Answer:

Lower boundary of 46 = 33

Lower boundary of 59 = 47

Lower boundary of 72 = 60

Lower boundary of 85 = 73

Step-by-step explanation:

Since the difference between each of the two successive numbers is 13. This implies that the difference between the upper and the lower boundaries for each of the class is 12.

Therefore, we have to subtract 12 from each of the upper boundary given the question to obtain their lower boundary as follow:  

Lower boundary of 46 = 46 - 12 = 33

Lower boundary of 59 = 59 - 12 = 47

Lower boundary of 72 = 72 - 12 = 60

Lower boundary of 85 = 85 - 12 = 73

Note:

It can be observed that the lower boundary of each upper can also be obtained by adding 1 to the immediate previous upper boundary. But, we adopt the above method in order to get the lower boundary of 46 since there is immediate previous upper boundary for 33 that is included in the question. With the method used above, one get as many lower and upper boundaries as one wants.

(07.06) There are currently 4 people signed up to play on a baseball team. The team must have at least 9 players.
beks73 [17]

A graph which includes the possible values for number of people who can still sign up for the team is: B. number line with closed circle on 5 and shading to the right.

<h3>What is a number line?</h3>

A number line can be defined as a type of graph with a graduated straight line which contains numerical values (positive and negative numbers) that are placed at equal intervals along its length.

Let the number of people who can still sign up for the team be represented by x. Thus, the inequality is given by:

x + 4 ≥ 9

x ≥ 9 - 4

x ≥ 5.

This ultimately implies that, there could be five (5) or more people that can still sign up for the team and a graph which includes these possible values is a number line with closed circle on five (5) and shading to the right because it can get larger.

Greg has 4 shirts: a white one, a black one, a red one, and a blue one. He also has two pairs of pants, one blue and one tan. Wh
alexgriva [62]

The distribution of the pants and the shirts illustrates probability

The probability that he winds up wearing the white shirt and tan pants is 1/8

<h3>How to determine the probability?</h3>

The number of shirts is given as:

Shirts = 4

The number of pants is given as:

Pants = 2

The probability that he winds up wearing the white shirt and tan pants is then calculated as:

P = P(White shirt) * P(tan pant)

This gives

P = 1/4 * 1/2

Evaluate the product

P = 1/8

Hence, the probability that he winds up wearing the white shirt and tan pants is 1/8

In a computer instant messaging​ survey, respondents were asked to choose the most fun way to​ flirt, and it found that ​P(D) =0
ikadub [295]

Answer:

P(Dᶜ )=0.41

Step-by-step explanation:

In the survey, the event D is the event of people who prefer to flirt directly in person.

Given that P(D)=0.590.

If someone is selected randomly, the probability that the individual prefers to flirt directly in person is 0.590.

If the person does not like to flirt in person, the probability of it will be the complement of event D.

From Probability Theory,

P(D)+P(Dᶜ )=1

0.590+P(Dᶜ )=1

P(Dᶜ )=1-0.590=0.41

The probability that the selected person does not like to flirt in person is 0.41.
