Answer:

Dante most likely asked the students if they should change the school mascot. This is a statistical question because the question can be answered by data that varies.

Step-by-step explanation:

You can see that the results for this question are either "yes" or "no". This means that Dante asked a question with a yes or no answer related to changing the mascot. This question was probably something along the lines of whether or not the mascot should be changed.

The definition of a statistical question is "a question that should have different answers". Therefore, this is a statistical question because the answers will be different from student to student.

Answer:

No, 16i^2+8i+15

Step-by-step explanation:

No, she did not square it properly.

(a+b)^2=a^2+2ab+b^2

So in this case, a=3, and b=4i

(3+4i)^2

= 3^2+2(3*4i)+(4i)^2

=9+6+8i+16i^2

=15+8i+16i^2

= 16i^2+8i+15

Answer:

Answer:

6/5, 0.3815, 97%

Step-by-step explanation:

6/5 = 1.2 = 12%

0.3815 * 100 = 38.15%

97%

Answer:

.3815, 97%, 6/5

Step-by-step explanation:

To keep this simple, just convert all of them into decimals.  6/5= 1.2 if you divide it.  97%= 0.97 because you divide the percent by 100 to get to the decimal.  And finally, .3815 is already a decimal.

Now, you just sort it out.  1.2 is the largest number because it is the only one that is greater than 1.  So that would go last

Now you compare .97 and .3815.  To find out which one is greater, look in the tenths place, or the first digit after the decimal.  9 is obviously greater than 3 so .97 is greater than .3815.

Using this info we found, the smallest is .3815, then 97%, then 6/5

Answer:

HEXAGON:

Using the same methods as for hexagons to the right (I'll let you do the pictures)... 

To find the sum of the interior angles of a dodecagon, divide it up into triangles... There are ten triangles...  Because the sum of the angles of each triangle is 180 degrees...  We get

So, the sum of the interior angles of a dodecagon is 1800 degrees.

Regular Dodecagons:The properties of regular dodecagons:

All sides are the same length (congruent) and all interior angles are the same size (congruent).

To find the measure of the angles, we know that the sum of all the angles is 1800 degrees (from above)...  And there are twelve angles...

So, the measure of the interior angle of a regular dodecagon is 150 degrees.

The measure of the central angles of a regular dodecagon:

To find the measure of the central angle of a regular dodecagon, make a circle in the middle (I'll let you do the picture)...  A circle is 360 degrees around...  Divide that by twelve angles...

So, the measure of the central angle of a regular dodecagon is 30 degrees.

Answer:

5x+12=5x-7

Step-by-step explanation:

If both x's on each are the same number, but with different constants, then the equation is unsolvable. If 5x+12=y, then 5x-7 can't also equal y because they are two different equations.

With all other equations, although some come out irrational, they are solvable and have a solution to them.

[tex]g(x)=-(x-5)^2+4\\=-(x-7)(x-3)[/tex]

Step-by-step explanation:

Given: coordinate grid

To find: the missing number

Solution:

Equation of the parabola that open downwards and is symmetric about y-axis is [tex](x-h)^2=-4p(y-k)[/tex] where [tex](h,k)[/tex] denotes the vertex and focus is at [tex](h,k+p)[/tex]

[tex]g(x)=-(x-.....\,\,\,\,)^2+\left ( ....... \right )\\(x-.....\,\,\,\,)^2=-\left ( g(x)-(....) \right )[/tex]

[tex](x-h)^2=-\left ( g(x)-(k) \right )[/tex]

From the graph, vertex is [tex](5,4)[/tex]. Put [tex](h,k)=(5,4)[/tex]

[tex]g(x)=-(x-5)^2+4\\=-\left [ (x-5)^2-2^2 \right ][/tex]

Use formula [tex]a^2-b^2=(a+b)(a-b)[/tex]

So,

[tex]g(x)=-\left [ (x-5)^2-2^2 \right ]\\=-\left [ (x-5-2)(x-5+2) \right ]\\=-(x-7)(x-3)[/tex]

Answer:

The answer would be A. 55.

Step-by-step explanation:

For the 35% you would take your 200 and divide it by 2 and have two 100's. Since 35% is out of 100% you could take 35 from each 100 and add them together to get 70.

For the 3/8 you would divide and get .375 then you would multiply that by 200 which would give you 75 yellow tags. Then you would add 75 and 70 and get 145. Then subtract 145 from 200 to get 55. Therefore there would be 55 red tags.

The number of Jordan's tags that are red are; A: 55 tags

35% of the 200 tags are blue. Thus;

Number of blue tags = 35% * 200 = 70 tags

3/8 of the 200 name tags are yellow. Thus;

Number of yellow tags = 3/8 * 200 = 75 tags

The remaining tags are red. Thus;

Number of red tags = 200 - (75 + 70)

Number of red tags = 55 tags

Answer:

The answer is 324π m².

Step-by-step explanation:

Given that the surface area of sphere formula is S.A = 4×π×r² where r is radius. The diameter of sphere is 18m so you have to divide it by 2 to find it's radius :

[tex]radius = diameter \div 2[/tex]

[tex]radius = 18 \div 2[/tex]

[tex]radius = 9m[/tex]

Then substitute into the formula :

[tex]s.a = 4 \times \pi \times {r}^{2} [/tex]

[tex]let \: r = 9[/tex]

[tex]s.a = 4 \times \pi \times {9}^{2} [/tex]

[tex]s.a = 4 \times \pi \times 81[/tex]

Answer:

0.8224

Step-by-step explanation:

Data

z-score for x1:

z1 = (x1 - mean)/sd = (63 - 76)/10 = -1.3

z-score for x2:

z2 = (x2 - mean)/sd = (90 - 76)/10 =  1.4

The  proportion of wrist watch prices are between $63 and $90 is:

P(z1 < z < z2) = P(z < 1.4) - P(z < -1.3)

P(z < 1.4) = 0.9192 (see first picture attached)

P(z < -1.3) = 0.0968 (see second picture attached)

P(z1 < z < z2) = 0.9192 - 0.0968 = 0.8224

Answer:

A.) 3

Step-by-step explanation:

Let's start with the numerator:

√36/√4

√36 = ?

We know that 36 is a perfect square, or the product of one number multiplied by itself.

6 x 6 = 36

So, √36 = 6

Let's look at the denominator:

√36/√4

√4 = ?

We know that 4 is also a perfect square.

2 x 2 = 4

So, √4 = 2

Now we have the numerator: 6

And the denominator: 2

Fraction: 6/2

If we simplify this fraction, we are left with 3 because 6 divided by 2 is 3.

Therefore, the first answer is correct.

Answer: 6.28 inches.

Step-by-step explanation:

Formula :

i) Area of sector : [tex]A=\dfrac{x}{360}\times\pi r^2,[/tex], where x = central angle and r is radius

ii) Length of arc : [tex]l=\dfrac{x}{360}\times2\pi r[/tex]

Given , r= 6 in.

A = [tex]3\pi[/tex] inches

Put these values in (i) , we get

[tex]3\pi =\dfrac{x}{360}\times\pi (3)^2\\\\\Rightarrow\ 1=\dfrac{x}{120}\\\\\Rightarrow\ x=120^{\circ}[/tex]

Now , put values of x and r in (ii) , we get

[tex]l=\dfrac{120}{360}\times2\pi(3)\\\\\Rightarrow\ l=2\pi = 2(3.14)=6.28\text{ inches}[/tex]

Hence, the length of the arc is 6.28 inches.
