Find the slope of the line containing the following two points: (1/10,-3) and (-1/5,-1/5)

Neither statement "E and F are always independent" nor "E and F are always dependent" is correct for mutually exclusive events E and F with positive probabilities p(e)>0 and p(f)>0.

Events that are mutually exclusive cannot occur at the same time. For example, if we have two events E and F such that E represents "rolling a 1 on a fair die" and F represents "rolling a 2 on a fair die", These events cannot occur simultaneously since a 1 and a 2 cannot be rolled.

In probability theory, two events E and F are considered independent if the occurrence of one event has no effect on the probability of the other event occurring. For example, if we have two events E and F such that E represents "rolling a 1 on a fair die" and F represents "rolling a 6 on a fair die", these events are independent because the occurrence of one event (rolling a 1) does not affect the probability of the other event (rolling a 6) occurring.

In the case where events E and F are mutually exclusive, their occurrence does affect each other, as the occurrence of one event makes it impossible for the other event to occur. Therefore, the statement "E and F are always independent" is not correct. Similarly, the statement "E and F are always dependent" is also not correct because dependence is a different concept from mutual exclusiveness.

Therefore, "Neither of the above statements is correct" is the appropriate response.

z is the z-score for the desired confidence level. For 95 percent confidence, z = 1.96 and for 99 percent confidence, z = 2.58.

(a) To calculate the 95 percent and 99 percent confidence intervals for u, we can use the formula:

mean ± z*(standard deviation/sqrt(sample size))

Plugging in the values, we get:

95 percent confidence interval: 5.46 ± 1.96*(2.47/sqrt(100)) = 5.46 ± 0.39

99 percent confidence interval: 5.46 ± 2.58*(2.47/sqrt(100)) = 5.46 ± 0.52

(b) For the 95 percent confidence interval, the interval is 5.46 ± 0.39, which means that we can be 95 percent confident that the true mean waiting time u is between 5.07 and 5.85 minutes. Since 6 minutes falls outside this interval, we cannot be 95 percent confident that u is less than 6 minutes.

(c) For the 99 percent confidence interval, the interval is 5.46 ± 0.52, which means that we can be 99 percent confident that the true mean waiting time u is between 4.94 and 5.98 minutes. Since 6 minutes falls outside this interval, we cannot be 99 percent confident that u is less than 6 minutes.

(d) Based on the results of the 95 percent and 99 percent confidence intervals, we can conclude that there is not enough evidence to be confident that the new mean waiting time is less than six minutes.

The original price of the car is $17420

A percentage is a number or ratio that can be expressed as a fraction of 100.

Given that, a sale price of $13,065, which is 25% less than it sold for when it was new,

We need to find the original price of the vehicle,

Let the original price be x,

x - 25% of x = 13065

x(1-25%) = 13065

x(75/100) = 13065

x = 13065 × 100 / 75

x = 100 × 174.2

x = 17420

A ratio is a comparison of two or more values. It is a way of expressing the relationship between two or more quantities in the form of a fraction. The numerator of the fraction represents the first quantity and the denominator represents the second quantity. The ratio can be written in the form of a:b, where a and b are the two quantities being compared.

For example, if you have 4 apples and 2 bananas, the ratio of apples to bananas can be expressed as 4:2 or 2:1. This means that for every 2 bananas, there are 4 apples. Ratios can also be used to compare values of different units, for example, miles to kilometers or pounds to kilograms.

The two expressions for this situation, with one representing the cost per customer and the other representing the average number of customers are:

Cost: 10 + x

Customer: 16 - 2x

Inequality: 160 - 4x - 2x² ≥ 130.

Based on the information provided, we can logically deduce that the amount of money being charged by Noah per buffet is equal to $10. Also, the total number of customers that chose buffet every hour is equal to 16 customers.

For an increase in the cost of buffet by $1, the average number of customers who selected the buffet would decrease by 2 per hour and the minimum revenue per hour is $130.

Therefore, an expression that represents the cost per customer is given by;

Cost: 10 + x

Additionally, an expression that represents the average number of customers;

Customer: 16 - 2x

Lastly, an inequality that would help Noah make the best pricing decisions is as follows;

Revenue = Cost × Customers
