The amount of fertilizer needed for the garden is 508600 grams.

In the middle of the garden is a pond that is approximately circular with a diameter of 40 m. Therefore, the fertilizer will not be applied in the pond area.

The villagers will only apply the fertilizer in the garden area. The recommended rate of application of the fertiliser is 25 g/m².

Therefore, let's find the fertilizer required for the garden.

area of the garden to be fertilized = area of trapezium - area of a circle

area of the garden to be fertilized = 1 / 2 (a + b)h - πr²

area of the garden to be fertilized = 1 / 2 (124 + 196)135 - 3.14(20)²

area of the garden to be fertilized = 1 / 2 (320)(135) - 1256

area of the garden to be fertilized = 43200 / 2 - 1256

area of the garden to be fertilized = 21600 - 1256

area of the garden to be fertilized = 20344 m²

Therefore,

1 m² = 25 grams

20344 m² = ?

Hence,

amount of fertiliser needed  = 20344 × 25 = 508600 grams

The value of the test statistic is -1.75.

To test the claim that the percentage of uninsured patients is under the expected percentage of 32%, we can use a one-sample z-test. The null hypothesis is that the true percentage of uninsured patients is equal to 32%, while the alternative hypothesis is that the true percentage is less than 32%.

Using the sample data, we can calculate the sample proportion of uninsured patients as 40/160 = 0.25. We can then calculate the standard error of the sample proportion as sqrt[(0.32 x 0.68)/160] = 0.0385.

The test statistic can be calculated as (0.25 - 0.32)/0.0385 = -1.75.

To find the p-value associated with this test statistic, we can use a standard normal distribution table or a calculator to find the probability of a z-score less than -1.75. The p-value is approximately 0.04.

Since the p-value is less than the typical significance level of 0.05, we reject the null hypothesis and conclude that there is evidence to support the claim that the percentage of uninsured patients is under the expected percentage of 32%.

Therefore, the correct answer is -1.75, which is the calculated value of the test statistic.

Answer:

Answer  = 21 Sacks

Step-by-step explanation:

First, we need to calculate how much flour the baker will use in 20 days:

Amount of flour used per day for 64 loaves = 64 loaves/day x 400 g/loaf = 25,600 g/day

Amount of flour used in 20 days = 25,600 g/day x 20 days = 512,000 g

Next, we need to convert the amount of flour used into kilograms:

512,000 g ÷ 1000 g/kg = 512 kg

Finally, we need to calculate the minimum number of 25 kg sacks the baker should order:

Number of 25 kg sacks = 512 kg ÷ 25 kg/sack ≈ 20.48

Since the baker cannot order a fraction of a sack, he will need to order at least 21 sacks to last him for 20 days.

The probability of at most one accident in the next 2 hours is 82.15%.

Let X be the number of car accidents in the next 2 hours, and Y be the number of motorcycle accidents in the next 2 hours. Both X and Y follow Poisson distributions, with rates of λX = 0.12 = 0.2 and λY = 0.052 = 0.1, respectively.

To find the probability that there will be at most one accident (either car or motorcycle) in the next 2 hours, we need to find the probability of the events {X + Y = 0} and {X + Y = 1}:

P(X + Y ≤ 1) = P(X + Y = 0) + P(X + Y = 1)

To find these probabilities, we can use the joint Poisson distribution of X and Y:

P(X = i, Y = j) = e^-(λX+λY) * (λXᵃ /a!) * (λYᵇ / b!)

where a and b are non-negative integers.

For X + Y = 0, we have:

P(X + Y = 0) = P(X = 0, Y = 0) = e⁻⁽⁰ ²⁺⁰ ¹⁾  * (0.2⁰ / 0!) * (0.1⁰ / 0!) = e⁻⁰ ³ ≈ 0.7412

For X + Y = 1, we have:

P(X + Y = 1) = P(X = 0, Y = 1) + P(X = 1, Y = 0) = e⁻⁽⁰ ²⁺⁰ ¹⁾ * (0.2⁰/ 0!) * (0.1¹/ 1!) + e⁻⁽⁰ ²⁺⁰ ¹⁾  * (0.2¹/ 1!) * (0.1⁰ / 0!) = 20.20.1*e⁻ ⁰ ³ ≈ 0.0803

Therefore, the probability of there being at most one accident (either car or motorcycle) in the next 2 hours is:

P(X + Y ≤ 1) ≈ 0.7412 + 0.0803 ≈ 0.8215

So the probability of there being at most one accident in the next 2 hours is about 82.15%.

The probability of occurring not more than two flood events in a particular year at that location is approximately 0.546.

The given distribution is λxe-λx! where λ is the expected number of flood events in a year. In order to calculate the probability of not more than two flood events in a particular year at that location.

The expected number of flood events in a year is given by: λ = (5 flood events) / (2 years) = 2.5 flood events per year

The given distribution is:λxe-λx! = 2.5xe-2.5x!

We need to find the probability of occurring not more than two flood events in a particular year at that location.

Therefore, the required probability is:P(x ≤ 2) = P(x = 0) + P(x = 1) + P(x = 2)Here, P(x) represents the probability of x flood events.

