Which statement or statements are TRUE?
I. The data distribution is skewed
II. The interquartile range is 6
III. The median is 10
A) I only
B) II only
C) I and II only
D) II and III only
Answers
Answer: A. I only
Step-by-step explanation:
Most of the observations are on the lower end, so the distribution is skewed right. The interquartile range is indicated by the length of the box, about 14. The median is indicated by the vertical line running through the box, about 13

The given question is a typical example of mathematical puzzles. Mathematical puzzles are mathematical problem given to pupils, students for recreational experience and more.
Further ExplanationMathematical puzzles further enhance the creativity of students, as it deals with their logical reasoning.
Mathematical puzzles also has do with the practical usage of order of operations i.e. BODMAS (which is an acronym of Bracket, Of, Division, Multiplication, Addition, Subtraction) to derive solutions for existing problems.
It can be observed from the above given mathematical puzzle expression that Multiplication and Addition are in use in that order.
The two figures are multiplied and added together and then placed together to derive a final
5 + 3 = 158
5 x 3 ~ 5 + 3 = 15 ~ 8 = 158
9 + 1 = 910
9 x 1 ~ 9 + 1 = 9 ~ 10 = 910
8 + 6 = 4814
8 x 6 ~ 8 + 6 = 48 ~ 14 = 4814
4 + 4 = 168
4 x 4 ~ 4 + 4 = 16 ~ 8 = 168
Therefore,
7 + 3 = 2110
7 x 3 ~ 7 + 3 = 21 ~ 10 = 2110

the town of lantana needs $14,000 for a new playground. lantana elementary school raised $5358 lantana middle school raised $2834 and lantana high school raised 4132.
about how much more money do they need to raise?
Answers
Total money collected = $5358+$2834+4132 = $12324
Additional money needed = Total money - Money collected
=> $14,000 - $12,324
=> $1,676
So they need $1676 more money to be collected

At a local fitness center, members pay an $8 membership fee and $3 for each aerobics class . Nonmembers pay $4 for each Aerobics class. For what number of aerobics classes will the cost for members & nonmembers be the same?
Answers
Since members pay $3 for each aerobics class, we can represent this part of the equation as 3c. Members also pay a one time $8 membership fee, so we just add the 8 to the 3c:
3c + 8
Since nonmembers pay $4 for each aerobics class, we can represent this part of the equation as 4c. They do not have to pay a one time membership fee, so our equation will just be:
4c
To determine when the cost (c) of the aerobics class will be the same for both members and nonmembers, we set the two equations equal to each other:
3c + 8 = 4c
Then, we solve for c. First, the variables must be on the same side of the equation. We can do this by subtracting 3c from both sides of the equation:
8 = 1c.
Last, we divide both sides by 1. So c = 8.
This means that the cost of classes will be the same for members and nonmembers at 8 classes. If we want to check our answer, we can plug 8 back into each equation:
3c + 8
= 3 ( 8 ) + 8
= 24 + 8
= 32
4c
= 4 ( 8 )
= 32

Answers
Answer: There are 4 vowels out of the 11 total letters in the word MATHEMATICS. 4/11 is 0.3636... or approximately 36%.
This means that there is a 36% chance of drawing a vowel from the word MATHEMATICS.
Final answer:
Explanation of drawing a vowel from the letters spelling MATHEMATICS focusing on vowels A, E, and I.
Explanation:
Vowels are fundamental in the English language. When drawing a vowel from the letters that spell out MATHEMATICS, we identify the vowels to be A, E, I. Therefore, drawing a vowel from these letters could result in A, E, or I.

