The following parts can be solved by the concept of Area.

1. The area of the sprinkled lawn is 9π square feet, where π is approximately 3.14.

2. The area that the storm will affect is 113.1 square miles, where the value of π is approximately 3.14.

1. To find the area of the sprinkled lawn, we need to find the area covered by the sprinkler in one rotation and then multiply it by the number of rotations. The sprinkler sprays water 3 feet in every direction, so it covers a circular area with a radius of 3 feet. The area of a circle with a radius of 3 feet is given by the formula A = πr^2, where r is the radius of the circle.

Therefore, the area covered by the sprinkler in one rotation is 9π square feet (A = π x 3^2 = 9π). If the sprinkler rotates n times, then the total area covered by the sprinkler is n times the area covered in one rotation.

2. To find the area that the storm will affect, we need to find the area of the circle with a radius of 6 miles. The area of a circle is given by the formula A = πr^2, where r is the radius of the circle. Therefore, the area that the storm will affect is 36π square miles (A = π x 6^2 = 36π). To get a numerical value, we can use the approximation of π as 3.14, which gives us an area of approximately 113.1 square miles (A = 3.14 x 36 = 113.1).

Thus, the storm will affect an area of approximately 113.1 square miles.

Step-by-step explanation:

Notice that angle z and the angle with measure 70⁰ is a linear pair. Hence, it follows that they are supplementary (they'll sum up to 180⁰):

Solve for z in the equation:

Using the Angles formed by two intersecting chords theorem: If two chords intersect inside a circle, then the measure of the angle formed is one-half the sum of the measure of the arcs intercepted by the angle and its vertical angle , it follows that:

Substitute z=110⁰ into the equation and solve for w:

The value of w is 141.

Answer:

Bacterial population at the time of 10 hours = 1040000

Step-by-step explanation:

Let the function that defines the bacterial population after 'x' hours is,

p(x) = a(b)ˣ

Where a = Initial population

And 'x' = Duration or time

Since bacterial population is getting doubled every hour,

2a = a(b)¹

b = 2

Therefore, function will be,

p(x) = a(2)ˣ

From the graph attached,

Point (5, 32500) lies on the graph of the function.

32500 = a(2)⁵

a = \(\frac{32500}{32}=1015.625\)

Therefore, the function will be,

p(x) = 1015.625(2)ˣ

For x = 10 hours,

p(10) = 1015.625(2)¹⁰

        = 1040000 bacteria

If there are 2,820 students in his school, then the number of students who own a reptile for a pet is 352.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

Let us consider that Zhan surveyed n students, and x of them own a reptile for a pet.

The following formula to estimate the total number of students who own a reptile for a pet:

Estimated number = (x/n) × total population

We are given the total population of the school, which is 2,820 students.  Let's assume that Zhan surveyed 200 students, and 25 of them own a reptile for a pet.

Lets use the formula to estimate the total number of students who own a reptile for a pet as follows:

Estimated number = (25/200) × 2,820

Estimated number = 352.5

Therefore, we can estimate that  352 students in Zhan's school own a reptile for a pet based on the data from his random sample.

815,000 in 10 years

To find the population of a city after a certain number of years, we can use the following formula:

Population after n years = Population after 0 years × (1 + growth rate)^n

In this case, the population at year 0 (current population) is 500,000, the growth rate is 50/1000 = 0.05 (because the rate is given as 50 per 1000 people), and n is the number of years (10 in this case). Substituting these values ​​into the formula gives:

Population in 10 years = 500,000 × (1 + 0.05)^10 = 500,000 × 1.63 = 815,000

So, if the population of the city continues to grow at a rate of 50 people per 1000 people per year, it will be about 815,000 in 10 years.

The most appropriate blood component for a 9-year-old girl suspected of having idiopathic thrombocytopenic purpura (ITP) would be platelets.

Idiopathic thrombocytopenic purpura (ITP) is a disorder that causes a low platelet count, leading to bleeding and bruising easily. Platelets are the component of blood responsible for clotting, which helps stop bleeding. In ITP, the body's immune system mistakenly attacks and destroys platelets, causing a decrease in their number. If a 9-year-old girl is suspected of having ITP and has bleeding gums, she would likely benefit from a transfusion of platelets. This is because the platelets can help stop the bleeding by forming clots.

Other blood components, such as red blood cells or plasma, would not address the underlying issue of a low platelet count. Platelets can be transfused through a process called a platelet transfusion, in which the donor platelets are separated from the blood and transfused into the recipient's bloodstream. In summary, platelets are the most appropriate blood component for a 9-year-old girl suspected of having ITP with bleeding gums, as they can help stop bleeding by forming clots.

Percentage of data within 2 population standard deviations of the mean is 68%.

To calculate the percentage of data within two population standard deviations of the mean, we need to first find the mean and standard deviation of the data set.

The mean can be found by summing all the values and dividing by the total number of values:

Mean = (20*2 + 22*8 + 28*9 + 34*13 + 38*16 + 39*11 + 41*7 + 48*0)/(2+8+9+13+16+11+7) = 32.68

To calculate standard deviation, we need to calculate the variance first. Variance is the average of the squared differences from the mean.

Variance = [(20-32.68)^2*2 + (22-32.68)^2*8 + (28-32.68)^2*9 + (34-32.68)^2*13 + (38-32.68)^2*16 + (39-32.68)^2*11 + (41-32.68)^2*7]/(2+8+9+13+16+11+7-1) = 139.98

Standard Deviation = sqrt(139.98) = 11.83

Now we can calculate the range within two population standard deviations of the mean. Two population standard deviations of the mean can be found by multiplying the standard deviation by 2.

