What function does this graph represent?

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.

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

Answer:

one apple: 75 cents

one orange: 60 cents

Step-by-step explanation:

let x be price of one apple

let y be price of one orange

3x + 4y = 4.65

5x + 8y = 8.55

we can do elimination, substitution, or graphing.

this is elimination: (we're eliminating the x in this case to find y, and then use y to find x)

ORIGINAL EQUATIONS: (we're multiplying by 5 so we can eliminate x)

3x + 4y = 4.65

5x + 8y = 8.55

5(3x + 4y = 4.65) = 15x + 20y = 23.25

3(5x + 8y) = 8.55 = 15x + 24y = 25.65

(distribute, and then subtract to get one equation and eliminate x)

  15x + 20y = 23.25

-  15x + 24y = 25.65

------------------------------

  0    -    4y = - 2.4

so we got that, now we make it this:    -4y = -2.4

divide both sides by -4.

-4y = -2.4

-----    -----

-4          -4

y (orange variable) = 0.60

therefore, one orange cost 60 cents.

plug y (the 60 cents) back into one of the original equations (either works) and solve for x.

3x + 4y = 4.65

5x + 8y = 8.55

let's use this equation:  5x + 8y = 8.55

5x + 8(0.6) = 8.55

5x + 4.8 = 8.55

     -4.8      -4.8

5x = 3.75

----    ------

5        5

x = 0.75

therefore, one apple cost 75 cents.

(also, there was an easier number to multiple the equations by)

3x + 4y = 4.65

5x + 8y = 8.55

We could have multiplied (3x + 4y = 4.65) with 2, distributing and bringing it to 6x + 8y = 9.30

Then subtract 6x + 8y = 9.30 from 5x + 8y = 8.55, and you would have solved and gotten x just fine, then plugged x back in to find y)

sorry this answer is so long...good luck :))

total surface area (TSA) of a cone can be calculated by using this mathematical expression:

Total surface area (TSA) of a cone = πr(l + r)

Total surface area (TSA) of a cone = πr(l + r)

Total surface area (TSA) of a cone = 3.142 × 6 × (33 + 6)

Answer:

1440 ft²

Step-by-step explanation:

The roof is made up of 4 congruent triangles.

We first solve for the area of one of the triangles using the formula:

A = (1/2) · b · h

↓ plugging in given values

A = (1/2) · 40 ft · 18 ft

A = 20 ft · 18 ft

A = 360 ft²

Now, we can solve for the surface area of the entire roof by multiplying the area of one of the triangles by 4 (because there are 4 congruent triangles).

SA = 360 ft² · 4 = 1440 ft²

—

Note that we can solve for the area of the triangles using the formula {A = (1/2) · b · h} because the slant height of a pyramid is perpendicular to the side of the pyramid's base that it connects to, thereby making it the height of the triangle that is the pyramid's side.

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.

he volume of the drum can be calculated as follows:

Volume of drum = πr²h

= π(4.2m)²(3.5m)

≈ 246.33 m³

To find out how many full bags of wheat can be emptied into the drum, we need to divide the volume of the drum by the volume of one wheat bag:

Number of full bags of wheat = Volume of drum ÷ Volume of one bag

= 246.33 m³ ÷ 5.39 m³

≈ 45.72

Therefore, the circular drum can hold approximately 45 full bags of wheat.

Answer: 45 Full of bags.

Step-by-step explanation:

The volume of the drum can be calculated using the formula for the volume of a cylinder: V = πr^2h, where r is the radius and h is the height.

V = π(4.2m)^2(3.5m)

V ≈ 246.73 m³

To find out how many bags of wheat can be emptied into the drum, we need to divide the volume of the drum by the space required for one bag:

246.73 m³ ÷ 5.39 m³/bag ≈ 45.81 bags

Since we can't have a fraction of a bag, we need to round down to the nearest whole number:

Number of bags = 45

Therefore, 45 full bags of wheat can be emptied into the drum.

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  = 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.
