We are given that this triangle is a right triangle, one angle measurement, and one side length. Therefore, to figure out the other side length, we can use a trigonometric function to figure out side x. If we orient the triangle to angle T, then the hypotenuse is the side length measuring 1.8 units and side length x is the opposite (because it is opposite from angle T). This insinuates we use a sine to figure out side length x because sine finds the ratio between the opposite and the hypotenuse:

sin(50 deg) = x/1.8

1.8*sin(50 deg) = x

x is about 1.3788

Answer:

1.379 or 1.4 (to 1dp)

Step-by-step explanation:

For this question we obviously need to use trigonometry. We will use the equation O = S x H, where O is the opposite side, S is sin and H is the hypotenuse.

Let's start by defining some variables:

P0 = 151000      // initial population in 2013

r = 0.05         // constant annual growth rate

t = 7            // number of years from 2013 to 2020

The exponential model for the population can be written as follows:

y = P0 * (1 + r)^t

Substituting in the values we get:

y = 151000 * (1 + 0.05)^7

y ≈ 209749

Therefore, the exponential model that represents the population of the city t years after 2013 is y = 151000 * (1 + 0.05)^t, and the estimated population in 2020 is about 209,749.

Note that the result is an estimation, and can be affected by various factors, such as migration and mortality rates, that are not accounted for in the model.

The events A and B are dependent events. Option C is answer.

The probability of the union of events A and B, denoted as P(AUB), is calculated as the sum of their probabilities minus the probability of their intersection, denoted as P(AB). So, using the given information, we can find:

P(AB) = P(A) + P(B) - P(AUB)

= 0.2 + 0.3 - 0.44

= 0.06

If A and B were independent events, then we would have P(AB) = P(A)P(B), which is not the case here since P(AB) ≠ P(A)P(B). Thus, A and B are dependent events.

To prove that gcd (n,n+2) is either 1 or 2 for any integer n, we can use a proof by contradiction. We can conclude that gcd (n,n+2) is either 1 or 2 for any integer n.

Suppose there exists an integer n such that gcd (n,n+2) is not 1 or 2, and let k be the gcd of n and n+2, where k ≥ 3. Then k is a common divisor of n and n+2, and k is not equal to 1 or 2.

Since k divides both n and n+2, we can write n = ka and n+2 = kb, where a and b are integers. Subtracting these equations gives 2 = kb - ka = k (b-a).

Since k is not equal to 1 or 2, it follows that k must be greater than or equal to 3. Therefore, k cannot divide 2, which implies that k (b-a) ≠ 2. This contradicts our assumption that gcd (n,n+2) is not 1 or 2.

Hence, we can conclude that gcd (n,n+2) is either 1 or 2 for any integer n.

Using the definition of the derivative of a function at a point, we can show that the derivative of a constant function is equal to 0.

To understand why this is the case, recall that the derivative of a function f at a point c is defined as the limit of the difference quotient as h approaches 0:

f'(c) = lim (h -> 0) [f(c + h) - f(c)] / h

Now, let's consider a constant function f(x) = k, where k is some constant. Then, for any value of x, we have f(x) = k.

Using the definition of the derivative, we can find the derivative of f at any point c:

f'(c) = lim (h -> 0) [f(c + h) - f(c)] / h

= lim (h -> 0) [k - k] / h

= lim (h -> 0) 0 / h

= 0

Since f'(c) = 0 for all values of c, we can conclude that the derivative of a constant function is equal to 0.In conclusion, using the definition of the derivative of a function at a point, we can show that the derivative of a constant function is equal to 0. This is because the difference quotient simplifies to 0 for any constant function, regardless of the value of the constant.

The correct statements are:

B. Point A is farther away from point B than point C is.

D. The distance between points A and B is 5 units.

Let's analyze the given statements about points A(-3,3), B(2,3), and C(2,-1):

A. The distance between points A and B is 4 units.

This statement is incorrect. The distance between points A and B can be calculated using the distance formula: [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Distance AB = [tex]\sqrt{(2 - (-3))^2 + (3 - 3)^2} = \sqrt{5^2 + 0^2} = \sqrt{25}[/tex]  = 5 units. Therefore, the distance between points A and B is 5 units, not 4 units.

B. Point A is farther away from point B than point C is.

This statement is correct. By comparing the distances between A and B and A and C, we see that the distance between A and B is 5 units, while the distance between A and C is [tex]\sqrt{(-3 - 2)^2 + (3 - (-1))^2} = \sqrt{25 + 16} = \sqrt{41}[/tex], which is greater than 5 units. Thus, point A is farther away from point B than point C is.

C. Point A and point C are the same distance from point B.

This statement is incorrect. As calculated earlier, the distance between A and B is 5 units, while the distance between C and B is [tex]\sqrt{(2 - 2)^2 + (-1 - 3)^2} = \sqrt{0^2 + 16}= \sqrt{16}[/tex] = 4 units. Hence, point A and point C are not the same distance from point B.

D. The distance between points A and B is 5 units.

This statement is correct, as determined in statement A.

E. Point A is the same distance from the y-axis as point C is.

This statement is incorrect. The distance between A and the y-axis can be calculated as the absolute value of the x-coordinate of point A: |x-coordinate of A| = |-3| = 3 units. On the other hand, the distance between C and the y-axis is the absolute value of the x-coordinate of point C: |x-coordinate of C| = |2| = 2 units. Hence, point A is not the same distance from the y-axis as point C.

Yes. There is not enough evidence to reject the claim that the percentage of men who use exercise to relieve stress is 15%.

To test the claim, we need to use a hypothesis test with the null hypothesis being that the percentage of men who use exercise to relieve stress is 15% and the alternative hypothesis being that it is not 15%. Using the given information, we can calculate the sample proportion to be 0.12. Then, using a normal approximation to the binomial distribution with a standard error of sqrt(0.15*0.85/100) = 0.0387, we can calculate the test statistic to be (0.12 - 0.15)/0.0387 = -0.773.

