The sample size required to estimate the mean weight of all female white-tailed deer with a 90% confidence level within 5 pounds of the actual weight is 43.

In order to estimate the sample size required to estimate the mean weight of all female white-tailed deer with a 90% confidence level within 5 pounds of the actual weight, the following steps are to be followed:

Step 1: Determine the confidence level and the maximum allowable error

The given confidence level is 90%.

The maximum allowable error is 5 pounds.

Step 2: Determine the population standard deviationThe population standard deviation is given as σ = 18 pounds.

Step 3: Determine the critical value

The critical value corresponding to a 90% confidence level is 1.645.

Step 4: Calculate the sample size formula to calculate the sample size is given as

n = [(z-value)² × σ²] / E² Where n = sample size

z-value = critical value

σ = population standard deviation = maximum allowable error

Substituting the given values in the above formula, we get,n = [(1.645)² × (18)²] / (5)²= 42.68≈43 (approx)

Therefore, the sample size required to estimate the mean weight of all female white-tailed deer with a 90% confidence level within 5 pounds of the actual weight is 43. Answer: 43

The simplified expression is 4x - 23.

Option A is the correct answer.

We have,

To simplify the expression 3(2x - 5) - 2(x + 4), we need to apply the distributive property and combine like terms.

First, distribute the 3 to the terms inside the parentheses:

3 * 2x = 6x

3 * (-5) = -15

Next, distribute the -2 to the terms inside the parentheses:

-2 * x = -2x

-2 * 4 = -8

Now, let's simplify the expression by combining like terms:

6x - 15 - 2x - 8

Combine the x terms: 6x - 2x = 4x

Combine the constant terms: -15 - 8 = -23

Thus,

The Laplace transformation in the given function is = 5 - 8e⁻⁷ˣ/ x

Rewrite f in terms of the unit step function:

f(t) = { y = 5 for 0 ≤ t ≤ 7

    = { x = - 3 t > 7

f(t) = 5{u(t) -u(t -7) - 3u (t -7)}

     = 5u(t) - 8u (t-7)

Recall the time-shifting property of the Laplace transform:

L I u(t - c)f(t -c) I

= e⁻ᵃˣ L[f(t)]

and the Laplace transform of a constant function,

L(K) = k/a

So we have

L{f(t)} = 5u(t) - 8u (t-7)

       = 5 L[1] - 8e⁻⁷ˣ

       = 5 - 8e⁻⁷ˣ/ x

The probabilities of:

A: Getting a number less than 4 on the dice is 1/2

B: Getting tails (T) on the coin is 1/2

In the experiment of throwing a die and flipping a coin, let's define the following events:

A: Getting a number less than 4 on the dice (possible outcomes: 1, 2, 3).

B: Getting tails (T) on the coin.

To determine the probabilities of these events, we need to consider the number of favorable outcomes and the total number of possible outcomes.

For event A:

Number of favorable outcomes: 3 (numbers 1, 2, 3)

Total number of possible outcomes on the dice: 6 (numbers 1 to 6)

So, P(A) = favorable outcomes / total outcomes = 3/6 = 1/2

For event B:

Number of favorable outcomes: 1 (tails T)

Total number of possible outcomes on the coin: 2 (heads H, tails T)

So, P(B) = favorable outcomes / total outcomes = 1/2

Answer:

who mows the lawn for 7 dollars :/

Step-by-step explanation:

the given differential equation dR/dx = a(R² + 16), where a is a non-zero constant, is R = -4/√[tex](16 - e^(2ax + C))[/tex], where C is the constant of integration.

In the first part, the solution to the differential equation is R = -4/√[tex](16 - e^(2ax + C)).[/tex]

In the second part, let's solve the differential equation step by step. We start by separating variables:

dR/(R² + 16) = a dx.

Next, we integrate both sides:

∫(1/(R² + 16)) dR = ∫a dx.

To integrate the left side, we can use a substitution. Let u = R² + 16, then du = 2R dR. This gives us:

(1/2) ∫(1/u) du = ∫a dx.

Simplifying the left side and integrating, we have:

(1/2) ln|u| = ax + C.

Substituting back for u and rearranging, we get:

ln|R² + 16| = 2ax + 2C.

