What is the third quartile of this data set ? 14,18,20,21,25,32,40,44,48

kotykmax [81]

Step-by-step explanation:

Step 1 :

Given data set - 14,18,20,21,25,32,40,44,48

We need to get the 3rd quartile

Step 2 :

To find the quartile's , we have to divide the data set into 4 equal quarters.

The 3rd cut will give the 3rd quartile

Step 3:

The median of this data set is at 25, there are 4 numbers below and above it.

Now we take the 2nd half of the set , after the median and take the median of it.

There are 4 numbers in the 2nd half 32,40,44,48. Cutting this into 2 , we have the cut to fall between 40 and 44. Hence taking the average of this will give the 3rd quartile.

The average of 40 and 44 is 42 .

Hence the 3rd quartile is 42.

One canned juice drink is 15% orange juice; another is 5% orange juice. How many liters of each should be mixed together in orde

grandymaker [24]

F = 15%
v = 5%
0.15f + 0.05v = 0.14*10
15f + 5v = 140
3f + v = 28
f + v = 10 (total volume)
---------- Subtract
2f = 18
f = 9 liters of 15%
v = 1 liter of 5%

Data:

15 16 14 15 19 17

n=6 points

sum is 96

mean is 96/6 = 16

Now we look at the absolute deviations, each of which is the absolute value of a score minus the mean, basically the distance of the score to the mean .

Scores 15 16 14 15 19 17

AbsDev 1 0 2 1 3 1

The sum of the absolute deviations is 8 and there are six of them so the

Mean Absolute Deviation = 8/6 = 4/3

Answer: 2. 8/6

Please select the best answer and click submit Solve kx-4=9 for x

shepuryov [24]

Answer:

Option B. $x = \frac{13}{k}$ .

Step-by-step explanation:

The given equation is kx - 4 = 9

We will add 4 on both the sides of the equation

kx - 4 +4 = 9 +4

kx = 13

Now we will divide by k on both the sides of the equation

$\frac{1}{k}(13x) = \frac{1}{k}13$

$x = \frac{13}{k}$

Therefore Option B x = 13/k is the right answer.
