In the first race in the video, the student sprints at a speed of 10 yards per second. The math teacher only runs 3.75 yards per second. In the second race, the teacher is given a 10-yard head start, but their speeds remain the same. In the third race, the teacher is again given a 10-yard head start, but her speed is doubled. The student, however, continues to run at 10 yards per second. The length of each race is 100 yards. In each case, who will cross the finish line first? Will the student catch the math teacher, and if so when?

The median height is less than the mean height.

Option 3 is correct.

The midway value in a given set of figures or data is referred to as the median. To get the average value for a given group of integers, three different metrics are employed in mathematics. The terms are median, mode, and mean. The term "measures of central tendency" refers to these three metrics.

As per the given graph:

Total number of plants = 80

Frequency v/s height of plant is given.

The mean height is 41.9 cm.

To find the median:

Total observations (n) = 25 + 20 + 13 + 10 + 2 + 10

= 80 plants

For median interval:

(n/2) = (80/2)

= 40 plants

Hence, the median interval will be the one where frequency reach 40.

∴ Median lies in the interval of height (30-40) cm.

Hence, the median height is less than the mean height.

The length and width of the rectangle are 10 and 3, respectively.

Let's use "l" to represent the length of the rectangle and "w" to represent the width. From the problem statement, we've got portions of information:

The perimeter is 26. The formulation for the perimeter of a rectangle is P = 2l + 2w. So we are able to write:

2l + 2w = 26

The length is four extra than twice the width. In equation shape:

l = 2w + four

Now we can use substitution to resolve for the length and width. we will alternative the expression 2w + 4 for l within the first equation:

2(2w + 4) + 2w = 26

Simplifying:

4w + 8 + 2w = 26

6w + 8 = 26

6w = 18

w = 3

So the width of the rectangle is three. To discover the length, we're going to substitute w = 3 into the equation for l:

l = 2w + 4 = 2(3) + 4 = 10

So the length of the rectangle is 10.

Thus, the length and width of the rectangle are 10 and 3, respectively.

The OLS estimate of the return to an additional year of schooling is 0.074. This means that for every additional year of schooling, the individual's earnings will increase by 7.4%. This is statistically significant at the 5% level of significance because the t-value is 0.074/0.025 = 2.96, which is greater than the critical value of 1.96.

However, Sharon is not correct in thinking that this is the true return to schooling. This is because there may be other factors that affect earnings that are not included in the model, such as ability or family background. These omitted variables can bias the estimate of the return to schooling.

Sharon could use the information about the starting age and compulsory schooling age to obtain the true return to schooling. This is because these rules create exogenous variation in the amount of schooling that individuals receive. She could use this exogenous variation to estimate the causal effect of schooling on earnings by using an instrumental variables approach. By using the starting age and compulsory schooling age as instruments for years of schooling, she could obtain an unbiased estimate of the true return to schooling.

By the principle of mathematical induction, the statement is true for all positive integers n.

To prove that n^p−n is always divisible by p, we can use the principle of mathematical induction.

When n = 1, we have 1^p - 1 = 0, which is divisible by p.

Assume that the statement is true for n = k, i.e., k^p - k is divisible by p. Now, we need to prove that the statement is also true for n = k+1, i.e., (k+1)^p - (k+1) is divisible by p.

Expanding (k+1)^p using the binomial theorem, we get:

(k+1)^p = k^p + pk^(p-1) + ... + p(k^2) + p(k) + 1

Subtracting (k+1) from both sides gives:

(k+1)^p - (k+1) = k^p - k + pk^(p-1) + ... + p(k^2) + p(k)

Since k^p - k is divisible by p by the induction hypothesis, and all the other terms on the right-hand side are multiples of p, we can conclude that (k+1)^p - (k+1) is also divisible by p.

Therefore, by the principle of mathematical induction, the statement is true for all positive integers n.

We have proved that n^p−n is always divisible by p for any prime p using induction on n.

All of Ben's expressions are erroneous since none of them equal the number 108 degrees. The correct equation is (n-2) x 180 / n.

A polygon is a geometric object with two dimensions and a finite number of sides. A polygon's sides or edges are created by connecting end to end segments of a straight line to create a closed shape. Vertex or corners refers to the intersection of two line segments, which produces an angle.

Step-by-step explanation:

The origin is the point in the center of a graph, where the x- and y-axes intersect. This point is also (0,0).

26. The equation in slope-intercept form is y = 3x + 20.

27. The equation in slope-intercept form is y = (1/4)x - 11.

30. The equation in point-slope form is y - (-3) = -6(x - 2)

31. The equation in slope-intercept form is y = -6x + 9.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

26.

y-8 = 3(x+4)

y - 8 = 3x + 12  (distribute the 3)

y = 3x + 12 + 8 (add 8 to both sides)

y = 3x + 20

The equation in slope-intercept form is y = 3x + 20.

y+5= (1/4)(x-24)

y + 5 = (1/4)x - 6

y = (1/4)x - 6 - 5

y = (1/4)x - 11

The equation in slope-intercept form is y = (1/4)x - 11.

