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.

PLEASE HELP!!!!! I HAVE A DEADLINE !!!!

Answer:

V_rocket = 44 $\pi$ ft^3 = 138.2 ft^3

Step-by-step explanation:

Volume of cone

V_cone = (1/3)*( $\pi$ *(radius^2))*h

radius = 2ft

h = height of the cone = 3 ft

pi = 3.1416

V_cone = 4 $\pi$ ft^3

Volume cylinder

V_cylin = ( $\pi$ *(radius^2))*h_cyl

h_cyl = height of the cylinder = 10 ft

V_cylin = 40 $\pi$ ft^3

Volume rocket

V_rocket = V_cone + V_cylin = 4 $\pi$ ft^3 + 40 $\pi$ ft^3

V_rocket = 44 $\pi$ ft^3 = 138.2 ft^3

How many different phone numbers are possible in the area code 503, if the first number cannot start with a 0 or 1

ElenaW [278]

Answer:

8 X 10^(9)

Step-by-step explanation:

Originally we have 10 digit phone numbers excluding the area code.

For each face value we have these in store: 0,1,2,3,4,5,6,7,8,9 (total 10)

But if we exclude 1 and 0 for the first digit, we are left with 8 digits.

8P1 X .......

In a phone number, digits can repeat so we can choose out of these 10 numbers freely after this.

8P1 X 10P1 X 10P1 X...

Adding the area code while assuming 10P1 is just 10...we get:

1 X 1 X 1 X 8 X 10^(9)

= 8000000000

Very interesting question, thanks for the opportunity!

1001112 = [ ? ]10<br> ?<br> what number belongs where the question mark is

EleoNora [17]

I suppose you're supposed to convert 100111 from base 2 to base 10. We have

$100111_2=2^5+2^2+2^1+2^0=32+4+2+1=39_{10}$

so the missing number is 39.
