The diameter of a bicycle wheel is 60 centimeters. How far does the wheel travel when it makes 35 revolutions? Give your answer in. meters( Math in focus singapore math course 1 B)
Answer:
The circumference of a circle is given by the formula "C = pi x d" where "d" is the diameter and "pi" is the mathematical constant with an approximate value of 3.14.
In this problem, the diameter of the bicycle wheel is 60 centimeters, so its circumference is:
C = pi x d = 3.14 x 60 = 188.4 centimeters
When the wheel makes one revolution, it travels one circumference distance. Therefore, when the wheel makes 35 revolutions, it will travel:
distance = 35 x circumference = 35 x 188.4 = 6584 centimeters
We can convert centimeters to meters by dividing the distance by 100:
distance = 6584 ÷ 100 = 65.84 meters
Therefore, the wheel travels 65.84 meters when it makes 35 revolutions.
How long would it take for an investment to at least double its original amount at 3.62% compounded semi annually
Therefore, it would take approximately 19.02 years for an investment to at least double its original amount at a semi-annual compound interest rate of 3.62%.
When an investment is made with a certain amount, the compound interest rate is used to calculate the return on investment. In addition, the number of times interest is compounded each year can have an impact on the investment's outcome.
This question asks about how long it would take for an investment to double at a semi-annual compound interest rate of 3.62%.
To solve for how long it would take for an investment to double at a semi-annual compound interest rate of 3.62%, we need to use the formula for the future value of an annuity:
Future value of an annuity = Payment (1 + r/n)^(nt)where:r is the annual interest raten is the number of times interest is compounded per year Payment is the original amount is the number of years
To solve for t, we can rearrange the formula as follows:t = log(Payment/Future value of an annuity) / log(1 + r/n)where log is the natural logarithm.
The future value of the investment is double the original amount, so we can plug in 2 for Future value of an annuity and simplify the formula to get:t = log(2) / log(1 + 0.0362/2)t = 19.02 years

Which statement is true about the points shown below? The distance between them is zero because they have the same y-coordinate. The distance between them can be found by counting from -3 to 7. The distance between them cannot be calculated because the points do not have the same x-coordinate. The distance between them can be found by doubling the distance of either point from the y-axis.
The statement that is true about the points shown below is: "The distance between them is zero because they have the same y-coordinate."
The distance between two points is typically calculated using the distance formula, which involves the difference between their x-coordinates and y-coordinates. However, in this case, the statement specifies that the points have the same y-coordinate.
The y-coordinate represents the vertical position on a graph, while the x-coordinate represents the horizontal position. When two points have the same y-coordinate, it means they lie on the same horizontal line.
Since distance is measured in a straight line, and these points are already on the same horizontal line, their distance from each other is zero. This is because they are effectively occupying the same position along the horizontal axis.
In summary, when two points have the same y-coordinate, their distance from each other is zero. This is because they lie on the same horizontal line and are already as close to each other as possible in the horizontal direction.

Let Xn be a sequence of random variables that converges in distribution to a random variable X. Let Yn be a sequence of random variables with the property that for any finite number c,
Show that for any finite number c,
(This is the type of result used in the discussion of the power properties of the tests described in Section 10.3.2.)
Using the property of \(Y_n\) being a bounded, continuous function of Xn and the fact that Xn converges in distribution to X, it can be shown that P(|Yn| > c) → 0 as n → ∞ for any finite number c.
To prove that for any finite number c,
P(|Yn| > c) → 0
as n → ∞, we can use the fact that Xn converges in distribution to X and the property of Yn mentioned in the problem statement.
Since Xn converges in distribution to X, we know that for any bounded, continuous function g(x),
E[g(Xn)] → E[g(X)] as n → ∞
By the property of Yn, we know that there exists a bounded, continuous function g(x) such that Yn = g(Xn) for all n. Therefore, we can rewrite the expression as:
P(|Yn| > c) = P(|g(Xn)| > c)
By the boundedness of g(x), we know that there exists a constant M such that |g(x)| ≤ M for all x. Therefore,
P(|Yn| > c) = P(|g(Xn)| > c) ≤ P(|Xn| > c/M)
Since Xn converges in distribution to X, we know that
P(|Xn| > c/M) → 0 as n → ∞
Therefore,
P(|Yn| > c) = P(|g(Xn)| > c) ≤ P(|Xn| > c/M) → 0 as n → ∞
This shows that for any finite number c,
P(|Yn| > c) → 0 as n → ∞, as desired.

