Local authority A has made a study of material being recycled per household following the introduction of a recycling scheme. Information from other local authorities that have introduced similar recycling schemes is that recycling material collected each week per household follows a normal distribution with mean 40kg and standard deviation of 15kg and is independent over households. It is considered reasonable to assume that the information from the other local authorities is applicable to local authority A.a. For a randomly selected household whose recycled material is collected by local authority A calculate the probability that the recycled material collected in a given week is less than 30kg. [4]b. A random sample of 100 households is taken and the sample mean recycled material collected per household is found. Calculate the probability that the sample mean recycled material collected in a given week is less than 30kg. [7]c. The sample mean recycled material of 100 households on a single street is taken and found to be 30kg. Why is this not necessarily overwhelming evidence that the recycling scheme of local authority A is not working as well as for other local authorities?d. To encourage increased recycling performance, local authority A introduces an extensive advertising campaign. Following the campaign, the authority collect a random sample of 1,000 households and find the sample mean recycled material is 41kg. Construct a 95% confidence interval for the mean amount of recycled material per household in local authority A, treating population standard deviation as known as 15kg. Is there statistically significant evidence of increased recycling following the campaign?
Answers
The standard deviation is a useful tool in understanding the spread of data and making inferences about the population mean based on sample means.
The standard deviation is a measure of how spread out the data is from the mean.
In this case, the mean recycled material collected per household in other local authorities is 40kg with a standard deviation of 15kg.
In part a, the probability of a randomly selected household recycling less than 30kg in a given week is calculated. In part b, the probability of the sample mean recycled material collected in a given week being less than 30kg for a sample of 100 households is calculated.
In part c, it is explained that finding a sample mean of 30kg for 100 households on a single street does not necessarily mean that the recycling scheme of local authority A is not working.
Finally, in part d, a 95% confidence interval for the mean amount of recycled material per household in local authority A is constructed after an advertising campaign.

The area of square abcd is be parallel lines passing through $a$, $b$, $c$, respectively is the 433.
Squares are quadrilaterals with four congruent aspects and four proper angles, and additionally they have units of parallel aspects. Parallelograms are quadrilaterals with units of parallel aspects. Since squares have to be quadrilaterals with units of parallel aspects, then all squares are parallelograms.
Here we have the values the distance between lines a and b is 12, and the distance between lines b and c is 17.
The distance is 12 and 17
x^2 = 12^2 + 17^2 = 144 +289 = 433

the average daily flour consumption of the restaurant is 35 pounds, with a standard deviation of 7 pounds. the average delivery time from the supplier is 3 days, with a standard deviation of 0.5 days. she decides to order 72 pounds at a time.what is the reorder point that enables her to maintain a 95% service level?
Answers
Ginny should reorder when the inventory level reaches 116.515 pounds to maintain a 95% service level
To calculate the reorder point, we need to consider two factors: the lead time (time between ordering and receiving the delivery) and the safety stock (the extra amount of flour kept in case of unexpected demand or delay in delivery).
Using the formula: Reorder point = (Average daily usage x Lead time) + Safety stock, we can calculate the reorder point.
Here, the average daily flour consumption is 35 pounds with a standard deviation of 7 pounds, and the average delivery time from the supplier is 3 days with a standard deviation of 0.5 days. She decides to order 72 pounds at a time.
The lead time is 3 days, and the safety stock can be calculated using the service level and standard deviation of demand during lead time. Assuming a 95% service level, we can use the z-score of 1.645 (from the standard normal distribution table) to calculate the safety stock.
Safety stock = (z-score x Standard deviation of demand during lead time) = (1.645 x 7) = 11.515 pounds
Now, we can calculate the reorder point:
Reorder point = (Average daily usage x Lead time) + Safety stock = (35 x 3) + 11.515 = 116.515 pounds
Therefore, Ginny should reorder when the inventory level reaches 116.515 pounds to maintain a 95% service level. This ensures that she has enough flour to cover her daily usage and also account for any unexpected demand or delivery delays.

