Answer:80

Step-by-step explanation:

Answer:

(0.5, -0.5)

Step-by-step explanation:

To find the midpoint of A and B, we can use the midpoint formula. The formula involves finding the average of the x-coordinates and the average of the y-coordinates.

Midpoint formula: ((x1 + x2) / 2 , (y1 + y2) / 2)

Using the coordinates of A (-3, -5) and B (4, 4), we can plug them into the formula:

(((-3) + 4) / 2 , ((-5) + 4) / 2)

Simplifying this gives us the midpoint of A and B: (0.5, -0.5).

Therefore, the midpoint of A and B is at coordinates (0.5, -0.5).

Answer:

44

Step-by-step explanation:

there are 792 trees but one acre has 18,

so to find the number of acres divide 792 by 18,

which would give you 44.

According to the given condition, the answer is (b) 44. There are 44 acres in Orangeland.

Expressions can be simple or complex, and can be used in many different contexts depending on the specific programming language or mathematical system being used.

The problem asks us to find the number of acres in Orangeland given the population density of orange trees and the total number of trees. We can use the formula for population density, which relates the number of individuals (in this case, orange trees) to the area they occupy.

The formula for population density is:

Population density = number of individuals/area

We can rearrange this formula to solve for the area:

Area = number of individuals/population density

In this problem, we are given the population density of Orangeland, which is 18 orange trees per acre. We are also given the total number of orange trees, which is 792. To find the area of Orangeland, we can substitute these values into the formula:

Area = 792 / 18

Simplifying this expression, we get:

Area = 44

Therefore, According to the given condition, the answer is (b) 44. There are 44 acres in Orangeland.

Step-by-step explanation:

Answer: [tex]6.75\pi[/tex] inches^2

Step-by-step explanation:

If the diameter is 18 inches, the radius must be 18/2 = 9 inches.

Thus, we can calculate the area using the area of a circle = [tex]\pi r^{2}[/tex].

Plugging in the values, we get the area = [tex]81\pi[/tex] inches^2.

Since 30 degrees is 1/12 of 360 degrees, a 30-degree sector would be equal to 1/12 the area of the circle.

Therefore, we divide [tex]81\pi[/tex]/12 to get the area of the sector = [tex]6.75\pi[/tex] inches^2.

(a) The point estimate is 92/160 = 0.575 or 57.5%.

(b) Using the salt program, the 90% confidence interval is [0.502, 0.648].

(c) Using the salt program, the 95% confidence interval is [0.476, 0.674].

(d) The 95% confidence interval is wider than the 90% confidence interval.

(a) The point estimate for the above problem is the proportion of people who support new gun regulations, which is 92/160 = 0.575 or 57.5%.

(b) To find the 90% confidence interval, we can use the following formula:

[tex]CI = p ± z*(sqrt(p*(1-p)/n))[/tex]

where p is the point estimate, z is the z-score corresponding to the confidence level (90% in this case), and n is the sample size. Using a standard normal distribution table, we find that the z-score for a 90% confidence level is 1.645. Substituting the values, we get:

[tex]CI = 0.575 ± 1.645*(sqrt(0.575*(1-0.575)/160)) = (0.500, 0.650)[/tex]

Therefore, the 90% confidence interval for the proportion of people who support new gun regulations is (0.500, 0.650).

(c) To find the 95% confidence interval, we can use the same formula but with a different z-score. The z-score for a 95% confidence level is 1.96. Substituting the values, we get:

[tex]CI = 0.575 ± 1.96*(sqrt(0.575*(1-0.575)/160)) = (0.480, 0.670)[/tex]

Therefore, the 95% confidence interval for the proportion of people who support new gun regulations is (0.480, 0.670).

(d) The 95% confidence interval is wider than the 90% confidence interval, which is expected because a higher confidence level requires a wider interval to capture the true population proportion with higher probability.

From distance formula, the distance covered by a particle with position (x, y) as time, t is equals to the [tex] 18\sqrt{2}[/tex].

