The measurement of variability that would be best to use for the distribution is Interquartile Range, the correct option is (b).

The best measurement of variability to use depends on the distribution of the data and the purpose of the analysis.

If the distribution is skewed or contains outliers, the median and interquartile range would be better measures of variability than the mean and standard deviation.

The median is less affected by extreme values, and

The interquartile range is a robust measure of spread that is not influenced by outliers.

The mean and mean absolute deviation may be appropriate if the data are approximately symmetric and do not contain outliers.

Therefore, The best measurement of variability is (b) Interquartile range.

The Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the last event.

a. The probability that none is sold on a particular day can be calculated using the formula:
P(X = 0) = (e^-λ)(λ^0) / 0!
Where λ is the mean and e is the base of the natural logarithm.
Substituting the values, we get:
P(X = 0) = (e^-3)(3^0) / 0!
P(X = 0) = (0.0498)(1) / 1
P(X = 0) = 0.0498

b. The probability that at least 2 automobiles are sold on a particular day can be calculated using the formula:
P(X ≥ 2) = 1 - P(X < 2)
P(X ≥ 2) = 1 - (P(X = 0) + P(X = 1))
P(X ≥ 2) = 1 - ((e^-3)(3^0) / 0! + (e^-3)(3^1) / 1!)
P(X ≥ 2) = 1 - (0.0498 + 0.1494)
P(X ≥ 2) = 1 - 0.1992
P(X ≥ 2) = 0.8008

c. The probability that for five consecutive days at least one automobile is sold can be calculated using the formula:
P(X ≥ 1) = 1 - P(X = 0)
P(X ≥ 1) = 1 - (e^-3)(3^0) / 0!
P(X ≥ 1) = 1 - 0.0498

If F(-9,-4), E(-7, a) G(-2,5), and H(-6,-1) then the value of a is equal to -1, then EF is parallel to GH.

What are the parallel lines?

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

To determine if EF is parallel to GH, we need to compare the slopes of the two lines.

The slope of line EF can be found using the coordinates of points E and F:

slope of EF = (y2 - y1)/(x2 - x1) = (a - (-4))/(-7 - (-9)) = (a + 4)/2

The slope of line GH can be found using the coordinates of points G and H:

slope of GH = (y2 - y1)/(x2 - x1) = (5 - (-1))/(-2 - (-6)) = 6/4 = 3/2

For EF to be parallel to GH, their slopes must be equal. Therefore, we can set the slope of EF equal to the slope of GH and solve for a:

(a + 4)/2 = 3/2

Multiplying both sides by 2, we get:

a + 4 = 3

Subtracting 4 from both sides, we get:

a = -1

Therefore, if a is equal to -1, then EF is parallel to GH.

Mr. Morris should expect around 3672 books in the collection to have minor or major damage.

What is proportion ?

Proportion is a relationship between two quantities that expresses the fraction of one quantity in terms of the other. In other words, a proportion is a statement that two ratios are equal.

To estimate the number of books in the collection that have minor or major damage, we first need to find the proportion of books in the sample that have such damage. We can then use this proportion to estimate the number of damaged books in the entire collection.

The total number of books in the sample is:

Total number of books = 737 + 67 + 31 = 835

The proportion of books in the sample that have minor or major damage is:

Proportion of damaged books = (67 + 31) / 835 = 0.108

To estimate the number of damaged books in the entire collection, we can multiply the proportion of damaged books by the total number of books in the collection:

Number of damaged books in collection = 0.108 x 34,000 = 3672

Rounding this answer to the nearest whole number, we get:

Therefore, Mr. Morris should expect around 3672 books in the collection to have minor or major damage.

Step-by-step explanation:

In 12 minutes, the satellite travels 3,300 miles around Earth. To find how far the satellite travels around Earth in 1 hour, we can use unit conversion:

1 hour = 60 minutes

So, the number of 12-minute intervals in 1 hour is:

1 hour / 12 minutes = 5 intervals

Therefore, in 1 hour, the satellite travels:

3,300 miles/interval × 5 intervals = 16,500 miles

So the satellite travels around Earth at a distance of 16,500 miles in 1 hour.

(i)  If Jane's assumption is correct, she will not get 15 tomatoes.

(ii) If Jane's supposition about the body mass of the each tomato is wrong, she could not obtain 15 tomatoes to 1 kg of tomatoes.

What types of things are assumptions?

An presumption is something you believe to be true despite the lack of evidence. People might presume, for instance, that you are a geek if you wear spectacles, even though that is untrue.

(b) (i) If Jane's assumption is correct, then the weight of 15 tomatoes would be:

15 tomatoes × 75 g/tomato = 1125 g

Since 1 kg is equal to 1000 g, Jane would need to buy at least:

1125 g / 1000 g/kg = 1.125 kg of tomatoes

Therefore, Jane would need to ask for at least 1.125 kg of tomatoes to get 15 tomatoes if her assumption about the weight of each tomato is correct.

(b) (ii) If Jane's assumption about the weight of each tomato is not correct, it is possible that she could get 15 tomatoes with 1 kg of tomatoes, depending on the actual weight of each tomato.

For example, if each tomato actually weighs 67 g, then 15 tomatoes would weigh:

15 tomatoes × 67 g/tomato = 1005 g

This is less than 1 kg, so Jane would get 15 tomatoes with 1 kg of tomatoes.

On the other hand, if each tomato actually weighs 100 g, then 15 tomatoes would weigh:

15 tomatoes × 100 g/tomato = 1500 g

This is more than 1 kg, so Jane would not get 15 tomatoes with 1 kg of tomatoes if her assumption about the weight of each tomato is incorrect.

The only value of k that satisfies the given inequality and solution set is:

k = 0.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We are given the inequality:

1/2 < k - 4x < 2k + 8

We are also given the solution set of the inequality:

{-3 < x < 2} and {-3 < x < 7/8}

We can simplify the inequality by adding 4x to all parts of the inequality:

1/2 + 4x < k < 2k + 8 + 4x

Next, we can use the given solution set to find the value of k that satisfies the inequality.

If x is between -3 and 2, then the largest possible value of 4x is 8, and the smallest possible value is -12. Therefore:

1/2 + 8 < k < 2k + 8 + 8

or

8.5 < k < 2k + 16

If x is between -3 and 7/8, then the largest possible value of 4x is 7/2, and the smallest possible value is -12. We have:

1/2 + 7/2 < k < 2k + 8 + 7/2

or

4 < k < 2k + 23/2

The intersection of these two solution sets is:

8.5 < k < 2k + 16

and

4 < k < 2k + 23/2

Simplifying the second inequality:

4 < k < 4 + 2k + 23/2 - 2k

or

4 < k < 23/2

Therefore, k must be between 8.5 and 23/2, inclusive.

However, we also need to check if k = 0 satisfies the inequality.

1/2 < 0 - 4x < 2(0) + 8

or

1/2 < -4x < 8

or

-1/8 > x > -2

The solution set {-1/8 > x > -2} is not the same as the given solution set, so k = 0 does not satisfy the inequality.
