d = 1.4 t + 30

Step-by-step explanation:

Head start means any advantage achieved or advantage gained in any race or competition.

In the context, the runner is gained a head start of 30 meter from the starting point.

It is also given that the speed with which the runner is running is 5.0 km per hour.

Therefore, the equation that gives the distance covered by the runner from his start line at any time in seconds is given by d = 1.4 t + 30.

The number of feet in the length of the handrail is 17.3 feet.

Pythagorean theorem, is a geometric theorem that the total of a squares on the sides of a right triangle equals the square upon that hypotenuse (a side opposite its right angle)—or, using familiar algebraic notation, the sum of squared on the hypotenuse equals the square also on hypotenuse.

A spiral would be a shape that wraps around and around with each curve being higher or lower than the one before it.

Now, according to the question;

The simplest way to understand this is to assume that we may "unfold" this spiral to form a rectangle.

Its bottom part of rectangle is simply an arc length of a 3 ft radius circle spun around 270°= (3/4) of a full revolution.

Thus,

= (3/4)× (2\(\pi\)) ×(3)  

=  (9/2)×\(\pi\) ft

=   4.5×\(\pi\)  ft

The height of the staircase will be the side of rectangle = 10ft.

And the rectangle's diagonal will correspond to the length of a railing.

To solve this, we can apply the Pythagorean Theorem.

Handrail length = √ [ (4.5 ×\(\pi\))² + 10² ]  

Handrail length ≈  17.3 ft

Therefore, the the number of feet in the length of the handrail is 17.3 feet.

The complete question is-

A spiral staircase turns 270° as it rises 10 feet. The radius of the staircase is 3 feet. What is the number of feet in the length of the handrail?

Answer:

c = 106°

Step-by-step explanation:

The unknown angle and c° form a straight line which is 180°

So, c° + unknown angle = 180°

Remember, the sum of interior angles of a trapezoid is 360°

So, 126° + 108° + 52° + unknown angle = 360°

unknown angle = 360° - 126° + 108° + 52°

unknown angle = 74°

Now, c° + 74° = 180°

c = 180° - 74°

c = 106°

(a) The z-score corresponding to x = 25 is -1. (b)The z-score corresponding to x = 42 is 2.4.(c) The raw score corresponding to z = -3 is 15. (d)  The raw score corresponding to z = 1.5 is 37.5.

For a normal distribution with mean μ = 30 and standard deviation σ = 5:

(a) To find the z-score corresponding to x = 25, we use the formula:

z = (x - μ) / σ

Substituting the values, we get:

z = (25 - 30) / 5 = -1

Therefore, the z-score corresponding to x = 25 is -1.

(b) To find the z-score corresponding to x = 42, we again use the formula:

z = (x - μ) / σ

Substituting the values, we get:

z = (42 - 30) / 5 = 2.4

Therefore, the z-score corresponding to x = 42 is 2.4.

(c) To find the raw score (x) corresponding to z = -3, we use the formula:

z = (x - μ) / σ

Rearranging the formula, we get:

x = μ + zσ

Substituting the values, we get:

x = 30 + (-3) x 5 = 15

Therefore, the raw score corresponding to z = -3 is 15.

(d) To find the raw score (x) corresponding to z = 1.5, we use the same formula:

x = μ + zσ

Substituting the values, we get:

x = 30 + 1.5 x 5 = 37.5

Therefore, the raw score corresponding to z = 1.5 is 37.5.

Step-by-step explanation:

The probability that both professors are chemistry professors is 0.467.

The cost of a Statistics book is a continuous variable because it can take any value within a given range, including decimals, and is not limited to specific, separate values.

For the probability question, there are 10 professors in total (3 statistics + 7 chemistry), and the organization needs 2 advisors. The probability of choosing two chemistry professors can be calculated using the formula: P(Chemistry) = (Number of Chemistry professors) / (Total Number of professors).

First, find the probability of selecting a chemistry professor for the first advisor:
P(First Chemistry) = 7/10.

Next, find the probability of selecting a chemistry professor for the second advisor, considering one chemistry professor has already been selected:
P(Second Chemistry) = 6/9.

Now, multiply both probabilities together to get the probability of selecting two chemistry professors:
P(Both Chemistry) = P(First Chemistry) × P(Second Chemistry) = (7/10) × (6/9) = 0.467.

So, the probability that both professors are chemistry professors is 0.467.

The inverse of the function f(x) = 2x+1 is (x-1)/2.

The output of a function is returned by the inverse function, which also returns the initial value. Consider the inverse relationship between the functions f and g: f(g(x)) = g(f(x)) = x. The initial value is fetched via a function that is its inverse.

Given;

Function, f(x) = 2x + 1.

To find the inverse of the function:

First, let y = f(x)

That is,

y = 2x +1

Then, make x the subject of the equation

y = 2x + 1

To make x the subject of this equation:

First, subtract 1 from both sides

We get

y -1 = 2x

Now, divide both sides by 2.

x = (y-1)/2

Now, rewrite as f⁻¹(x) by replacing y by x.

That is,

f⁻¹(x)  =  (x-1)/2

Therefore, the inverse of the function f(x) is (x-1)/2.

