The measure of each side of the cube will be 15 inches.

The Volume of the cone is the amount of quantity, which is obtained in the 3-dimensional space. Volume is defined as the space occupied by an object in the three-Dimensions. All three parameters are required for the volume like length, width, and height of the cube or Cuboid

The cube has all the sides equal means that the length, width, and height of the cube will be the same. Let's suppose the length, width, and height of the cube is a.

The volume of a cube will be given by the formula:-

Volume = side³ = a³

a³ = 3375

a = ∛3375

a = ∛( 15 x 15 x 15 )

a = 15 cubic inches.

Therefore, the measure of each side of the cube will be 15 inches.

Answer:

y= 2/3x +5

Step-by-step explanation:

(0,5) is the y intercept and the slope is 2/3 so we can use the y intercept form

y = mx+b where m is the slope and b is the y intercept

y= 2/3x +5

Answer:

y= 2/3x+5

Step-by-step explanation:

Okay, to write the equation of a line you need two values. The y intercept and the slope. The y intercept has an x coordinate of zero, and lucky us, the point you were given has an x coordinate of zero so that's done. You were also given the slope, so you don't have to calculate it. Anyways, the formula of a line is written in slope intercept form usually, so y=mx+b. Just fill in the gaps, m= the slope and b=the y intercept. The slope is 2/3, and the y intercept is 5. So, inserting in the variables you get y=2/3x+5.

The area of the the region between the curve and horizontal axis is 5.09 units.

Step-by-step explanation:

First,

(A intersect B) = {1,2,4,5} intersect {1,3,5,7}

= {1,5}

Now,

A'n B = (A) - (A intersect B)

= {1,2,4,5} - {1,5}

= {2,4}

Answer:

In part A, 6 squares made up of 4 units represented an area of 24.

In part B, the prime factorization of 24 gave 24 = 2 ∙ 2 · 2 · 3, which is equal to 4 · 6.

The factor that is a perfect square, in this case 4, determines the size of squares needed for the visual model, and other factor, 6, determines the number of squares of that size.

Answer:

If thrown up with the same speed, the ball will go highest in Mars, and also it would take the ball longest to reach the maximum and as well to return to the ground.

Step-by-step explanation:

Keep in mind that the gravity on Mars; surface is less (about just 38%) of the acceleration of gravity on Earth's surface. Then when we use the kinematic formulas:

[tex]v=v_0+a\,*\,t\\y-y_0=v_0\,* t + \frac{1}{2} a\,\,t^2[/tex]

the acceleration (which by the way is a negative number since acts opposite the initial velocity and displacement when we throw an object up on either planet.

Therefore, throwing the ball straight up makes the time for when the object stops going up and starts coming down (at the maximum height the object gets) the following:

[tex]v=v_0+a\,*\,t\\0=v_0-g\,*\,t\\t=\frac{v_0}{t}[/tex]

When we use this to replace the 't" in the displacement formula, we et:

[tex]y-y_0=v_0\,* t + \frac{1}{2} a\,\,t^2\\y-y_0=v_0\,(\frac{v_0}{g} )-\frac{g}{2} \,(\frac{v_0}{g} )^2\\y-y_0=\frac{1}{2} \frac{v_0^2}{g}[/tex]

This tells us that the smaller the value of "g", the highest the ball will go (g is in the denominator so a small value makes the quotient larger)

And we can also answer the question about time, since given the same initial velocity [tex]v_0[/tex] , the smaller the value of "g", the larger the value for the time to reach the maximum, and similarly to reach the ground when coming back down, since the acceleration is smaller (will take longer in Mars to cover the same distance)

Answer: 2(10+5)

Step-by-step explanation: half of 20 is 10. half of 10 is five and i put them both in parentheses. outside the parenthesis i placed 2 so it is multiplied to the inner set of numbers.

This is because the red and blue lines cross at (0,-2). We don't really need to worry about the y coordinate here. For this problem, all we care about is the x coordinate, which is x = 0.

