Answer:

I believe it is C or D.  (C) The IQR is the best measurement of spread for games and movies.

(D) The standard deviation is the best measurement of spread for games and movies.

The explanation why it could be D:

Measures of spread are stats that describes how separated are the group of data between each other.

The measures are range, quartiles, variance and standard deviation. Among these measures, the standard deviation is the one that best expresses the variation, dispersion or spread of a set of values, because is based on the difference between each data and the mean, it takes in count each separation.

The explanation why it could be C:

Our both box plots are highly skewed, therefore, the IQR is the best measurement of spread for games and movies and option C is the correct choice.

I believe it is C, my friend. So I would go with C.

I hope this helps.

Answer:

Step-by-step explanation: Only one solution

To solve this, first combine like terms.

6x + 4x - 6 = 24 + 9x

10x - 6 = 24 + 9x

Then move all like terms to one side.

10x - 9x = 24 + 6

x = 30

Answer:

Negative

Step-by-step explanation:

Answer:

a) 0.022084622

b) 0.08163265306

c) 0.13258252147

Answer:

-8h + 582 is your answer. Hope I helped <3

Answer:

B

Step-by-step explanation:

x^2=64  is equal to x1= -8 and x2=8. meaning that x^2=64 has two answers and number line B shows both points of -8 and 8.

Answer:

Option B

Step-by-step explanation:

[tex]x^2=64\\\\\sqrt{x}=\sqrt{64}\\\\\boxed{x=8,-8}[/tex]

Number line 'B' has the points on '8' and ''-8'. It represents the solutions for the equation.

Option B should be the correct answer.

Hope this helps.

Step-by-step explanation:

g(-3) + 13

= (-3) - 2(-3)^2 + 13

= - 3 - 18 + 13

= -8.

for 14 rides its 70 so you already don't have enough

Answer: cost for 14 rides: 110

Cost for r rides:14+5r

Answer:

x=3

Step-by-step explanation:

13= -2 (x+1) +7x            (given)

13+-2x - 2 +7x              (distributive property of multiplication over addition)

13 + 5x -2                     (combine like terms)

15 = 5x                         (addition property of equality)

3 = x                             (division property of equality)

Step-by-step explanation:

13=-2x-2+7x

15=5x

x=3

Answer: 4m²-6m+12 or 2(2m²-3m+6)

Step-by-step explanation:

To find the perimeter, we use the formula [tex]P=2l+2w[/tex]. Since we are given the length and width, you plug them in and solve.

2(6-5m+6m²)+2(2m-4m²)              [distribute]

12-10m+12m²+4m-8m²                  [combine like terms]

4m²-6m+12 or 2(2m²-3m+6)

Now, we know that the perimeter is 4m²-6m+12 or 2(2m²-3m+6).

Answer:

a. [tex]\frac{3}{5} = \frac{1}{5} + \frac{1}{5} + \frac{1}{5}[/tex]  

b. [tex]\frac{3}{5} = \frac{2}{5} + \frac{1}{5}[/tex]

I hope this helps!

Step-by-step explanation:

3/5=1/5+1/5+1/5

3/5=2/5+1/5

Answer

a

Step-by-step explanation:

because submarine b has a bigger negative number so its more further down

Answer:

m= -3

Step-by-step explanation:

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}\\\\\left(x_1,\:y_1\right)=\left(3,\:4\right),\:\\\left(x_2,\:y_2\right)=\left(4,\:1\right)\\\\m=\frac{1-4}{4-3}\\\\m = \frac{-3}{1} \\\\Simplify\\m=-3[/tex]

Answer:

Slope is -3.

Step-by-step explanation:

The equation to get the slope is y2-y1/x2-x1. So, plug in the points to the equation. -7-8/7-3 = -15/5 = -3/1 = -3.

Step-by-step explanation:

Draw a right triangle with one leg value is 4 and the other leg value is 3

The triangle is attached below

To find hypotenuse , use Pythagorean theorem

[tex]c^{2} =a^{2} +b^{2} \\c^{2} =3^{2} +4^{2} \\\\c^{2} =25 \\\\c=\sqrt{25} =5[/tex]

opposite side = 4, adjacent side =3 and hypotenuse = 5

Apply trigonometric ratios

[tex]sin(A)=\frac{opposite}{hypotenuse}=\frac{4}{5}[/tex]

[tex]cos(A)=\frac{adjacent}{hypotenuse}=\frac{3}{5}[/tex]

[tex]tan(A)=\frac{opposite}{adjacent}=\frac{4}{3}[/tex]

[tex]cosec(A)=\frac{hypotenuse}{opposite}=\frac{5}{4}[/tex]

[tex]sec(A)=\frac{hypotenuse}{adjacent}=\frac{5}{3}[/tex]

[tex]cot(A)=\frac{adjacent}{opposite}=\frac{3}{4}[/tex]

Answer:

Basically, this is trying to say that

[tex]a(b+c)=ab+ac[/tex].

15 can be split up into 10 and 5.

And multiplying 3 by 15 is the same as the sum of multiplying 3 by 10 and 3 by 5.

[tex]3*10=30[/tex] (First Box)

[tex]3*5=15[/tex] (Second Box)

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

[tex]30+15=45[/tex]

[tex]3*15=45[/tex]

(Proof that it works)

Answer:

false

Step-by-step explanation:

let's say we have two odd numbers

2k+1 and 2t+1

[tex](2k+1)(2t+1)\\\\=4kt+2k+2t+1\\\\=2(2kt+k+t)+1[/tex]

so we see it's odd

Answer:

false

Step-by-step explanation:

If we can show a counter example, then it would be false

3*5  ( both are odd numbers)

15  ( that is odd)

So it is not a true statement

Answer:

Step-by-step explanation:

4x + 7 = 3x + 14

x + 7 = 14

x = 7

4(7) + 7 + 3(7) + 14

28 + 7 + 21 + 14

35 + 35 = 70
