Paul's batting scores for cricket in a season are 17, 23, 9, 0, 8, 21 and 12.
Calculate Paul's mean score to the nearest whole number.
Answers
Based on Paul's batting scores for cricket in a season, his mean score to the nearest whole number is equal to 13.
What is a mean?In Mathematics, a mean is sometimes referred to as an average and it can be defined as a ratio of the sum of the total number in a data set (population) to the frequency of the data set.
How to calculate the mean for the set of scores?Mathematically, the mean for this set of scores can be calculated by using the following formula:
Mean = [F(x)]/n
For the total scores, we have;
F(x) = 17 + 23 + 9 + 0 + 8 + 21 + 12
F(x) = 90.
Now, we can determine the mean score as follows;
Mean score = 90/7
Mean score = 12.86 ≈ 13.

Water Usage Up to 6 kl 7 kl - 30 kl 30.1 kl 60 kl More than 60 kl Fixed charge if > 6 kl = R80,70 Free for infrastructure if > = R7,15 Rate per kilolitre (VAT of 15%) inclusive 0 R6,48 R16,20 R21,60 2.4.1. Calculate the cost if Thato uses 35 kl of water charge 2.4.2. Calculate the new fixed charge if it is increased by 15%
Answers
Answer:
The cost for Thato's usage of 35 kl of water is R702.48.
Step-by-step explanation:
Since Thato used 35 kl of water, she falls into the third category where the rate is R16.20 per kl. We can calculate the cost as follows:
Cost = Fixed charge + (Rate per kl × Usage) + Infrastructure fee
The fixed charge is free for infrastructure, so we don't need to include it in this calculation.
Cost = (Rate per kl × Usage) + Infrastructure fee
= (R16.20 × 35) + R7.15
= R567.00 + R7.15
= R574.15
We also need to add 15% VAT to the cost:
Total cost = Cost × (1 + VAT)
= R574.15 × 1.15
= R702.48
Therefore, the cost for Thato's usage of 35 kl of water is R702.48.
2.4.2. Answer: The new fixed charge would be R92.81.
Explanation:
If the fixed charge is increased by 15%, the new fixed charge would be:
New fixed charge = Old fixed charge + (15% of old fixed charge)
= R80.70 + (0.15 × R80.70)
= R80.70 + R12.11
= R92.81
Therefore, the new fixed charge would be R92.81.

Answers
Let 'g' represent the number of granola bars sold by Nozomi. As Nozomi makes $1.25 for each granola bar she sells, and let 'd' represent the amount of money in dollars.
she makes when she sells 'g' granola bars.Therefore, the equation for the above-mentioned relationship is given by:
d = 1.25g Thus, Nozomi makes 1.25 dollars for each granola bar she sells, and for 'g' granola bars sold, she makes an amount of 1.25g dollars. The equation is
8d + 1.25
= 8(1.25g) + 1.25
= 10g + 1.25.
The equation to represent the relationship between the number of granola bars Nozomi sells (g) and the amount of money she makes (d) is:
d = 1.25g + 8
In this equation, "d" represents the amount of money (in dollars) Nozomi makes when she sells "g" granola bars. The term "1.25g" represents the amount of money she makes for each granola bar sold, and the constant term "8" represents any additional amount she makes regardless of the number of granola bars sold.

Answers
The residual for this case is approximately -0.4.
The predicted response for the given case can be obtained by substituting the values of X1, X2, X3, and X4 into the regression equation:
Y = 45.32 - 6.556X1 + 1.697X2 + 1.404X3 + 0.426X4
Substituting X1 = 10, X2 = 8, X3 = 6, and X4 = 48:
Y = 45.32 - 6.556(10) + 1.697(8) + 1.404(6) + 0.426(48)
Y ≈ 24.4
The predicted response for this case is approximately 24.4.
The residual is calculated by subtracting the predicted response from the actual response:
Residual = Actual response - Predicted response
Residual = 24 - 24.4
Residual ≈ -0.4