The distance d, traveled by the particle with position vector, r(t) = <x(t), y(t) > over the interval [a,b] is calculated by following

[tex]d = \int_{a}^{b} ( (\frac{dx}{dt})² +(\frac{dy}{dt})² )dt[/tex]. We have a particle with position value (x, y) as t varies in the time interval. The parametric equations are, x = 3 sin² (t), y = 3 cos²(t), on the

time interval [0,3π]. Now the derivative of above parametric equations with respect to time t are [tex]\frac{dx}{dt} = 6 sin(t)cos(t) [/tex] = 3 sin(2t)

[tex]\frac{dy}{dt} = -6 sin(t)cos(t) [/tex]

[tex]= 3\sqrt{2}([ \frac{cos(2t)}{2}]_{0}^{\frac{π}{2}} - [\frac{cos(2t)}{2}]_{\frac{π}{2}}^{π} + [\frac{cos(2t)}{2}]_{π}^{\frac{3π}{2}} - [\frac{cos(2t)}{2}]_{\frac{3π}{2}}^{2π} + [\frac{cos(2t)}{2}]_{2π}^{\frac{5π}{2} }- [ \frac{cos(2t)}{2}]_{\frac{5π}{2}}^{3π})\\ [/tex]

What is distance?

Distance is the total movement of an object, regardless of direction. We can define distance as how much ground an object has covered, regardless of its starting or ending point.

Distance is defined as the size or amount of displacement between two positions. Note that the distance between two locations is not the same as the distance between them. The distance traveled is the total length of the path traveled between two positions.

Here given equation,

d = 16t², where t is the time in seconds and d is the distance in feet and distance is 150 feet.

We want to find the value of t.

Now,

[tex]d = 16 {t}^{2} \\ {t}^{2} = \frac{d}{16} \\ {t}^{2} = \frac{150}{16} \\ t = \sqrt{( \frac{150}{16}) } \\ t = \sqrt{9.375} \\ t = 3.0619[/tex]

It will take Emma about 4.04 years for her balance to reach $450, assuming she doesn't make any payments and the interest rate remains constant.

The formula that models this situation is P(1 + r/n)ⁿˣ, where P is the principal (the initial amount borrowed or invested), r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the time (in years) that the money is invested or borrowed.

In this case, the principal is $300, the annual interest rate is 15%, the interest is compounded monthly (so n = 12), and we want to find the time it takes for the balance to reach $450.

P = 300(1 + 0.15/12)¹²ˣ

To find out how long it will take for Emma's balance to reach $450, we need to solve for t in the equation above. We can do this by using logarithms to isolate the variable t:

=>  log(1.5) = 12t x log(1 + 0.15/12),

we can use the properties of logarithms. Specifically, we can use the property that log(a x b) = log(a) + log(b) to separate the logarithm on the right side of the equation:

log(1.5) = 12t x log(1 + 0.15/12)

log(1.5) = log[(1 + 0.15/12)¹²ˣ]   (using log(a x b) = log(a) + log(b))

Now we have two logarithms that are equal to each other. Therefore, we can take the exponential of both sides to eliminate the logarithms:

1.5 = (1 + 0.15/12)¹²ˣ

Simplifying this expression further, we get:

1.5 = (1.0125)¹²ˣ]

log(1.5) = log[(1.0125)¹²ˣ]]

log(1.5) = 12t x log(1.0125)

Finally, we can solve for t by dividing both sides by 12 x log(1.0125):

log(1.5) / [12 x log(1.0125)] = t

t ≈ 4.04

Therefore, the simplified expression is t ≈ 4.04.

The notation "||v||" typically refers to the Euclidean norm (also known as the magnitude or length) of a vector v in a Euclidean space. The Euclidean norm of a vector v in n-dimensional space is defined as the square root of the sum of the squares of its components:

||v|| = sqrt(v1^2 + v2^2 + ... + vn^2)

Given that ||v|| = 8, we can find the Euclidean norm of -7v as follows:

||-7v|| = 7 * ||-v|| = 7 * sqrt((-v1)^2 + (-v2)^2 + ... + (-vn)^2)

Since -v has the same magnitude as v but points in the opposite direction, we can replace each vi in the above expression with -vi:

||-7v|| = 7 * sqrt((-v1)^2 + (-v2)^2 + ... + (-vn)^2) = 7 * sqrt(v1^2 + v2^2 + ... + vn^2)

But we know that ||v|| = sqrt(v1^2 + v2^2 + ... + vn^2) = 8, so we can substitute:

||-7v|| = 7 * ||v|| = 7 * 8 = 56

Therefore, ||-7v|| is 56.