Step-by-step explanation:
We can change the sign of an exponent if we change sides. This means sign of exponent changes when we move the number (along with base) from numerator to denominator or from denominator to numerator.
So 10 to the power -1 will change to 10 to the power 1 if we take the whole thing to the denominator (steps shown below):

How is the following decimal number read?
28.9
A. Twenty and eight-nine tenths
B. Twenty-eight and nine hundredths
C. Twenty-eight and nine tenths
D. Twenty-eight nine
Answers
C) twenty-eight and nine tenths
Explanation:
We have two parts here, the whole number and the decimal part.
1- for the whole number, it is read normally as counting numbers. Therefore, 28 is read as twenty-eight
2- for the decimal part, it is read based on the place-value of the number. We know that the first number after the decimal point is in the tenth position. This means that 0.9 is read as nine tenths
Combining the two, we would conclude that 28.9 is read as twenty-eight and nine tenths
Hope this helps :)
Answer:
C. Twenty-eight and nine tenths.
Step-by-step explanation:
We have been given a decimal number [tex]28.9[/tex]. We are asked to choose the correct option that represents how to read our given decimal number.
Upon looking at our given decimal number we can see that it has one digit at tenth place that is 9, which represents that our number has 9 tenths.
The two digits before decimal are 2 (tens place) and 8 (ones place). These digits make 28.
Therefore, the given decimal number could be read as twenty-eight and nine tenths and option C is the correct choice.

Problem Nell's mom makes chocolate milk with 30mL of chocolate syrup for every 2 ounces of milk. Nell's dad adds 65mL of chocolate syrup for every 5 ounces of milk. Whose chocolate milk is more chocolatey?
a- Nell's Mom
b-Nell's Dad
c- They're both equally chocolately
12 POINTSS
Answers
Nell's dad: 65 mL for 5 ounces = 13 mL for 1 ounce
15 > 13
Therefore, Nell's mom's chocolate milk is more chocolately.
Answer:
(A) Nell's mom
Step-by-step explanation:
It is given that Nell's mom makes chocolate milk with 30mL of chocolate syrup for every 2 ounces of milk.
⇒For 1 ounce of milk, she will make chocolate milk=[tex]\frac{30}{2}=15mL[/tex]
Also, it is given that Nell's dad adds 65mL of chocolate syrup for every 5 ounces of milk.
⇒For 1 ounce of milk, he will make chocolate milk=[tex]\frac{65}{5}=13mL[/tex]
Since, Nell's mom made 15mL of chocolate milk and his dad made 13mL of chocolate milk, thus Nell's mom made chocolate milk more chocolatey.
Hence, option A is correct.

Final answer:
To find out how many times more massive than the Sun a black hole with a mass of 7.36 x 10³⁶ kg is, divide its mass by the mass of the Sun which is approximately 1.99 x 10³⁰ kg. The answer is 3.7 x 10⁶ times more massive than the Sun.
Explanation:
Scientists believe that there is an extremely massive black hole at the center of the Milky Way. To find out how many times more massive than the Sun a black hole with a mass of 7.36 x 10³⁶ kg is, you can divide its mass by the mass of the Sun. So, 7.36 x 10³⁶ kg / 1.99 x 10³⁰ kg = 3.7 x 10⁶ times more massive than the Sun.

According to this, we can say that:

{4s+f=13
This is a system.
We can then use elimination to solve and isolate the variable:

- (4s+f=13)
We can then subtract and conclude that:
-4f=2
-f=1/2
f=-1/2
A snail moves 1/40 of a mile in 3/4 of an hour. If the snail continues at this pace, how far, in miles, does it move in one hour?
The answer is .03 or 1/30 but, Idk how to explain my answer.
Answers
A snail moves 1/40 of a mile in 3/4 of an hour. If the snail continues at this pace, how far, in miles, does it move in one hour?
In [tex] \frac{3}{4} [/tex] hour snail moves [tex] \frac{1}{40} [/tex]miles
[tex] \frac{3}{4} hour = \frac{1}{40} [/tex] miles
Let us multiply by 4 on both sides, so that we can get the distance to be traveled in 1 hour.
So, [tex] \frac{3*4}{4} hour=\frac{1*4}{40} [/tex] miles
[tex] \frac{3*1}{1} hour=\frac{4}{40} [/tex] miles
Now to get distance in 1 hour, Let us divide by 3 on both sides
[tex] \frac{3}{3} hour=\frac{1}{10*3} [/tex] miles
[tex] \frac{1}{1} hour=\frac{1}{30} [/tex] miles
In 1 hour, the snail travels [tex] \frac{1}{30} [/tex]miles
