Mrs. Kelso and Mr. Bonham gave each of their students a small bag of colored tiles. The students each counted the number of purp

le tiles they received. The box plots display the data for both classes.
Which statement is best supported by the information in the box plots?

A) The data for Mrs. Kelso's class are more symmetrical than the data for Mr. Bonham's class.


B) The range of the data for Mr. Bonham's class is less than the range of the data for Mrs. Kelso's class.


C) The median number of the data for Mr. Bonham's class is less than the median number of the data for Mrs. Kelso's class.


D) The interquartile range of the data for Mrs. Kelso's class is greater than the interquartile range of the data for Mr. Bonham's class.

Answer: a. The range of the data for Mr. Bonham’s class is less than the range of the data for Mrs. Kelso’s class.

Step-by-step explanation:

From the box plot, we can see data for Mr Bonham's class and Mrs Kelso's class.

Interpreting the box plot:

For Mr Bonham's class, the data from the box plot is obtained as between the range of 6 and 16. This means:

6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16

Calculating the range for Mr Bonham's class,

Range = Highest - Lowest = 16 - 6 = 10

For Mrs. Kelso's class, the data from the box plot is obtained as between the range of 5 and 17. This means:

5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17

Calculating the range for Mr Bonham's class,

Range = Highest - Lowest = 17 - 5= 12

Therefore, from the calculation above, affect comparing the range of data from Mr Bonham's class to that of Mrs Kelso's class we can see that Option a. "The range of the data for Mr. Bonham’s class is less than the range of the data for Mrs. Kelso’s class." Is the correct Option.

Liliana asked her friend how many siblings they each have. Using the data plot, how many of the students have three or more sibl
Alchen [17]

Answer:

11 students

Step-by-step explanation:

We can see that there are 6 students with 3 siblings, 4 students with 4 siblings, and 1 student with 6 siblings.

Adding all of these together will tell us how many students have 3 or more siblings.

6 + 4 + 1 = 11

So, there are 11 students with 3 or more siblings.

What is −300 ÷ (−13) = and how would i write out this problem to solve?
never [62]

Answer:

  23 1/13

Step-by-step explanation:

You have done a pretty good job of writing the problem, negative 300 divided by negative thirteen. It can be translated directly to your favorite calculator (see attachment) for a solution.

If you want to perform the division by hand, the particular method of writing the problem depends on the method of division you want to use. (Several styles are taught these days). Numerous web sites and videos explain <em>long division</em> in all its detail. The second attachment shows an example where a decimal fraction result is obtained. The decimal fraction is an infinite repeating decimal with a 6-digit repeat.

For starters, you would generally convert both numbers to positive numbers, since the result of 300/13 is the same as the result of -300/-13 and positive numbers are easier to deal with.

___

<em>Comment on symbols</em>

(The symbol ÷ generally means the same thing as the symbol /. Both mean "divided by". In some cases, the symbol ÷ is given the meaning "everything to the left of it divided by everything to the right of it." This is often the case when it is used as part of a compound fraction: 3/5÷4/3, for example. The preferred representation of such a division is (3/5)/(4/3), with parentheses clearly identifying numerators and denominators.)

What is the function for a table with a domain of 5, 10, 15, 20 and a range of 40, 80, 120, and 160
kykrilka [37]
To find the range we need to find the vertex of the parabola which is at (-b/2a , y)

-b/2a would be 2/2 = 1 ... so find the y value at x = 1

12 - 2(1) - 15 = 1-17 = -16

So the vertex is at (1,-16)

Since the parabola opens upward from that point the minimum value of the range is y = -16

The range would include the point -16 so it is actually

R = [-16,infinity)

Four friends start a business and decide to share the profits evenly. Their initial investment in the business costs them a tota
Natasha2012 [34]

Answer:

$16650

Step-by-step explanation:

The initial investment in the business costs them a total of $7400.

And after one year the amount of money the business has earned is 10 times their initial investment i.e. $(7400 × 10) = $74000.

Therefore, the net profit will be $(74000 - 7400) = $66600.

So, the profit of each friend will be \frac{66600}{4}= 16650$. ( Answer )

The fuel tank of a certain airplane can hold up to gallons of fuel. Let be the total weight of the airplane (in pounds). Let be
zloy xaker [14]
A reasonable function is W = 7F + 5000


Where W is the weight of the plane and F is the number of gallons of fuel.


The domain is the set of possible values for F. That is from 0 (empty tank) to 400 (full tank).


So the domain is F = [0,400], or what is equivalente 0 ≤ F ≤ 400.


The range is the set of values of W.


The minimum value of W is when F = 0 => W = 7(0) + 5000 = 5,000.


The maximum value of W is when F = 400 => W = 7(400) + 5000 = 7,800


So the range is W = [5,000 ; 7,800], pr 5000 ≤ W ≤ 7,800.
