Answer:

The value of x is D) 90°

Step-by-step explanation:

The sum of interior angles in a quadrilateral is 360°

As the total interior angles in a quadrilateral is 360 to work this out you would first need to work out the total of the angles given You can do this by adding 101 and 75 and 94, this gives you 270. This is because it tells us how much of that 360 degree total has been used.

The next step is to work out the angle of x. You can do this by subtracting the total angles gives of 270 from the total of 360, this gives you 90 degrees. This is because by subtracting it we are isolating the value of x.

1) Add the values of 94, 101, 75.

[tex]101+94+75=270[/tex]

2) Minus 270 from 360.

[tex]360-270=90degrees[/tex]

Answer: Hey! Since the other answer is obviously wrong. Here is the actual answer! (from Khan Academy) .

Step-by-step explanation:

The slope is 3.

Change in y = + 3

Change in x = +1

So, it is not 1/3 but it is 3/1 which is technically 3.

Here is the formula!:

Slope =  rise/run  =  Change in y / change in x.

Always put the y above the x!!! :)

4,7,9 is not a right angle triangle. If it was a right angle triangle then it show work in the formula a^2+b^2=c^2. But 4^2+7^2 doesn't equal 9^2. The hypotenuse or c should be 8.02 to be a right angle triangle.

Answer: 140 m3

Step-by-step explanation:

Multiply the area of the trapezoid face by the length .

Since the area is 20, you multiply it by 7 to get 140

Answer:

140 m^3

Step-by-step explanation:

This is a prism with a trapezoid base.

The volume if a prism is

V = (area of base) * height

The base is the trapezoid in the front face. The height is the distance between bases which is 7 m.

area of trapezoid = (b1 + b2)h/2

In the area of the trapezoid, h is the height of the trapezoid which is the distance between parallel bases. It is 4 m in this case.

V = (area of base) * (height of trapezoid)

V = (8 m + 2 m)(4 m)/2 * 7 m

V = 20 m^2 * 7 m^2

V = 140 m^3

Answer:

[tex]\boxed{x^7+14x^6y+84x^5y^2+280x^4y^3+560x^3y^4+672x^2y^5+448xy^6+128y^7}[/tex]

Step-by-step explanation:

To answer this question, you can use a number pattern that is well-known in algebra & higher mathematics called Pascal's Triangle. However, for simplification reasons, I will use the Binomial Theorem as it is quite difficult to create Pascal's Triangle without just attaching an image. A binomial is any two-term expression that are not like terms (for instance, both are integers that lack a variable).

After constructing Pascal's Triangle, you can use this method to expand a binomial. To do this, it will require a lot of patience and a lot of space.

Using Pascal's Triangle, we can expand the binomial entirely by referencing the exponents given and the coefficients that we have now solved for using Pascal's Triangle.

Referring to the seventh exponent row of the triangle, we can expand the binomial using a formula referred to as the Binomial Theorem.

The binomial theorem states that:

[tex]\large\boxed{(a+b)^{n}=\sum_{k=0}^{n} \binom{n}{k}a^{n-k}b^{k}, \textsf{where} \binom{n}{k}=\frac{n!}{(n-k)!k!} \textsf {\: and \:} n! = 1 * 2 * 3... \textsf{n}}[/tex]

Therefore, we can use this information to begin defining values and expanding the binomial.

We are given an a, b, and n value. These are defined as a = 2y, b = x, and n = 7.

Therefore, [tex](x + 2y)^{7}=\sum_{k=0}^{7} \binom{7}{k}(2y)^{7-k}(x)^{k}[/tex].

Using this information, you can then solve for every k-value. This will be slightly extensive. To solve for each k-value, ignore the summation sign and everything before it. You only need the information that follows the summation sign: [tex]\binom{7}{k}(2y)^{7-k}(x)^{k}[/tex]. This will then extend and allow you to only use the portions of the equation that require factorials.

