Hello!
Before you tackle any problems, it's essential to designate which scenario represents event A and which corresponds to event B. I usually follow the order they are presented in the question, so:
A = S<span>tudent participates in student council
B = S</span><span>tudent participates in after school sports
Any problem that mentions "given" in the question will need to refer to </span>P(A | B)<span> = P(</span>A ∩ B)/P(B). P(A | B) essentially represents the "probability of event A, given that event B has occurred." Meanwhile, P(A ∩ B) denotes the likelihood of both A and B taking place, while P(B) signifies just the probability of event B happening. All required information has been provided, so:
P(A | B) = P(A ∩ B)/P(B)
P(A | B) = 11% / 62%
P(A | B) = 0.11 / 0.62
P(A | B) = 0.18
Thus, there is approximately an 18% probability that <span>a student is involved in student council, given participation in after school sports.
I hope this was helpful!:-)</span>
A. True. The presence of a significant outlier greater than the main group increases the mean, whereas a substantial outlier lower than the main group decreases it. B. False. Outliers distort the true mean's value. In cases where a trimmed mean is considered, the resulting mean may be correct. When outliers exist, using the median is advisable; for instance, the sale of expensive properties significantly affects the mean home prices, hence the term "median home price" is preferred. C. False. The standard deviation decreases because it indicates how data is spread. An outlier leads to greater spread, resulting in a higher standard deviation, which diminishes when the outlier is discarded as the data becomes more centralized. D. False. This assertion holds for normally distributed data that conforms to a bell curve and is centered around the mean; skewed distributions do not follow this principle. E. True. When data is described as "skewed to the right," it implies a large outlier extending the right-side tail more than anticipated, pulling the mean higher while leaving the median unchanged, causing the mean to exceed the median. This concept aligns with statement A. In conclusion, the true responses are A and E, therefore there are two correct answers.
The question is incomplete:
The fee for a parking permit consists of a one-time administration charge plus a monthly fee. A permit for 12 months costs $660. A 15-month permit costs $810.
What is the administration charge?
Answer:
$60
Step-by-step explanation:
To find the administration fee, first compute the difference between the two permits and divide by the three-month variation to identify the monthly fee:
$810-$660= 150
$150/3= $50
Next, multiply the monthly fee by 12 to determine the total monthly fee for 12 months, then subtract this from the 12-month permit cost to ascertain the one-time administration fee:
$50*12= $600
$660-$600= $60
This indicates that the administration fee is $60.
Response:
The volume of oil in milliliters is 1,324.5.
Detailed explanation:
Volume of olive oil = 1.4 qt = 1.4 Quarts
And it is known that 1 Liter equals 1.057 Quarts.
1 L = 1.057 Quarts
Hence, 1.4 Quarts converts to:
1 Liter corresponds to 1000 milliliters.
1 L = 1000 mL
Consequently, the volume of oil in milliliters equals 1,324.5.