Answers
The statistics z is -1.878 and the p value is 0.0302
Given,
Number of random sample selected, n = 6967
Number of surveys returned, x = 1331
Estimated proportion of return rate;
p = 1331/6967 = 0.192
Significance level, ∝ = 0.01
z would represent the statistic
We investigate the assertion that the return rate is less than 20%, and the following hypotheses are tested:
Null hypothesis, p₀ ≥ 0.2
Alternative hypothesis, p₀ < 0.2
The statistics, z = (p - p₀) / √(p₀(1 - p₀)/n)
That is,
z = (0.191 - 0.2) / √(0.2(1 - 0.2)/6967) = -1.878
Using the alternative hypothesis and the following probability, we can now get the p value:
p value = p(z < - 1.878) = 0.0302
We fail to reject the null hypothesis when the p value exceeds the significance level of 0.01 and there is insufficient evidence to support the conclusion that the return rate is less than 20% at 1% of significance.

Area =
2 square cm
Scale drawing
Object
O A. 128 square cm
B. 16 square cm
O C. 256 square cm
OD. 2 square cm
Answers
The area of the real object represented by the scale drawing is 128 square cm. Thus, the correct answer is option A: 128 square cm.
A scale factor of 1:8 means that every measurement on the scale drawing is 1/8th of the corresponding measurement on the real object. Since the scale drawing has an area of 2 square cm, we need to determine the area of the real object.
To find the area of the real object, we can use the relationship between the scale factors of length and area. Since the scale factor is 1:8, the length ratio between the scale drawing and the real object is 1:8. However, the area ratio is squared, so the area ratio between the scale drawing and the real object is (1:8)^2, which simplifies to 1:64.
Since the area of the scale drawing is 2 square cm, we can multiply it by the area ratio (1:64) to find the area of the real object.
2 square cm * 64 = 128 square cm.
Therefore, the area of the real object represented by the scale drawing is 128 square cm. Thus, the correct answer is option A: 128 square cm.

Answers
The total mass of the region E is 32π/15.
We can use a triple integral to find the mass of the region E. The mass density function is given by ƒ(x, y, z) = 16x²z.
We can set up the triple integral as follows:
∫∫∫E ƒ(x, y, z) dV
where E is the region bounded by x² + y² ≤ z ≤ √√√ 2 − x² - y².
To evaluate this integral, we can use cylindrical coordinates, where x = r cos(θ), y = r sin(θ), and z = z. The region E is then defined by 0 ≤ r ≤ √√√ 2, 0 ≤ θ ≤ 2π, and r² ≤ z ≤ √√√ 2 - r².
The integral becomes:
∫0²√√√2 ∫0²π ∫r²√√√2-r² 16(r cos(θ))²z r dz dθ dr
Simplifying this integral:
∫0²√√√2 ∫0²π 16 cos²(θ) ∫r²√√√2-r² z r dz dθ dr
∫0²√√√2 ∫0²π 8 cos²(θ)(2-r²)² dθ dr
∫0²√√√2 8π/3 (8-r⁴) dr
After integrating, we get the total mass of the region E as:
M = 32π/15
Therefore, the total mass of the region E is 32π/15.

A quadrilateral has two angles that measure 121° and 185º. The other two angles are in aratio of 10:17. What are the measures of those two angles?o andSubmitx IX Practice in the app
Answers
Solution
Given that:
The ratio of 10: 17 means
\(\frac{10x}{17x}=\frac{10}{17}\)Since the sum of angles in a quadrilateral is 360
=> 121 + 185 + 10x + 17x = 360
=> 27x = 360 - 121 - 185 = 54
=> x = 54/27 = 2
Therefore, 10×2 = 20, and 17×2 =34
Hence, the measures of those two angles are 20 and 34 degrees.

This can be proven by using the Transitive Property of Congruence, which states that if two shapes are congruent to each other, and a third shape is congruent to one of those two shapes, then it is also congruent to the other.
In other words, if triangle ABC is congruent to triangle DEF, and triangle DEF is congruent to triangle GHI, then triangle ABC is also congruent to triangle GHI. Since we know that ∠bac ≅ ∠bde, and ∠bca ≅ ∠bac (by the Reflexive Property of Congruence), we can conclude that ∠bca ≅ ∠bde.

The approximate length of the actual object is 1465 ft, which is closest to option D.
What is a scale factor?The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).
First, let's convert the length of the model from millimeters to inches:
372.5 mm = 372.5/10 cm = 37.25/2.54 in ≈ 14.65 in
Next, we can use the scale of the model to find the length of the actual object in feet:
0.5 in. = 50 ft.
So, 1 in. = 100 ft.
Therefore, the length of the actual object in feet is:
14.65 in x (100 ft/in) = 1465 ft
Therefore, the closest length is 1467 feet.
