The probability of getting two odd numbers or two even numbers is 50%, since there are an equal number of odd and even numbers.

There are 6 possible outcomes when rolling two dice:

(1,1), (1,2), (2,1), (2,2), (1,3), (3,1).

The probability of getting two odd numbers is

2/6, or 1/3.

The probability of getting two even numbers is also

2/6, or 1/3.

Therefore, the probability of getting either two odd numbers or two even numbers is 2/3.

The probability of getting two odd numbers or two even numbers is 50%. This is because there are an equal number of odd and even numbers, so each outcome is equally likely. This means that the probability of getting two odd numbers or two even numbers is the same as the probability of getting one odd number and one even number. In both cases, the probability is 50%, since each outcome is equally likely. Therefore, the probability of getting two odd numbers or two even numbers is 50% as there are an equal number of odd and even numbers. This is because all possible outcomes are equally likely, and there are an equal number of odd and even numbers, so the probability of getting either two odd numbers or two even numbers is the same.

Answer:

x=12

Step-by-step explanation:

Since b would equal E

We can make an equation.

x^2 -5x = 84

So that can be solved down to

x^2 -5x -84= 0

(x-12)(x+7)=0

x=12

x=-7

Now we see which one equals 84.

(12)^2 -5(12)=84

-7^2-5(-7)=14

therefore 12 is the correct answer and -7 does not work.

The coordinate pairs of vertices  D₅ (△JKL) of  are J'(-15,-10), K'(5,20) and L'(20,10).

What does a math definition of a coordinate plane mean?

A surface with two dimensions known as the coordinate plane is created by two number lines. The x-axis is a single number line that runs horizontally. The y-axis is the name given to the vertical number line that is the other number line.

                              A place known as the origin is where the two axes collide. To graph points, lines, and other things, we can utilize the coordinate plane.

We know that, D₅ (△JKL) means triangle JKL dilated by scale factor 5 with origin as center of dilation.

If a figure is dilated by factor k and origin is the center of dilation, then

    ( x, y )    ⇒ ( kx , ky )

 From the given problem, the rule of dilation is

       ( x , y ) ⇒ ( 5x , 5y )

Now

    J( -3 , -2 ) ⇒ J'( 5(-3), 5(-2)) = J'( -15 , -10 )

  K( 1,4 ) ⇒ K'(5(1) , 5(4)) = K'( 5,20 )

   L( 4,2 ) ⇒ L'(5(4), 5(2)) = L'( 20,10 )

Therefore, the coordinate pairs of vertices  D₅ (△JKL) of  are J'(-15,-10), K'(5,20) and L'(20,10).

[tex]\frac{- 7}{b - y}[/tex]

Step-by-step explanation:

Algebraic manipulation (i.e. a process involving rearranging or rewriting variables and, multiplication or division, to achieve an algebraic expression in a desired form) will be applied:

The expression in the denominator (y - b) will be algebraically manipulated by being multiplied by negative one:

[tex](y - b)[/tex]×[tex](-1)[/tex]

The parenthesis will be expanded by applying the Distributive Law. The derived variables will be rearranged to achieve the desired form of the algebraic expression:

[tex][(-1)(y)] - [(-1)(b)][/tex] = [tex]-y - (-b)[/tex]

                               = [tex]-y + b[/tex]

                               = [tex]b - y[/tex] (Desired form achieved)

∴The multiple factor of negative one will also need to be multiplied with the numerator of the fraction for balance. This is because the negative one (that is being multiplied with the denominator) was NOT present originally:

[tex](-1)[/tex]×[tex](7)[/tex] = [tex]-7[/tex]

∴The desired form of the fraction is:

     [tex]\frac{-7}{b - y}[/tex]

The fraction 7/(y - b) after changing the denominator (b - y) becomes - 7/(b - y).

Fraction is a comparison between two mathematical quantities or numbers in general.

The number which is being compared is called Numerator and the with whom it is compared is called Denominator.

In mathematical words, if a fraction is look like A/B where A and B are two numbers then A is called Numerator and B is called Denominator.  

Here given the fraction is, 7/(y - b)

So here numerator = 7 and denominator = y - b

We have to change the denominator that is (y - b) with (b - y).

Rearranging the fraction we get,

7/(y - b) = 7/[- (b - y)] = - 7/(b - y).

