keep the first fraction the same. change the division sign to multiply, and flip the 2 over 3 to 3 over 2 and just multiply from there

Answer:

97.60% of the variation in receipt per theater can be explained by the variation in Twitter activity

Step-by-step explanation:

The coefficient of determination can be computed from the data

Movie                Twitter Activity Receipts

The Devil Inside            219509 14763

The Dictator                        6405 5796

Paranormal Activity 3        165128 15829

The Hunger Games         579288 36871

Bridesmaids                        6564 8995

Red Tails                         11104 7477

Act of Valor                         9152 8054

Here twitter activity be the independent variable and Receipts be the response variable.

Using MS Excel for regression analysis

DATA>DATA ANALYSIS>REGRESSION

Selecting twitter activity as X variable and Receipts as Y variable. We get the following output

APEX

Answer:

Step-by-step explanation:

Each of the triangles is similar, so we have ...

  3/5 = (3+x)/20

  x = 20(3/5) -3

  x = 9

__

  4/5 = (4+y)/20

  y = 20(4/5) -4

  y = 12

__

  3/5 = (3 + x + u)/60

  u = 60(3/5) -3 -9

  u = 24

__

  4/5 = (4 +y +v)/60

  v = 60(4/5) -4 -12

  v = 32

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{67}}}}}[/tex]

Step-by-step explanation:

Given,

UV = 19

VW = 4x - 20

UW = 6x - 35

To find : value of UW

First, finding the value of x

Create an equation and solve for x

[tex] \sf{UV + VW = UW}[/tex]

[tex] \longrightarrow{ \sf{19 + 4x - 20 = 6x - 35}}[/tex]

[tex] \longrightarrow{ \sf{ - 1 + 4x = 6x - 35}}[/tex]

[tex] \longrightarrow{ \sf{4x - 6x = - 35 + 1}}[/tex]

[tex] \longrightarrow{ \sf{ - 2x = - 34}}[/tex]

[tex] \longrightarrow{ \sf{ \frac{ - 2x}{ - 2} = \frac{ - 34}{ - 2}}} [/tex]

[tex] \longrightarrow{ \sf{x = 17}}[/tex]

Value of x = 17

Replacing / Substituting the value of x in 6x - 35 in order to find the value of UW

[tex] \sf{UW = 6x - 35 = 6 \times 17 - 35 = 67}[/tex]

UW = 67

Answer:

f^-1(x) = 2x - 10

Step-by-step explanation:

f(x) = 5 + 1/2 x

y = 5 + 1/2 x

x = 5 + 1/2 y

1/2 y = x - 5

y = 2x - 10

f^-1(x) = 2x - 10

Answer:

[tex]\frac{\sqrt{30}}{5}, -\frac{\sqrt{30}}{5}[/tex]

Step-by-step explanation:

We have the equation [tex]-5x^2 + 6 = 0[/tex]

Since we know that any number multiplied by 0 is 0, we can safely make the term [tex]0x[/tex] to add to this.

So our equation now is [tex]-5x^2 + 0x + 6[/tex]

We can now solve for this using the quadratic formula, which is [tex]\frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}}[/tex].

b is the coefficient on the x term, a is the coefficient on the [tex]x^2[/tex] term, and c is the constant.

Let's substitute inside the equation, since we know [tex]a = -5[/tex], [tex]b = 0[/tex] and [tex]c = 6[/tex].

[tex]\frac{{ - 0 \pm \sqrt {0^2 - 4\cdot-5\cdot6} }}{{2\cdot-5}}}\\\\\frac{{ 0 \pm \sqrt {0 -( -120)} }}{{-10}}}\\\\\frac{{ 0 \pm \sqrt {120} }}{{-10}}}\\\\\frac{{\pm \sqrt {120} }}{{-10}}}\\\\[/tex]

[tex]\frac{\sqrt{30}}{5}, -\frac{\sqrt{30}}{5}[/tex]

Answer:

I think the answer would be x = 3, 4, 5, 6 (Anything greater than 3)

The answer is: x ≥ 3

Step-by-step explanation:

I think this is the answer because:

1) Since the sign ≥ means equal to or less than, x has to equal 3 or greater.

2) This is because if x = 3 then, 2 x 3 equals to 6.  6 and 6 are equal. If x = 4 then, 2 x 4 would equal 8. 8 is greater than 6.

3) Since 2x has to be something equal to or greater than 6, x has to equal 3 or something greater than 3.

Hope this helps!

The solution of the inequality 2x ≥ 6 is greater than or equal to three.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The inequality is given as,

2x ≥ 6

Simplify the inequality, then the value of x will be

x ≥ 6/2

x ≥ 3

Thus, the value of the variable x is greater than or equal to three.

Answer:

35

Step-by-step explanation:

140 divided by 4 is 30

We are being told that:

A leaf fell in the river:

We are to determine how many meters the leaf travel per minute.

SO;

Let the number of meters he traveled in one minute be (x).

i.e.

∴

140 meters = 4 minutes

x meters = 1 minutes

By cross multiply and making x the subject of the formula; we have:

[tex]\mathbf{(x) meters = \dfrac{140 meters \times 1 minute}{ 4 minutes}}[/tex]

x = 35 meters

Therefore, we can conclude that the leaf travels a distance of 35 meters per minute.

Answer:

Scientist B

Step-by-step explanation:

1 kg = 2.2 lbs

1L = 2.11 pints

So let's convert Scientist B's data.

3.0lbs salt = 3.0/2.2 = 1.36kg

6 pints water = 6/2.11 = 2.84L water

Scientist A

1kg salt

3.0L water

We now figure out the concentration of salt in water.

Scientist A Scientist B

1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L

So scientist B had a more concentrated solution.
