4(n+10)=34 what value of N makes the equation true??

Answer:

Let x be the measure of the angle we are trying to find, in degrees.

The complementary angle to x is 90° - x, since the sum of complementary angles is 90 degrees.

The problem tells us that x is 3.4 degrees less than its complementary angle, so we can set up the following equation:

x = (90 - x) - 3.4

Simplifying and solving for x, we get:

x = 86.6/2

x = 43.3

Therefore, the angle we are trying to find has a measure of 43.3 degrees, and its complementary angle has a measure of 90 - 43.3 = 46.7 degrees.

Answer:

y = -3x + 13

Step-by-step explanation:

Assuming the line is linear, you can use the point-slope equation of a line.

(y - y) = m (x - x)

The y and x variables come from the points on the line. Points are written in the form (x, y). In the point (2,7), 2 is x and 7 is y.

1. Plug your points in.

(7 - - 2) = m (2 - 5)

2. Solve for m (the slope)

(7 + 2) = m (2 - 5)

(9) = m (-3)

9 = -3m

m = -3

3. Write an equation of the line with the slope you found.

You can write this equation in different forms, but I'll use the slope-intercept form.

y = mx + b

You'll have to find b, the y-intercept. You can plug one of your points in for x and y as well as your slope, m, and solve for b.

7 = -3(2) + b

7 = -6 + b

b = 13

Therefore, the equation is y = -3x + 13

Answer:

The probability of choosing a heart, P(Heart) = 13/52 = 0.25

Answer:

17.50

Step-by-step explanation:

1: 3.50 dollars

multiply by 5 on eahc side

5 : 17.50

The complete table to make a proportional relationship between weight and price is 17.50.

You start with an equation: 1 * 3.50 dollars

You want to multiply both sides of the equation by 5.

So, you have:

1 * 3.50 dollars = 5 * 3.50 dollars

On the left side, when you multiply 1 by 3.50 dollars, you get 3.50 dollars.

On the right side, when you multiply 5 by 3.50 dollars, you get 17.50 dollars.

So, the result of multiplying both sides by 5 is:

3.50 dollars = 17.50 dollars

This shows that if you have 1 item costing 3.50 dollars and you want to buy 5 of those items, the total cost would be 17.50 dollars.

A complete sufficient statistic (CSS) for the parameter θ is the sample product of Y1, Y2, ..., Yn denoted as Y_prod and the maximum variance unbiased estimator (MVUE) of θ is the sample mean, denoted as Y_bar.

(a) To find a complete sufficient statistic (CSS) for θ, we need to factorize the joint density function into a product of two functions: one depending only on the data and the other depending on the parameter. In this case, the joint density function is given by f(y1, y2, ..., yn) = \(\theta^{n}\) * y1 * y2 * ... * y ×\(n^{\theta -1}\)).

By factoring the joint density function, we can see that it can be expressed as g(y1, y2, ..., yn) × h(y1, y2, ..., yn, θ), where g depends only on the data and h depends on both the data and the parameter.

The function g(y1, y2, ..., yn) = y1 × y2 × ... × y\(n^{\theta -1}\) depends only on the data, while h(y1, y2, ..., yn, θ) = \(\theta^{n}\) depends on both the data and the parameter.

Therefore, the sample product Y_prod = Y1 × Y2 × ... × Yn is a complete sufficient statistic for θ.

(b) The maximum variance unbiased estimator (MVUE) of θ is the sample mean, Y_bar = \(\frac{Y{1} +Y{2} +...+Yn}{n}\). It is an unbiased estimator since E(Y_bar) = θ, and it achieves the minimum possible variance among all unbiased estimators.

To see that Y_bar is the MVUE, we can calculate its variance:

Var(Y_bar) = \(\frac{Var(Y{1} +Y{2} +...+Yn)}{n}\)= (1/\(n^{2}\)) × (Var(Y1) + Var(Y2) + ... + Var(Yn))

Since Y1, Y2, ..., Yn  are identically distributed, Var(Y1) = Var(Y2) = ... = Var(Yn) =\(\frac{\theta}{\theta^{2(\theta+1)} }\). Therefore, Var(Y_bar) = \(\frac{\theta}{n(\theta+1)}\).

It can be shown that among all unbiased estimators, Y_bar achieves the Cramer-Rao lower bound for variance, which means it has the minimum possible variance.

Hence, Y_bar is the MVUE of θ in this case.

If Caroline has 6.8 L of lemonade to serve 20 people. Caroline can pour 340 milliliters of lemonade into each glass.

To find out how many milliliters of lemonade Caroline can pour into each glass, we need to convert the volume of lemonade from liters to milliliters and then divide it equally among the 20 guests.

1 liter is equal to 1000 milliliters. So, Caroline has 6.8 L * 1000 mL/L = 6800 mL of lemonade.

To divide it equally among 20 guests, we divide the total volume of lemonade by the number of guests:

6800 mL / 20 = 340 mL.

The phase diagrams provide a visual representation of the system's behavior by plotting the vector field and trajectories in the x-y plane.

The given system of differential equations is described by:

\(˙x = a - x^2˙y = x - y\)

To find the equilibria, we set ˙x and ˙y equal to zero:

\(a - x^2 = 0 -- > x^2 = a -- > x = ±√ax - y = 0 -- > y = x\)

So, the equilibria are (±√a, ±√a).

Now let's analyze the behavior of the system for different values of 'a'.

