Answer:
4
Step-by-step explanation:
Each sandwich costs 6 dollars, while chips sell for 3 dollars. She purchased 5 sandwiches at 6 dollars each, amounting to 30 dollars (5*6=30). This leaves her with 12 dollars to use since her total expenditure was 42 dollars. Given that chips are 3 dollars each, with 12 dollars left, 4 bags could be bought (4 * 3 = 12).
The highest 5% of scores corresponds to the 95th percentile, meaning the cutoff score

is defined as

When transformed into the standard normal distribution,

A cumulative probability of 95% corresponds to a z-score of approximately

, indicating that the cutoff score is likely around
Answer:
Question 13: For age groups y=1 and y=1.3, the response time is 8 microseconds.
Question 14: The club experienced losses between 11.28 and 4.88 years.
Step-by-step explanation:
Question 13:
The equation that gives the response rate R of 8 microseconds can be expressed as

Upon graphing this, we determine the solutions to be

We consider only positive values of y applicable in real-life scenarios.
Thus, the response is 8 microseconds solely for the age groups y=1 and y=1.3.
Question 14:
The football club incurs losses when 
Or

Graphing this inequality reveals the solutions to be
and 
As only positive values for t are relevant in practical situations, we accept the second solution.
Hence, the club faced losses during the years 
Answer:
Step-by-step explanation:
A survey of 8225 Americans included age data collection.
The mean age was recorded as 42, whereas the median was noted as 37.
This indicates median < mean.
When the mean exceeds the median, it suggests the presence of right skewness in the data.
In a symmetrical distribution, mean and median align. If there is a discrepancy, the distribution is skewed.
Consequently, with the mean > median, the data is skewed to the right.