Taking the exponential of both sides, we have:

|R² + 16| = [tex]e^(2ax + 2C).[/tex]

Considering the absolute value, we can rewrite it as:

R² + 16 = [tex]e^(2ax + 2C).[/tex]

Solving for R, we get:

R = ±√(e^(2ax + 2C) - 16).

Simplifying further:

R = ±√(e^(2ax + C) - 16).

Finally, we can rewrite it as:

R = -4/√(16 - e^(2ax + C)).

The equation for the parabola that passes through the points (-1,0), (1,6), and (-3,-14) is y = -2x² + 3x + 1.

To find the equation of a parabola, we need to substitute the given points into the general form of the equation, y = az² + bz + c, and solve for the unknown constants a, b, and c. In this case, we have three points: (-1,0), (1,6), and (-3,-14). We can plug in the x and y values of each point into the equation to obtain three equations.

For the point (-1,0):

0 = a(-1)² + b(-1) + c

For the point (1,6):

6 = a(1)² + b(1) + c

For the point (-3,-14):

-14 = a(-3)² + b(-3) + c

Now we have a system of three equations with three unknowns (a, b, and c). Solving this system will give us the values of a, b, and c, which we can then substitute back into the general equation to obtain the specific equation of the parabola.

To solve the system, we can use various methods such as substitution, elimination, or matrices. However, to keep the explanation concise, I'll provide the solution directly.

Solving the system of equations, we find:

Substituting these values back into the general equation, we get:

y = -2x² + 3x + 1

Based on the given statistics, we will shape each correlation to the corresponding scatterplot as follows:

13.True or False: r = 0.49 → (2)

14.True or False: r = -0.48 → (4)

15.True or False: r = -0.03 → (3)

16.True or False: r = -0.85 → (1)

Based on the given records, we need to match each correlation fee to the corresponding scatterplot. Let's analyze every correlation and its corresponding scatterplot in more detail:

13.True or False: r = 0.49 → (2)

A correlation coefficient of 0.49 shows a tremendous correlation among the variables. This means that as one variable will increase, the alternative variable tends to grow as nicely, albeit not flawlessly. In the scatterplot categorized as (2), we'd assume to look at a trendy upward fashion wherein the factors are quite scattered around the road of satisfactory fit.

14.True or False: r = -0.48 → (2)

A correlation coefficient of -0.48 indicates a bad correlation between the variables. This manner that as one variable increases, the opposite variable has a tendency to lower. In the scatterplot labeled as (2), we'd expect to see a standard downward fashion wherein the points are rather scattered around the line of fine match.

15.True or False: r = -0.03 → (4)

A correlation coefficient of -0.03 shows a very weak terrible correlation between the variables. This method that there is almost no relationship between the variables. In the scatterplot categorized as (four), we would count on seeing factors scattered randomly, with no discernible pattern or fashion.

16. True or False: r = -0.85 → (1)

A correlation coefficient of -0.85 shows a sturdy poor correlation between the variables. This method that as one variable increases, the other variable has a tendency to decrease substantially. In the scatterplot labeled as (1), we might count on to peer a clear downward trend in which the factors are tightly clustered around the road of the first-rate match.

By analyzing the strengths and instructions of the correlations, we can suit each correlation value to its corresponding scatterplot as follows:

13. True or False: r = 0.49 → (2)

14.True or False: r = -0.48 → (2)

15.True or False: r = -0.03 → (4)

16.True or False: r = -0.85 → (1)

Please notice that scatterplots provide visible representations of statistics and relationships between variables, and the interpretations might also vary relying on the context and the statistics being analyzed.

Answer: 1176

Step-by-step explanation: 7 times as big is an ambiguous term; it could mean that each side is 7 times larger, or that the shape as a whole is made 7 times larger. We'll assume that each side is made larger, because that is typically the type of question asked. The area is given as base times height, and obviously, if you dilate the non-base side by 7, the height will also become 7, because those two lines from a triangle with the third side being the base extended. I wish I could draw you a diagram but i can;t. Either way, think of it as a square, and if we dilate each side by 7, then we have lx7xwx7=Area, which is lw*49=49 times the given area, which is 24; 24*49=1176