When x = 0, the outputs of each function f(x) and g(x) are both the same value. So that's why we can say f(0) = g(0). It's the same as saying f(x) = g(x) has the solution x = 0.

Answer:

y= -⅓x +⅓

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

This form is also known as the point-slope form.

Since the slope is given to be -⅓, m= -⅓.

y= -⅓x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= -5, y=2,

2= -⅓(-5) +c

[tex]2 = \frac{5}{3} + c \\ c = 2 - \frac{5}{3} \\ c = \frac{1}{3} [/tex]

Thus, the equation of the line is y= -⅓x +⅓.

Answer:

let the shortest side be 'x' ft

length of second side = x + 6 ft

length of third side = 2(x+6) - 6 ft

perimeter of triangle = 72 feet

shortest side + second side + third side = 72 ft

x + x + 6 + 2(x+6) - 6 = 72

4x + 12 = 72

x = 15

length of shortest side = 15 ft

length of second side = 15 + 6 = 21 ft

length of third side = 2(15 + 6) - 6 = 36 ft

Answer: Approaches to 1.

Step-by-step explanation:

If there are only 3 dice used, then the only chance that the player has to win is when the 3 dice have the same outcome, 6.

The probability will be:

p = (1/6)^3 = 1/216.

Now, if we add one more dice, we still need at least 3 sixes to win, but the other dice can have any other value. so now the probabilities are:

dice 1---- outcome  = 6, prob = 1/6.

dice 2---- outcome  = 6, prob = 1/6.

dice 3---- outcome  = 6, prob = 1/6.

dice 4---- outcome  = any number, prob = 1.

The probability for this arrangement is still:

p = 1/216.

But now we have permutations!.

The dice that can be any number has 4 possible positions, so the actual probability will be:

P = 4*p = 4/216.

Now remember that if we have N elements, the total number of combinations of K elements ( N ≥ K) is:

[tex]C(N, K) = \frac{N!}{(N - K)!K!}[/tex]

if we add other dice, then we will have 5 dices, and 2 of them that can not be 6 that can take any position, then the number of combinations will be:

[tex]C(5, 2) = \frac{5!}{(5 - 2)!2!} = \frac{5*4}{2} = 10[/tex]

Then the probability will be:

P = 10*p = 10/216.

So we can start to see a pattern here, if we have N dices, we still only need 3 of them to be strictly 6, then we have (N - 3) dices that can be any number.

Then the probabilty of winning if you have N dices is:

P = C(N, N - 3)*p = C(N, N - 3)*(1/216)

Then as N increases, we will see that the probability tends to 1, (it actually grows larger than that, but remember that the probability is a number between 0 and 1, so the maximum is 1)

Why? well... if you roll a lot of dice, suppose 1000 of them, is really likely to have at least 3 sixes in there, so as the number of dice increases, also does the probability.

Answer:

A) 0.46452

B) 0.82064

Step-by-step explanation:

We solve for question A and B using z score formula

z = (x - μ)/σ,

where x is the raw score

μ is the population mean

σ is the population standard deviation.

A) What is the probability that a randomly chosen child has a height of less than 52.85 inches?

x = 52.85 inches, μ = 53.5 inches, σ = 7.3 inches

z = (x - μ)/σ

= 52.85 - 53.5 / 7.3

= -0.08904

Using the z table to find the probability of the z score above.

P(x<52.85) = 0.46452

Therefore, the probability that a randomly chosen child has a height of less than 52.85 inches is 0.46452

B) What is the probability that a randomly chosen child has a height of more than 46.8 inches?

x = 46.8 inches, μ = 53.5 inches, σ = 7.3 inches

z = (x - μ)/σ

= 46.8 - 53.5 / 7.3

= -0.91781

Using the z table to find the probability of the z score above.

P(x<46.8) = 0.17936

P(x>46.8) = 1 - P(x<46.8)

= 1 - 0.17936

= 0.82064

Therefore, the probability that a randomly chosen child has a height of more than 46.8 inches is 0.82064
