To find the third quartile price, we need to arrange the data in ascending order. The third quartile represents the value below which 75% of the data falls.  The 85th percentile price is approximately 1135536.

Arranged data: 148216, 201866, 352428, 481312, 560473, 689607, 747147, 841952, 966673, 1077650, 1116189, 1264235, 1395465

Since there are 13 data points, the third quartile is located at the position (13 + 1) * (3/4) = 10th position.

The third quartile price is the value at the 10th position, which is 1077650.

Therefore, the third quartile price is 1077650.

Using a calculator or software, the standard deviation of the price is approximately 318,986.

Therefore, the standard deviation of the price is approximately 318,986.

To find the 85th percentile price, we need to arrange the data in ascending order. The 85th percentile represents the value below which 85% of the data falls.

Arranged data: 100021, 259112, 317692, 487684, 508883, 699112, 758500, 841302, 945586, 1047047, 1135536, 1235570, 1315132

Since there are 13 data points, the 85th percentile is located at the position (13 + 1) * (85/100) = 11th position.

The 85th percentile price is the value at the 11th position, which is 1135536.

Therefore, the 85th percentile price is 1135536.

The area of the largest circle is 153.86 yard square.

The measurement that is closest to the area of the largest circle can be calculated as follows:

Therefore,

area of the largest circle = πr²

where

Therefore,

radius = 10 + 4 ÷ 2

radius = 14 / 2

radius = 7 yards

Hence,

area of the largest circle = 3.14 × 7²

area of the largest circle = 3.14 ×49

Worker B appears to be more consistent in performance, while Worker B is more efficient from an overall point of view.

To determine who appears to be more consistent in performance, we need to compare the standard deviations of A and B. Both A and B have a standard deviation of 1.5 hours, which means that they have the same level of consistency in their performance.

To determine who is more efficient from an overall point of view, we need to compare the mean times of A and B. Worker B has a mean time of 4 hours, which is less than the mean time of Worker A (5 hours). This means that Worker B is more efficient than Worker A in completing the job from an overall point of view.

The probability that more than 20% of the sample are from poverty households is approximately 0.8365.

What is the probability?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

We can use the normal approximation to the binomial distribution to solve this problem, given that the sample size is relatively large (n=300) and the probability of success (p=0.22) is not too close to 0 or 1.

Let X be the number of children in the sample who live in poverty households. Then X follows a binomial distribution with parameters n=300 and p=0.22.

The mean of X is given by μ = np = 300 x 0.22 = 66, and the standard deviation is σ = sqrt(np(1-p)) = sqrt(300 x 0.22 x 0.78) ≈ 6.23.

We want to find the probability that more than 20% of the sample are from poverty households, which is equivalent to finding P(X > 0.2n) = P(X > 60).

To use the normal approximation, we can standardize X as follows:

Z = (X - μ) / σ

Then, we have:

P(X > 60) = P(Z > (60 - 66) / 6.23) ≈ P(Z > -0.96)

Using a standard normal table or calculator, we can find that the probability of Z being greater than -0.96 is approximately 0.8365.

Therefore, the probability that more than 20% of the sample are from poverty households is approximately 0.8365.

6) 5.25% will be 5.25/100 = 0.0525
0.0525 x $333.75 = $17.5 (rounded)
$333.75 + $17.5= $351.25

7) 15% will be 15/100 = 0.15
0.15 x $16 = $2.4
$16 + $2.4 = $18.4

8) 20% will be 20/100 = 0.2
0.2 x $2800 = $560
Since it is off the original price, this will be subtraction.
$2800 - $560 = $2240 will be the sales price.
----------
8.25% will be 8.25/100 = 0.0825
0.0825 x $2240 = $184.8
$2240 + $184.8 = $2424.8 will be the total price including tax.

a)The x co-ordinates of P and Q satisfy the equation x² + 4x - 5 = 0.

b)The co-ordinates of P and Q are (-5, -1) and Q = (1, 5).

The given equation of the circle is;

x² + y² = 26.

Th circle satisfies the line y = x + 4.

Thus, Put the value of y in the main equation.

x² + (x + 4)² = 26.

Simplify the equation;

x² + x² + 16 + 8x = 26

2x² + 8x - 10  = 0

Divide the equation by 2.

x² + 4x - 5  = 0  

Part a: This shows that x co-ordinates of P and Q satisfy the equation x² + 4x - 5 = 0.

Part b: Now, do the factorization of x² + 4x - 5  = 0.

(x + 5)(x - 1) = 0

x = -5 and 1.

For x = -5; y = -1

Point P = (-5, -1)
