Answer 2

Final answer:

For Amo, the median (89) is higher than the mean (84.6), and for Javier, the mean (77.4) is higher than the median (68). Thus, Mr. Malloy should use the median for Amo and the mean for Javier for the best possible grades.

Explanation:

To determine the best possible grade for both Amo and Javier, we first need to calculate their mean and median scores. The mean is calculated by adding all the test scores together and dividing by the number of tests. The median is the middle score when all scores are listed in ascending order. If there is an even number of scores, the median is the average of the two middle scores.

Amo's Scores: 97, 92, 89, 55, 90
Javier's Scores: 68, 97, 65, 92, 65

For Amo, we calculate the mean as follows:
(97 + 92 + 89 + 55 + 90) / 5 = 84.6

The median for Amo would be the third score since there are five tests, which is 89.

For Javier, we calculate the mean as follows:
(68 + 97 + 65 + 92 + 65) / 5 = 77.4

The median for Javier would also be the third score, which is 68.

Now, comparing Amo's mean and median, we see that the median (89) of Amo's test scores is higher than the mean (84.6). Therefore, for Amo, Mr. Malloy should use the median.

Looking at Javier's mean and median, we see that the mean (77.4) of Javier's test scores is higher than the median (68). So, for Javier, Mr. Malloy should use the mean.

The teacher should use the median for Amo and the mean for Javier for the best possible grade.

A. 30
B. 23
C. 6
D. 33

Answers

c. the outlier will most likely be the answer to this question

Answer: C. 6

Step-by-step explanation:

A box-plot mainly represents a five number summary of :

1) lowest data value 2) largest data value 3) first quartile 4) second quartile (Median) 5) third quartile.

The modified version of box-plot displays the outliers of the data by a point if present,

Since 6 is the outlier of the data.

Therefore the 6 is the value which would be represented by a point in a modified box plot.

Answers

Hello,

If you are starting with C as point (1, 1) all you have to do is multiply the coordinates by the scale factor. In this case, the scale factor is 0.25.

So we have: 0.25 x 1 = 0.25

Our new point C' will be (0.25, 0.25)

Ben believes that most of the automobiles in his neighborhood are SUVs. He does a house-to-house survey of parked cars. He surveys 45 cars and only 8 of the cars he finds are SUVs. Yet fully 50% of the town’s automobiles are SUVs. What is the MOST LIKELY explanation for these two facts? A) Ben’s sample is too small to be representative of the entire town. B) SUVs are sometimes hard to distinguish from non-SUVs and Ben made errors. C) Most of the SUVs were on the road, and less popular models were left at home. D) Ben only looked at parked cars instead of asking residents what kind of car they drive.

Answers

I had this question last year I believe it's C but not 100% sure.

Answer:

It’s A Guys!

Step-by-step explanation:

All of the explanations are possible, but surveys need to be done in a way which results in a representative sample. Ben’s sample was not representative of the entire town.

He only asked in his neighborhood not in his whole town. C just doesn’t make sense. B is highly unlikely mathematically speaking, and D was kind of illogical. I thought of picking D, but comparing the two, A was the better answer.

Janine wishes to conduct a poll to predict how many dance club members will vote for her for club president.

Which polling methods are likely to be biased?

Select each correct answer.

A. Five of Janine's friends are selected and asked for whom they intend to vote.

B. From a list of all club members, 25 members are selected at random and asked for whom they intend to vote.

C. Janine chooses 5 members that plan on voting for her and asks each to select another 5 members. These 25 members are asked for whom they intend to vote.

D. Every 10th club member from a list of all members is selected and asked for whom the member intends to vote.

Answers

"Bias" means someone shows inclination towards someone or something because of the relationship that person has with that thing or person.

In this case, since Janine has friends that are also in the dance club, they are more likely to vote for her as president because they are friends with her. So, answer A is likely to be biased because the five people sampled are her friends.

Answer C is also biased because the sample chosen already plan on voting for her as president, and they are more than likely to find others who plan to vote for her.

