Answer:

15 units

Step-by-step explanation:

You failed to start the end points of the frequency polygon from a x-value of 0.

First of all, we would determine the midpoint of the data set as follows:

0 < t ≤ 5 = (0 + 5)/2 = 2.5.

5 < t ≤ 10 = (10 + 5)/2 = 7.5.

10 < t ≤ 15 = (10 + 15)/2 = 12.5.

15 < t ≤ 20 = (15 + 20)/2 = 17.5.

In order to draw a frequency polygon for the given data set, we would construct the frequency table as follows:

Time, t minutes                                      Frequency_

0 < t ≤ 5                                                        7

5 < t ≤ 10                                                       8

10 < t ≤ 15                                                      6

15 < t ≤ 20                                                     4

Finally, we would connect the end points of the data set on the frequency polygon by starting from a x-value of 0 as shown in the image attached below.

Answer:Typically 2 sides and 1 angle need to be given in order to determine a unique triangle. Alternatively 1 side and 2 angles, or the Cartesian coordinates of three vertices, or the area, base, and height. In any case 3 pieces of information.

Step-by-step explanation:

Answer:

You can establish the size and shape of a triangle if you know two angle measurements and the length of the side between the angles (ASA). Two or more triangles are congruent if their corresponding parts coincide through the ASA criterion.

Answer:

12/5

Step-by-step explanation:

His fish tank is 4 1/2 gallons of water. It takes him 1 7/8 minutes to fill it. So you need to find out how many gallons you can pour in 1 minute. You can eliminate A because he is filling more than 1 gallon per minute. You can divide   4.5 (4 1/2) by 1.875 (1 7/8). You get 2.4. Convert it back to a fraction, and you get 2 4/10. Simplify the fraction 2/5. Now convert it to an improper fraction. 12/5.

Answer:0.27

Step-by-step explanation:

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

4 / 15 = 0.266

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 266

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule II applies, so 4/15 (or 0.266) rounded to the nearest hundredth in decimal format is:

0.27

Answer:

The probability of the guess being correct is 1/150.

Step-by-step explanation:

The information provided for the game Clue is:

Now it is provided that at some point the possibilities have been narrowed down to 5 people, 5 weapons, and 6 rooms.

The number of ways to select a guilty person from the 5 selected people is,

n (P) = 5

The number of ways to select a weapon from the 5 selected weapon is,

n (W) = 5

The number of ways to select a room from the 6 selected rooms is,

n (R) = 6

Then the total number of random guesses is,

N = n (P) × n (W) × n (R)

   = 5 × 5 × 6

   = 150

And only one of these 150 guesses is correct.

So, the probability of the guess being correct is 1/150.

Step-by-step explanation:

The measure of the angle supplement of TOK is 131°.

Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.

Now the given angle is,

m TOK = 49°

Let the supplement of 49° be x.

Now, 49° + x = 180°

Taking alike terms together we get,

⇒ x = 180° - 49°

Solving we get,

⇒ x = 131°

which is the required supplement of TOK.

Thus, the measure of the angle supplement of TOK is 131°.

If repetitions of colors are not allowed, there are 9,072 possible selections of collars for Dave's 5 cats.

If repetitions of colors are not allowed, we can use the concept of combinations to determine the number of selections of collars that are possible for Dave's 5 cats.

Since there are 9 different colors available and repetitions are not allowed, for the first cat, Dave can choose from 9 different collars.

For the second cat, there are 8 remaining colors to choose from. Similarly, for the third cat, there are 7 remaining colors, and so on.

To find the total number of selections, we multiply the number of choices for each cat together:

Total selections[tex]= 9 \times 8 \times 7 \times 6 \times 5[/tex]

Calculating this expression:

Total selections = 15120

Therefore, there are 15,120 possible selections of collars if repetitions of colors are not allowed for Dave's 5 cats.

It's important to note that the calculations assume that the order of the cats does not matter.

If the order of the cats' collars matters, the total number of selections would be higher and would involve using the concept of permutations rather than combinations.

This shows that the Probability distribution of the scores of a randomly selected senior executive is correct.

Probability distribution for the job satisfaction score of a randomly selected senior executive

A probability distribution is a table of all possible values of a variable (like scores) and the likelihood of their occurrence.

The percent frequency distributions of job satisfaction scores for a sample of information systems (IS) senior executives are given as:Job Satisfaction Score    IS Senior Executives (%)1 5%2 9%3 38%4 42%5 6%

To determine the probability distribution of the scores for a randomly selected senior executive, we convert the percentage distribution into a probability distribution by dividing the percentage frequency of each score by 100. Then, we add up the probabilities of all scores to verify that they sum up to 1 (or 100%).

Therefore, the probability distribution is:

Job Satisfaction Score     Probability of Occurrence1                                    

 0.052                                      0.093                              

  0.384                                      0.425                                      0.06

The sum of the probabilities of all scores is 0.05 + 0.09 + 0.38 + 0.42 + 0.06 = 1.00 or 100%.

This shows that the probability distribution of the scores of a randomly selected senior executive is correct.