Step-by-step explanation:

Answer:

g = 16c

Step-by-step explanation:

Let's use g (the number of gallons) and c (the number of cups).

Since there are 16 cups in one gallon, the equation can be represented by:

one gallon = 16 cups →

g = 16c.

We use the coefficient to represent the quantity of cups needed to make one gallon.

the assumption being that h(t) is the height of the rock in "t" seconds, so by the time the rock hits the ground h(t) = 0, namely it has reached 0 height because, well, is on the ground :)

[tex]h(t)=36t^2 - 64\implies 0=36t^2 - 64\implies 64=36t^2\implies \cfrac{64}{36}=t^2 \\\\\\ \sqrt{\cfrac{64}{36}}=t\implies \sqrt{\cfrac{16}{9}}=t\implies \cfrac{4}{3}=t\implies 1.\overline{33}=t[/tex]

The fraction of the height of Cleopatra's clock that is the height of Ptolemy's clock is 2/5

A cylinder is a three-dimensional shape that consists of two parallel circular bases connected by a curved lateral surface. The volume of a cylinder is the amount of space contained within the cylinder. It can be calculated using the formula:

Volume of cylinder = πr^2h

Let's denote the height and radius of Cleopatra's water clock as h_c and r_c, respectively, and the height and radius of Ptolemy's water clock as h_p and r_p, respectively. Since both clocks drain uniformly, we can use the formula for the volume of a cylinder to relate the height and radius of each clock to the time it takes to drain:

Volume of Cleopatra's clock =[tex]\mathrm{ \pi r_c^2h_c}[/tex]

Volume of Ptolemy's clock = [tex]\mathrm{\pi r_p^2h_p}[/tex]

Since Cleopatra's clock drains in 4 hours, the rate of draining is (Volume of Cleopatra's clock) / (4 hours), and similarly for Ptolemy's clock. We are given that after 2 hours of draining, both clocks have the same water height. Therefore, we can set the two rates of draining equal to each other and solve for the ratio of heights:

(Volume of Cleopatra's clock) / (4 hours) = (Volume of Ptolemy's clock) / (5 hours)

[tex]\pi r_c^2h_c / 4 = \pi r_p^2h_p / 5[/tex]

[tex]h_c / h_p = (r_p / r_c)^2 \times (5 / 4)[/tex]

We are not given the values of the radii, but we can see that the ratio of heights depends only on the ratio of the radii squared. Therefore, we don't need to know the actual sizes of the clocks, only the ratio of their radii. Let's call this ratio x:

[tex]x^2 = (h_c / h_p) \times(4 / 5)[/tex]

After two hours of draining, the water height in both clocks is the same, so we can set the volume of water in each clock equal to each other:

[tex]\pi r_c^2(h_c - 2h_c/4) = \pi r_p^2(h_p - 2h_p/5)[/tex]

[tex]\pi r_c^2h_c/2 =\pi r_p^2h_p/5*3[/tex]

[tex]r_c^2h_c/2 = r_p^2h_p/15[/tex]

Now, we can solve for the ratio of water heights after each clock has been draining for three hours:

Water height in Cleopatra's clock after 3 hours = [tex]\mathrm{h_c - (3/4)h_c = (1/4)h_c}[/tex]

Water height in Ptolemy's clock after 3 hours = [tex]\mathrm{ h_p - (3/5)h_p = (2/5)h_p}[/tex]

([tex]h_p[/tex]  / (2/5)[tex]h_p[/tex] ) = ((1/4)[tex]h_c / h_c[/tex])

([tex]h_p[/tex]  / (2/5)) = 1/4

[tex]h_p[/tex] = 2/5 * 1/4

[tex]h_p[/tex] = 1/10

Therefore, the fraction of the height of Cleopatra's clock that is the height of Ptolemy's clock is:

[tex]h_p / h_c[/tex]= 1/10 / (1/4) = 2/5

And the fraction of the water height of Ptolemy's clock that is equal to the water height of Cleopatra's clock after each has been draining for three hours is:

[tex]h_c / (2/5)h_p[/tex] = (1/4) / (2/5)(1/10) = (1/4) / (1/20) = 5/4

Hence,

The fraction of the height of Cleopatra's clock that is the height of Ptolemy's clock is: 2/5

The fraction of the water height of Ptolemy's clock that is equal to the water height of Cleopatra's clock after each has been drained for three hours is: 5/4.