For a > 0:

In this case, there are two real equilibria, (√a, √a) and (-√a, -√a). We can observe that (√a, √a) is a stable node, as the eigenvalues of the linearized system around this point have negative real parts. On the other hand, (-√a, -√a) is a saddle point, as the eigenvalues have opposite signs (one positive and one negative).

For a < 0:

In this case, there are no real equilibria since √a and -√a are imaginary. Therefore, the system has no equilibrium points.

To visualize the phase diagrams for a = 1 and a = -1:

For a = 1:

The system has two real equilibria, (1, 1) and (-1, -1). The point (1, 1) is a stable node, and (-1, -1) is a saddle point. The phase diagram would show trajectories converging towards (1, 1).

For a = -1:

Since a < 0, there are no equilibrium points, and thus the phase diagram would show no fixed points or trajectories.

In the question, we are given that the marketing club at the school is opening a student store for which they randomly surveyed 50 students about how much money they spend on lunch each day.

We are asked to find the expected value for a student to spend on lunch each day.

The expected value is the mean of the data where we can show the data as the following table:

x (in $) 10 8   6   5 4 3

f(x)       2  1 12 23 8 4.

The mean of the data can be calculated using the formula, μ = (∑ x f(x))/(∑ f(x)).

Thus, the expected value of the given data can be shown as:

μ = (10*2 + 8*1 + 6*12 + 5*23 + 4*8 + 3*4)/(2 + 1 + 12 + 23 + 8 + 4),

Firstly, we need to know the speed of the object in order to calculate the distance it traveled. If we have the speed, we can use the formula distance = speed x time to find the total distance traveled during the 10.0-second time interval.

Secondly, if we don't have the speed, we can use the equation of motion: distance = (initial velocity x time) + (1/2 x acceleration x time squared). This equation takes into account the initial velocity of the object as well as any acceleration that occurred during the time interval.

Lastly, if we have information about the velocity and acceleration of the object, we can use the kinematic equations to find the distance traveled. These equations relate the velocity, acceleration, time, and distance of an object in motion.
In conclusion, to find the total distance traveled by an object during a 10.0-second time interval, we need to know the speed, initial velocity and acceleration of the object. Once we have this information, we can use the formulas and equations mentioned above to calculate the distance traveled.

Step-by-step explanation:

The answers, rounded to the appropriate number of significant figures, are as follows:

(a) 1.088 ×\(10^2\)

(b) 2.132

(c) 1.3331 ×\(10^1\) and

(d) 1.05.

Let's calculate the answers to the given operations using the appropriate number of significant figures.

(a) 8.370×1.3×10

To perform this multiplication, we multiply the decimal numbers and add the exponents of 10:

8.370 × 1.3 × 10 = 10.881 × 10 = 1.0881 × \(10^2\)

Since the original numbers have four significant figures, we round the final answer to four significant figures:

1.088 × \(10^2\)

(b) 4.265/2.0

For division, we divide the decimal numbers:

4.265 ÷ 2.0 = 2.1325

Since both numbers have four significant figures, the answer should be rounded to four significant figures:

2.132

(c) (1.2588×\(10^3\))×(1.06×\(10^-^2\))

To multiply these numbers, we multiply the decimal numbers and add the exponents:

(1.2588 × \(10^3\)) × (1.06 × \(10^-^2\)) = 1.333128 × \(10^1\)

Since the original numbers have five significant figures, we round the final answer to five significant figures:

1.3331 × \(10^1\)

(d) \((1.11)^(^1^/^2^)\)

To calculate the square root, we raise the number to the power of 1/2:

\((1.11)^(^1^/^2^)\)= 1.0524

Since the original number has three significant figures, the answer should be rounded to three significant figures:

1.05

The missing fraction is 6/12

(you can further simplify this but the question requires that you don't do that)

Step-by-step explanation:

To add fractions easily, their denominators should have the same value, so the denominator should be 12,

Then, to get 16 in the numerator, we need to find a number that on adding to 10, gives 16, or,

10 + x = 16

x = 16 - 10

x = 6

So, the numerator should be 6

so we get the fraction, 6/12

We can also solve it in an alternate way,

\(10/12 + x = 16/12\\x = 16/12 - 10/12\\x = (16-10)/12\\x = 6/12\)

Step-by-step explanation:

a. To find the standard error of the sampling distribution of sample means:

Standard deviation = sqrt(Variance of the population)

Since the population standard deviation is not given, we assume it is 1.

Standard error = (Standard deviation) / sqrt(n)

        = (1) / sqrt(100)

        = 0.01  (rounded to 2 decimal places)

b.

Standard error = 0.01  (from part a)

z = (4.7 - mean) / 0.01

        = (4.7 - 5) / 0.01

        = -0.3  (rounded to 2 decimal places)

Chance that sample mean is between 4.7 and 5.9 hours

        = P(z > -0.3) + P(z < 0.3)

        = 0.762 + 0.761

        = 0.7524  (rounded to 4 decimal places)

c.

Standard error = 0.01  (from part a)

z = (5.1 - mean) / 0.01

        = 0.1  (rounded to 2 decimal places)

Chance that sample mean is between 5.1 and 5.5 hours

        = P(z > 0.1) + P(z < -0.1)

        = 0.4583 + 0.4603

        = 0.4593  (rounded to 4 decimal places)

d.

Standard error = 0.01  (from part a)

z = (7.60 - mean) / 0.01

        = 3  (rounded to 2 decimal places)

Chance that sample mean is greater than 7.60 hours

        = P(z > 3)

        = 0  (rounded to 4 decimal places)

This would be very unlikely.