Be sure that when you get a final answer that you always apply the exponent (k) to the final result.

k = 0

[tex]\binom{7}{0}(2y)^{7-0}(x)^0 = \frac{7!}{(7-0)!0!}(2y)^{7}(x)^{0}\\[/tex]

[tex]\frac{7*6*5*4*3*2*1}{(7*6*5*4*3*2*1)}(2y)^{7}(x)^{0}[/tex]

[tex]1(2y)^{7} = 2y^7=(2y*2y*2y*2y*2y*2y*2y)= 128y^7[/tex]

[tex]\boxed{128y^7}[/tex]

k = 1

[tex]\binom{7}{1}(2y)^{7-1}(x)^{1}=\frac{7!}{(7-1)!1!}(2y)^{6}(x)^1[/tex]

[tex]\frac{7*6*5*4*3*2*1}{6*5*4*3*2*1} (2y)^{6}(x)^{1}[/tex]

[tex]7(2y)^{6}(x)^{1}=448xy^6[/tex]

[tex]\boxed{448xy^6}[/tex]

k = 2

[tex]\binom{7}{2}(2y)^{7-2}(x)^{2}=\frac{7!}{(7-2)!2!}(2y)^{5}(x)^2[/tex]

[tex]\frac{7*6*5*4*3*2*1}{(5*4*3*2*1)(2*1)}(2y)^{5}(x)^2[/tex]

[tex]\frac{42}{2}(2y)^{5}(x)^2[/tex]

[tex]21(2y)^{5}(x)^{2}=672x^2y^5[/tex]

[tex]\boxed{672x^2y^5}[/tex]

k = 3

[tex]\binom{7}{3}(2y)^{7-3}(x)^3=\frac{7!}{(7-3)!3!}(2y)^{4}(x)^{3}[/tex]

[tex]\frac{7*6*5*4*3*2*1}{(4*3*2*1)(3*2*1)}(2y)^4(x)^3[/tex]

[tex]\frac{210}{6}(2y)^4(x)^3[/tex]

[tex]35(2y)^4(x)^3=560x^3y^4[/tex]

[tex]\boxed{560x^3y^4}[/tex]

k = 4

[tex]\binom{7}{4}(2y)^{7-4}(x)^4 = \frac{7!}{(7-4)!4!}(2y)^3(x)^4[/tex]

[tex]\frac{7*6*5*4*3*2*1}{(3*2*1)(4*3*2*1)}(2y)^3(x)^4[/tex]

[tex]\frac{840}{24}(2y)^3(x)^4[/tex]

[tex]35(2y)^3(x)^4=280x^4y^3[/tex]

[tex]\boxed{280x^4y^3}[/tex]

k = 5

[tex]\binom{7}{5}(2y)^{7-5}(x)^5=\frac{7!}{(7-5)!5!}(2y)^2(x)^5[/tex]

[tex]\frac{7*6*5*4*3*2*1}{(2*1)(5*4*3*2*1)}(2y)^2(x)^5[/tex]

[tex]\frac{2520}{120}(2y)^2(x)^5[/tex]

[tex]21(2y)^2(x)^5 = 84x^5y^2[/tex]

[tex]\boxed{84x^5y^2}[/tex]

k = 6

[tex]\binom{7}{6}(2y)^{7-6}(x)^6=\frac{7!}{(7-5)!6!}(2y)^1(x)^6[/tex]

[tex]\frac{7*6*5*4*3*2*1}{(1)(6*5*4*3*2*1)}(2y)^1(x)^6[/tex]

[tex]\frac{5040}{720}(2y)^1(x)^6[/tex]

[tex]7(2y)^1(x)^6=14x^6y[/tex]

[tex]\boxed{14x^6y}[/tex]

k = 7

[tex]\binom{7}{7}(2y)^{7-7}(x)^7=\frac{7!}{(7-6)(7!)}(2y)^0(x)^7[/tex]

[tex]\frac{7*6*5*4*3*2*1}{(1)(7*6*5*4*3*2*1)}(2y)^0(x)^7[/tex]

[tex]\frac{5040}{5040}(2y)^0(x)^7[/tex]

[tex]1(2y)^0(x)^7=x^7[/tex]

[tex]\boxed{x^7}[/tex]

Now, we have to take a look at the original binomial and discover whether or not we are to add or subtract these terms together. The original binomial was [tex](x+2y)^7[/tex], so we will add (that is the operation of the binomial).