The center of the circle is (3, -2) and the radius is 5.

To find the center and radius of the circle given by the equation x^2 - 6x + y^2 + 4y = 12, we need to complete the square for both the x and y terms.

First, let's complete the square for the x terms:

x^2 - 6x = x^2 - 6x + 9 - 9 = (x - 3)^2 - 9

Next, let's complete the square for the y terms:

y^2 + 4y = y^2 + 4y + 4 - 4 = (y + 2)^2 - 4

Now we can substitute these expressions back into the original equation:

(x - 3)^2 - 9 + (y + 2)^2 - 4 = 12

Simplifying:

(x - 3)^2 + (y + 2)^2 = 25

So the equation is now in standard form, (x - h)^2 + (y - k)^2 = r^2, where the center is (h, k) and the radius is r. Therefore, we can see that the center of the circle is (3, -2) and the radius is sqrt(25) = 5.

Therefore, the center of the circle is (3, -2) and the radius is 5.

Answer:

answer = 1/11

Step-by-step explanation:

The addition rule of probability.

P (T + C) = P(T) + P(C) - P(T ∩ C)

The probability that both these people also used a car given that both of them use a train is 1/11.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

The number of people who used the train and the car.

P (T U C) = 21 - 7 = 14

P(T) = Probability of the number of people who used the train = 12

P(C) = Probability of the number of people who used the car = 6

From the addition rule of probability.

P (T + C) = P(T) + P(C) - P(T ∩ C)

14 = 12 + 6 - P(T ∩ C)

P(T ∩ C) = 12 + 6 - 14 = 18 - 14 = 4

Now,

Two people are chosen.

P(C/T):

= P(T ∩ C) / P(T)

= \(^4C_2\) / \(^{12}C_2\)

= (4 x 3 / 2) / (12 x 11 / 2)

= 6 / 6 x 11

= 1/11

Thus,

The probability that both these people also used a car given that both of them use a train is 1/11.

The sum of interior Angles of Hexagon is always 720°

Any hexagon's internal angles add up to 720° in all cases. By dividing 720° by 6, we may get the size of each interior angle of a regular hexagon. As a result, we have:

720°÷6 = 120°

In a regular hexagon, each inside angle is 120°.

An example of a regular hexagon with equal-length sides and angles is shown in the diagram below. By multiplying the six 120° angles together, we can demonstrate that the result is 720°.

Therefore, the interior angles of a hexagon are always added up to 720°.

The probability of approximately 48% that a player will have a height between 5'2" and 5'6".

To calculate the probability of a player being between 5'2" and 5'6" given that historically, the members of the chess club have had an average height of 5'6" with a standard deviation of 2", we can use the standard normal distribution.

First, we need to convert the heights to z-scores using the formula:

z = (x - μ) / σ

where x is the height we want to find the probability for, μ is the mean height, and σ is the standard deviation.

For 5'2":

z = (62 - 66) / 2 = -2

For 5'6":

z = (66 - 66) / 2 = 0

Next, we can use a standard normal distribution table or calculator to find the area under the curve between these two z-scores.

Using a standard normal distribution table, we can find that the area to the left of z = -2 is 0.0228 and the area to the left of z = 0 is 0.5. Therefore, the area between z = -2 and z = 0 is:

0.5 - 0.0228 = 0.4772

Multiplying this by 100 gives us a probability of approximately 48% that a player will have a height between 5'2" and 5'6".

A survey of car owners to determine the best bus route. Option C is correct.

From the given option, we can see that Option C is the best example of sampling error because there are possibilities that car owners are not familiar with bus routes.

If the polynomial p(x) is divided by (x-1) three times and has a remainder of 1 at the end, then -1 is a double root of p(x). This means that (x+1) is a factor of p(x) raised to the power of 2.

When a polynomial is divided by (x-1), the remainder represents the value of the polynomial at x=1. Since the remainder is 1, it implies that p(1) = 1. Dividing p(x) by (x-1) three times indicates that the polynomial has been factored by (x-1) three times. Consequently, the polynomial can be written as p(x) = (x-1)^3 * q(x) + 1, where q(x) is the quotient obtained after dividing p(x) by (x-1) three times. Since the remainder is 1, it means that when x=1, p(x) leaves a remainder of 1.

Thus, (1-1)^3 * q(1) + 1 = 1, which simplifies to q(1) = 0. This implies that (x-1) is a factor of q(x), meaning that q(x) can be written as q(x) = (x-1) * r(x), where r(x) is another polynomial.

Substituting this into the earlier expression for p(x), we get p(x) = (x-1)^3 * (x-1) * r(x) + 1. Simplifying further, p(x) = (x-1)^4 * r(x) + 1. Now, we can see that p(x) is divisible by (x+1) since (x+1) is a factor of (x-1)^4, and the remainder is 1. Therefore, -1 is a double root of p(x) because (x+1) appears twice in the factored form of p(x).

The square has an area of 1 (since it has sides of length 1).

The circle has a radius of 1/2 and an area of pi/4.

So the ratio of the areas is:

(π/4) / 1 = π/4

Therefore, we would expect:
