendicular with m.

For finding the slope of 'n'

The slope of the 'n'    =  (y₂ - y₁) ÷ (x₂ - x₁)      

=  (4 - (- 1)) ÷ (4 - 1)  

=  5 ÷ 3

=  ⁵/₃

To estimate the slope of 'q' and 'm'

When two lines exists parallel, they contain the exact slope.

Since 'n' and 'q' exists parallel,

then the slope of q = ⁵/₃

When two lines exists perpendicular, the product of their slopes exists -1. This means that the slopes exists negative-reciprocals of each other.  

Since 'n' and 'm' exists perpendicular

then the slope of m = - ³/₅

Write the equation for 'q' and 'm'

We can now utilize the point-slope form (y - y₁) = m(x - x₁)) to write the equation for the lines

For both 'q' and 'm' let (x₁, y₁) be (2, 6)

Equation of 'm'

(y - 6) = - ³/₅ (x - 2)     [point-slope form]

y = - ³/₅ x + ³⁶/₅    [slope-intercept form]

Equation of 'q'

(y - 6) = ⁵/₃ (x - 2)         [point-slope form]

y = ⁵/₃ x + ⁸/₃         [slope-intercept form]

The linear equation parallel to y = 3x - 2 that passes through the point (4, 6) is:

y = 3*x - 6

Here we want to find a linear equation parallel to:

y = 3x - 2

Now, a general linear equation is:

y = m*x + b

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

Remember that two lines are parallel if and only if the lines have the same slope and different y-intercept.

So our linear equation will be something like:

y = 3*x + c

Now we also want our line to pass through the point (4, 6), then we can replace these values:

6 = 3*4 + c

6 = 12 + c

6 - 12 = c

-6 = c

So the linear equation is:

y = 3*x - 6

The number of tiles required to cover the floor is 2880 tiles.

To solve this problem, we can find the number of tiles by calculating the area of a rectangle:

We have to convert the dimensions from feet to inches will be

1 feet = 12 inches

12 feet = 12 * 12  = 144in

15 feet = 12 * 15  = 180in

The area of the rectangle can be calculated as:

A = l * w

A = 180 * 144

A = 25920in²

The tiles are 9 squared inches, we can divide the area by 9 to find the number of tiles needed:

25920/9=  2880