assume that the amount of time a person experiences cold virus symptoms are normally distributed with a mean of 7.5 days and a standard deviation of 1.5 days. what cold length (number of days of symptoms) is exceeded by only 20% of cold sufferers?
Answers
Answer: The cold length exceeded by only 20% of cold sufferers is approximately 8.76 days.
Step-by-step explanation:
We need to find the value of the cold length (number of days of symptoms) that is exceeded by only 20% of cold sufferers, which corresponds to the 80th percentile of the normal distribution with a mean of 7.5 days and a standard deviation of 1.5 days.
Using a standard normal table or calculator, we can find the z-score that corresponds to the 80th percentile:
z = invNorm(0.8) = 0.8416
We can then use the formula for z-score:
z = (x - μ) / σ
where x is the cold length, μ is the mean, and σ is the standard deviation.
Substituting the given values, we get:
0.8416 = (x - 7.5) / 1.5
Solving for x, we get:
x - 7.5 = 0.8416 * 1.5
x - 7.5 = 1.2624
x = 8.7624
Therefore, the cold length exceeded by only 20% of cold sufferers is approximately 8.76 days.

1+root2/(3-root2)^2 can be writen in the form a+b root2
find the values of a and the value of b
Answers
Answer:
We can start by multiplying the denominator by its conjugate:
(3 - root2)^2 = (3 - root2)(3 + root2) = 9 - 2*root2^2 = 9 - 2 = 7
Now, we can divide the numerator by the denominator:
1+root2/(3-root2)^2 = (1+root2)/7
To get the expression in the form a + b*root2, we can see that a = 1/7 and b = 1/7 *root2
So the final form of the expression is:
1/7 + 1/7 *root2
a = 1/7 and b = 1/7 *root2

Earnings per share, EPS is calculated using the formula \large EPS=\frac{NI-PD}{SO}, where NI is net income, PD is preferred dividence, and SO number of outstanding shares.
What is a company's net income if they have $50,000 in preferred dividends and pay out $0.55 per share on 200,000 shares?
Answers
Answer: $160,000
Step-by-step explanation:
Given the following :
Earning per share (EPS) = $0.55
Number of outstanding shares = 200,000
Preferred dividend = $50,000
EPS = (NET INCOME - PREFERRED DIVIDEND) / NUMBR OF OUTSTANDING SHARES
0.55 = ( NET INCOME - 50000) / 200000
200000 × 0.55 = NET INCOME - 50000
110,000 = NET INCOME - 50000
NET INCOME = 110,000 + 50,000
NET INCOME = $160,000

b. samples are more trustworthy.
c. populations are often too large to test.
d. samples are more meaningful and interesting
Answers
Social scientists gather data from samples instead of populations because c. populations are often too large to test.
Social scientists often cannot test an entire population due to its size, so they gather data from a smaller group or sample that is representative of the larger population. This allows them to make inferences about the larger population based on the data collected from the sample. The sample size must be large enough to accurately represent the population, but it is not necessarily larger or more complete than the population itself. Trustworthiness, meaning, and interest are subjective and do not necessarily determine why social scientists choose to gather data from samples.

Suppose there are two producers in a market with the following supply functions. Supply 1: P=6+0.7Q Supply 2:P=16+0.6Q When the price is [Answer], the total quantity supplied is 250. (In decimal numbers, with two decimal places, please.) Answer:
Answers
The price at which the total quantity supplied is 250 is $11.58.
In order to find the price at which the total quantity supplied is 250, we need to equate the total quantity supplied by both producers (Supply 1 and Supply 2) and solve for the price.
Supply 1: P = 6 + 0.7Q
Supply 2: P = 16 + 0.6Q
To find the equilibrium price, we set the total quantity supplied equal to 250:
0.7Q + 0.6Q = 250
1.3Q = 250
Q = 250 / 1.3 ≈ 192.31
Now that we have the quantity, we can substitute it back into either supply function to find the price. Let's use Supply 1:
P = 6 + 0.7Q
P = 6 + 0.7 * 192.31
P ≈ 6 + 134.62
P ≈ 140.62
Therefore, the price at which the total quantity supplied is 250 is approximately $11.58.