Answer:
1. The function that gives the lion population size P(t), t years from today is:
P(t) = 325(0.95)^t
2. To find the population in 4 years, we can substitute t=4 in the function:
P(4) = 325(0.95)^4
P(4) = 279.14
So the population will be approximately 279 lions in 4 years.

In a small city, approximately 14% of those eligible are called for jury duty in any one calendar year.

(a) What is the probability that a particular eligible person in this city is selected in both of the next 2 years? (Enter your answer to four decimal places.) (b) What is the probability that a particular eligible person in this city is selected in all three of the next 3 years? (Enter your answer to six decimal places.)
Answer:
a
\(P(E \ n\ Z) = 0.0196\)
b
\(P(E \ n\ Z \ n \ Y) = 0.0027\)
Step-by-step explanation:
From the question we are told that
The probability of that a person is being called for jury duty in any given year is \(P(J) = 0.14\)
Let P(E) be the probability a person being selected in the first year, Let P(Z) be the probability a person being selected in the second year
and Let P(Y) be the probability a person being selected in the third year
Generally the probability that a particular eligible person in this city is selected in both of the next 2 years is mathematically represented as
\(P(E \ n\ Z) = P(E) * P(Z) = P(J)^2\)
=> \(P(E \ n\ Z) = 0.14^2\)
=> \(P(E \ n\ Z) = 0.0196\)
Generally the probability that a particular eligible person in this city is selected in both of the next 3 years is mathematically represented as
\(P(E \ n\ Z \ n \ Y) = P(E) * P(Z) * P(Y) = P(J)^3\)
=> \(P(E \ n\ Z \ n \ Y) = 0.14^3\)
=> \(P(E \ n\ Z \ n \ Y) = 0.0027\)
This multiplication of each probabilities is valid because each probability is independent of one another

8. Write a paragraph proof.
Proof Given: In a plane, a is perpendicular to b, b id perpendicular to c, and c || d.
Prove: a || d
To prove that line segment a is parallel to line segment d, based on the given information, we can utilize the properties of perpendicular and parallel lines.
Given that a is perpendicular to b and b is perpendicular to c, we know that angles formed between a and b, as well as between b and c, are right angles. Let's denote these angles as ∠1 and ∠2, respectively.
Now, since c is parallel to d, we can conclude that the corresponding angles ∠2 and ∠3, formed between c and d, are congruent.Considering the fact that ∠2 is a right angle, it can be inferred that ∠3 is also a right angle.
By transitivity, if ∠1 is a right angle and ∠3 is a right angle, then ∠1 and ∠3 are congruent.Since corresponding angles are congruent, and ∠1 and ∠3 are congruent, we can deduce that line segment a is parallel to line segment d.
Thus, we have successfully proven that a is parallel to d based on the given information and the properties of perpendicular and parallel lines.

The probability that the forester does not get the seedlings is 1/2 if the mean density of seedlings is 5 per square metre.
What is density?Density means the area within which a substance is collected or taken.
How to calculate the probability?We have been given the mean density =5 square metre.
And we have to calculate the probability that the forester will not get any seedlings.
So the probability that he will get the seedlings will be=5/10

b) Inductive Step
Basis step: Let \(n=2\). Then
\(2! = 2\cdot1 = 2\)
and
\(2^2 = 4\)
so \(2! < 2^2\).
Inductive step: Assume \(k! < k^k\). We want to show that \((k+1)! < (k+1)^{k+1}\).
Now
\((k+1)! = (k+1) \cdot k! \\\\ ~~~~~~~~~~~ < (k+1) \cdot k^k \\\\ ~~~~~~~~~~~ < (k+1) \cdot k^{k+1} \\\\ ~~~~~~~~~~~ < (k+1) \cdot (k+1)^{k+1}\)
where the first inequality follows from the induction hypothesis; the second follows from multiplying the right side by some \(k>2\); and the third from adding the remaining terms to complete the binomial expansion \((k+1)^{k+1}\), all of which are positive since they are some power of \(k>2\).

Find the distance between the points P and Q shown.
The distance between points P and Q is √73
How to find the distance between the two points?First, remember that the distance between two points whose coordinates are (a, b) and (c, d) is given by:
distance = √( (a - c)² + (b - d)²)
Here we can see that the coordinates of the two shown points are:
P = (-3, 2)
Q = (5, -1)
Replacing that in the distance formula we will get:
distance = √( (-3 - 5)² + (2 + 1)²)
distance = √( (-8)² + (3)²)
distance = √73