Julio is in Colorado exploring part of the Denver Zoo as shown he starts at the felines exhibit and travels 3 unit to the right and 5 units up at which exhibit is Julio located at the felines exhibit is located at (3,1) what are the coordinates of Julio's new location

Answers

Starting with his original coordinates (3, 1), going 3 units right gives us (3+3, 1) = (6, 1). Going 5 units up then gives us (6, 1+5) = (6, 6) for his new location.

Final answer:

To find Julio's new location at the Denver Zoo, we add his horizontal and vertical movements to his starting coordinates. After moving 3 units to the right and 5 units up from the felines exhibit at (3,1), Julio's new location is at coordinates (6,6).

Explanation:

The student is asking about a basic coordinate geometry problem. Julio is at the felines exhibit at coordinates (3,1). To find Julio's new location after traveling 3 units to the right and 5 units up, we add the horizontal and vertical movements to his starting coordinates.

The movement to the right corresponds to an increase in the x-coordinate, while the movement up corresponds to an increase in the y-coordinate. Starting from the point (3,1), moving 3 units to the right means the x-coordinate changes from 3 to 3 + 3 = 6. Moving 5 units up means the y-coordinate changes from 1 to 1 + 5 = 6. Thus, Julio's new coordinates are (6,6).

How do you work out this question:
Ravi had 237 marbles more than Elliott had. Ravi gave Elliott 165 marbles. Who had more marbles in the end? How many more?

Answers

Ravi had more marbles because if he gave Elliot 165 then you subtract 237-165 which is 72 which means now Ravi has less marbles but he has more then Elliot and now he has 72 marbles more then Elliot

After mathematics calculations, it is determined that Elliott ends up with more marbles than Ravi by 93 marbles after Ravi gives him 165 marbles.

The question involves Ravi and Elliott and the number of marbles they each have initially and after a certain transaction. To solve the problem, we start with the given information:

1. Ravi originally had 237 marbles more than Elliott.

2. Ravi gave Elliott 165 marbles.

Let's denote the number of marbles Elliott had initially as E. According to the information provided, Ravi had E + 237 marbles.

After Ravi gave Elliott 165 marbles, Elliott's new total would be E + 165, and Ravi's new total would be (E + 237) - 165.

Simplifying Ravi's new total, we get E + 237 - 165 = E + 72.

Now we compare both totals:

Elliott's total after receiving marbles: E + 165 Ravi's total after giving marbles: E + 72

Clearly, Elliott now has more marbles than Ravi by 165 - 72 = 93 marbles.

So Elliott has more marbles, and he has 93 more than Ravi once the transaction is completed.

Answers

The 3 number should be: 0, 1 and -1.

Final answer:

The three numbers that are their own cube roots are 0, 1, and 8.

Explanation:

The three numbers that are their own cube roots are 0, 1, and 8.

A cube root of a number is a value that, when raised to the power of 3, gives the original number. For example, the cube root of 8 is 2 because 2³ = 8. Similarly, the cube root of 0 is 0 and the cube root of 1 is 1.

So, the numbers that are their own cube roots are 0, 1, and 8.

Carl downloaded 15 songs of country music, 20 of rock, 5 of classical and 10 of world.

If we want to know the total of songs, we just need to sum them all:

Rectangle A has side lengths of 6 cm and 3.5 cm. The side lengths of rectangle B are proportional to the side lengths of rectangle A.
What could be the side lengths of rectangle B?

A. 3cm and 1.75cm
B. 5cm and 2.5cm
C.7 cm and 7cm
D. 12cm and 5 cm
E. 5.25cm and 9cm

Answers

To determine whether or not these are proportional, take the two side lengths that are given and create a ratio. 6cm:3.5cm. I suggest writing this in fraction form to better see the equivalency. If you divide both 6cm and 3.5 cm by 2, you create an equivalent ratio of 3 cm:1.75cm. This is answer A. There is another correct answer too! If you take 6cm:3.5cm and multiple both by 1.5, it will create an equivalent ratio of 9cm:5.25 cm (answer choice E), just in a different order.

Additional money needed = Total money - Money collected