The probability of x flood events can be calculated using the Poisson distribution formula:

P(x) = λxe-λx!Substitute λ = 2.5 and x = 0 in the above formula to get:P(0) = (2.5)0e-2.5 / 0! = e-2.5 ≈ 0.082Substitute λ = 2.5 and x = 1 in the above formula to get:P(1) = (2.5)1e-2.5 / 1! = 2.5e-2.5 ≈ 0.206Substitute λ = 2.5 and x = 2 in the above formula to get:P(2) = (2.5)2e-2.5 / 2! = 3.125e-2.5 ≈ 0.258Step 5

Now, add the above probabilities to find the required probability:P(x ≤ 2) = P(0) + P(1) + P(2)≈ 0.082 + 0.206 + 0.258 = 0.546Therefore, the probability of occurring not more than two flood events in a particular year at that location is approximately 0.546.

Answer:

4.06 cm^2

Step-by-step explanation:

If you draw a line from the top vertex to intersect the base (which is 5.8 cm) at 90 degrees, the line is called the height. You need to calculate the height to determine the area.

So the triangle's height will divide the triangles into 2 smaller right triangles.

For the left right triangle, 2.5 will be hypotenuse

=> 2.5^2 = (height)^2 + (base1)^2

=> (height)^2 = 6.25 - (base1)^2

For the right right triangle, 4 will be hypotenuse

=> 4^2 = (height)^2 + (base2)^2

=> (height)^2 = 16 - (base2)^2

So

6.25 - (base1)^2 = 16 - (base2)^2

We have base1 + base2 = 5.8 => base1 = 5.8 - base2

Substitute

6.25 - (5.8 - base2)^2 = 16 - (base2)^2

6.25 - (33.64 - 11.6base2 + base2^2 = 16 - base2^2

base2^2 - base2^2 + 11.6base2 = 16 + 33.6 - 6.25

11.6base2 = 43.35

base2 = 43.35/11.6 = 3.74

since (height)^2 = 16 - (base2)^2

(height)^2 = 16 - (3.74)^2

height^2 = 2.0124

height = 1.42

so area = 1/2hb = 1/2(1.4)(5.8) = 4.06 cm^2

Answer:

I believe it's C.

Step-by-step explanation:

The correct equation of p is C. p(x) = x(x - 3)^2(2x + 7)^2. This is because the given polynomial has a zero of multiplicity 2 at x = 3, a zero of multiplicity 1 at x = 0, and a zero of multiplicity 2 at x = -7/2. Therefore, the equation of the polynomial can be written as p(x) = k(x - 3)^2(x)(2x + 7)^2, where k is some constant. Since the leading coefficient of the polynomial is 1, k = 1. Thus, we get the equation p(x) = x(x - 3)^2(2x + 7)^2.

It is option C and not A, B, or D because:

Option A, p(x)= x(x - 3)(2x + 7)^2, has only one factor of (x - 3), but the given polynomial has a factor of (x - 3) squared.

Option B, p(x) x^2(x - 3)(2x + 7), has an extra factor of x^2 that is not present in the given polynomial.

Option D, p(x)= x(x - 3)^2(2x + 7), is very close to the correct answer, but it is missing the factor of (x) that is present in the given polynomial.

Thus, the correct equation of p is C, p(x) = x(x - 3)^2(2x + 7)^2, which includes all the necessary factors and satisfies the given conditions.

Answer:

85.54 cm

Step-by-step explanation:

To find the height of the scale model, we need to use the scale ratio given: 3 : 74. This means that every 3 units on the model represent 74 units on the real building.

First, we need to determine the ratio of the heights. Let x be the height of the scale model. Then:

3 / 74 = x / 21

Solving for x, we get:

x = 21 * 3 / 74

x = 0.8554 m

To convert this to centimeters, we multiply by 100:

x = 85.54 cm

Therefore, the height of the scale model is 85.54 cm to 2 decimal places.

Answer:

a) The circumference of the cylinder can be found using the formula C = 2πr, where r is the radius of the circular base. Rearranging the formula, we get r = C/2π. To find the circumference, we can use the formula for the curved surface area: A = 2πrh, where h is the height of the cylinder. Substituting the given values, we get:

660 = 2πr(10)

r = 33/π

Now we can find the circumference:

C = 2πr = 2π(33/π) = 66

Therefore, the circumference of the cylinder is 66 cm.

b) The radius of the cylinder is given by r = 33/π, which we already found in part a).

c) The area of one circular base can be found using the formula A = πr^2. Substituting the value of r from part b), we get:

A = π(33/π)^2 = 1089/π

Therefore, the area of one circular base is 1089/π cm^2.

d) The surface area of the cylinder consists of the curved surface area and two circular bases. The area of one circular base was found in part c), so we just need to add the curved surface area to twice the area of one circular base:

Surface area = 2A + 2πrh

Substituting the given values, we get:

Surface area = 2(1089/π) + 2π(33/π)(10) = 2187/π + 660

Therefore, the surface area of the cylinder is 2187/π + 660 cm^2.
