We can find the slope of a line by using
m = (y2-y1)/(x2-x1)
= (3-4)/(5-8)
= -1/-3
=1/3

Answer:
Sample size should be atleast 625
Step-by-step explanation:
Given that the Labor Bureau wants to estimate, at a 90% confidence level, the proportion of all households that receive welfare
Sample proportion = 17.5%
Let n be the sample size
Standard error of sample proportion=
Z critical for 90% = 1.645
Margin of error = 1.645 * std error
Since margin of error<0.025 we have
The sample size that would limit the margin of error to be within 0.025 of the population proportion is approximately 185.
To estimate the sample size needed to limit the margin of error within 0.025, we can use the formula for sample size in proportion estimation. The formula is:
n = (Z^2 * p * (1-p)) / (E^2)
Where:
n = sample size
Z = Z-score corresponding to the desired confidence level
p = preliminary sample proportion
E = margin of error
Given that the confidence level is 90%, the Z-score for a 90% confidence level is approximately 1.645. The preliminary sample proportion is 17.5% (or 0.175) and the margin of error is 0.025.
Substituting these values into the formula:
n = (1.645^2 * 0.175 * (1 - 0.175)) / (0.025^2)
Simplifying the equation:
n = 1.645^2 * 0.175 * 0.825 / 0.025^2
n ≈ 185.16
So, the sample size that would limit the margin of error to be within 0.025 of the population proportion is approximately 185, rounded up to the nearest whole number.

Mike won 46.67% of all of his matches.
A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."
The total number of matches that Mike wrestled is:
Total matches = number of matches won + number of matches lost + number of matches tied
Total matches = 7 + 6 + 2
Total matches = 15
To find the percentage of matches that Mike won, we can use the formula:
Percentage = (Number of matches won / Total number of matches) x 100%
Plugging in the values we know, we get:
Percentage = (7 / 15) x 100%
Percentage = 0.4667 x 100%
Percentage = 46.67%
Therefore, the Percentage = 46.67%.

Answer:
Mike won 46.67% of his matches
Step-by-step explanation:
Mike participated in a total of 7 + 6 + 2 = 15 matches.
The percentage of matches that Mike won can be found by diving the matches he won by the total number of matches and multiplying it by 100 to convert the decimal to a percentage.
(7/15) x 100% ≈ 46.67%
Therefore, Mike won approximately 46.67% of his matches.