To find the equation of a line with a slope of -6 that goes through (2,-3), we can use the point-slope form.

Point-slope form:

y - y₁ = m(x - x₁) where m is the slope and (x₁,y₁) is the point

The variance of 3X + 2022 is -26.

The variable X in this scenario contains the total number of trials until all odd numbered balls are removed from the box without replacement. In order to find the variance of 3X + 2022, we can use the formula for the variance of a linear transformation: V ar(aX + b) = a^2V ar(X).

In this case, a = 3 and b = 2022, so the formula becomes: V ar(3X + 2022) = 3^2V ar(X) = 9V ar(X).

To find the variance of X, we can use the formula for the variance of a discrete random variable: V ar(X) = E(X^2) - [E(X)]^2.

Since X is the total number of trials until all odd numbered balls are removed, we can find E(X) by calculating the expected value of the number of trials until each odd numbered ball is removed. This can be done using the formula for the expected value of a geometric random variable: E(X) = 1/p, where p is the probability of success.

For the first odd numbered ball, the probability of success is 3/5, so E(X) = 1/(3/5) = 5/3. For the second odd numbered ball, the probability of success is 2/4, so E(X) = 1/(2/4) = 4/2 = 2. For the third odd numbered ball, the probability of success is 1/3, so E(X) = 1/(1/3) = 3/1 = 3.

Therefore, the expected value of X is E(X) = 5/3 + 2 + 3 = 14/3.

To find E(X^2), we can use the formula for the expected value of the square of a geometric random variable: E(X^2) = (2 - p)/p^2.

For the first odd numbered ball, E(X^2) = (2 - 3/5)/(3/5)^2 = (10/5 - 3/5)/(9/25) = 7/5 * 25/9 = 35/9. For the second odd numbered ball, E(X^2) = (2 - 2/4)/(2/4)^2 = (8/4 - 2/4)/(4/16) = 6/4 * 16/4 = 24/4 = 6. For the third odd numbered ball, E(X^2) = (2 - 1/3)/(1/3)^2 = (6/3 - 1/3)/(1/9) = 5/3 * 9/1 = 15.

Therefore, the expected value of X^2 is E(X^2) = 35/9 + 6 + 15 = 170/9.

Now we can find the variance of X: V ar(X) = E(X^2) - [E(X)]^2 = 170/9 - (14/3)^2 = 170/9 - 196/9 = -26/9.

Finally, we can find the variance of 3X + 2022: V ar(3X + 2022) = 9V ar(X) = 9(-26/9) = -26.

Therefore, the variance of 3X + 2022 is -26.

The length of side 'g' is approximately 61.54 inches.

A triangle is a 2-dimensional geometric shape that consists of three line segments or sides and three angles. It is one of the simplest polygonal shapes and is often used in mathematics and geometry to illustrate basic concepts such as area, perimeter, angles, and congruence.

To find the length of side 'g' of ΔFGH, we can use the Law of Sines, which relates the lengths of the sides of a triangle to the sine of their opposite angles. The Law of Sines states that:

a/sin(A) = b/sin(B) = c/sin(C)

Here the lengths of the sides of a ΔABC are a, b, and c, and A, B, and C are the opposite angles.

In this case, we know that the length of side 'f' is 67 inches, and the measures of angles, G and H are 66° and 30° respectively. Let's assume the length of ∠G side is 'g'. Then, using the Sin Law, we can write:

f/sin(F) = g/sin(G) = h/sin(H)

Substituting the given values, we get:

67/sin(F) = g/sin(66) = h/sin(30)

Solving for 'g', we have:

67/sin(F) = g/sin(66°)

g = 67 * {sin(66°) / sin(F)}

To find the measure of angle F, we can use the fact that the sum of the angles in a triangle is 180 degrees. Therefore:

F = 180° - G - H

F = 180 - 66° - 30°

F = 84°

Substituting this value into the equation for 'g', we get:

g = 67 * sin(66°) / sin(84°)

putting the values from Sin table: Sin(66°) = 0.913 and Sin(84°) = 0.994

g = 61.54 inches

Therefore, the length of side 'g' is approximately 61.54 inches.

The coordinates of the fourth vertex of the square are (a, a).



A square is a type of rectangle with all sides equal. The vertices of a square are the points where the sides meet. Since the square is on the coordinate plane, the coordinates of the vertices can be represented as (x, y) where x and y are the x and y coordinates, respectively.

