Answer: 5

times are properly represented on the chart, the other represents other possible colored teams

Step-by-step explanation:

There are 6 colors in the key, indicating there are at least 6 teams. But we only have a formal data set of 5 of those colors, therefore representing 5 teams.

The number of teams represented by each color in the pie chart are as follows:

Black: 24%, Navy blue: 21%, White: 19%, Gray: 16%, Maroon: 8%, Other: 12%

The pie chart shows that the dominant uniform color in the dataset is black, with 24% of teams represented by that color. This is followed by navy blue (21%), white (19%), gray (16%), and maroon (8%). The remaining 12% of teams are represented by a variety of other colors.

Here is a table showing the number of teams represented by each color:

Color | Number of teams

Black 24%

Navy blue 21%

White | 19%

Gray | 16%

Maroon | 8%

Other | 12%

Please note that the pie chart does not specify the total number of teams in the dataset, so it is not possible to say exactly how many teams are represented by each color. However, we can estimate that approximately 24% of the teams are black, 21% are navy blue, 19% are white, 16% are gray, 8% are maroon, and 12% are represented by a variety of other colors.

Answer:

B

Step-by-step explanation:

The angle on the circumference is half the angle subtended at the centre by the arc CB, that is

∠CAB = 0.5 × ∠COB = 0.5 × 96° = 48° → B

m∠CAB is 48° given that point O is the center of the circle and ∠COB is 96°. This can be obtained by using the circle theorem.

Given that, ∠COB = 96°

By applying Circle theorem, we can say that

                                 ∠COB = 2∠CAB

                                      96° = 2∠CAB

                                 ∠CAB = 96°/2 = 48°

                                 ∠CAB = 48°

Hence m∠CAB is 48° given that point O is the center of the circle and ∠COB is 96°.

Answer:

The product is 25

Step-by-step explanation:

we know that

The complex number z1 is equal to

z1=(-4-3i)

we know that

To find the complex conjugate of (-4 - 3i) we change the sign of the imaginary part

so

The conjugate is equal to (-4+3i)

therefore

[tex](-4-3i)(-4+3i)=16-9(-1)=25[/tex]

Answer:

[tex](-4-3i) (- 4 + 3i) = 25[/tex]

Step-by-step explanation:

Notice in the graph that z1 has a real component of -4 and an imaginary component of -3.

Then we know that:

[tex]z_1 = -4-3i[/tex]

By definition for an imaginary number of the form [tex]a-bi[/tex] its conjugate will always be the number [tex]a + bi[/tex]

So the conjugate of [tex]z_1[/tex] is:

[tex]-4 + 3i[/tex]

The product of both numbers is:

[tex](-4-3i) (- 4 + 3i) = 16-12i + 12i-9i ^ 2\\\\(-4-3i) (- 4 + 3i) = 16-9 (-1)\\\\(-4-3i) (- 4 + 3i) = 16 + 9\\\\(-4-3i) (- 4 + 3i) = 25[/tex]

Final answer:

To find (g°f)(-3), we first calculate f(-3) = 2, and then g(2) which equals 16. Therefore, (g°f)(-3) is 16.

Explanation:

The question provided is asking us to compute the composition of two functions, denoted as (g°f)(-3), where f(x) and g(x) are both defined algebraically.

The composition of functions refers to applying one function to the results of another.

To find (g°f)(-3), we first evaluate f(-3) and then use that result as the input for g(x).

Firstly, let's evaluate f(-3):
f(x) = 2x + 8f(-3) = 2(-3) + 8 = -6 + 8 = 2

Now, we evaluate g(2) using the result from f(-3):
g(x) = x⁴g(2) = 2⁴ = 16

Therefore, (g°f)(-3) = g(f(-3)) = g(2) = 16.

[tex]\frac{1215}{32}[/tex]

Step-by-step explanation:

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex], hence

[tex]a_{6}[/tex] = 5 × [tex](\frac{3}{2 )} ^{5}[/tex] = 5 × [tex]\frac{243}{32}[/tex] = [tex]\frac{1215}{32}[/tex]

The sixth term of the geometric sequence is 1215/32 given that the first term a₁=5 and common ratio r=3/2. This can be obtained by using formula for nth term of the geometric sequence.

Sequence is s collection of objects in a particular order and repetitions are allowed.

   Geometric Sequence:

a, ar, ar¹, ..., arⁿ⁻¹ is a geometric sequence, where a is the first term, r is the common ratio and arⁿ⁻¹ is the nth term.