Range = 2*11.83 = 23.66

The minimum value within two population standard deviations of the mean can be found by subtracting the range from the mean and the maximum value can be found by adding the range to the mean:

Minimum Value = 32.68 - 23.66 = 9.02 Maximum Value = 32.68 + 23.66 = 56.34

Now we can count the number of data points within this range, which are 45 out of 66 data points. To find the percentage, we divide 45 by 66 and multiply by 100:

Percentage of data within 2 population standard deviations of the mean = (45/66)*100 = 68% (rounded to the nearest percent).

Therefore, approximately 68% of the data falls within two population standard deviations of the mean.

(i) The relationship between the OLS estimators of α₂ and ᵝ₂ can be determined by considering the relationship between the consumption function and the savings function. Since X = Y + Z, we can substitute this into the consumption function equation to obtain Y = α₁ + α₂(Y + Z) + e. Simplifying the equation, we get Y = (α₁/(1 - α₂)) + (α₂/(1 - α₂))Z + (e/(1 - α₂)). Comparing this equation with the savings function Z₁ = ᵝ₁ + ᵝ₂X + u₁, we can see that the OLS estimator of ᵝ₂ is related to the OLS estimator of α₂ as follows: ᵝ₂ = α₂/(1 - α₂).

(ii) The residual sum of squares (RSS) will not be the same for the two models of Y₁ = α₁ + α₂X₁ + e and Z₁ = ᵝ₁ + ᵝ₂X₁ + u₁. This is because the error terms e and u₁ are different for the two models. The RSS is calculated as the sum of squared differences between the observed values and the predicted values. Since the error terms e and u₁ are different, the predicted values and the residuals will also be different, resulting in different RSS values for the two models.

(iii) The R² terms of the two models cannot be directly compared. R² is a measure of the proportion of the total variation in the dependent variable that is explained by the independent variables. Since the consumption function and the savings function have different dependent variables (Y and Z, respectively), the R² values calculated for each model represent the goodness of fit for their respective dependent variables. Therefore, the R² terms of the two models cannot be compared directly.

The hypothesis test is right-tailed, and the parameter being tested is the population mean.

In hypothesis testing, the null hypothesis (H₀) represents the claim or assumption to be tested, while the alternative hypothesis (H₁) represents the alternative claim. In this case, the null hypothesis is stated as H₀: μ = 105, where μ represents the population mean.

To determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed, we look at the alternative hypothesis (H₁). If H₁: μ > 105, it indicates a right-tailed test, meaning we are testing whether the population mean is greater than 105.

On the other hand, if H₁: μ < 105, it would be a left-tailed test, testing whether the population mean is less than 105. A two-tailed test, H₁: μ ≠ 105, would be used when we want to test whether the population mean is either significantly greater or significantly less than 105.

In this case, the alternative hypothesis is stated as H₁: μ ≠ 105, which means we are conducting a two-tailed test. However, the question asks specifically whether it is left-tailed, right-tailed, or two-tailed. Since the alternative hypothesis is not strictly greater than or strictly less than, we can consider it as a right-tailed test. Therefore, the hypothesis test is right-tailed.

Furthermore, the parameter being tested in this hypothesis test is the population mean (μ). The test aims to determine whether the population mean is equal to or significantly different from 105.

A. The total differential of the utility function U(X,Y) = X^αY^β is dU = αX^(α-1)Y^β dX + βX^αY^(β-1) dY.

B. The total differential of the utility function U(X, Y) = X^2 + Y^3 + XY is dU = (2X + Y) dX + (3Y^2 + X) dY.

A. The total differential of a function represents the small change in the function caused by infinitesimally small changes in its variables. In this case, we are given the utility function U(X, Y) = X^αY^β, where α and β are constants.

To find the total differential, we differentiate the utility function partially with respect to X and Y, and multiply the derivatives by the differentials dX and dY, respectively.

For the partial derivative with respect to X, we treat Y as a constant and differentiate X^α with respect to X, which gives αX^(α-1). We then multiply it by the differential dX.

Similarly, for the partial derivative with respect to Y, we treat X as a constant and differentiate Y^β with respect to Y, resulting in βY^(β-1). We then multiply it by the differential dY.

Adding these two terms together, we obtain the total differential of the utility function:

dU = αX^(α-1)Y^β dX + βX^αY^(β-1) dY.

This expression represents how a small change in X (dX) and a small change in Y (dY) affect the utility U(X, Y).

B. To find the total differential of the utility function U(X, Y) = X^2 + Y^3 + XY, we differentiate each term of the function with respect to X and Y, and multiply the derivatives by the differentials dX and dY, respectively.

For the first term, X^2, we differentiate it with respect to X, resulting in 2X, which is then multiplied by dX. For the second term, Y^3, we differentiate it with respect to Y, resulting in 3Y^2, which is multiplied by dY. Finally, for the third term, XY, we differentiate it with respect to X and Y separately, resulting in X (multiplied by dY) and Y (multiplied by dX).

Adding these three terms together, we obtain the total differential of the utility function:

dU = (2X + Y) dX + (3Y^2 + X) dY.

This expression represents how a small change in X (dX) and a small change in Y (dY) affect the utility U(X, Y).