Using a significance level of 0.10, the critical value for a two-tailed test is ±1.645. Since the test statistic is not less than -1.645 or greater than 1.645, we fail to reject the null hypothesis and conclude that there is not enough evidence to reject the claim that the percentage of men who use exercise to relieve stress is 15%.

The probability that a randomly chosen student is taking tech given that they are taking art is 50%.

To find the probability that a randomly chosen student is taking tech given that they are taking art, we need to use conditional probability. We can use the formula:

P(Tech | Art) = P(Tech and Art) / P(Art)

We know that 62 students are taking both tech and art, so P(Tech and Art) = 62. To find P(Art), we need to subtract the number of students who are only taking tech or only taking art from the total number of students:

P(Art) = (74 - 62) + (112 - 62) + 62 = 124

Therefore, we have:

P(Tech | Art) = 62 / 124 = 0.5

So the probability that a randomly chosen student is taking tech given that they are taking art is 50%.

In summary, we can use conditional probability to find the probability that a randomly chosen student is taking tech given that they are taking art. We need to find the number of students who are taking both tech and art and the total number of students taking art, and then divide the two numbers to get the probability.

The diameter of the sphere with a surface area of 900 square meters is 16.93 meters.

The surface area of a sphere:

A = 4πr²

where,

A = surface area

r = radius of the sphere

In this case, we have the surface area A = 900 square meters.

A = 4πr²

900 = 4πr²

Dividing both sides by 4π:

225 = πr²

Now, we can solve for the radius:

r² = 225/π

Taking the square root of both sides:

r = √(225/π)

Therefore, the diameter D is:

D = 2r = 2√(225/π)

Calculating the value of the diameter:

D ≈ 2√(225/π) ≈ 2√(225/3.1416) ≈ 2√(71.618) ≈ 2 * 8.465 ≈ 16.93 meters

The double integral over a triangular region with vertices (0,0), (1,2), and (0,3) will be evaluated.

To evaluate the double integral over the given triangular region, we need to set up the integral in terms of the appropriate bounds.

Let's denote the double integral as ∬R f(x, y) dA, where R represents the triangular region.

The vertices of the triangle are given as (0, 0), (1, 2), and (0, 3).

To set up the bounds of integration, we can observe that the triangle is bounded by the lines x = 0, x = 1, and the line joining the points (0, 3) and (1, 2).

For the inner integral, the lower limit of integration (y) is given by the line x = 0, and the upper limit is given by the line joining the points (0, 3) and (1, 2).

Therefore, the bounds for the inner integral are y = 0 to y = 3 - x.

For the outer integral, the lower limit of integration (x) is 0, and the upper limit is 1.

We can now set up the double integral as follows:

The value of y is ± (3√6/2) when x =2

To find the value of y when x = 2, we can use the given differential equation and initial condition.

Given: dy/dx = (x³ + 1)/y

Let's solve the differential equation using the separation of variables:

Separating the variables, we have:

y dy = (x³ + 1) dx

Integrating both sides, we get:

∫ y dy = ∫ (x³ + 1) dx

Integrating the left side:

(1/2) y² = (1/4) x⁴ + x + C

Now, using the initial condition y = 2 when x = 1, we can solve for C:

(1/2) (2²) = (1/4) (1)⁴ + 1 + C

2 = 1/4 + 1 + C

2 = 5/4 + C

C = 2 - 5/4

C = 3/4

Substituting the value of C back into the equation:

(1/2) y² = (1/4) x⁴ + x + 3/4

Multiplying both sides by 2 to eliminate the fraction:

y² = (1/2) x⁴ + 2x + 3/2

Now, we can substitute x = 2 into the equation to find y:

y² = (1/2) (2)⁴ + 2(2) + 3/2

y² = 8 + 4 + 3/2

y² = 27/2

The power of the test for this two-sided alternate with p1=0.85 and p2=0.75, and given sample size is dependent on the significance level and effect size.

power of a statistical test is the probability of correctly rejecting the null hypothesis when it is false, and is typically denoted by 1-β, where β is the probability of a Type II error (failing to reject a false null hypothesis).

In this case, we need to determine the power of the test based on the given information. Since the alternative hypothesis is two-sided, we need to consider both tails of the distribution. We can use a standard normal distribution and the Z-test statistic formula to calculate the power.

Using the formula: Z = (p1-p2)/sqrt(p(1-p)/n), where p = (p1+p2)/2, we can calculate the Z-value for the given parameters.

p = (0.85+0.75)/2 = 0.8
Z = (0.85-0.75)/sqrt(0.8*(1-0.8)/n)

Assuming a significance level of 0.05 (α = 0.025 for each tail) and a two-sided test, we can calculate the critical Z-values using a standard normal distribution table.

Z(α/2) = 1.96

To calculate the power, we need to find the probability of rejecting the null hypothesis when the alternative hypothesis is true, which means finding the area under the standard normal curve beyond the critical Z-values.

For a two-sided test, the power is equal to 1 minus the probability of failing to reject the null hypothesis (Type II error). Thus,

Power = 1 - β = 1 - P(Z < -Z(α/2)) + P(Z > Z(α/2))

Substituting the values, we get:

Power = 1 - P(Z < -1.96) + P(Z > 1.96)
Power = 1 - 0.025 + 0.025
Power = 0.95

Therefore, the conclusion is that the power of the test for this two-sided alternate with p1=0.85 and p2=0.75, and given sample size is 0.95, rounded to three decimal places. This indicates a high probability of correctly rejecting the null hypothesis when it is false, which suggests that the test is statistically powerful.