From the definition, nth term of a geometric sequence is arⁿ⁻¹.

Given that, a₁=5 and r=3/2​

To find sixth term, put n=6 ⇒ arⁿ⁻¹=(5)(3/2)⁶⁻¹

                                                       =(5)(3/2)⁵

                                                       =5(3⁵/2⁵)

                                                       =5×(243/32)

                                                       =1215/32

Hence the sixth term of the geometric sequence is 1215/32 given that the first term a₁=5 and common ratio r=3/2.

Ella can make 21 complete envelopes with her available red, white, and blue pages, since the number of complete sets is limited by the blue pages.

Ella has 48 red pages, 25 white pages, and 84 blue pages. She needs to put 2 red pages, 1 white page, and 4 blue pages in every envelope. To find out how many complete envelopes she can make, we need to calculate the number of complete sets of pages she can create based on the quantity of each color she has and the number she needs for each envelope.

For the red pages: 48 red pages / 2 pages per envelope = 24 envelopes

For the white pages: 25 white pages / 1 page per envelope = 25 envelopes

For the blue pages: 84 blue pages / 4 pages per envelope = 21 envelopes

Since the number of envelopes is limited by the color with the least amount of complete sets, Ella can make 21 complete envelopes because she will run out of blue pages after the 21st envelope.

Answer:

(4,0)

Step-by-step explanation:

So we have the system:

-x+5y=-4

4x+4y=16

--------------

We are asked to solve this for elimination.

We aren't totally setup for elimination though.

Both equations are in the same form, the form being ax+by=c form, so we are good there.

Now the other requirement is one the columns that contain variables need to be opposites (you will add) or same (you will subtract).

I'm going to multiply the first equation by 4.  The reason I'm going to do this is because the first column will contain -4x and 4x.  Those are opposites.  When you add opposites, you get 0 (they cancel).

So applying the multiplication of 4 to first equation gives:

-4x+20y=-16

4x+   4y=16

----------------- Add the equations now.

0x+24y=0    Again this is called elimination, because we made it to where a                         variable is canceled when combining the equations.

0x+24y=0

0+ 24y=0

     24y=0

Divide both sides by 24:

         y=0

So using one of the equations (you only need one of them) along with the y=0, let's find x.

I'm going to go with -x+5y=-4 with y=0.

Plugging in the 0 for y gives us:

-x+5y  =-4

-x+5(0)=-4

-x+  0  =-4

-x        =-4

Multiply both sides by -1:

x        =4

The solution is (x,y)=(4,0).

ANSWER

The ordered pair is

(4,0)

EXPLANATION

To solve a simultaneous equation using the elimination method means making the coefficient of one of the variables the same. We then add or subtract to eliminate that variable.

The given system has equations:

[tex] - x + 5y = - 4...(1)[/tex]

[tex]4x + 4y = 16...(2)[/tex]

Divide the second equation by 4

[tex]x + y = 4...(3)[/tex]

Add equation (1) and (3) to eliminate x.

[tex] \implies \: 5y + y = - 4 + 4[/tex]

[tex] \implies \: 6y = 0[/tex]

[tex] \implies \: y = \frac{0}{6} = 0[/tex]

Put

[tex]y = 0[/tex]

into the first equation to get:

[tex] - x + 5 \times 0 = - 4[/tex]

[tex] - x = - 4[/tex]

[tex]\dfrac{(2x^3y)^3}{(4xy^2)^2(xy^3)}\qquad\text{use}\ (ab)^n\ \text{and}\ (a^n)^m=a^{nm}\\\\=\dfrac{2^3(x^3)^3y^3}{4^2x^2(y^2)^2xy^3}\qquad\text{cancel}\ y^3\\\\=\dfrac{8x^{(3)(3)}y^3\!\!\!\!\!\diagup}{16x^2y^{(2)(2)}xy^3\!\!\!\!\!\diagup}\\\\=\dfrac{8\!\!\!\!\diagup^1x^9}{16\!\!\!\!\!\diagup_2x^2y^4x}\qquad\text{use}\ a^na^m=a^{n+m}\\\\=\dfrac{x^9}{2x^{2+1}y^4}\\\\=\dfrac{x^9}{2x^3y^4}\qquad\text{use}\ \dfrac{a^n}{a^m}=a^{n-m}\\\\=\dfrac{x^{9-3}}{2y^4}\\\\=\dfrac{x^6}{2y^4}[/tex]