Therefore, we will add all of the terms that we started with following algebraic notation (that is, alphabetically and highest exponent to lowest exponent).

[tex]\boxed{x^7+14x^6y+84x^5y^2+280x^4y^3+560x^3y^4+672x^2y^5+448xy^6+128y^7}[/tex]

This is the final expanded binomial (now a polynomial).

Answer:

Mean= $ 1.96

Mode= No mode

Step-by-step explanation:

Mean is the value obtained by dividing the sum of all the observations by their numbers.

Mean is obtained by dividing the total number of the values with the number of values.

Mean= x1+ x2+ x3 + x4/ 4

Mean = $ 1.5 + $ 2.0 + $ 2.15 + $ 2.20/4=  7.85/4=  1.9625or 1.963 or $ 1.96

Mode is the most frequent occurring value in a data set. But since all the values in the given set occur only once the data does not have any mode .

There is no mode because  every value has the same frequency, that is it occurs the same number of times.

Answer:

The perimeter of the triangle could not be 24 - which is our solution.

Step-by-step explanation:

The first approach to this problem that comes to my mind, is to find the most " restricting " triangles possible. By that I mean the largest length of the side greater than 6 and the side less than 6.

The length of the side greater than 6 has to be less than 12 - considering it has to stretch the sum 6 + 6 - by the Triangle Inequality Theorem. Therefore, the most restricting triangle possible to the 1st decimal place should be the following -

{ 6, 5.9, 11.8 } ... the catch here is that this triangle does not need to be composed of lengths being whole numbers. If that was true the most " restricting " triangle would have lengths { 6, 5, 10 } throwing you off track as it's perimeter is 21.

{ 6, 5.9, 11.8 } adds to a sum of 23.7, eliminating answer choice c. Therefore, we can conclude that the perimeter of the triangle can't be 24. In fact this is only to the first decimal place, you could be more specific and go to the 100th decimal place even. Either way, the perimeter of the triangle has to be less than 24.

Step-by-step explanation:

You can make a table of values to find the points that belong to the line and then draw the line through those points. Here are some: (-6, -2), (0, -1), and (6, 5). You can use any value for x in your table. Hope this helps!

Answer:

71.60 cm

Step-by-step explanation:

To round 71.63 to the nearest tenth, consider the hundredths value of 71.63, which is 3 and less than 5. Therefore, the tenths value remains 6 and you get rid of the 3 since it is less than 5.

Answer:

the  circumference is 71.63 but that number rounded to the nearest tenth is 71.60 cm. when a number is rounded to the nearest tenth in a decimal the last two numbers are rounded. because 3 is less than five then that means we turn it into a zero then we get 71.60

The mean absolute deviation tells you how spread out or how clustered around the mean a set of data is. This is the variation in the data. To compare sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean. A lower mean absolute deviation indicates data points are more clustered around the mean.

Answer:

Sample Answer: The mean absolute deviation tells you how spread out or how clustered around the mean a set of data is. This is the variation in the data. To compare sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean. A lower mean absolute deviation indicates data points are more clustered around the mean.

Which did you include in your explanation? Check all that apply. Make sure you have all of them

The mean absolute value is a measure of variation and indicates the spread of the data.

A higher mean absolute deviation indicates that the data points are more spread out from the mean.

A lower mean absolute deviation indicates data points are more clustered around the mean.
