The probability that one toss will come up heads and the other will come up tails when you flip a coin two times is 50%.

Imagine you've got a coin, and you flip it two times. Once you flip a coin, it can either arrive on heads (the side with a confront) or tails (the side with the hawk, in the event that it's a US quarter).

On the off chance that you flip the coin two times, there are four distinctive conceivable ways the coin can arrive:

heads-heads (HH),

heads-tails (HT),

tails-heads (TH),

and tails-tails (TT).

Presently, out of these four conceivable results, the HT and TH results have one hurl(toss) that comes up heads and the other hurl that comes up tails. So, we're curious about the likelihood of getting either HT or TH.

Since there are four conceivable results and two of them are HT and TH, the likelihood of getting one hurl that comes up heads and the other that comes up tails is 2 out of 4, or 50%.

So, in the event that you flip a coin two times, there's a 50-50 chance that you'll get one hurl that comes up heads and the other that comes up tails

Hence, the likelihood that one hurl will come up heads and the other will come up tails after you flip a coin two times is 2 out of 4, or 50%.

Current world population is 7.64 billion.

Number of people in developed nations :

\(n = \dfrac{7.64\times 17}{100}\\\\n=1.3\ billion\)

Now, per person in developed country eats 100 kg of meat .

So, 1.3 Billion people will eat :

\(M =1.3\times 100\ billion\ kg\\\\M=130\ billion\ kg\)

Therefore, meat consumed in the developed world in 1 year is 130 billion kg.

Each side of cube is 100 cm.

In Maths or in Geometry, a Cube is a solid three-dimensional figure, which has 6 square faces, 8 vertices and 12 edges. It is also said to be a regular hexahedron.

Given that,

Volume of cube = 1 cubic meter

We know that,

1 m = 100 cm

Also  volume of cube = \(a^{3}\)

Then,

Volume of cube = 1000000 cm

                   \(a^{3}\)  = \(100^{3}\)

Using the concept of ratio and proportion, the vendor sold 56 cups of hot cider.

The word "proportion" often denotes a portion, share, or sum that is in comparison to a whole. Two ratios are in proportion when they are equal, according to the proportional idea. When an equation or a statement to that effect is used, two ratios or fractions are equal.

A percentage is a mathematical comparison of two numbers. In terms of proportion, two sets of given numbers are said to rise or decrease in the same ratio if they are directly proportionate to one another.

Cider supplied by the street seller for value = x for 35

= x/35

The cider's ratio is 8:5,

The measure of the other acute angle in the right triangle is 65 degrees.

In a right triangle, one of the acute angles measures 90 degrees, which is the right angle. The sum of the measures of the two acute angles in a right triangle is always 90 degrees.

Given that one of the acute angles measures 25 degrees, we can find the measure of the other acute angle by subtracting 25 degrees from 90 degrees:

Measure of the other acute angle = 90 degrees - 25 degrees

Measure of the other acute angle = 65 degrees

Therefore, the measure of the other acute angle in the right triangle is 65 degrees.

The volume is (8π/3) cubic units.

To find the volume of the solid enclosed by the paraboloid z = 3 + x² + (y − 2)²and the planes z = 1, x = −2, x = 2, y = 0, and y = 2, we need to use a triple integral.

The limits of integration for x, y, and z are as follows:

-2 ≤ x ≤ 2

0 ≤ y ≤ 2

1 ≤ z ≤ 3 + x² + (y − 2)²

Therefore, the triple integral for the volume is:

V = ∫∫∫ (3 + x² + (y − 2)²- 1) dx dy dz, where the limits of integration are as given above.

Simplifying this integral, we get:

V = ∫∫∫ (x² + (y − 2)²) dx dy dz

Using cylindrical coordinates, we can express x and y in terms of r and theta:

x = r cos(theta)

y = r sin(theta)

The limits of integration for r and theta are:

0 ≤ r ≤ 2

0 ≤ theta ≤ 2π

Substituting these values into the triple integral, we get:

V = ∫∫∫ r² dr dtheta dz

Integrating with respect to r and theta first, we get:

V = ∫0² ∫0^2π (r²) dtheta dr ∫1^(3 + r²- 4r sin(theta)) dz

Simplifying the innermost integral, we get:

V = ∫0²∫0^2π (r²) dtheta dr (2 + r² - 4r)

Evaluating the integrals, we get:

V = ∫0^2 (2πr²  - 4π\(r^3\) + (4/3)\(r^4\)) dr

V = (8π/3)

Therefore, the volume of the solid enclosed by the paraboloid z = 3 + x² + (y − 2)² and the planes z = 1, x = −2, x = 2, y = 0, and y = 2 is (8π/3) cubic units.

The student that has   the highest probability to find that the actual number of times his or her coin lands heads up most closely matches the predicted numberof heads-up landings is Collin.

Let's calculate the expected number of heads-up landings for each student  -

Ana = 0.5 * 50 = 25

Brady  = 0.5 * 10 = 5

Collin = 0.5 * 80 = 40

Deshawn  = 0.5 * 20 = 10

Step-by-step explanation:

I just took the quiz !!

The midpoint approximation of the area under the curve f(x) = 2x(x - 4)(x - 8) over the interval [0, 4) with 4 subintervals is 0. To approximate the area under the curve using a midpoint approximation, we divide the interval [0, 4) into four subintervals of equal width.

The width of each subinterval is (4 - 0) / 4 = 1.

Now, we need to evaluate the function at the midpoint of each subinterval and multiply it by the width of the subinterval.

The midpoints of the subintervals are: 0.5, 1.5, 2.5, and 3.5.

Evaluating the function at these midpoints, we get:

f(0.5) = 2 * 0.5 * (0.5 - 4) * (0.5 - 8) = 6

f(1.5) = 2 * 1.5 * (1.5 - 4) * (1.5 - 8) = -54

f(2.5) = 2 * 2.5 * (2.5 - 4) * (2.5 - 8) = 54

f(3.5) = 2 * 3.5 * (3.5 - 4) * (3.5 - 8) = -6

Now, we calculate the sum of these values and multiply it by the width of the subinterval:

Area ≈ (6 + (-54) + 54 + (-6)) * 1 = 0.

Therefore, the midpoint approximation of the area under the curve f(x) = 2x(x - 4)(x - 8) over the interval [0, 4) with 4 subintervals is 0.
