Answer:

52.2 ≈ x

Step-by-step explanation:

What we know:

-we see a right triangle

-we have one angle 75°

-we have one side 14

What we need to find:

-we need to find side x rounded to the nearest tenth

Solution:

tan α = opposite side to the angle α / adjacent side to the angle α

tan 75 = x / 14 , multiply both sides by 14

14 · tan 75 = x , use the calculator to multiply (make sure is set in degrees)

52.24871131 = x , round to the nearest tenth

52.2 ≈ x

Answer:

$100.7

60.2 + 40.5 = 100.7

Answer:

$100.70

Step-by-step explanation:

x=8.60(7)+8.10(5)

x=100.7

Here's a possible implementation of the DivideByThree function in C:

int DivideByThree(int number) {

   int count = 0;

   while (number > 0) {

       if (number % 10 == 3) {

           count++;

       }

       number /= 10;

   }

   return count;

}

This function takes an integer number as input and returns the quotient of the division by 3 by counting how many times the number 3 appears in the original number. The function works as follows:

Initialize a counter variable count to 0.

While number is greater than 0, do the following:

a. If the last digit of number is 3 (i.e., number % 10 == 3), increment count.

b. Divide number by 10 to remove the last digit.

Return the final value of count.

For example, if we call DivideByThree(123456333), the function will count three occurrences of the digit 3 in the input number and return the value 1. If we call DivideByThree(33333), the function will count five occurrences of the digit 3 and return the value 1. If there are no occurrences of the digit 3 in the input number, the function will return 0.

The length of the pendulum is approximately 24.99 cm.

The formula for the period of a pendulum is:

T = 2π√(L/g)

where T is the period in seconds, L is the length of the pendulum in meters, and g is the acceleration due to gravity (approximately 9.81 \(m/s^2\)).

To find the length L of the pendulum in centimeters, we can rearrange the formula as follows:

L = (T/2π\()^2\) * g

Substituting T = 0.537 s and g = 9.81 m/s^2 (which is equivalent to 981 cm/s^2), we get:

L = (0.537/(2π)\()^2\) * 981

L ≈ 24.99 cm

Therefore, the length of the pendulum is approximately 24.99 cm.

For the population variance the confidence interval of 95% with standard deviation s = 17 is equal to (176.22, 559.35).

Sample standard deviation s = 17

sample size 'n' = 25

population variance=  o2

To construct a confidence interval for the population variance,

Use the chi-square distribution,

The formula for the confidence interval is,

((n-1) × s^2)/chi2(a/2, n-1) ≤ o^2 ≤ ((n-1) × s^2)/chi2(1-a/2, n-1)

where chi-square(a/2, n-1) and chi-square(1-a/2, n-1) are the chi-square values for the given significance level a and degrees of freedom (n-1).

Substituting the given values, we get,

((25-1) × 17^2)/chi2(0.025, 24) ≤ o^2 ≤ ((25-1) × 17^2)/chi2(0.975, 24)

Calculating the chi-square values using a chi-square distribution attached table ,we get,

((24) × 17^2)/39.36 ≤ o^2 ≤ ((24) ×17^2)/12.40

Simplifying the expressions, we get,

176.22  ≤ o^2 ≤ 559.35

Therefore, the 95% confidence interval for the population variance is (176.22, 559.35).

Answer:

d = \(\frac{2y}{6h}\)

Step-by-step explanation:

Given

6dh = 2y ( isolate d by dividing both sides by 6h )

d = \(\frac{2y}{6h}\)

The value of d from the given equation is d=y/3h.

The given equation is 6dh = 2y.

We need to solve the given equation in terms of d.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, 6dh = 2y can be solved for d as follows:

d=2y/6h

⇒d=y/3h

Therefore, the value of d from the given equation is d=y/3h.

Probability of none of them say they will vote for Trudeau = 0.0123.

To answer this question, we need to first calculate the probability of an individual not voting for Trudeau. Since the probability of someone voting for Trudeau is 31.01%, the probability of someone not voting for Trudeau would be:

1 - 0.3101 = 0.6899

We can use this probability to find the probability that none of the 4 individuals we ask will say they will vote for Trudeau. This is a binomial probability problem where the number of trials is 4, the probability of success (not voting for Trudeau) is 0.6899, and we want to find the probability of 4 failures (none of the 4 individuals say they will vote for Trudeau).

We can use the binomial probability formula:

P(X=k) = (n choose k) * \(p^k * (1-p)^{(n-k)}\)

Where P(X=k) is the probability of k successes in n trials, (n choose k) is the binomial coefficient, p is the probability of success, and (1-p) is the probability of failure. In this case, k=0 (4 failures), n=4, p=0.6899, and (1-p)=0.3101.

P(X=0) = (4 choose 0) * 0.6899^0 * 0.3101^4

P(X=0) = 0.0123 (rounded to 4 decimal places)

Therefore, the probability, after asking 4 individuals, that none of them say they will vote for Trudeau is 0.0123.

To evaluate the integral ∫[-2,2] \((x+3)^4 - x^2 dx\), we can break it down into two separate integrals: ∫[-2,2] \((x+3)^4 dx\)and ∫[-2,2] \(x^2\) dx. By applying the power rule and integrating each term separately, we can find the values of these integrals and then subtract them to obtain the final result.

To evaluate the integral ∫[-2,2] \((x+3)^4 - x^2\) dx, we split it into two separate integrals: ∫[-2,2] \((x+3)^4 dx\) and ∫[-2,2]\(x^2\) dx.

For the first integral, we can expand (x+3)^4 using the binomial theorem or by using the power rule repeatedly. We integrate each term of the expanded expression, and evaluate the integral over the given limits of integration [-2,2].

For the second integral, we apply the power rule directly to integrate\(x^2.\)Again, we evaluate this integral over the limits of integration [-2,2].

After finding the values of both integrals, we subtract the result of the second integral from the result of the first integral to obtain the value of the original integral ∫[-2,2] \((x+3)^4 - x^2 dx.\)

The length of diagonal of the checkerboard is \(40\sqrt{2} cm\).

The Pythagoras theorem can be applied to a right angle triangle. It states that the square of hypotenuse is equal to sum of square length of base and height of the triangle. Mathematically: Hypotenuse² = Perpendicular² + Base². The diagonal of a square divides the square in two right triangles.

The each side of a checkerboard measures 40 cm, that means checkerboard is a square. So, applying the Pythagoras theorem in the triangle formed by diagonal and two sides of square,

\(D^2=S^2+S^2\\D^2=40^2+40^2\\D=40\sqrt{2} cm\)

Where D is the length of diagonal and S is the length of side of checkerboard.

Therefore, the length of the diagonal of checkerboard is \(40\sqrt{2} cm\).

The first step to conducting a statistical study is to clearly define the research question or problem.

This involves identifying the population of interest, the variables to be measured, and the hypothesis or objective of the study. Once the research question is clearly defined, the next step is to design the study, including selecting an appropriate sample size, choosing a sampling method, and determining the data collection method.

It is also important to consider potential sources of bias and confounding factors that may impact the study results. Overall, a well-designed statistical study should be able to produce reliable and accurate results that can be used to draw meaningful conclusions about the population of interest.
