What is the interquartile range of this data set?

{18, 17, 10, 25, 20, 20, 30, 18, 18, 30, 25}



Enter the answer in the box.

Answers

Answer 1

The interquartile range of the data set is 7.

Step-by-step explanation:

The given set of data is {18 , 17 , 10 , 25 , 20 , 20 , 30 , 18 , 18 , 30 , 25}

Arrange the data in ascending order:

10 , 17 , 18 , 18 , 18 , 20 , 20 , 25 , 25 , 30 , 30

Divide the data in two equal parts:

(10 , 17 , 18 , 18 , 18), 20 ,(20 , 25 , 25 , 30 , 30)

Divide each parenthesis in 2 equal parts:

(10 , 17), 18 ,(18 , 18), 20 ,(20 , 25), 25 ,(30 , 30)

Now we can say that,

Q₁ = 18 , Median = 20 , Q3 = 25

Interquartile rage of a data is :

I.Q.R. = Q3 - Q1

I.Q.R. = 25-18 = 7

Therefore the interquartile range of the data set is 7.

Hope this helped!

The product of the fractions 3/11 and 3 1/4 is 39/44.

Here, we have,

To find the product of the fractions 3/11 and 3 1/4,

we need to convert the mixed number 3 1/4 to an improper fraction and then multiply the two fractions.

Step 1: Convert the mixed number to an improper fraction.

3 1/4 = (4 * 3 + 1) / 4 = 13/4

Step 2: Multiply the two fractions.

(3/11) * (13/4)

= (3 * 13) / (11 * 4)

= 39 / 44

So, the product of the fractions 3/11 and 3 1/4 is 39/44.

Answer:

LCD=5 Final answer= 5/5 -> 5/1 -> to 5

Step-by-step explanation:

First, find the LCD(least common denominator) which is 5. This is done listing the multiples of each number in this case the lowest number is 5.

3/5 will stay the same but for 1/10 you need to convert it to the fraction 2/5 Next add the fractions together to get 3/5 + 2/5 = 5/5 of 5/1 or just 5

Solve 6(2/3x-3)>8. The thing says the question is too short and to add at least 20 more words so ignore this sentence, it's only to submit

Answers

Answer:

[tex]6(\frac{2x}{3} -3) > 8\\[/tex]

Solve brackets

6(0.66x-3)>8

Multiply 6 with values in the bracket

So, 6x0.66x and 6x-3

4x- 18> 8

Since 4x and 18 are unlike terms, we will take 18 onto the other side, thus:

4x>8+18

4x>26

Now to find the value of x, divide 4 on B.S

x> [tex]\frac{26}{4}[/tex]

X> 6.5

OR in 'fraction form'

X>[tex]\frac{13}{2}[/tex]

Hope this helps :D

6(2x/3 - 3) > 8
12x/3 - 18 > 8 distribute the 6
4x - 18 > 8 reduce fraction
4x > 26 add 18 to both sides
x > 6.5 divide both sides by

What is the value of x when 5x=6.5?

Answers

Answer:

x= 1.3

Step-by-step explanation:

First, separate x, by dividing both sides by 5

[tex]5 \div 5x = 6.5 \div 5[/tex]

which equals

x= 1.3





Answer: 1.3

Step-By-Step explanation:
5x=6.5
5x/5=6.5/5
x=1.3


We have to get X alone but to do that we had to cancel 5 and bring to the other side. So we did the opposite from what it said to do so instead and 5*x we divided. But we cannot just do that on one side so we had to do it on the other which ended us of with x=1.3

Step-by-step explanation:

The sample space is the range of values a random variable may have. In this process, the random variable will have the value of one of the letters shown. That is, it will be one of {A, B, F, K, S}.

The sample space is A, B, F, K, S.

If Erina meets her goal, how many yards will Erina run each day in the third week of her training? Round the answer to the nearest hundredth. Enter the answer in the box _____ yards

Answers

3400 yards because it works please give Brainly

During the first week of her training, she runs 200 meters.  On the second week, she plans to run 50% more.  

Now, how do you calculate this?

To increase 200 meters by 50%, multiply by 1.5

The second week she pans to run 450 meters.

Since there are only 3 weeks, do it again!

The thrid week, she plans to run 675 meters.

Since she runs the same ammount each day of the week, the calculation is simple.

7(200) + 7(450) + 7(675)

In these three weeks, she runs 9275 meters.

OR, she runs 10143.26 yards.