Given the three vertices of the square J(0, 0), K(a, 0), and L(0, a), we can use the properties of a square to find the coordinates of the fourth vertex.

Since J(0, 0) and K(a, 0) have the same y-coordinate, they are on the same horizontal line. Similarly, J(0, 0) and L(0, a) have the same x-coordinate, so they are on the same vertical line.

The fourth vertex must be on the same horizontal line as L(0, a) and on the same vertical line as K(a, 0). This means that the x-coordinate of the fourth vertex is the same as the x-coordinate of K(a, 0), which is a, and the y-coordinate is the same as the y-coordinate of L(0, a), which is a.

Therefore, the coordinates of the fourth vertex are (a, a).

The total surface area of the triangular pyramid is 107 * [tex]\sqrt(3)[/tex]square feet.

Take a triangle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first triangle and when they're taken together, they form a closed object, called as a triangular pyramid.

We are given that;

The length of median from outer triangle to side of the inner triangle is 8 ft

Side of inner equilateral triangle is 12 ft

Now,

First, we can find the height of the outer equilateral triangle using the Pythagorean theorem:

a^2 + (m/2)^2 = b^2

where a is half the length of the side of the inner triangle (6 ft), m is the length of the median (8 ft), and b is the length of the side of the outer triangle (unknown).

b^2 = 6^2 + 8^2/4

b^2 = 36 + 4

b^2 = 40

b = sqrt(40)

b = 2 * sqrt(10)

So the height of the outer triangle is:

h = b * sqrt(3)/2

h = sqrt(30)

Now we can find the area of each equilateral triangle using the formula:

A = (sqrt(3)/4) * s^2

where A is the area and s is the length of the side.

For the inner triangle:

A_inner = (sqrt(3)/4) * 12^2

A_inner = 36 * sqrt(3)

For the outer triangle:

[tex]A_outer = (\sqrt(3)/4) * (2 * \sqrt(10))^2A_outer = 5 * \sqrt(3)[/tex]

Now we can find the area of the base, which is just the area of the inner equilateral triangle:

A_base = A_inner

A_base = 36 * [tex]\sqrt(3)[/tex]

Finally, we can find the surface area of the triangular pyramid by adding the areas of the four triangles and the base:

SA = A_inner + 3 * A_outer + A_base

[tex]SA = 36 * \sqrt(3) + 3 * 5 * \sqrt(3) + 36 * \sqrt(3)SA = 107 * \sqrt(3)[/tex]

Therefore, the surface area of the triangular pyramid will be 107 * [tex]\sqrt(3)[/tex]square feet.

We must multiply the parallelogram's base and height in order to determine its area. We can observe from the photograph that the parallelogram's height is around 3 cm, and its base is about 5 cm. Hence, the parallelogram's area is:

Area = Base x Height

= 5 cm x 3 cm

= 15 [tex]cm^2[/tex]

15 square centimeters is the result of rounding this response to the nearest whole number. F. 14 cm2 is the measurement that most closely approximates the parallelogram's area in square centimeters.

The measure of arc of central angle is 65 degree.

According to the definition of a central angle in geometry, it is the angle that the arc of a circle occupies in its centre. The angle's arms are formed by the two radii. Knowing the ratio of the curve to the circle using the central angle is helpful.

Central angle is the angle which is made from the half of the Centre of the circle by the one radius .

First, Congruent arcs in the circle and Congruent arcs have congruent triangles .

We have JEI = 125

(A). The largest target is Target B since it has the widest radius. (B). The size of Object A is around 44 inches around. (C). Target C has a surface area of around 254 square inches.

The length of a circle and perhaps other circular geometric object is referred to as its circumference. Anything in a double circular shape that is linear in one dimension is the perimeter.

A). We must contrast the radii of the three objects in order to compare their sizes.

Target A consists of a radius of 7 inches and a width of 14 inches.

The radius of Target B is 10 inches.

Target C has a circumference of 18π inches, so we can use the formula C = 2πr to find its radius:

18π = 2πr

r = 9 inches

Target B is the main market since it has the greatest radius.

B). The circumference of a circle is given by the formula C = 2πr, where r is the radius. For Target A, r = 7 inches, so:

C = 2πr

C = 2π(7)

C ≈ 44 inches (using 3.14 to approximate)

Target A's circumference is therefore around 44 inches.

C). The area of a circle is given by the formula A = πr², where r is the radius. For Target C, we know its circumference is 18π inches, so we can use the formula for circumference to find its radius:

C = 2πr

18π = 2πr

r = 9 inches

Target C's area is as follows because of its 9-inch radius:

A = πr²

A = π(9)²

A ≈ 254 square inches (using 3.14 to approximate)

Target C therefore has a surface area of around 254 square inches.
